Cellular radio system for executing hopping

PURPOSE: To provide a base station for a cellular communication system having a serial interface in order to directly connect the base station to a base station controller on a time division serial bus. CONSTITUTION: Traffic data are received from the base station controller 30 through the serial interface 41. A channel coder 31 encodes the traffic data and selectively outputs the encoded data so that the data are extracted by other base stations 20, 22. The base station 20 successively transmits the encoded data as radio signals in accordance with a hopping sequence. COPYRIGHT: (C)1995,JPO
