RADIO COMMUNICATION SYSTEM

摘要

A radio communication system wherein the level of a radio signal received by a relay apparatus (20) can be confined within a predetermined dynamic range. In a control apparatus (10), a transmission part (102) converts a downstream electric signal to a downstream optical signal and transmits the downstream optical signal to the relay apparatus (20) via an optical transmission path (40). The relay apparatus (20) then converts the received downstream optical signal to the downstream electric signal and transmits this downstream electric signal as a radio signal from a transmission/reception antenna part (204) to a radio communication terminal (30). In the relay apparatus (20), a level adjustment part (207) adjusts the level of radio signals, which is to be transmitted by the relay apparatus (20), such that the reception intensity of radio signals to be received by the relay apparatus will be confined within a predetermined range.
