Satellite Radio:-

• A satellite providing high fidelity audio broadcast services to the broadcast radio stations is referred to as a satellite radio and is a major revolution in the field of radios.
• Sound quality is excellent in this case due to a wide audio bandwidth of 5-15 KHz and low noise provided over the satellite link.
• Satellite radios like the satellite TV employ GEO satellites and the network arrangement for the satellite radio is more or less identical to that used for TV broadcasting.
• Using point-to-multipoint connectivity, the audio signals from various music channels, news and sports centres are transmitted by the satellite to a conventional AM or FM radio station.
• The signal is then de-multiplexed and the local commercials and information is added in the same way as in a TV network and then sent to the users using terrestrial broadcasting.
• The satellite can also transmit the signal directly to the user’s radio sets.
• Some of the major providers of satellite radio services include Sirius and XM radio of the USA.
