Individuals, of all different ages, enjoy meeting and communicating with other internet users. Despite the fact that individuals of all ages use the internet to socialize, there are certain groups of individuals that do more than others. Those groups of individuals include students, both high school students and college students. For that reason, it is only fitting that there should be a social networking website that has a focus on these particular individuals. That networking website is known as Facebook.

Facebook may not be as well known as other popular social networking websites, such as Yahoo! 360 or MySpace, but it is still popular. That popularity is mostly among high school students and college students, mostly because Facebook focuses on these individuals in particular. With Facebook, you are required to register for a specific network. That network can either include the high school or college which you attended or are currently attending. Once you have joined the website, you should easily be able to make contact with others who are in the same network.

The network in which you join can be considered an advantage of Facebook, as well as a disadvantage. See, Facebook does not work like most other social networking websites. Instead of being able to communicate with all site members, you are limited to contact with those that are in your particular network, the high school or college you that selected. The creators of Facebook state that this is for your own safety. Although it is safer for your profile and personal information to be viewed by a small number of individuals, you may not necessity want it to be that way.

Although a large amount of focus is placed on high school students and college students, Facebook has added another popular feature to their website. That feature is workplace networks. By joining a specific workplace network, you will be granted access to other community members who work for the same company as you. This feature is nice, especially since many companies have become large corporations or expanded across the country. You may be able to make contact and become friends with a long-distance coworker that you never knew you had.

Another aspect of Facebook that you may find inconvenient is their lack of available information, before you decide to become a community member. When viewing their online website, which can be found at www.facebook.com, it is hard to tell whether or not the site is free to use. Most online social networking sites will make this known right upfront, but Facebook does not. Aside from the price, you should easily be able to obtain additional information on Facebook, before making the decision to become a member. This additional information may include how Facebook works, why you should become a member, how the invite process works, and general rules and restrictions that are in place.

If you are interested in joining the Facebook community, you should do what you should do with all other social networking websites, research. By taking the time to research and examine everything that Facebook has to offer, you should be able to decide whether or not this popular networking community is what you were looking for. There is a good chance that it will be, but if not, do not worry. There are literally an unlimited number of other social networking websites that you can join.

How you would like to meet and communicate with other internet users, especially ones that share the same views and beliefs as you do? If you would then you may want to think about joining a social networking website, if you havent already done so. When it comes to easily finding and communicating online with other internet users, social networking sites are, perhaps, the best way to go.

If you are interested in joining a social networking website, the first thing that you will need to do is find a network to join. You can easily find a number of networks by performing a standard internet search. For the best search results, you may want to search with the words social networking or social networking websites. In your search, it is likely that that you come up with a fairly large number of different networking sites. Popular sites that may be included in your search results may include, but will not be limited to, MySpace, Orkut, Yahoo! 360, FriendFinder, FriendWise, Facebook, and Classmates.

Once you have made the decision to join a particular social networking website, whether or not it is one of the ones mentioned above, you will need to need to register with the site. Even free networking communities require that you go through the registration process. Once you are registered, you should be able to start communicating with other community members. Before you start communicating, you may need to develop your online profile or profile page, depending on the networking site in question. Although it may seem easy enough to create a profile, there are many internet users who are unsure exactly what they should and should not include.

Perhaps, one of the most important things to include in your online website is your picture. While a personal picture is optional, it is ideal. Many internet users enjoy taking to someone that they can see in their minds, without a picture this is difficult. If you are looking to use social networking websites just to meet new friends you may not necessarily need to post a private picture, but you may need to if you are looking to find love online. When it comes to internet dating, many individuals will not even view an online profile if a picture is not included.

In addition to your photograph, you may want to include your name. Now, when it comes to your name, you need to be cautious. You are advised against giving your full name, especially if your profile or profile page contains a personal photograph of you. In addition to your name, you may want to put down your location. As with your name it is important to display caution. Your picture, your address, and your full name can be dangerous, especially if it falls into the wrong hands. As much as you would like to fill your social networking profiles with personal information, you are advised to think about your safety before anything else.

You may also want to include information on yourself. This information may include your hobbies, issues that are important to do, your likes, and your dislikes. With many social networking websites, including MySpace, you will find that there are preset profile fields for this information. In addition to preset questions or categories on your likes and dislikes, you may also find additional information, including fun questionnaires. Many social networking websites will ask that you describe your favorite color, your goals in life, your most embarrassing moment, and so on. As with your other personal information, it is important to stay as vague and possible and not use any full names, especially real ones.

By keeping the above mentioned points in mind, you should not only be able to create an online social networking profile that is filled with valuable information, but you can do so while staying safe at the same time. Your safety on the internet is in your hands, that is why it is important to think about safety, as well as internet popularity.

One of the great advantages of satellite radio is the fact that the programs are not interrupted by commercials. This is because the providers income comes from listeners and not from advertisers. Satellite radio services offer around 70 programs of commercial fee music channels each and you have a great variety of choices, from mainstream rock, hip-hop and dance music to folk music, opera, blues and many more.
Another great thing about satellite radio is the absence of static. You can be driving from the West Coast to the East Coast in the United States of America and you will not get any static at all on the way. The satellite radio signal is digital, which means that you will get crystal-clear sound wherever you go.

Satellite radio tuners receive, along with the actual radio programs, an influx of metadata that consists of information regarding song title, artist, radio program and radio channel. This means that your satellite radio receiver will display all the necessary information about what you are listening to. For instance, if you hear a great song and you want to know which artist sings it, you just look at the receivers display.
All satellite radio programs are uncensored. This is one of the reasons why artists like Howard Stern chose to move their shows on satellite radio. You can also listen to your favorite hip-hop songs without the interruption of those annoying beep sounds.
Satellite radio programs also offer information about local traffic and weather conditions. The information is very detailed especially for those who live in big cities. If there is a major national calamity and other terrestrial radio stations will not work, you can always count on getting accurate information from satellite radio program. You can also listen to satellite radio online on your computer.

If you still are not convinced on why you should pay money for something that you can get for free, think about how much time you have wasted listening to commercials and all kinds of other boring stuff on terrestrial radio programs. Traditional radio is not free, despite the popular belief. It is time-consuming and irritating because you have to listen to five minutes or more of commercials so that you can finally hear a song you like. The satellite radio subscriptions are very affordable and, for around 13 dollars per month, you get exactly the programs you want, which you can listen to wherever you are, at the best sound quality.

Satellite radio is great for you especially if you travel a lot. If you are traveling across the United States of America, for example, you can listen to the channel or channels you want during your whole trip, without losing signal or getting static. If you have a traditional radio, you will have to keep changing channels every hundred miles, but if you are using satellite radio you do not have to do that because the geographically availability of programs is not a problem. Satellite radio subscribers will soon get the chance to watch video programs as well. Both Sirius and XM services have announced their intention of introducing in the near future a variety of video satellite channels that will have some of the great advantages that are currently available to satellite radio: commercial free programs, great quality of sound and vast geographical availability.

The idea of Americas biggest two satellite-radio joining forces has been up in the air for almost four years. Although XM had a years start, Sirius came back on the market, eventually with both companies sharing the market in half. So, whats to choose? XM or Sirius?
First things first. XM and Sirius are based on the same principle, each of them providing music, news, sports, etc. on their channels, but, every service has its ups and downs so we will try to discuss it in this present article. A careful analysis shows that XM Satellite Radio provides a total of 136 streams, where two are premium channels (Playboy and High Voltage), twenty-one are traffic and weather based channels and nine are sport-dedicated ones. On the other hand, Sirius offers a total of 119 streams, the premium streams not being available. Lets take a closer look now on two music and news – of the categories that the two major satellites are battling.

Music streams comparison

The number of music streams that both services offer is pretty much the same: 65 on Sirius and 68 on XM Satellite Radio but the difference is not in the number, but in the music genres that the radios offer.

Music Decades

XM is the absolute champion in providing the music by decades because you can listen to the 40s music, service not available on Sirius. Still, you can listen to the 90s hits together with the current hits on Sirius Satellite Radio, which is an interesting feature.

Music Country

Ride em cowboy!. Even if youre not a cowboy, you can listen to country-related songs on both Satellites. Classic country or country hits are to be heard as well as alternative country or country mixes, the last two features being available only on Sirius Satellite Radio. Regarding the number of streams that both Satellites offer, XM offers a total of five streams and Sirius offers four, the champion in this category being XM due to the quality and the quantity of music being played.

Music Rock

If you are looking for sex, drogs, and rock and roll, Sirius and XM Satellite Radios can only offer you rock and roll, on a number of 14 streams on XM and 15 streams on Sirius. The rock subgenres are to be found in a large number on the stations, overall each service being very strong in this category.

Music – Dance and Latin

If you want to boogie, you can do that on both Satellites, listening to one of the six streams provided by Sirius or four streams provided by XM. Be careful though, because you can become a clubber maniac! And if youre strong enough, the Latin pop stream, Mexicana and tropical music streams can really drive you crazy. XM Satellite Radio as well as Sirius Satellite Radio offer three streams.

Music Other genres

Regarding other genres, both satellites really look up to their prestige, offering hours of hours of music, from Classical to Jazz, even Urban (Sirius feature). Both stations offer high quality tunes, making it worth all the money.

News Streams Comparison

Lets skip to another interesting topic, news. CNN, FOX, CNBC, Bloomberg, MSNBC and many more news stations are being offered for listening in different languages. The number of streams is again near-by, XM offering a number of 11 news streams, not like Sirius, which offers 13.

Bottom line

Its pretty hard to say which station is better, XM and Sirius being tied musically but in news and sports, Sirius holding the edge. To make a little joke, if you are a fan of Stern go with Sirius, if you like Q&A go XM. Anyway, its hard to say which one is better, but, what can I say is that both Satellites are worth paying for.

XM Satellite Radio Inc. is one of the major players in the satellite radio industry, with over 2 million subscribers and spreading all over the American territory. XM Satellite Radio Inc. deliver over 120 channels of radio to an ever expanding customer number. Here are some of the characteristics of XM Radio:
Corporate headquarters: Washington, D.C.
Date of launch: November 12, 2001
Satellites in service: 3
Available satellite radio channels:150
Monthly subscription cost:$12.95

XM Satellite Radio Inc. is the owner of one of the 2 FCC approved licenses for delivering digital radio in the United States. Since it only shares the field of Satellite Digital Audio Radio Services (SDARS) with Sirius Radio, XM Satellite Radio Inc. has plenty of room to develop and expand. 2001 was the year when XM Satellite Radio Inc. began broadcasting progress was slow at first, but soon after satellite radio began skyrocketing as a social and economical phenomenon. Since it was the first national digital satellite radio service provider, XM Satellite Radio Inc. captured an important share of the market and started offering music programs and other types of shows and channels like talk shows, sports, comedy, science and news. XM Satellite Radio Inc. owns the most impressive digital radio equipment and facilities, boasting over 82 end to end broadcasting studios. The digital radio used by XM Satellite Radio Inc. is encoded using the complex CT-aacPlus technology which is broadcast in 128kb/sec format very close to CD quality. The signal produced by using this technology makes the transmission much clearer and more accurate than any analog radio provider could ever offer. There are no noise disturbances that were often present with FM and AM broadcasts and the transmission is crystal clear. The fact that the signal is received in digital form solves many noise disturbance problems and the output is close in fidelity to the original track.

The XM Satellite Radio Rock and Roll satellites

XM Satellite Radio uses two of the most potent commercial satellites, which are constantly orbiting the Earth at a height of 22 300 miles. The two Boeing HS-702 satellites have some inspired names – “Rock” and “Roll”. The first of the two satellites, Rock, was launched in orbit on March 18, 2001 and is currently positioned at 85 degrees West Longitude. It services the western half of the United States and complements the range and area of coverage of its younger brother Roll. Roll was launched on May 8, 2001 and it currently positioned at 115 degrees West Longitude, and it services the eastern part of the United States. The combined coverage of the two satellites spreads beyond US borders and reaches areas like Canada or Mexico. This is an interesting feature of satellite radio, as it further points out the benefit of not having to switch radio stations during long trips or while moving over the border. For emergency purposes, the company has third redundant HS-702 satellite on the ground, ready to replace Rock or Roll if any of them fails. Both satellites use different transmission frequencies which prevents interference.

Using the XM radio transmission

The powerful broadcast signal used in satellite radio means that you only need a small receiver in order to be able to listen to digital radio. These small omni-directional antennas are similar to GPS devices and do not require mechanical pointing in order to receive the signal. Some of the new features of satellite radio refer to the extended broadcast information abilities. XM offers information about the broadcast type, and includes the song title, artist, and genre of music. As a recent improvement, XM radio also started broadcasting weather related news and traffic statuses on their programs. In order to use the XM Radio programming you need a XM Radio receiver, an antenna and a subscription to the XM services. Different music equipment producers have teamed up with XM Radio in order to allow adding XM broadcasting to their already existing devices. Some vehicle manufacturers are also offering XM Radio as a factory installed option.

Urban rap and hip hop, both modern and from the 80s.
Jazz & Blues 6 channels altogether out of which four are commercial free
Dance techno and trance music rules here, but you also get some disco music
Latin 5 commercial free channels of Latin, Spanish and Mexican hits.
International Music 5 channels of music from around the world. You might find these five channels a welcomed break from all the music you are used to. Fresh music from around the world is presented daily.
Classical classical music from both famous and less renown classical musicians. You get the XM Pops, XM Classics, Vox and Fine Tuning. As you would expect, all 4 channels are commercial free.
Kids – Radio Disney and XM for Kids. Excellent programs that will keep your kid busy and happy for a long time.
News you will get Fox News, CNN Headline News plus other TV related news channels. They feature XM commercials.
Sports you will get channels like ESPN Radio, ESPN News, Fox Sports Radio, Sporting News, NASCAR Radio. These channels cover most of the important sporting events in the United States but you can also get international sports news here.
Comedy both family oriented comedy stiles and uncensored comedy bits. These channels are commercial free, which is really enjoyable.
Talk & Variety there are different talk channels and shows that are really engaging, such as E! Entertainment Radio, ABC News and Talk, Buzz XM, Ask channel, The Power and Family Talk. However, these channels have plenty of commercial time which is a bit of a disappointment from a paid subscription service.
Variation and content

These are the things both XM Radio and Sirius are after. With over 100 channels, each provider is able to identify and target all the important age and social groups in the United States. When it comes to music, there are extremely specialized channels on XM Radio, so the consumer knows exactly what kind of music they will run into on that particular channel. The kids channels are pretty good and the sports channels are also ok. If you like to get your news TV style, XM Radios choice of channels is also interesting. The fact that commercials are present is not that bothering, as they are only allowed to play 6 minutes of commercials per hour. However, some of the music channels are kept 100% commercial free, which is good news for music fans who do not want their audition to be interrupted by intrusive commercials.

Satellite radio is often considered one of the biggest improvements in broadcasting since the introduction of the FM band. Satellite radio is also called subscription radio or pay-radio because it is only available trough subscription to one of the satellite radio providing companies. Satellite radio follows a concept similar to cable television by providing a very wide range of programs which are not available in the traditional FM or AM format for a fee.

Satellite radio uses satellites to deliver radio programs to subscribers. The radio signal is broadcasted from Earth based stations to communicational satellites, which then redirect the signal to satellite radio receivers. The radio signal is broadcasted by communication satellites to a much larger area than traditional terrestrial radio antennas. For example, satellite radio is available al across the continental area of the United States. Satellite radio is available now in most parts of the world trough services provided by companies like WorldSpace (in Europe, Asia and Africa), Sirius and XM Radio (in North America). The radio signal you receive using satellite radio is digital, which means that it is always clear and static-free, which is one of the great advantages of satellite radio. Another great thing about satellite radio is that it is almost completely commercial-free.

To begin listening to satellite radio you will need the actual satellite radio (also known as tuner or receiver), a satellite radio antenna (which is often incorporated in the satellite radio) and a subscription to the service you choose. There are several types of satellite radio from which you can choose. One of them is the dedicated car or home radio, which play trough your car or home stereo. A second option is the plug-and-play radio, which can be used in your car, as well as in your home by paying a single subscription. Your third option is the portable radio, which has rechargeable battery, a built-in antenna and you can listen to it wherever you go using headphones. The radio signals offered by different satellite radio companies are proprietary, which means that you will need different hardware for receiving, decoding and playback, depending on your subscription. Each satellite radio receiver has its own serial number called Radio ID. When you get your subscription, you will also get an activation code for your receiver. Besides the actual radio programs, satellite radio transmits metadata that contains the name of the artist, the title of the song or program, as well as the name of the channel. This makes it easier for you to decide which channel to listen to and which program to choose.

Satellite radio services provide the subscriber with more than 100 programs that vary in content from rock and jazz to rap and classical music. But satellite radios utility reaches far beyond listening to your favorite music without the interruption of those annoying commercials. Satellite radio also offers exclusive sports programs, cultural and educational shows, news and talk-shows. Some of the celebrities that have moved their shows from free radio to satellite radio include Howard Stern, Opie and Anthony, Bob Edwards and Martha Stewart. Unlike terrestrial radio, satellite radio is not affected by bad weather or even calamities.

At first, many people wondered why they should pay for radio if they can get it free. However, satellite radio attracts more and more people every year due to its great advantages: no commercials, extensive reach, theme programs and exceptional quality of sound.

Any song you hear on satellite radio stars as a recording in a specific format on different recording mediums. IN most cases, the recording quality has to be maintained fairly high, usually around 384kb/s, while also being reasonably small enough to be transported on CDs and DVDs. The music tracks used in satellite radio are cataloged using a similar system to the MP3 cataloging criteria, the ID3 tags. The choice for the music tracks that will be played is made by each channel individually. The DJ selecting the tracks usually chooses about 20-30 minutes worth of music. The DJ has to listen to the tracks to make sure they are in proper condition and then simply lets the computer decode the original file. The same thing is repeated once the initial 20-30 minutes are exhausted and the music playing cycle repeats itself.

Sound encoding in satellite radio

Encoding is one of the key elements of digital radio. Each channel is handled by a different encoder. The encoder basically takes the analog file and turns it into a digital one. The digitalization process is made in real time and the music files are transformed into 1’s and 0’s. This process is carried out by powerful computers that analyze sound waves and frequency and break them into binary code. The encoding process is carried out at 128kb/s, 44.1Kh which is actually CD quality. After the song is encoded, it is transmitted to a multiplexer where other channels are also present the multiplexer basically takes all the channels of the satellite radio provider and combines them into a single broadcast transmission. The data is then sent to a satellite modem device which modulates the data and sends it to the broadcasters satellites, using unique transmission frequencies.
What happens above the Earth
Here is where the satellites are located. They receive the transmission and transmit it to the receivers we have in our homes and cars. The satellites are located at 23,000 miles above us both Sirius and XM Radio use satellites located at this distance from the Earth. The satellites are located in geo-sync, which means that hey orbit above the location they are designated to service at all times. When the satellite receives the transmission encoded at 128kb/s, 44.1 khz it rebroadcasts it to the geographical area it covers. Both Sirius and XM Radio use satellites that cover certain areas of the United states mostly the East and West coasts. For example, one of XM Radios satellites covers the western part of USA, probably an area located roughly from Seattle to San Diego on the West and Minneapolis to Houston on the east. The increased sound quality is possible because the broadcasted data (music tracks, news, sports transmission) dont get sliced up too many times in the decoding process.

The antenna

The antenna connected to your satellite radio receiver picks up the transmission on L-Band. The recent technological advances have allowed digital radio broadcasters to create receivers small enough to fit mobile locations. In the early days of satellite radio, a large parabolic dish would have to be mounted on the car in order to receive signal. Also, before the more compact receivers were created, the early satellite radio receivers needed electronic movements that directed the dish towards the satellite line of sight. Modern flat panel receivers have eliminated all the problems of their predecessors and can be fitted almost anywhere without taking up too much space.
The receiver and the output
The receiver is the device that decodes the data, basically doing the exact opposite of what the encoding process was like. After receiving the signal from the antenna it amplifies it and converts it to usable sound. The car or home audio system is then able to play the selected satellite radio channel. The rest of the process is exactly like analog broadcasts would work, with an amplifier and speakers outputting the sound.

The entertainment industry is one of the most dynamic and attractive ones, and satellite radio has recently captured a large share of it. Audio entertainment products are highly popular today and there is a wide variety of choices when it comes to having good music in your car: regular CD players, car CD players with storage space or MP3 players. When it comes to radio however, there is an even bigger divide you can listen to or go with one of the new satellite radio offers. The popularity of satellite radio broadcasting has gone sky-high in the past years mostly because it has some exciting benefits that commercial FM/AM programming simply cannot offer. Analog radio stations are not able to broadcast the full range of sounds available through digital satellite radio and this has a noticeable impact on sound quality. Digital radio programs are broadcast through a satellite this means that users dont have to switch radio stations every time they get out of a certain geographical area, as the signal is countrywide. Traditional to FM and AM broadcasts have different forms of noise disturbances satellite radio eliminates this problem as the quality is very close to that of the original tracks it is playing.

Technology and content

Because satellite radio uses such high tech instruments (satellites, small portable receivers) many still perceive it as unapproachable and prefer to stick with traditional radio. Most young people, however, cant wait to get their hands on the latest in technological advancements, so satellite radio is perfect for this age group. The price you had to pay for satellite radio one or two years ago was a bit high for many who decide to enjoy traditional, commercial radio stations instead, as they are free. Today however, for a subscription of around $12 per month, you can receive dozens of excellent news, sports and music radio channels. And the best thing is that they are commercial free. In many ways, satellite radio became popular following the idea of DirecTV’s success the difference was made through superior broadcast quality, excellent geographical coverage and content. This is in fact the main issue satellite radio broadcasters and terrestrial radio stations are looking at high quality content is actually the most flexible field where subscribers or listeners can be won or lost. In order to get valuable radio content, many satellite radio offers were made to popular media topics. MLB broadcasts, for example, might be broadcast exclusively on satellite radio stations. Although this is still an assumption, chances are that more and more popular US topics will be exclusively available on different satellite radio programs, whether they are from Sirius, XM Radio or from some new broadcasters that will join the market.

It all comes down to what the consumer wants

And its true it does come to that. Some laughed at the idea of paying for radio for as long as we have known, radio programs were free. However, the satellite radio industry only followed in the footsteps of cable TV although all Americans can receive free programs with UHF and VHF antennas, over 80% are willing to pay monthly subscription fees. With $9.95/month for XM and $12.95/month for Sirius, accessibility to satellite radio broadcasts is high and anyone can afford to subscribe. And the truth is that satellite radios have proved, once again, that sometimes a consumer is ready to pay for something they used to get for free as long as the commercials are eliminated. In many cases, out of an hour of radio broadcasting, around 12-15 minutes are commercials people dont want such interruptions in their radio programs. Both Sirius and XM Radio knew this when they launched their paid subscription services and they were right, as each company has millions of subscribers today. The satellite radio craze got even larger when it met the auto manufacturing industry today almost all major manufacturers offer satellite radio receivers as standard or optional with each of their models.

The satellite radio industry is dominated by two major players – Sirius Satellite Radio and XM Satellite Radio. Both companies charge a monthly fee for their services, but service payment plans often change to attract more customers. For example, starting in 2005 Sirius offers a $500 fee that is valid for the lifetime of the equipment. Sirius offers 65 music channels, without any commercials and traffic and weather reports for most of the major US cities. On the other hand, some of XM Radios channels did contain some commercials, but in much smaller quantities than those found on terrestrial radio channels. Today, XM has 67 commercial-free music channels, 21 channels with detailed traffic and weather information, 39 channels of news, entertainment and sports and an amazing number of 23 play-by-play sports channels. XM Satellite Radio Inc. owns the most impressive digital radio equipment and facilities, boasting over 82 end to end broadcasting studios. Sirius Satellite Radio is located in the heart of New York City with a huge recording studio. Sirius Satellite Radio has an impressive library of over 2 million music tracks.

Sirius Satellite Radio

Sirius Satellite Radio is one of the two main providers of digital radio broadcasting in the United States and it shares this important market with XM Radio. While you would think that XM and Sirius are 100% rivals, you will be surprised to find out that both companies are working together on a joint program in order to develop a receiver for both of their broadcast frequencies. Sirius uses three geosynchronous satellites that pass over the United States territory at regular time intervals and transmit the data alternatively. The Sirius satellite network is also located in a position that offers better line of sight this means that transmission interruptions caused by trees, mountains or any other landscape form are less likely to happen. Sirius announced that the number of subscribers to their services goes beyond the 4 million count

XM Satellite Radio Inc

XM Satellite Radio Inc. began broadcasting in 2001 and has seen a continuous development ever since. The digital radio used by XM Satellite Radio Inc. is encoded using the CT-aacPlus technology which is broadcast in a 128kb/sec format that is high in fidelity and is similar to CD quality. XM Satellite Radio Inc uses two Boeing HS-702 satellites which are constantly orbiting the Earth at a height of 22 300 miles. IN order to minimize transmission ad reception loss, XM Satellite Radio installed terrestrial transmitters in most major cities in places where loss of signal is more likely to take place (tunnels, high building areas). XM radio claims to have an impressive number of over 6 million subscribers.

Working with the automobile industry

Both satellite radio providers saw a huge market in the car industry, so they began negotiating with al major car manufacturers to convince them to offer their services and equipment as standard or optional on the vehicles they produce. Some of the auto manufacturers that have either XM or Sirius satellite radio installed from the factory are: BMW, MINI, Rolls-Royce, Chrysler, Dodge, Mercedes-Benz, Jeep, Ford, Lincoln, Mercury, Volvo, Land Rover, Jaguar, Mazda ,GM, Cadillac, Buick, GMC, Vauxhall, Saab, Honda, Hyundai, Kia, Nissan, Infiniti, Porsche, Lexus, Scion and Audi to name just a few. Sirius has managed to get exclusivity from major car manufacturers such as Audi or VW2007 through 2012. IT was a major success for Sirius as Audi and VW previously also offered XM radio services and equipment on their vehicles. After conquering the vehicle industry both manufacturers tried to move the success of satellite radio into the homes of consumers by creating some trendy portable satellite radio receivers. XM satellite radio created the XM2go line of “walkman-like” receivers and Sirius developed a variety of portable devices, such as the Kenwood Portable Satellite Radio Tuner, Here2Anywhere and the Sirius S50. More attempts are being made for introducing satellite radio in the homes of conservative media consumers.
