    In this paper, we present a scalable high speed Wband (75-110 GHz) fiber wireless communication system. By using an optical frequency comb generator, 3-channel 8.3 Gb/s/ch optical orthogonal frequency division multiplexing (OOFDM) baseband signals in a 15 GHz bandwidth are seamlessly translated from the optical to the wireless domain. The W-band wireless carrier is generated from heterodyne mixing the OOFDM baseband signal with a free-running laser. A W-band electronic down-converter and a digital signal processing (DSP) based receiver is used. 3-channel QPSK-OFDM W-band wireless signals are transmitted over 0.5 m and 2 m air distance with and without 22.8 km single mode fiber, respectively, with achieved performance below the forward error correction (FEC) limit.
