In this paper we investigated two solutions for distributing 802.15.3c signal over Multi-Mode Fiber (MMF) to solve the problem of limited coverage at 60 GHz. The first solution consists of the transmission of the signal at 60 GHz directly over fiber (RFoF) and the second solution consists of the transmission of the signal at intermediate frequency 5 GHz over fiber (IFoF). The millimeter wave is generated using the Optical Carrier Suppression (OSC) technique, and the optical link is based on MMF without optical amplifiers in order to obtain a low cost architecture. The systems are evaluated and analyzed by Bit Error Rate (BER) and Error Vector Magnitude (EVM) performance. The comparison between the two solutions is based on the fiber length, the complexity and cost of the implementation
