A satellite radio or subscription radio (SR) is a digital radio signal that is broadcast by a communications satellite, which covers a much wider geographical range than terrestrial radio signals. This article needs to be cleaned up to conform to a higher standard of quality. ... U.S. military MILSTAR communications satellite A communications satellite (sometimes abbreviated to comsat) is an artificial satellite stationed in space for the purposes of telecommunications. ...


Satellite radio is currently at the forefront of the evolution of radio services in some countries, notably the United States. Mobile services, such as Sirius, XM, and Worldspace allow a listener to roam across an entire continent, listening to the same audio programming anywhere they go. Other services, such as Music Choice or Muzak's satellite-delivered content require a fixed-location receiver and a dish antenna. In all cases, the antenna must have a clear view to the satellites. In areas where tall buildings, bridges, or even parking garages obscure the signal, repeaters can be placed to make the signal available to listeners. For Music Choice in United Kingdom, see Music Choice Extra Music Choice is a name used by two different companies, one in the US and one in Europe. ... Muzak Holdings LLC is a company, founded in 1934, that is best known for distribution of music to retail stores and other companies. ... In broadcasting, a translator is an FM radio station or a TV station which acts as a full-duplex repeater. ...


Radio services are usually provided by commercial ventures, and are subscription-based. The various services are proprietary signals, requiring specialized hardware for decoding and playback. Providers usually carry a variety of news, weather, sports, and music channels, with the music channels generally being commercial-free.

For other uses, see Music (disambiguation). ...


In areas with a relatively high population density, it is easier and less expensive to reach the bulk of the population with terrestrial broadcasts. Thus in the UK and some other countries, the contemporary evolution of radio services is focused on Digital Audio Broadcasting (DAB) services, such as HD Radio rather than satellite radio. Digital Audio Broadcasting (DAB), also known as Eureka 147, is a technology for broadcasting of audio using digital radio transmission. ... HD Radio is an in-band on-channel (IBOC) digital radio system created by iBiquity for broadcasting via existing FM and AM radio stations. ...


Satellite radio providers

United States

In North America, there are two satellite radio companies, XM Satellite Radio and Sirius Satellite Radio. These two former rivals have announced their intention to merge, which would create a single satellite radio entity in the United States with nearly 14 million subscribers [citation needed]. “XM” redirects here. ...

XM Satellite Radio logo Sirius Satellite Radio logo On February 19, 2007, Sirius Satellite Radio and XM Satellite Radio announced a merger that would combine the two radio services and create a single Satellite Radio network in the United States and Canada. ...


Canada

XM Canada and Sirius Canada, operated as separate entities from their American counterparts with 51% ownership by different Canadian companies, may eventually merge as well. Sirius Canada's market share is slightly more than that of XM with 300,000 [1] and 270,000[2] paid subscribers respectively. XM Canada owns a lucrative contract with the NHL, which it feels would bring a great deal to the merged company in hockey-crazed Canada. XM Radio Canada is the operating name of Canadian Satellite Radio Inc. ...

The European Space Agency, however, has unveiled a plan and a prototype to use pre-existing satellites to construct a satellite radio service. The satellites were part of Europe's original satellite TV system, and are nearing the end of their operational lives. As satellite radio doesn't require the exact satellite positioning that a dish-based TV system does, their lives can be extended even though the satellites are drifting out of their original orbits. “ESA” redirects here. ...


Other areas

Areas outside of the Worldspace, XM, or Sirius footprint, including Australia, New Zealand, and the Hawaiian Islands, do not yet have access to mobile satellite radio services. There are several satellite TV services which operate in these areas and can provide audio programming via dish antennas.

Business applications

Satellite radio, particularly in the United States, has become a major provider of background music to businesses such as hotels, retail chains, and restaurants [citation needed]. Compared to old-line competitors such as Muzak, satellite radio's significantly lower price, commercial-free channel variety, and more reliable technology make it a very attractive option. Both North American satellite radio providers offer business subscriptions, though given the merger of XM Satellite Radio with Sirius, the future of XM for Business is uncertain. Sirius' commercial services are provided nationally by third-party partner Applied Media Technologies Corporation [citation needed].

System design

Satellite radio uses the 2.3 GHz S band in North America, and generally shares the 1.4 GHz L band with local Digital Audio Broadcasting (DAB) stations elsewhere. It is a type of direct broadcast satellite, and is strong enough that it requires no satellite dish to receive. Curvature of the Earth limits the reach of the signal, but due to the high orbit of the satellites, two or three are usually sufficient to provide coverage for an entire continent. The S band ranges from 2 to 4 GHz. ... North America North America is a continent[1] in the Earths northern hemisphere and (chiefly) western hemisphere. ...

Local repeaters similar to broadcast translator boosters enable signals to be available even if the view of the satellite is blocked, for example, by skyscrapers in a large town. Major tunnels can also have repeaters. This method also allows local programming to be transmitted such as traffic and weather in most major metropolitan areas, as of March 2004. A repeater is an electronic device that receives a weak or low-level signal and retransmits it at a higher level or higher power, so that the signal can cover longer distances without degradation. ...

Each receiver has an Electronic Serial Number (ESN)-Radio ID to identify it. When a unit is activated with a subscription, an authorization code is sent in the digital stream telling the receiver to allow access to the blocked channels. Most services have at least one "free to air" or "in the clear" (ITC) channel as a test. For example, Sirius uses channel 184 "Sirius Weather & Emergency". Electronic Serial Numbers (ESNs) were created by the FCC to uniquely identify mobile devices from the days of AMPS in the United States in the mid-1980s on. ...

Satellite radio vs. other formats

Satellite radio differs from AM or FM radio, and digital television radio (or DTR) in the following ways. The table applies primarily to the United States. AM broadcasting is radio broadcasting using Amplitude Modulation. ... FM broadcasting is a broadcast technology invented by Edwin Howard Armstrong that uses frequency modulation (FM) to provide high-fidelity sound over broadcast radio. ... Digital television radio (or DTR) is an informal term which describes the music channels that are provided with a digital television service. ...

Radio format Satellite radio AM/FM Digital television radio (DTR)
Monthly fees US$12.95 and up None Very low — DTR represents a small portion of the total monthly television fee
Portability Available Prominent None — a typical set consists of a stereo attached to a television set-top box (the primary function of the set top-box is normally designed for cable or satellite television viewing)
Listening availability Very high — a satellite signal's footprint covers millions of square kilometres Low to moderate — implementation of FM service requires moderate to high population densities and is thus not practical in rural and/or remote locales, AM travels great distances at night Very high
Sound quality Varies² AM: Usually very low, but can be the highest
FM: Usually Moderate, but can be very high
Varies²
Variety and depth of programming Highest Variable — highly dependent upon economic/demographic factors Variable - dependent on the satellite television provider and the various packages they provide and on the user's subscription
Frequency of programming interruptions (by DJs or commercial advertising)³ none to high - mostly dependent on the channels which some have DJs, most channels are advertisements free because of the paid subscription model of satellite radio Highest4 none to low - dependent on the provider, however it's common that some stations will have DJs. usually no advertisements (DirecTV and Dish Network both claim to provide advertisement free content)
Governmental regulation Yes5 Yes — significant governmental regulations regarding content6 Low to none 5

² The sound quality with both satellite radio providers and DTR providers varies with each channel. Some channels have near CD-quality audio, and others use low-bandwidth audio suitable only for speech. Since only a certain amount of bandwidth is available within the licenses available, adding more channels means that the quality on some channels must be reduced. Both the frequency response and the dynamic range of satellite channels can be superior to FM, and even the worst channels are still superior to most AM radios, but a very few AM tuners are equal to the best FM broadcasts when tuned to a local station, even if not capable of stereo. AM broadcasting is radio broadcasting using Amplitude Modulation. ... FM broadcasting is a broadcast technology invented by Edwin Howard Armstrong that uses frequency modulation (FM) to provide high-fidelity sound over broadcast radio. ... Digital television radio (or DTR) is an informal term which describes the music channels that are provided with a digital television service. ...

5 In the United States, the FCC regulates technical broadcast spectrum only. Program content is unregulated. However, the FCC has tried in the past to expand its reach to regulate content to satellite radio and cable television, and its options are still open to attempt such in the future. The FCC does issue licenses to both satellite radio providers (XM and Sirius) and controls who holds these licenses to broadcast. The FCCs official seal. ...


6 Degree of content regulation varies by country, however the majority of industrialized nations have regulations regarding obscene and/or objectionable content.


United States

In the United States, two companies operate satellite radio services: XM Satellite Radio and Sirius Satellite Radio. A monthly fee is charged for both services (as of 2005 Sirius also offers a one time fee of nearly $500 valid for the lifetime of the equipment). Originally some XM music channels had commercials, while Sirius was commercial-free. Both stations have commercial-free music stations and talk and news stations that include commercials. XM uses fixed-location geostationary satellites in two positions, and Sirius uses three geosynchronous satellites in highly elliptical orbits passing over North and South America, to transmit the digital streams. The net difference is that the Sirius signal comes from a higher elevation angle in the northern part of the U.S., and even more so in Canada. (This higher angle makes Sirius' signal less likely to drop out on cities, but more likely to drop out in parking garages, gas stations, tunnels, and other covered spaces.) “XM” redirects here. ...

Both services are available mainly via portable receivers in automobiles, but both have many accessories so one can listen at home through a home stereo, with a portable boombox, or online through a personal computer. Both services now have some form of receiver that is completely portable. In radio terminology, a receiver is an electronic circuit that receives a radio signal from an antenna and decodes the signal for use as sound, pictures, navigational-position information, etc. ... This article does not cite any references or sources. ...


Satellite radio's chief asset is the fact that it is not localized: drivers can receive the same programming anywhere in the footprint of the service. A stop at any truck stop will demonstrate the popularity of XM among long-haul drivers. In addition, both XM and Sirius carry programming that is simply not feasible on commercial radio stations. Specialty stations cover things such as family talk, radio drama, classical music, and live events. A truck stop is a commercial facility that provides fuel, parking and usually food and other services to long-haul trucks. ...

Success so far

As of January, 2007, XM has claimed "7.6 million" subscribers, while Sirius claimed "6 million" [citation needed]. One critical factor for the success of satellite radio is the deployment of in-car receivers. Both Sirius and XM have attempted to convince automakers to equip vehicles with their receiver. As of 2007, the following manufacturers offer satellite radio as original equipment: “Car” and “Cars” redirect here. ...

Sirius has an exclusive contract for VW and Audi vehicles from 2007 through 2012 [citation needed]. Those brands previously offered both services. GM, Honda and Suzuki are all major investors in XM, so not surprisingly, Sirius is not offered as options in their vehicles.

One of the challenges for satellite radio has been to move away from cars and into the homes of consumers. Several portable satellite radio receivers have been made for this purpose. XM satellite radio has developed the XM2go™ line of "walkman-like" portable receivers, such as the Delphi MyFi™, the Pioneer AirWare™ and Giant International's Tao. Polk Audio makes a component-style home XM Reference Tuner [3] and a tabletop entertainment system, the I-Sonic [4], with XM capability. Sirius has developed the Kenwood Portable Satellite Radio Tuner, Sirius S50, Here2Anywhere and the Sirius Stiletto 100.

In its decision, the CRTC required the following conditions from the satellite radio licensees:

  • A minimum of 8 channels must be produced in Canada and for each Canadian channel 9 foreign channels can be broadcast.
  • At least 85% of the content on the Canadian-produced channels (whether musical or spoken word) must be Canadian.
  • At least 25% of the Canadian channels must be French-language stations.
  • At least 25% of the music aired on the Canadian channels must be new Canadian music.
  • At least 25% of the music played on the Canadian channels must be from up-and-coming Canadian artists.

These conditions were an extension of the existing Canadian content rules applicable to all broadcasters in Canada. The applicants had until 13 November 2005 to notify the CRTC of their decision. Both companies managed to negotiate the standards a little to their favor, and in return they would instead play 50% French content as opposed to 25%. Also, XM Canada succeeded in getting an extra 5 channels of National Hockey League Play-by-Play onto their platform, without an additional channel creation, by agreeing to cover every Canadian team's game during the season.

CHUM appealed the decision, claiming they would not survive if Sirius and XM both were allowed in the Canadian market, and that the licence conditions regarding Canadian content imposed on Canadian Satellite Radio and Sirius Canada were too lax. Canadian Satellite Radio and Sirius Canada countered that CHUM was simply trying to create a monopoly in the Canadian market. A monopoly (from the Greek language monos, one + polein, to sell) is defined as a persistent market situation where there is only one provider of a product or service, in other words a firm that has no competitors in its industry. ...


In late August 2005, Heritage Minister Liza Frulla asked the federal cabinet to review the CRTC decision, and possibly send it back to the CRTC for further review. Lobbyists complained that the CRTC decision did not require enough Canadian content from the broadcasters. The broadcasters responded by promising to add additional Canadian and French content.

A large number of radio stations are available free-to-air on geostationary satellites targeting Europe throughout the Ku band, but these require fixed dish installations and as a result, are impractical for use in vehicles. Reception is often tied to a satellite television decoder. Both analogue stations, as subcarriers in SÉCAM and PAL analogue satellite signals, and digital, as DVB-S streams and Astra Digital Radio subcarriers, are in use. Free-to-air is a phrase used to describe television and radio broadcasts which are available without subscription and without decryption (pay-TV). ...

Ku band

The European Space Agency has proposed to use older satellites, which are no longer perfectly geostationary but still have enough fuel to be sufficiently geosynchronous, as a means to transmit satellite radio. However, because the extremely line-of-sight Ku band (11GHz) is even more prone to dropouts than the L and S bands (around 2GHz), programming would be sent in segments much like podcasts, for playback at any time. If part of a segment is lost, it can be re-recorded when it is next transmitted. The system's infrastructure would be inexpensive to implement, as time on otherwise unused satellites costs very little, and the non-realtime nature of such a system means it requires no repeaters.
