    Abstract

    Fifth generation (5G) mobile communications will require a dense deployment of small cell antenna sites and higher channel bandwidth, in conjunction with a cloud radio access network (C-RAN) architecture. This necessitates low latency and high capacity architecture in addition to energy and cost efficient fronthaul links. An efficient way of achieving such connectivity is to make use of optical fiber based infrastructure where multiple wireless services may be distributed over the same fiber to remote radio head (RRH) sites. In this work, we demonstrate the spectral containment of 4G long term evolution (LTE) signal and 5G candidate waveforms - generalized frequency division multiplexing (GFDM) and universally filtered orthogonal frequency division multiplexing (UF-OFDM), through a directly modulated link. 75 bands of LTE and 10 bands of 5G waveforms are successfully transmitted over 25 km analog intermediate frequency signal over fiber (AIFoF) link through our setup, limited only by the bandwidth of the laser. For the first time, we demonstrate the fronthaul network for providing simultaneous 4G & 5G services by propagating LTE signals in coexistence with UF-OFDM.
