     A satellite radio or subscription radio (SR) is a digital radio that receives signals broadcast by communications satellite, which covers a much wider geographical range than terrestrial radio signals.

      SR functions any place 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.

       Because 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. Currently, the main SR providers are World Space in Europe, Asia and Africa, and XM Radio and Sirius in North America. All are proprietary and non-compatible signals, requiring proprietary hardware for decoding and playback. These and other services have news, weather, sports, and several music channels.
