Satellite Radio


Satellite radio is one of the biggest improvements in broadcasting since the introduction of FM. Satellite radio signal can be broadcasted for more than 35,000 kilometers (22,000 miles) with complete clarity and high quality sound. You will never get static interferences while listening to over 100 radio channels. The idea behind satellite radio has appeared in 1992, when the United States Federal Communications Commission granted a spectrum of the S band (the 2.3 GHz frequency) for Digital Audio Radio Service. The license to broadcast in that band was allocated to Sirius Satellite Radio and XM Satellite Radio in 1997. Now there are three companies that provide satellite radio in the world: Sirius and XM in Northern America and WorldSpace in Asia, Europe and Africa.

Each of these companies offer different broadcasting systems, since the radio signal of each is proprietary. This means that you will have to buy different hardware depending on your subscription to one of these companies. However, there are three components common to all satellite radio services: the satellites, the ground repeaters and the radio receivers. Different satellite radio companies broadcast the radio signal in different ways. For instance, XM satellite radio uses geostationary satellites which have orbits that are synchronized with the movement of Earth. These satellites are located above the equator. In order to allow subscribers to receive crystal-clear signal despite obstacles such as buildings, hills or bridges, XM satellite radio service has installed a network of repeaters antennas that receive the radio signal from the satellites and retransmit it to the subscriber’s receiver Sirius, on the other hand, uses satellites that have unique elliptical orbits around Earth. These kinds of orbits allow satellites to get higher in the sky than geostationary satellites and this prevents loss of signal. This is the reason why Sirius has fewer terrestrial repeaters than XM.

The Advantages Of Satellite Radio

One of the great advantages of satellite radio is the fact that the programs are not interrupted by commercials. This is because the provider’s 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 receiver‘s 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.

Canadian Satellite Radio

While the United States initiated the satellite radio evolution, Canada is now hot on their trails. The Canadian Radio-television and Telecommunications Commission (CRTC) began hearings in 2004 for applicants ready to develop Canada’s first satellite radio broadcasting. The Canadian satellite radio industry received quite a lot of interest and in the end three main applications were filed: XM filed one in partnership with Canadian Satellite Radio and Sirius filed an application with Standard Broadcasting and the CBC. The third application belongs to CHUM Limited and Astral Media and to many came as a surprise. That was mostly because CHUM Limited and Astral Media came up with a different solution that that proposed by Sirius and XM Radio. CHUM applied for a subscription radio service that is to be delivered through the already existing terrestrial DAB transmitters. In other words, the transmitters would be the ones receiving the satellite transmission, from where they would continue the broadcast to consumer owned receivers. While the CHUM Limited and Astral Media proposal offers an entirely Canadian approach, the first two bring in a blend of US based technology and Canadian broadcasting channels. XM Radio and Sirius had a slight advantage in the fact that the coverage area of their satellites already existed in parts of Canada, so a small audience was already using their services.
Three satellite radio services for Canada

The Canadian Radio-television and Telecommunications Commission (CRTC) approved all three applications in June 2005, but with a series of conditions imposed to the three solicitants. Here they are as required by the CRTC:

•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.

The three companies had to accept these conditions as they are part of the Canadian broadcasting regulations. The US companies and their Canadian partners began negotiations for tilting the rules in their favor.
