Title:
【発明の名称】多重音声及び/又はデータ信号通信を単一又は複数チャンネルにより同時に行うための加入者RF電話システム
Document Type and Number:
Japanese Patent JP2816349
Kind Code:
B2
Abstract:
A master station communicates with the main network, whilst a set of mobile or fixed sub stations of voice or data users share the channel using time division multiplexing. The number of time division channels available depends on the quality of the transmission links, power and modulation index. The rate of errors is detected to maintain a specified condition of operation. When all available channels are occupied a busy signal is transmitted by the master station. The effect of multiplexing on the sub-links gives apparent simultaneous bidirectional transmission.
