Construction of the Analog Radio Over Fiber Technology Testbed with Linux PC-Based WiFi Access Points

We aim to realize a beyond 5th generation (B5G) smart mobile fronthaul (SMFH) that utilizes analog radio over fiber (A-RoF) transmission technology and optical power feed technology by applying newly developed Hollow-Core Fiber. In this paper, to evaluate the feasibility of the SMFH, we will report the successful construction of a A-RoF testbed using an unlicensed WiFi 5 GHz band signal provided by a Linux PC-based access point instead of a licensed 5G sub 6 GHz band signal.
