Frequency hopping in digital cellular networks










Image Number 2 for United States Patent #5430713.

A circuit is for providing frequency hopping in a Time Division Multiple Access (TDMA) system. A microprocessor determines the frequency to be transmitted in a particular broadcast frame. A dual port random access member (RAM) provides an interface between the microprocessor and a time division multiplex bus so that the time slots are mapped to addresses in the memory. A plurality of transceivers coupled to the bus transmits and receives at different designated frequencies, the transceivers being chosen for particular users during a particular broadcast frame based on the location in the memory chosen by the microprocessor.
