Abstract: System for wireless transmission of multiple information signals making use of digital time division circuits between a base station 11 and a number of subscriber stations 10. The subscriber stations can be fixed or mobile. The number of time division circuits is determined by the transmission quality of the signals. The base station 11 is connected to an external analog and/or digital information network 12. The information signals are voice, data, facsimile, video, computer or other instrumentation signals. The modulation level of the signals and the system's power are adjusted in dependence on the signal error detection in the system. The system assures spatial differentiation by making use of several antennas at an interval from each other, so that relatively strong signal reception is achieved despite fading. The base station 11 operates over several radio frequency channels, and the operation of each channel pair occurs by a combination of a transmission channel circuit for processing of a given number of information signals arriving simultaneously over telephone lines, which are sent out simultaneously over a given radio frequency channel to various subscriber stations 10, and a receiving channel circuit for processing of signals which are received simultaneously from various subscriber stations via a given radio frequency channel, in order to form information signals for transmission over the telephone lines.

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.
