Fifth‐generation new radio fiber‐wireless system for long‐reach and enhanced mobile broadband scenarios

Abstract

This work reports the implementation of a fifthgeneration (5G) new radio (NR) fiber-wireless (FiWi) system for long-reach and enhanced mobile broadband scenarios. The proposed 5G NR FiWi system includes a 12.5 km optical distribution network based on radio over fiber technology, a 7.5 km supercell in a rural area using the 700 MHz band, digital pre-distortion (DPD), equalization and a Gbit/s indoor femtocell operating in the 26 GHz band. The 5G NR standard has been applied and DPD and equalization have been efficiently employed to enhance the system performance in mm-waves. Furthermore, experimental results demonstrate successful implementations of a femtocell with 4 Gbit/s throughput and only 4.6% error vector magnitude, as well as a large cell with 33 Mbit/s throughput and 7.51-km reach.

“…The wireless reception can be further enhanced by using wireless signal detection using the techniques discussed in [44]. In addition, the performance of the proposed system is summarized and compared in Table 2 with the state-of-the-art relevant method of the 5G RoF system, which was evidenced in the previous work of the authors in [16] and others in [43], with the same link length and other settings. The wireless reception can be further enhanced by using wireless signal detection using the techniques discussed in [44].…”
