Abstract
A radio signal relay device such as satellite is used to cover several relatively small geographical regions with relatively narrow beams as well as a relatively large geographical region with a single beam. This relatively wide beam permits legacy equipment to be used. A transmitting device in a beam transmits a signal to the relay device, which in turn retransmits the signal to a receiving device. The transmitting devices, relay device, and receiving devices synchronize communication by using a particular mode of communication which includes a band of carrier frequencies and a protocol. In addition to communicating like mode signals from a transmitter to a receiver, the relay device may be used in a dual mode communication system to translate signals from the one mode to another. A translator may direct a transmitter to modulate a signal on a different carrier frequency, convert one protocol into another protocol, or both.
