Abstract:
1. A terminal connected to a wire communication network for radio communication, wherein said terminal includes at least one of transmitter means and receiver means, wherein said transmitter means receives a first baseband signal in a particular format from said wire communication network, and modulates a carrier wave using the received first baseband signal into a transmission signal without translating the particular format of the first baseband signal into a different format, wherein the transmission signal is transmitted via a transmitting antenna, wherein said receiver means receives a signal via a receiving antenna, and demodulates the received signal into a second baseband signal, wherein the second baseband signal is transmitted from said receiver means to said wire communication network without translating a format of the second baseband signal into a different format, wherein said wire communication network includes an optical fiber link for transmitting a signal within said wire communication network, wherein the first baseband signal received by said transmitter is an optical signal, and wherein the second baseband signal transmitted from said receiver means is an optical signal, wherein said transmitter means includes a light controlled oscillator for generating the carrier wave of a predetermined nominal frequency, wherein the first baseband signal received by said transmitter means is applied to said light controlled oscillator, and wherein said light controlled oscillator generates, as the transmission signal, a signal of a frequency shifted from the predetermined nominal frequency according to an intensity of the applied first baseband signal.
