This is normally accomplished through frequency regulations adopted by the government. Considering the safety aspects, many governments have made it mandatory to have a license for operating a CB radio.

The signals sent into the air do not stop at the borders; therefore, every country should have the proper rules set up for planning and managing the radio signals so that one does not interfere with another. If this fails, the CB radio service is useless. Therefore, the installation and use of CB radios should by done with someone with a valid license, preferably one issued by a government agency. The agency manages the radio signal spectrum in such a manner that they are available to those who need them.

In the UK, the agency that regulates the use of CB radio is a subdivision of the department of trade and industry. They manage the CB radio spectrum of the UK both nationally and internationally. CB radios can be used only with a valid license or under the supervision of a license holder. OAP networks, Girls Guides and Scouts are exempted from having a license. The license is issued by the radio-licensing center in the UK. Other countries have other agencies that issue CB radio licenses.

As noted above, the user either should have a valid license to operate or be under the supervision of a license holder. Supervision by a licensee stipulates that both the licensee and the non-license holder should be in close proximity. However, genuine cases of group operations are exempt from direct supervision. Normally, the license is issued in the name of the CB radio license holder. Individuals under the age of 14 are not issued a license.

A license is still required for the reception of CB signals, even without transmission. Walkie-talkies are exempted from licensing, but they do need to conform to the agency directives on equipment. Taxi drivers should be licensed individually and the taxi company must comply with all the rules of CB radio service. Normally the license is valid for one year, after which it must be renewed for further use. If caught using the license for illegal activity, the agency may cancel the license. http://www.information-finers.com http://www.auto-tips-tools.com ]]> http://www.artwoo.com/article/2-way-radios http://www.artwoo.com/article/2-way-radios#comments Fri, 19 May 2006 15:32:02 +0000 mobile radio servicefamily radio service2 way radiosradio signalsgmrs licenseradio frequencyradio frequencies http://www.artwoo.com/article/2-way-radios 2 Way Radios

If you are in the market for 2 way radios for personal use, you have an immediate and important choice to make: What radio frequency band do you require?

Frequency! 2 way radios obviously utilize 'wireless' communication methods so when using a 2 way radio you are transmitting and sending your message through the air -- the same air that is currently carrying television signals, commercial radio signals, Ham radio signals and literally thousands of signals from other private 2 way radios. The Federal Communications Commission (FCC) has the job of controlling all of these communication signals so they don't run into each other; to accomplish this they have reserved frequency bands for use by certain types of communication (signal sending) devices. There are two frequency bands in use for recreational 2 way radios, these are called Family Radio Service (FRS) and General Mobile Radio Service (GMRS).

In 1996, the FCC reserved a set of radio frequencies they called the Family Radio Service (FRS) band, specifically for short-range 2 way radios (radios that operate no more than 2 miles away from each other) with a small power output (up to 500 milliwatts or one-half watt).

About fifty years before the FCC created the FRS band they had reserved a set of frequencies for higher power 2 way radios that operated over a longer range this is the General Mobile Radio Service (GMRS) band. The GMRS band is for radios with a power output between one and five watts and a range over 2 miles. The FCC regulates the 2 way radios that operate on the GMRS band and requires users of this type of radio to obtain a license and pay a fee. The GMRS license is good for five years and costs $80.00; the license must be obtained by an adult (the radios operating under the license may be used by minors but only with the licensed adult's knowledge and permission). Go to the FCC's Internet page at: http://wireless.fcc.gov/services/index.htm?job=service_homeandid=general_mobile for more information on GMRS licensing.

When buying 2 way radios, your choice is between a set of radios that operates only on one of these frequency bands or a set of radios that is able to operate on either one of these frequency bands. This determination will obviously have to be made based on the maximum distance the radio users will be from each other. If the radios are to be used within two miles of each other, FRS will be the best (and least expensive) choice. If a greater distance is consistently required, 2 way radios that operate on the GMRS frequency band will be required. If the need for distance is uncertain or if you want the option of occasionally transmitting up to five miles a FRS/GMRS hybrid is the radio set to choose. http://twowayradioshq.com Find out more about Two Way Radios. ]]> http://www.artwoo.com/article/hd-radio http://www.artwoo.com/article/hd-radio#comments Mon, 21 Jul 2008 15:01:18 +0000 high quality soundcrisper soundhd radioanalog signalsdigital signalsexperience userstraditional radio http://www.artwoo.com/article/hd-radio HD radio. HD radio is an easy way to upgrade both FM and AM channels. Instead of receiving analog signals, individuals with HD receive digital signals. What this means, is a clearer, crisper sound that is closer in quality to a CD then to traditional, FM radio.

If you are an individual that listens to AM radio stations but are disappointed and annoyed with the typical, lower quality sound, this will enable your AM radio listening experience to be very similar to your FM listening experience. This is a huge upgrade in itself. You also no longer have to worry about the signal fading or the static that often breaks up your favorite shows that are played on AM radio.

You also get more information, and then you would by simply listening to traditional radio. You'll be able to receive the name of the artist and the titles of every song that is played. This enables you to go out and purchase the CD or download MP3s anytime that you hear a song that you like.

You also will have more options, because HD radio does come with multi-casting. This allows you to listen to a lot more stations and DJ's. Another very neat feature of HD radio is that it allows users to tag songs so that they can go on and buy them from Itunes at a later time.

HD radio was created IBiquity digital and it allows radio stations to buy a license to this technology. Another advantage of HD radio is that if an individual is no longer pleased with it or no longer finds it necessary, they can go back to listening to the analog signal. This is a bit different from HDTV, because in a few years, individuals will not have a choice, because the analog signal will be turned off permanently. This is not the case with HD radio.

HD radio allows for a very advanced, clear and informative listening experience. Users can listen to their favorite shows and even additional channels. They are also able to get artists and song titles of all songs that are played. This gives them the opportunity to identify an artist and then go out and purchase the album, if they feel so inclined. HD radio is also an excellent choice for individuals that listen to a lot of AM radio. It allows them to finally be able to listen to it clearly. HD radio involves using a digital signal instead of the old traditional analog. This allows for a listening experience that is much closer to what would expect when listening to a CD. The music will have much more clarity and will have a much higher quality. If you are interesting in purchasing HD radio, don't worry, it's free. You will however, have to pay for the HD tuner which isn't too much of a hassle or expense though.Auto TransportVehicle Transport]]> http://www.artwoo.com/article/hd-radio-good-and-bad-news-for-listeners http://www.artwoo.com/article/hd-radio-good-and-bad-news-for-listeners#comments Tue, 16 Oct 2007 02:30:01 +0000 hd radioradio broadcastersradioshackfm radioterrestrial radioradio 96factory radio http://www.artwoo.com/article/hd-radio-good-and-bad-news-for-listeners HD Radio, it's the hot digital technology that's being pushed by radio broadcasters as the next big thing and the savior of terrestrial radio.

The Good

First, the good news. HD Radio does sound better than regular radio. In fact, HD AM sounds almost as good as FM radio, and FM sounds almost as bright, clear and interference free as if you were listening to a CD. And because HD is digital, broadcasters can squeeze more signals into the same frequency. This allows them to broadcast different programs on what they're calling HD2 channels. For example, an oldies station could program contemporary CandW on its normal frequency, and old-time CandW on its HD2 channel.

More good news is that fact that, depending on who you believe, there are now either 1,300 to1,500 stations in the U.S. that are broadcasting HD Radio.

The difference? It's that he HD Radio Alliance claims there are 1,500 HD stations, but the FCC has only 1,300 licenses on file.

The bad news

While HD Radio may sound great and while there at least 1,300 stations broadcasting HD Radio, you can't hear them. That is, not unless you purchase an HD radio. And HD radios tend to be expensive. There is only one, inexpensive, entry-level tabletop available, the Radiosophy HD100 at $99.95. The next step up is RadioShack's Accurian HD Radio, which usually sells for about $199 and a Sony unit at $199.95. Beyond that, there is the Sangean HDR-1 with a manufacturer's suggested retail of $249, and then it's pretty much into the stratosphere of $300-plus.

Want HD radio in your car? The situation there is even worse. There are very few HD car radios available and most of them are only tuners and must be connected to your existing factory radio =96 an ugly solution at best.

The ugliest part of th HD2 channels is that the programming =96at least so far =96 is hardly good enough or creative enough to warrant buying a HD radio.

What makes it ugly is that the broadcaster could be using HD2 channels to do something really exciting as broadcasters have in Great Britain, where digital radio has just skyrocketed. Unfortunately, here in the U.S., most broadcasters have chosen to use their HD2 channels as just "variations on a theme," or variations of their regular programming (see rock station example, above).

So, what's the future of HD Radio? At this point, it doesn't seem great, especially when you compare it to satellite and Internet radio. But as they used to say, "stay tuned for more" because it could get brighter. Douglas Hanna is the editor and publisher of the highly popular website, http://www.hd-radio-home.com, which he believes is the Internet's number one site for fair and balanced news about HD radio. He is a long-time radio listener and unabashed radio fan who has been following HD Radio for more than two years. ]]> http://www.artwoo.com/article/what-you-should-know-about-satellite-radio http://www.artwoo.com/article/what-you-should-know-about-satellite-radio#comments Sun, 14 May 2006 18:32:05 +0000 satellite radiobroadcast radiohd tvshowtimehbocommercialscoast to coast coverage http://www.artwoo.com/article/what-you-should-know-about-satellite-radio Satellite Radio has become a very popular alternative to broadcast radio since its first release. It did take a while for the two competitors of satellite radio, Sirius and XM, to begin gaining customers. Equipment was expensive and bulky. There is also a monthly fee for the service, where broadcast radio is free. Satellite does have a few advantages against broadcast that helped it gain momentum more each year. There are very few channels on satellite radio that have commercials. This is very similar to premium cable television like HBO or Showtime...they cost extra but have no commercials. Another great feature Satellite Radio offers is quality that you cannot find in broadcast radio. Satellite radio is a digital signal that sounds cleaner and has virtually no static because with digital signals you either have close to full quality or nothing at all. Satellite also offers coast to coast coverage so you do not have to search for a local station when you travel.

Recent technology moves have helped the receiver end of satellite radio tremendously. Car manufacturers now offer satellite equipment built in to new cars so that there is nothing to buy, just the monthly service fee. Some car companies like GMC only offer XM capability, but many companies offer you to choose either but not both. Car manufacturers also offer much more high end stereos that can utilize the benefits of a digital signal. They use this as a sales pitch to show how good their stereos really are.

Satellite does have new competition that is broadcast for free like analog radio. HD Radio will be broadcast by many local stations in the near future offering better quality than satellite radio. This is much like television stations that broadcast HD TV locally. There are still commercials, but clear sound and music information about artists is available by any HD Radio equipped stereo. Only the future will tell if people are willing to shell out the dough to avoid commercials.

This becomes a salient factor as revenues and takings are contingent on forex exchange signals. Currency trade signals are known to be a wide array of information coming directly from various trading resources. In the early years, trading forex was subject to major complexities as it mainly used tickers as form of transmission and information were conveyed through communication lines such as the telephone and radio. At present, all these have been wiped out as the advent of new technology and the internet provided all the means for a better trade. This also calls for beginner traders to acquire the utilization of real time trade signals for a far better upshot.

Forex signals act as the fortitude and foundation of the forex market. Without these signals information will be thwarted paving the way to a possible downfall of the forex market. It would then be a complex state to generate proper trade as the buying and selling of currencies become even more complicated. The use of currency signals allows a trader to discern the movement of the trade market. This involves proper timing of when to enter and exit the trade market without any traces of profit loss. To put simply, the foreign exchange signals act as the determiner or informer sending signals to a trader if the market is at a trader's advantage.

The forex signals are a good training ground for novice traders. This should be the starting point of all your dealings as every trade relies on the types of signals it transmits to traders. The use of these signals solely represents the entire movement and behavior of the forex market. The forex market is comprised of several numbers of beginner traders and professionals with the normal trading generally ranges to more than trillion dollars each day. However, some traders might gain more profit yet, another party or of half of the population loses. The other half who loses might practically lack the skills thereby generating to a profit loss and might have the inability to provide themselves of accurate forex signals needed in this volatile market.

In addition, forex signals can be acquired by service providers catering to currency exchange signals. This service can be employed through a monthly subscription that is also paid every month. However, if this idea doesn't seem to fit your preference then you can also go by the use of software program. This does not call for any monthly obligation fees for you purchase it given a one time payment term.

Forex signals have been revolutionized by the advent of modern technology. Gone where the days of signal transmission through radio or phone as currency signals can now be done and can be easily transmitted through forex software that will work on your behalf and generate more profit even on your absence. This sound too good to be true yet, the upshot definitely is something worthy of divulging. With this, forex signals are indeed your path to easy money and gains.Tired of using Forex Signals with slow returns?

To understand how satellite radio works you must first understand how analog radio works. Analog radio works by broadcasting the radio frequency to local transmitters and then on to the listener. Satellite radio works similarly but instead of using stationary transmitters with limited range to broadcast their media to the people, they use mobile Satellites.

Satellites are equipment that orbit the earth and can pick up and transmit signals globally instead of just in a limited area. In the satellite radio category a satellite bounces the transmitted radio frequency off of the satellite and out to the millions of satellite radio listeners around the world. This has increased the satellite radio industry and has made satellite radio a staple media avenue in our everyday lives. Does this help you to understand the question of how does satellite radio work?

A user such as myself or you, who is interested in satellite radio purchases a satellite radio device whether it be stationary or portable, we purchase the desired satellite radio service from whichever service provider offers us the best variety of programming. Once the subscription to this service is established, the device is programmed into a database of devices that are allowed to receive specific radio transmissions from specific satellites. This entry into the database then sends a signal to the device to decrypt satellite frequencies, providing the user with audible satellite radio reception. This explains the question of how does satellite radio work?

Many service providers may use different marketing gimmicks to gain a customer base, claiming to have better coverage or what not. When it comes down to it, The only difference which could be considered is the limitations put on the satellite radio by the databases and what programs and filters any individual service provider may be using to limit the access their customers have to the satellite radio feed. Service providers may offer special features, or special programming which is solely controlled by their databases and the servers they use to transmit the satellite radio feed. You rarely hear of a service provider explaining to the customer the answer to the question of how does satellite radio work?

If a user fails to pay for their subscription to the satellite radio feed, just as with any utility nowadays, the service provider may then send a signal to the device, removing its rights to decrypt satellite radio transmissions. Many technologies in the past, prior to the radio technology have used satellites to widen the spectrum of their services, such as telecommunications such as cell phones. The principal of each service is relatively the same in the fact that a person uses a device such as a satellite radio, or cell phone, to request a transmission through a service provider's database. If the subscription is paid for the transmission is allowed from the satellite to the user giving us satellite capable radio devices.

It was initially popularized by truck drivers who used it to communicate traffic problems and alert others to speed traps. Drivers also found solace in the CB during long trips.

The low cost and easy-to-use design gave the CB its much-needed popularity push. Initially, the CB was popular in the United States, but later the British, who began illegally operating them, imported the equipment. The UK government was forced to legalize CBs in 1981 while CBs gained popularity in

Australia during the 1970's.

The CB radio and its uses were always regulated by a governing agency in Australia. Restrictions on the equipment, like antenna height and the maximum output power, had a damaging effect on its popularity. Apart from this, there were illicit users who modified the equipment to interfere with signals sent out by licensed users. Despite these illegitimate developments, the CB always had a loyal and growing following.

CB Radios Today

The 20th century focused on many different technological advancements, including the CB radio. Even with the advent of mobile services and the Internet--if you feel the CB radio craze has died down, you are mistaken. To those living in remote areas, especially those without a telephone line, CB radios offer the best communication system. For truck drivers, CB radio is still the preferred mode of communication. They are also popular among hunters and farmers and, in rural areas, CB radio is popular as somewhat of a party line.

Commercial truck and cab drivers still use CBs for communicating among themselves. While channel 19 is used to send emergency signals, some parts of the United States have dedicated channels on specific routes.

Today, most users have moved to the UHF band because of the clear performance it offers. The popular services in vogue today include FRS, GMRS in the UH frequency band, and multi-use radio service in the VH frequency band. FRS and GMRS are the perfect choice for those who intend to communicate with others living in the vicinity, and the equipment used for this service are of higher quality and can be used within the city as well as in dense areas. http://www.computer-electronic-news.com http://www.eduation-tips-now.com ]]> http://www.artwoo.com/article/satellite-radio-companies http://www.artwoo.com/article/satellite-radio-companies#comments Mon, 04 Dec 2006 04:27:04 +0000 xm satellite radiosirius satellite radiosirrus radioxm radiosatellitesdigital audio radio servicerepeaters http://www.artwoo.com/article/satellite-radio-companies Digital Audio Radio Service. The companies that were initially given a license to broadcast on this spectrum were XM Satellite Radio and Sirius Satellite Radio. Currently, there are three satellite radio services broadcasting around the world: XM and Sirius in North America and WorldSpace in Europe, Asia and Africa.

The three satellite radio companies each have a different system for broadcasting their signals. This means that a customer would end up buying specific equipment depending on what company they subscribe to. There are three parts to a satellite radio system: the ground repeaters, the satellites and the radio receivers. The XM satellite radio has satellites that are geographically located above the equator at all times. To combat the issue of obstacles such as hills, bridges and buildings, the XM radio service has a network of repeaters. These are antennas that get the signal from the satellites and transmit it to the subscriber's radio. The Sirrus radio service is set up a little differently. The satellites are elliptical in structure and they orbit the Earth. Because these satellites are on a higher level, the signal is usually clear and there is no need to have quite as many repeaters.

The satellite radio programmers are able to choose what music or program to fill air time. Many use CD's or have musicians come in to perform live. This sound is transmitted via a digital format. The signal is encoded by the satellite and then sent to the repeater antennae. The repeater moves it along to the subscriber's radio which decodes the signal and plays the sound. Satellite radio also utilizes digital compression which is a method of reducing a set amount of information into a bandwidth using complex algorithms. If you are a subscriber, you will have to purchase the correct equipment to get the signal.

The amount of people who subscribe to satellite radio has grown due to the improvements made to the technology. The appeal of the radio station has always been the fact that the radio doesn't depend on advertising to pay the bills, therefore the programs available are commercial free.

While not having to endure the same regulations as applied by the FCC in regards to free radio, the broadcasters of satellite radio, like cable television, have more options available to them and are able to offer a wider variety of programming as a direct result.

Satellite radio is the cable television of the radio broadcasting world. People can buy a satellite radio subscription in much the same manner that they would subscribe to cable television. The subscription includes various types of radio broadcasting not otherwise available to the listener. These usually include more adult-oriented radio broadcasting since the FCC does not regulate the industry in the same manner that they do for the free radio airwaves.

Since people are paying for the privilege of listening, and satellite radio is a buyer's market, the wide selection of broadcast media that is available are regulated mostly by what the listeners want and what they are willing to pay for. While satellite radio may not be a viable alternative for everyone, it does offer more listening opportunities for those people who are willing to pay for it. Satellite radio subscriptions vary in cost, but all things being equal, the subscription fees are not at all unattractive when the broad spectrum of radio programming is compared to what limited choices are available without satellite radio.

There are also still some limitations in the availability of satellite radio. While these areas are in steady decline as satellite radio listeners increase in numbers, there are still voids in the market where it is not yet financially feasible to install satellite radio options. It is best to check for the availability of satellite radio before purchasing any satellite ready receivers.

Satellite radio receivers vary in all manner of shape, style and output range and are available to fit the needs of most any satellite radio listener. Deciding which one is best for any given use will require the purchaser to do a little research into satellite radio and what local options are available, then adjusted according to the personal preferences of the listener.

While the advent of Satellite radio technology is seen as a new path to freedom for some and a road to decline for others, the satellite radio of today looks like it is here to stay. If satellite radio is available in your area, it can be a worthy investment. Satellite radio really does offer many options not available to the regular radio listener.

With the availability of equipment and the benefits the service has to offer, it seems more and more people are choosing to use satellite radio. If you are wondering how satellite radio works, read on.

Satellite radio offers you commercial free radio. No more static, no more interrupted broadcasts; just hour after hour of uninterrupted music. And you won't lose your favorite radio station as you cross the state. But you will have to pay for all this convenience.

Your dependable traditional radio won't work for satellite radio, so you'll need to purchase a new radio and you will need to have it installed (unless you are purchase a portable system). The price of the new radio varies depending on the model you choose. You'll also need to pay an activation fee and a monthly fee.

Think of satellite radio as an extension of cable. For your monthly fee you'll get edgier and less censored programming, innovative programming, more channels, and specialty channels. As an added convenience, while you're listening to the music you'll see the name of the song and the artist name displayed which means no more confusion about whose song is playing.

Back in 1992 the FCC allocated the 2.3 GHz or S band for nationwide broadcasting of satellite based DARS. Four companies applied for licensing and two were granted licenses. The two that were granted licenses were Sirius and XM. Both already had satellites in orbit.

They operate by beaming their programming to their satellite, which then transmits the signal to the ground. Your satellite radio then picks up the channel you have selected to listen to.



For listeners that live in urban areas satellite signals can become interrupted, so the satellite providers also beam the signal to ground repeaters to ensure that doesn't happen.

Sirius was the first to offer commercial free programming on its music channels, but both Siruis and XM now have commercial free programming. Both are competitively priced. Currently, XM offers over 160 commercial free channels. Sirius has over 125 commercial free channels.

The special programming that Siruis and XM carry is the deciding factor of which service to choose for many people. Sirius carries NFL football games; XM carries college games. XM carries NASCAR races; Siruis has a Playboy channel. Sirius carries Howard Stern; XM carries Oprah.

Satellite radio is no longer the radio of the future. It's the radio of today, and is being chosen over traditional radio programming by more and more people every day.

When you have a Sirius satellite radio receiver you can listen to whatever you want wherever you go. There is a Sirius satellite receiver to meet the needs of everyone, whether you want one for your home, your office, your car, your boat, or your RV. There's a lot of buzz right now about satellite radio. With the introduction of XM and Sirius the new satellite radio broadcasts will give local broadcast radio a run for their money. If you've been thinking about buying an XM or Sirius Radio, now might be a good time to make that purchase as the cost of these radios is now at the lowest point ever. The top 2 contenders are Sirius and XM Radio.

Both providers offer high quality, digital programming with over 100 channels to listen to so you can never run out of something good on the radio. As mentioned above, cable started to address those issues, but it's been the advent of satellite technology that has really brought clear digital entertainment to the masses no matter where they live in the US. Satellite radio and TV both broadcast their signal in digital formats rather than analog.

Sirius charges more because they claim to use technology that improves the digital sound even more than XM and they also have given more attention to customer service to address issues that may arrive after the sale. Satellite radio broadcasts are made in digital format, so they are much higher quality than land-based radio. Satellite radio or is a digital and is able to receive signals from just about anywhere which of course has a broader range than normal radio.

With satellite radio you pay a certain subscription fee every month (around $15 or so) to get around 100 music channels broadcast by satellite. All programs are transmitted a satellite and then is beamed to the ground where the satellite radio picks up the signal. None of the channels are pre-recorded and all of them are LIVE stream videos from the fastest servers in their network.

There are several different kinds of music genres. For instance, rock has channels devoted to hard rock, early rock, soft rock, heavy metal, and many more. When using a satellite radio you can have your favorite music broadcasted right into your home or car, with crystal clear digital sound. Some system have a slight delay in the broadcast so if you enter a tunnel you do not loose the signal.

Satellite radios come in many forms including at-home devices and portable players much like Apple's ipod. People that have taken a liking to satellite radio are flocking to their local electronics store looking for a portable satellite radio. Like a full size or car satellite radio a portable satellite radio has all the required equipment to decode the encrypted signal broadcasted by a satellite.

Subscribers to satellite radio will be required to pay a monthly fee. It is subscription based, meaning that you pay a monthly fee for the service.

Subscribers usually have to pay a monthly fee of approximately $9. When purchasing a satellite radio there is usually a small monthly fee, but this will introduce you to a new world of commercial free radio.

One of the biggest benefits of Internet radio is that the data is transmitted over the Internet making it possible to listen to radio stations from all over the world. Expatriates find this particularly beneficial.

Similarly, though, it is also cheaper to produce music over the Internet and this means that smaller stations with a smaller fan base than mainstream radio requires are able to run their own radio station. This makes it perfect for those who like particular genres of music to find exactly what they are looking for.

Internet Talk Radio was the first ever Internet radio service and was established in 1993 and in 1995 the first radio service published only on the Internet was introduced -- Radio HK. Since then the number of stations opening on the Internet has increased dramatically. Peercasting, or P2P technology, makes it even easier to start an Internet radio station so it is likely that there will be even more stations in the near future.

Internet radio is perfect for people in small towns that are monopolized by only two or three radio stations and are forced to listen to one playlist of songs over and over. With internet radio the possibility of gaining access to music that a person likes is greatly increased.

Whether you are looking for radio broadcasts from countries miles away or you want to listen to one particular genre of music you can be virtually assured of finding a station that caters to your needs. You can even find chat stations that deal with one particular topic. The quality of sound and the quality of the programs distributed are both excellent. If you haven't tried Internet Radio before, you should try it now. About The Author: Lavinia Snider is the editor of internet Radio Guide. Find out everything about internet radio.

With conventional radio, land-based stations broadcast their signals to your boom box, computer, or car radio via the earth's airwaves. With satellite radio however, providers transmit encrypted signals to satellites they launched in outer space; these satellites in turn beam the signals to customers' listening devices. But you can't use just any radio; you need a special receiver (which is available at electronics retailers) and a satellite radio set. You can also listen to satellite radio broadcasts in your car since many new cars rolling of the assembly lines have satellite-ready equipment already installed. All you would need to do is pay for your monthly subscription.

In the United States, service is offered by XM Satellite Radio and Sirius Satellite Radio. Sirius, a company based in New York City, has over 125 channels from which to choose, 67 of them dedicated to commercial-free music and the rest to various other content. XM, on the other hand, offers more than 160 channels, which offer content that is as diverse as that which Sirius extends to its customers. The services are available coast-to-coast, so geographical availability of programs is not an issue. A customer in Los Angeles, for example, can listen to the same talk show that another customer in say, Boston, is listening to at the same time, and with no degradation in audio quality. Remember that satellite radio also means digital radio -- sound is crystal-clear. There's none of the static or hissing you would sometimes hear on FM or AM radio. Non-US residents can also take advantage of the benefits of satellite radio; XM and Sirius offer their services in Canada, while WorldSpace broadcasts its service across Asia, Africa, Europe, and the Middle East. Australia has several providers of its own also.

Factors that attract people to sign up for satellite radio subscriptions are numerous. For one thing, there's the pleasure of listening to commercial-free music. Since the providers make their money from subscriptions, there is still no pressing need for advertising revenue. Another attractive feature that this service offers is that information about the song being played at the moment is displayed on your radio set -- a small convenience for those people who have to know about who is singing what song right-now. The fact that satellite radio programming is completely uncensored at the moment is also a draw for many people. Noteworthy personalities, such as shock jock Howard Stern (who was kicked out of network radio programming) has made satellite radio his new broadcasting home. Whether you want to listen to hip-hop music, stand-up comedy shows, or news programs, satellite radio offers them -- all completely uncensored.

Because Sirius, XM, and other providers are the ones who set the channel selections, some people might find it a bit inconvenient that they won't be able to listen to their local radio stations and get information on local goings-on. However, Sirius and XM do provide traffic and weather data for major cities, so that should be a bit of a relief for city residents. And if you think about it, not getting access to one local radio station wouldn't seem to be such a bad deal if you compare it to the ability to listen to hundreds of channels of commercial-free music and unregulated non-regulated shows.

Sirius and XM plan to add even more features and functions to offer to their subscribers. Sirius, in particular, is readying the launch of a Windows Media Video 9 service and the company plans to offer several channels dedicated to children. That's one more thing to keep the kids occupied and not distract their parents on long road trips. XM plans to release a similar video service. The two companies are anticipating that this will add to the number of their subscribers -- Sirius has over one million, trailing after XM which has more than three million.

If you're an avid radio listener and you're finding yourself becoming fed up with the constant barrage of commercials on regular music stations or if you're looking for more no-holds-barred commentaries or radio talk shows, you probably wouldn't mind forking over the $12.95 monthly subscription for satellite radio service charged by Sirius and XM. And with the increases that the two companies see in their subscriber numbers, it's evident that a lot of people feel the same way.

The objective of a radar detector is to protect the motorist from getting a speeding ticket from the officer who is using a radar gun.

Radar detectors were introduced in the early 1970's. The term radar detector originated from technologies that were used earlier to detect speed.

Now the question arises, andquot;What is radar?andquot; Radar is a system used to measure the speed and location of any object. This system consists of two important parts - a transmitter and a receiver. The radio transmitter causes voltage fluctuation by oscillating an electric current at a predefined frequency. This oscillation of the electric field generates electromagnetic energy. This electromagnetic energy propagates in the air as electromagnetic waves. A transmitter consists of an amplifier and an antenna. While the former increases the power of electromagnetic energy, the latter transits it into the air.

The basic function of radar is to determine its distance from the destined object. For this function, the radar device emits concerted radio waves to observe any echo. If any object comes in the way of the radio waves, then it can be easily detected by radar with the help of electromagnetic energy. Radio waves constantly travel in the air at the speed of light. The distance of the object from the radar is determined by observing the time taken by the radio waves to return.

For measuring the actual speed of any object, radar can be used with a fact called Doppler shift. When any moving object passes in front of the radar, its echo will reflect the signals of the radar. The time taken by the radio signals to return after striking the object, and the frequency with which they travel, gives the actual speed of that object. If an object is coming towards the radar, then the signals will come back in a shorter period of time. It will increase the frequency and tells the actual time in which an object will cross the radar. This process depends on how fast the frequency will change. Traffic police use radar in the form of a radar gun, which is either hand-held or vehicle mounted, to detect speeding vehicles.

A basic radar detector detects police radar with just a simple radio receiver. In contrast, detectors that are more sophisticated comprise of a basic receiver along with a radio transmitter. A jamming signal is produced via this transmitter. It blends the signal of the police radar gun with extra radio noise. Due to this, a perplexed echo signal is received by the police radar gun, and the exact speed-reading cannot be taken.

Light-sensitive panels are being used in modern detectors which detect the beams from police laser guns. Lidar is difficult to avoid due to its concentrated beam, so it is quite possible that by the time the detector is able to detect it, the vehicle is in the beam's sight already. For that, speeders also use a laser jammer. It works much like a radar jammer.

In conclusion, there are several systems available to detect radar, but none of these systems is a sure shot way to get protected against speed detectors. However, one thing that can be done to avoid speeding tickets is to 'slow down'. Article by Stefan Rockhaus.

Before satellite television became popular in the market during the early 1990's, satellite dishes were costly metal equipments that occupy a large space of the home yard. In early times, those die hard TV fanatics would endure all these hassles and avail these expensive equipments just to set up their own dish. Satellite TV was far more complex to obtain than regular broadcast and cable TV in the earlier days.

Nowadays, most household in the US have compact satellite dishes rested on their rooftops. We could also notice that most of the rustic areas that can't be reached by cable companies have satellite dishes. Many satellite TV companies are enticing more customers every single day with movies, game events, and daily news from all over the world which guarantees high quality picture and audio.

Satellite TV provides a lot of solutions to cable and regular broadcast TV dilemmas. With the continuous development of satellite TV, it is becoming the popular option of numerous TV viewers.

Satellite TV is not like the usual TV broadcast. It's using a wireless system to hand over TV programming straight to a consumer's home. Both satellite and broadcast stations transport programming through radio signal.

Broadcast stations utilize a strong antenna to transport radio waves into the surrounding field. Consumers can obtain the signal through a smaller antenna. The primary boundary of TV broadcast is range. Radio signals that are employed for TV broadcast beam a straight line from the broadcast antenna. To be able to pick up this signal, you must be in the scope of the beamed signal of the antenna. Little obstructions such as trees or low buildings are fine but huge obstructions such as land mass will mirror the radio waves.

If the land mass is flat then you would receive the TV broadcast even if its miles far from the source. But due to the shape of the land mass of the Earth the signal breaks out. Another problem that occurs with TV broadcast is it the signal becomes distorted. If you want to have a clear signal like what you can have with cable tv then you must be situated pretty near the broadcast antenna and there must not be any obstructions in sight.

What did satellite TV came up with to solve these problems about range and distortion? The problem is solved through transporting broadcast signals coming from satellites revolving around the planet. Because the satellites are high above the sky, then a lot of viewers are in the scope of the signal. Satellite TV systems transport and picks up radio signals with the use of specialized antennas known as satellite dishes.

When you avail of a satellite TV, you are on your way to viewing TV programs with much clarity and gives out 100% digital-quality broadcast and audio on each channel. Don't be fooled by so called digital cables because they still broadcast analog channels.

It provides crystal-clear digital sound around the globe without commercials or unwanted pauses. It offers a vast array of listening options, from every type of music genre to every type of sports coverage and news programming. It's little wonder the satellite radio service is number one in the United States with over two million satisfied customers.

The numbers are remarkable. Those two million listeners get the pleasure of choosing from 68 commercial-free music channels. These channels include any genre from country, rap, hip hop, metal, bluegrass, reggae, rockabilly, to classical. On top of these, 33 channels are available for the latest information in news and sports, along with the leading talk shows and entertainment programs. Even more impressive are the 21 channels that provide continuous and immediate weather and traffic for the major metropolitan areas in the country.

XM Radio is not just produced on its airwaves, though. There are its award-winning receivers and reception devices that you need to secure the satellite radio signals. But there's no need to be worried that you're going to have to go out and replace your home stereo equipment. You can effortlessly add satellite radio service to your existing audio and home theater system.

Or you can purchase the latest new XM Radio equipment. This equipment is some of the smallest and lightest satellite receivers and antennae in the field, so it is a sound investment no matter what. Your XM equipment allows you to listen to regular AM and FM radio terrestrial broadcasts if you wish, as well as your CDs and cassettes.

Other features included in the receivers are a display and memory so that the device shows the channel name, artist name, and song title for every song you listen to. No more reliance on a DJ to tell you what you are listening to. For you auto-based audiophiles, the satellite radio service is available in more than 100 new cars in the 2006 models. You can pick up the Delphi XM Roady 2, the Delphi XM Roady, or the XMCommander for your listening pleasure in your car.

No more spending the majority of my driving time switching between stations, with a satellite radio, I can choose exactly what I want, when I want it.

The units that receive the satellite signal in the home are rather limited but the ones for the car, well that's another story. Here are some tips for selecting satellite radio for your car.

Buying an after market radio that has a satellite receiver built in is the easiest way to add satellite radio to your car in my opinion. My husband went the route of adding a simple satellite receiver to his existing radio. The drawback was, not only did it take awhile to install it came out messy.

Aftermarket radios, can be purchased to bring in just the satellite signal, AM/FM radio stations, CD or it can come, as I selected, with all three built in.

When traveling on a trip, I found this was the most convenient as I could keep up with local happenings with my regular radio but when I wanted crystal clear tunes, I had my CD or Satellite radio to choose from.

One of the things that people mistakenly think about satellite radio is that all you have to buy is the monthly subscription to enjoy commercial free satellite radio. The fact is you do have to consider the cost of your subscription AND the cost of your satellite radio AND the cost of a professional installation. In most cases this amount can easily add up to a few hundred dollars.

By far the least expensive way to get started with satellite radio is to add one of those add on radios, like my husband bought. You can buy one for about $100 dollars and although the installation will take some time, it sis nothing that most people can't do themselves.

Some don't require installation at all, all you need is something called the FM modulator to be located near the FM radio in your car, IT will do the rest. This is a great solution if you just want to try satellite radio or if you change cars often.

So you can get started for as little as $100 dollars but for a mid to top of the line radio, expect to pay between $300 and $500 plus installation, and worth every penny!

And everyone tries to justify that cell phones have become a necessary tool of communication and that he or she needs to use them. Well, let's put it straight. Historically, necessity has always invented solutions and equipments that satisfied them. It never was the other way round. Even the cell phones, in their present or generic forms, when there already existed a huge vacuum for them. So, I will take the position with the famous saying, 'you can't hold an idea whose time has come.'

Cell Phone: How Does It Work and How It Helps You

Cell phones work like two way radios which receive and transmit voice which are in the form of radio frequency waves. When you speak into a cell phone, it coverts your voice into these electromagnetic radio waves which can travel in air till they meet their destination. The designated receiver is the called phone, which picks up the RF signals and converts back to understandable human speech. If signals have to travel long distances, like in a long distance call, the signals are picked up by a combination of base stations and satellites which receive and retransmit signals back and forth. For simplicity, you can think of satellites and base stations as a series of mirrors that redirect signals between two ends.

Two Rival Technologies for Cell Phones

In this day, there are two types of cell phones which are popular. Although, it won't mean a bit different to you and I, they use two 'rival' technologies. The first and the more popular one is called GSM, an acronym for Global System for Mobile phones. The third generation of this is the reigning technology which moved cell phones from ordinary phones to being a 'what not.' You have video and still cameras, MP3 players, internet browsers, make shift computers, fax machines etc to name a few.

The next, but a recent entrant is CDMA (Code Division Multiplication Access) technology. Although new, this is now way inferior to its competitor GSM. Anyone using CDMA can never tell whether it is CDMA unless he opens it or someone else tells him. Well, why open? GSM cell phones use replaceable electronic chips called SIM cards which contain many data about you and cell phone to locate you and preferences like billing etc. In CDMA technology, these data are encoded into the irreplaceable microchips.

Can you live without cell phones? You will have to live in deep woods to try it out where there is no connectivity at all. But did you know there is just one number that can be dialed without connectivity? Fine, you can't exactly live without this emergency number: 112 (varies).

These parts communicate trough light beams, lasers, radio signals and infrared. However, the problem with this devices and technologies is often the connection between each component. Thus, most systems are not used to their full extent due to complexities.

To simplify things, a solution was created to streamline the process of connections- bluetooth.

Bluetooth is wireless and automatic and offers users with varieties of excellent features that has recreated the art of connection. It has revolutionized the standard method of connecting things that virtually anything can be connected on a single system. From computers to mobile phones and from keyboards to headphones by means of wireless, automatic and inexpensive connection.

Other than the bluetooth technology, there are other ways of connecting things. Take for example the infrared or IR. It allows low frequency light waves which the eye can no longer interpret to transmit signals to another component. The technology is easy to create and cost of incorporating the IR device into a system is in barest minimum. Yet it has limited operations that seldom obstructs the process of connection.

Infrared technology is one to one process. Due to this limitation, you may only send signals from one component to another, like the case of the television set and the remote control. The same is true between laptops and desktops. You may only transmit signals between the two but not with another separate system, say a PDA through simultaneous actions.

It also works only on the line of sight principle wherein one has to point the infrared device directly to the host system to achieve a desirable result.

In spite of the fact that these two natures of infrared technology are obstacles to acquiring results, these same qualities have worked in advantage to connection. Because infrared devices need to be lined up directly on opposing locations, too little interference occurs between transmitters and receivers. The one to one principle on the other hand is designed to transmit signals only to the original recipient. Given that there are varieties of infrared recipients in a location, the intended recipient alone will receive the signal coming from a transmitter.

However, technology was not contented with what infrared offers. They resolved these limitations through creating the bluetooth solution.

Bluetooth technology works by transmitting signals via low frequency radio signals. The path of communication is approximately working on 2.45 gigahertz. The same frequency band is utilized in ISM devices.

The design of the technology was such that it has created a new system that does not interfere with the other devices that make use of the same frequency band (e.g. ISM). One way of doing this is the programming of the bluetooth technology to only transmit signals that has 1 milliwatt or less. Beyond this, other systems may be affected. By comparison, cell phones and other mobile devices send signals at a rate of 3 milliwatts and more.

The standard range of the bluetooth is around ten meters. This lessens the possibility that interference between device may occur. With this low transmission, it is still possible for the user to transmit bluetooth signals between obstructing walls.

Bluetooth in many ways have contributed much in connecting individual systems without being bothered by the bulk of the cables and wires.
