Abstract

PURPOSE:To enable to receive and give the data and audio information with good efficiency for a plurality of radio terminal stations and central station depending on each status, by placting the receiver of each station in operating condition at all times and constituting the digital signal delivered from the central station. CONSTITUTION:The central station 2 is located at the center of districts where a plurality of terminal stations 1-1-1-N are scattered normally to cover the entire system area with less transmission power, and the central and terminal stations deliver or receive audio and data with less number of radio channels and carrier frequency of upward and downward directions F1 and F2. The transmitter of the terminal station is under the control of the central processor provided at the center station 2, individual call, group call and polling call are possible to the terminal station where the receiver is always in operating condition from the center station 2. Further, the audio signal from the termainl station 1-M, for example, transmitted in F1 is received by the center station 2 and its is transmitted to other terminal station 1-N in F2, enabling the bidirectional communication between the terminal stations 1-M and 1-N.
