There are two major companies that offer satellite radio in America: Sirius and XM.
XM was the first company that offered satellite radio. It has two satellites named Rock and Roll and it has its studios in Washington D.C. Sirius Radio has three satellites and has its studios in New York. As XM was first, it has 3,200,000 subscribers but Sirius brings competition with 1,100,0000 subscribers in the present time.
Satellite radio is by far the best radio ever, making the AM/FM radios look old and dying even. This new era of radio has a lot of advantages that will please you at the maximum.
As the income comes from the subscribers not from advertisements, there are no commercials, no one is saying what to buy, no one is promoting their channel and no one is interrupting you from listening to what you want, where you want.
There a lot of choices in want to listen to as both XM and Sirius have a big programming variety that includes music channels of world music(pop, rock, classical, rap, hip-hop, opera, country, western, jazz, dance, blues, Latin), weather, news, traffic, sports and entertainment channels. Local weather and traffic channels are available only for major cities in the U.S.A. provided by the two companies and every five minutes you can hear updates. The best thing in all channels is that they are uncensored. So, you can listen to uncensored stand-up comedy and hip-hop channels, at least for now.
The satellite radio has a very good sound quality, no static and no interference, a quality that may be compared with the one of a CD. The radio is based on a go/no-go system based on the strength of the signal. So, weak signal may cause dropouts.
You can easily get information about songs and artists right on you satellite radio receiver that can also help you select channels and categories. This makes it easier for you to choose the exact channel or song you want to hear. So, whenever you are wondering what song or channel you are listening to just read the information that the receiver shows.
Now you can get satellite radio wherever you like, eventough at first it was design only for car use. With the right equipment you can easily have radio, but it depends on you whether you subscribe at XM or Sirius. Unfortunately, you can’t use a satellite radio turner for both XM and Sirius. There are three types of turners depending on where you want to listen to satellite radio. The Plug-and-play turner can be used out-door wherever you like as long as you have a portable boombox that can receive the signal. There are turners especially made for using them in cars and the home satellite radio turners for using them at home.
Both companies want now to offer a video service. This is planned to happen in the second half of the year 2006 and will include at first two video programs designed for children. Satellite radios' prices start at about $75.A subscription costs 12.95 per month wherever you want to subscribe as both XM and Sirius radio charges the same. There a couple of discounts like you can get satellite radio for a year at $9.95/month or Sirius is offering a subscription for a lifetime at $500.

Sirius Radio Programming Choices
Sirius Satellite Radio has more than 150 channels available with the subscription that they provide. This includes 65 commercial-free music channels and 56 sports, news, talk, entertainment, local traffic and weather channels.
Music channels seem to be numberless, but unfortunately they aren’t even tough there are plenty of music stations that please every person no matter what gender of songs he or she likes. So, there are country music channels that include New Country, Classic Country, Alternative Country and Bluegrass.
For hip-hop lovers, Sirius satellite radio has 4 channels: Hip-Hop Nation, Shade 45, Wax and Back Spin and not to mention the other streams where you’re ears will be delighted with house, club mixes, electronic a, disco, R&B, reggae and not to forget rock(classic, alternative, mellow, metal, blues) music. For classical tastes, there are three channels: classical pops, chamber music and classical voices. But if you are a jazz type of person you can relax by turning the radio on one of the six-channels of non-stop jazz.
There a lot of music programs that are hosted by international and national artist like Eminem, David Johansen Steve Van Zant, the Rolling Stone’s producer who can be listen on the Underground Garage channel.
Sirius has a beautiful collection of uncensored comedy that is available to you. You only have to tune into Sirius’s stream Raw Dog where you can listen to George Carlin, Margaret Cho, Cheech and Chong, Eddie Murphy, and Chris Rock
In the sports area, Sirius Radio has a terrific collection of channels and only enumerating those takes a lot of time. But here is a sum-up: the NBA, the NFL and the NHL. And besides this, Sirius wants to bring to you tournaments of men’s basketball games, the lineup of 27 college hoops programs and the Division I Men’s Basketball Championship and for the ones who love cars, in 2007 they will have the possibility to listen to all NASCAR Nextel Cup Series, NASCAR Busch Series, and NASCAR Craftsman Truck Series races.
Besides entertainment, Sirius has a series of news and talk channels: ABC News & Talk, BBC World Service, BBC Mundo, Bloomberg, CNBC, Court TV, C-Span, CNN Headline News, Discovery Channel, E Entertainment, two ESPN channels, Fox News, Hispanic Talk, Radio Disney, Sirius Trucking Network, the Weather Channel, the liberal network Air America and more. Besides this, it also includes a gay/lesbian news and talk station.
It seems that Sirius tries to satisfy as many demands they can, judging by the wide variety of programs. And having all of these advantages, Sirius is a really determined challenger for the XM.
In comparison with the XM, the Sirius satellite radio has less quality in sound and the XM’s stereo separation is wider. So, we all hope for improvement.
In terms of gadgets, XM has more technology than Sirius radio. There are no MyFi’s, but instead Sirius has the XACT XTR1 that is a limited portable version of the MyFi. And Sirius has no turners with TiVo-like features as the equipments provided by XM. There are companies like Alpine, Audiovox, Blaupunkt, Clarion, Delphi, Jensen, JVC, Kenwood, Sanyo, and Tivoli that produce Sirius hardware.

Satellite Radio 101
Broadcasting digital radio via satellite is not something new and concepts of doings this have been with us for a few years. From the early days of satellite radio, companies like Dish Network have offered digital audio channels as part of their programs. The breakthrough in popularity of satellite radio, however, happened just recently, when the technology became more permissive.
Satellite radio was very rare on moving locations, such as boats or cars, mostly because there was the need for some expensive equipment – a tracking dish. This was a strong deterrent which kept satellite radio quite unknown by the general public. Today, however, one can receive digital audio satellite broadcasts by using a small, GPS-like antenna. This greatly increased the feasibility of the satellite radio systems and more and more vehicle owners began considering satellite radios as a good source of music and news.
The Birth Of Satellite Radio In The United States
When the U.S. Federal Communications Commission (FCC) allocated a spectrum in the "S" band (2.3 GHz) for the broadcasting of digital radio services in 1992 no one thought the amplitude that the system would take in the future. From the initial Digital Audio Radio Service (DARS) things progressed until two companies were given licenses to broadcast digital radio in 1997.
These two were American Mobile Radio (today known as XM Satellite Radio) and CD Radio (presently called Sirius Satellite Radio). The fact that satellite radio is nationwide makes it a very attractive media channel, both for commercial and non-profit organizations. The two companies that initiated the development of satellite radio saw the huge potential it had, since it wasn’t confined by the limitations of other terrestrial broadcasters.
Benefits Of Using Satellite Radio
Here are some of the most noteworthy benefits of having a satellite radio system:
- No more geographical limitations – since the radio program is broadcast through a satellite you don’t have to switch radio stations every time you leave a certain coverage area.
- The digital quality of the satellite radio has some amazing benefits on its own. There are no noise disturbances that were traditional to FM and AM broadcasts. The transmission is crystal clear and satellite radio receives some valuable points when broadcasting quality is concerned.
- Analog radio stations simply cannot broadcast the full range of sounds available through digital satellite radio.
- Both XM Radio and Sirius Radio can be picked up on all the US territory and they are also available in some parts of Canada and Mexico.
Satellite Radio Technology
Each of the major satellite radio services uses its own equipment to broadcast the signal to their clients. The competition is tight and customers have to “pick sides” in order to benefit from satellite radio broadcasting. You have to choose your preferred company and purchase adequate receivers for that particular company. Both XM Radio and Sirius Radio provide their clients with different ways of receiving their services.
The field where most competition takes place is in the negotiation with the major automobile manufacturers. Both XM Radio and Sirius Radio have deals with the auto industry giants in order to offer their services and equipment as optional on the car models they produce. Other partnerships were created with audio equipment manufacturers, who now offer satellite radio transceivers and matching headsets. The most recent shock in the satellite radio universe was caused by the production of portable MP3 player-like satellite radio receivers.
The Future Development Of Satellite Radio
One of the main problems of satellite radio was addressed by the main satellite radio broadcasters. Since you need to be in the line of sight of the satellite to receive the transmission, different problems appeared with mobile satellite radio receivers, especially when different landscaping objects blocked the direct transmission. To solve this, land based devices were installed in order to eliminate the lack of direct satellite transmission.
Another interesting aspect related to satellite radios is that they approached their service offers from a different perspective than traditional radio broadcasters. Instead of airing commercials they charge a subscription fee. For many people, this is actually the best alternative, since they get an almost 100% content broadcast (whether it’s music or talk shows) without the 10-12 minutes per hour of annoying commercials. In most cases, the monthly subscription for satellite radio is of around $12.

The Development Of Digital Multimedia Broadcasting
Satellite radio systems are actually part of a larger group of broadcasting mediums, which specialists refer to as Digital Multimedia Broadcasting or DMB. This digital transmission system is used in order to send data to different receivers such as radios, television sets or mobile phones and PDAs.
There are two different ways of using digital multimedia broadcasting - S-DMB which is broadcasting via a satellite or T-DMB which uses terrestrial emitters. The complexity of the entire digital multimedia broadcasting field is huge. Out of all the features and characteristics digital broadcasting offers, satellite radio is probably the most spectacular as it generated immense interest and triggered an intense competition between the two main satellite radio broadcasters, Sirius and XM Radio.
The development of satellite radio and other forms of digital broadcasting is spectacular because it offers two main qualities that terrestrial emitters are deficient in: quality and coverage. In the case of satellite radio, for example, the sound quality from a satellite broadcast is much higher than AM or FM broadcasts, as the hissing noises and transmission disturbances are eliminated.
Technical Features Of Digital Multimedia Broadcasting - Overview
Whether it refers to television, satellite radio or cell phone transmissions, digital multimedia broadcasting is based on the Eureka 147 DAB standard. Digital television uses the T-DMB which is made for transmissions on frequency bands III (VHF) and L (SHF). T-DMB is an ETSI standard (TS 102 427 and TS 102 428).
T-DMB uses MPEG-4 Part 10 (H264) for the video and MPEG-4 Part 3 BSAC or HE-AAC V2 for the audio. When it comes to satellite radio, there were a few issues to be resolved by the main satellite radio broadcasters. The satellite radio receiver needs to be in the line of sight of the satellite to receive the transmission – and there is the problem of having different landscaping objects block the direct transmission.
Land based devices were installed in order to eliminate the lack of direct satellite transmission. Since the wider spectrum of broadcasts has to be covered, digital multimedia broadcasting uses OFDM-4DPSK modulation and a chip of T-DMB receiver is also provided by MPEG-2 Transport Stream De-multiplexer. This helps reduce the negative effects of shadowing and fading, present in many digital transmissions.
The Future Of Digital Multimedia Broadcasting
The transfer from the analog world to the digital one is obvious in all fields of work. Since digital multimedia broadcasting is developing so quickly, there is a silent battle going on between the new age digital technology and the classic analog one. OF course, many compare the transition from the analog to the completely digital era with the way audio cassettes were replaced by CDs and later on even DVDs.
However, the development of digital multimedia broadcasting is slower since it happens on so many levels at the same time. Digital television is taking us into new spaces that are basically hybrids of the features of regular TV and characteristics of the Internet. Satellite radio is also taking huge leaps forward, with more and more programs having satellite radio exclusivity. There are even discussion of moving events like the MLB exclusively on satellite radio, which would provide one of the first deadly strikes against terrestrial radio broadcasting.
Digital data transmission is fast and accurate, and so far reality proves that the satellites used in order to facilitate broadcasting and reliable. Most digital multimedia broadcasting companies that own satellites also have backup ones ready to go in orbit and replace a defective one. Some other benefits of digital multimedia broadcasting recommend it as a next step in the development of broadcasting. From the consumer’s point of view, the quality and interactivity options of digital TV or satellite radio broadcasts are important features. Although most digital multimedia broadcasting channels and technologies are still complex and sometimes expensive, the evolution of digital broadcasting seems to be here to stay.

The Development Of Satellite Radio In The US
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 Radio’s 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.
On the other hand, some of XM Radio’s 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.
The Development Of Satellite Radio In The US
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 Radio’s 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.
