Abstract
Systems and methods are provided for network communication using wireless base stations and an optical orthogonal frequency division multiple access (OFDMA) signal generated on an optical wavelength, with the optical OFDMA signal being composed of a plurality of OFDMA subcarriers. A multi-level modulator modulates each of the plurality of OFDMA subcarriers. A single optical wavelength propagates each of the plurality of OFDMA subcarriers to different base stations; a passive optical splitter delivers the optical OFDMA signal to different base stations; and an OFDMA subcarrier de-multiplexer delivers and extracts traffic for each of the base stations in an electronic-domain, wherein the extracted traffic is remodulated in a wireless signal format. Antennas at each of the base stations transmit wireless signals, and the wireless signals are recovered and processed from the base stations.
