Satellite radio guide for Novice Users
Gagandeep Dhaliwal
A satellite radio or subscription radio (SR) is a digital radio
that receives signals broadcast by communications satellite that
covers a much wider geographical range than normal radio signals.
The satellite radios function anywhere there is line of sight
between the antenna and the satellite, given there are no major
obstructions, such as tunnels or buildings. SR audiences can
follow a single channel regardless of location within a given
range.
As the technology requires access to a commercial satellite for
signal propagation, SR services are commercial business entities
(not private parties), which offer a package of channels as part
of their service --requiring a subscription from end users to
access its channels.
The satellite radios use the 2.3GHz S band in North America, and
generally shares the 1.4GHz L band with local Digital Audio
Broadcast (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.
Presently, the main radio satellite service provider in Europe,
Asia and Africa is WorldSpace. WorldSpace has its own satellites
covering most of Europe, Asia and Africa.
XM Satellite Radio and Sirius Satellite Radio are the two radio
satellite gains in the United States and entire North America. A
monthly fee is charged for both services. Sirius offers a one
time fee plan of nearly $500 valid for the lifetime of the
equipment. These offer the news, weather, sports, and several
music channels.
The Canadian Radio-television and Telecommunications Commission
(CRTC) commenced the Canada's first satellite radio operations
on November 1, 2004.
