Study of Radio over Fiber Transmission with a Single Line in Ring Topology for Deployment of MIMO Antenna Access Points in a Cell-less Network

The massive growth of wireless traffic goes hand in with the deployment advanced radio interfaces as well network densification. This has a direct impact on access architecture, which today is moving from centralized to distributed deployments through use large number points (APs). paper verifies feasibility deploying multiple APs series single line ring topology cell-less network. On one hand, this technique will further improve communication capacity and flexibility Radio-over-Fiber (RoF) based mobile system reduce its construction cost. And other solution achieve cell-free Multiple-Input Multiple-Output (MIMO) architecture cost-effective fronthaul solution. First, passive optical add/drop multiplexer (OADM) used extract add downlink uplink signals remote kilometer. Then, model developed version 17 Optisystem software. results obtained showed that quadrature amplitude modulation (QAM) does not adapt multi-carrier transmission deploy several AP line. Thus, performance degradation increases when integrated increases.
