Optical fibre fronthaul for the disaggregated 6G RAN
Nathan Gomes, UCL
Radio access network (RAN) disaggregation is viewed as essential for meeting the bit-rate, spectral efficiency, user density and energy efficiency demands of future mobile networks. However, demands are then placed on the latency and bit-rate requirements of the fronthaul links which connect the disaggregated remote radio units to the more centralised functional units (usually termed distributed and central units). Optical fibre communications can meet such demands, but with the links becoming increasingly widespread as future mobile systems are deployed, the use of low-cost technology will be essential. Further, as 6th generation (6G) mobile networks target energy efficiency improvements of two orders of magnitude, the energy consumption of the fronthaul will become a key consideration. A fronthaul transmission system which can respond to demand, reducing its line rate and its energy consumption when the mobile traffic is lower, can play an important role in overall energy efficiency strategies.
Fixed access evolution towards 6G networks
Maxim Kuschnerov, Huawei Technologies
The arrival of 6G wireless will transform fixed access networks and its architecture similarly to 5G. We will analyze the implications of 6G on optical fiber access and discuss the joint evolution of wireless, residential and private line access as well the changing drivers for the bandwidth growth. A technical analysis of different physical layer technologies will be shown and evaluated with respect to their fit into the next generation access evolution.
