Expectation toward the Satellite Communications from the viewpoint of a Cellular Operator

摘要

Some examples of current satellite applications applied into the cellular systems are explained. In conventional usage, satellite circuit was used as the temporary application when severe natural disaster occurs. In recent days, use case of the satellite circuit is to expand into the ordinary operation as a convenient entrance link. In the latter half, we explain about technical and economical expectation to the future satellite communications toward the future cellular network achieve. For example, 5G system request higher performance to the transmission line inside the system. When a satellite communication will be applied into the future cellular, some of performance should be more improve.
