DualRoC: Dual-Radio Radio-over-Copper Remotization for Multi-RAT Centralized-RAN Architecture in 5G Deployments (carried out within the H2020 Triangle Project)
The goal of the project was to validate experimentally the feasibility of remotizing multiple antennas indoors, i.e., over the last 50-100m, by distributing RF signals through the pre-existing Local Area Network (LAN) cabling infrastructure of buildings. This architecture, referred to as Multiple-Input Multiple-Output (MIMO) Radio-over-Copper (RoC) architecture, is a low-cost and low-latency analog Centralized Radio Access Network (C-RAN) solution able to provide dedicated in-building solution to all the buildings that nowadays still suffer from indoor coverage issues. In particular, the ultimate goal of the experiment was to simultaneous distribute indoors both MIMO Wi-Fi and MIMO LTE signals over the same LAN cable.
Project results
The project has been successfully carried out by reaching the relevant objectives. In particular, through a prototype platform purposely developed, it has been experimentally proved that LAN cables are promising candidates to distribute multiple antenna signals indoors: a single LAN cable can be exploited up to several hundreds of MHz bandwidth, and is capable to simultaneously carry MIMO Wi-Fi and MIMO LTE signals without any significant performance degradation.
