Server-assisted position determination in a radio network

Image Number 4 for United States Patent #6754583.

A client unit (102) has a client GPS receiver (104) integrated with a two-way-radio transceiver (108) and a client manager (116) for performing server-assisted global position fixes. A server unit (120) is associated with a second two-way-radio transceiver (126) and a server manager (130). The client and server managers (116 and 130) function as communication managers, and each has modules for detecting RF channel traffic, enabling transmitter portions of the transceivers (108 and 126) to transmit satellite data and position information only when there is no traffic on the RF channel.
