Satellite communication system with variable number of satellite communication channels

摘要

A central station is connected to a plurality of remote stations through in-bound channels and out-bound channels. Data is transmitted from the respective remote stations to the central station through the in-bound channels and data is transmitted from the central station to all of the remote stations through the out-bound channels. Possibility of data transmission delay is reduced by changing the number of either or both of the in-bound channels and the out-bound channels according to a variation of amount of data transmitted/received between the remote statios and the central station. <IMAGE>
