5G Wireless Transport in a PON Context: An Overview

摘要: The high capacity of future 5G wireless networks must be supported by equivalent high-capacity fixed for backhaul and fronthaul (x-haul) transport. Especially the trend toward densification radio networks, in which many small cells are located next to macrocells, will call cost-efficient x-haul solutions meet overall business case targets. Optical access technologies bear great potential offer low-cost these transport links. Starting from requirements on bandwidth, latency, other critical parameters ITU-T Q2/SG15 has elaborated a generic approach how employ PON various functional split architectures networks. proposed presented discussed recently released supplementary document G.Sup66, "5G Wireless Fronthaul Requirements Context," October 2018. This article provides high-level summary findings Supplement G.Sup66.
