Abstract

Digital Radio over fibre (DRoF) transmission has long been considered as a promising solution for providing multiple wireless services over a single optical-wireless infrastructure for indoor and last-mile wireless coverage. However, with the increasing number of services and fast growing requirement of Internet of things (IoT), the existing technologies are not able to meet the demand of network convergence due to high capital expenditure (CAPEX) and operating expenditure (OPEX) in managing the vast amount of digitised data. In this paper, we demonstrate a compact multiservice hybrid fibre radio scheme for both downlink and uplink where a novel digital signal processing method and a novel fronthaul protocol are implemented with high bandwidth efficiency. The system uses pluggable modular RF frontend and digital cards so as to support the increasing services dynamically. Both RFID based IoT services and several cellular services from mobile network operators (MNOs) are converged onto a single <6Gbps optical link with high spectral efficiency, modulation accuracy and RF performance. The system is experimentally demonstrated and shows low EVM for all cellular services provided from China Unicom and high detection rate and localisation accuracy for the RFID service carried over 20km optical fibre link.
