We experimentally demonstrate a seamless hybrid transmission of radio-over-fiber (RoF), radio-over-free-space optics (RoFSO) and millimeter wave wireless link using long-term evolution (LTE) 4/16/64-QAM signals for broadband wireless access applications. The signals are transmitted and evaluated over the hybrid channel consisting of 5 km of standard single-mode fiber (SMF), 2 m FSO under the turbulence level up to 3.2×10-11 m-2/3 and 3.3 m 25 GHz wireless channel. The performance shows that, the error vector magnitudes (EVM) are below the 3GPP standard for 4/16/64-QAM signals. We show that, the bit error rate (BER) for all signals is below the forward error correction limit of 10-3. We also perform simulation analysis at higher bit rates of 10 and 15 Gb/s for the hybrid link of SMF (5 km) and FSO (extended up to 500) m under the turbulence level of 1.3×10-15 m-2/3 for the practical outdoor scenario. We achieved acceptable performance for 4- and 16-QAM at 10 and 15 Gb/s.
