Dual-RoC: Dual Radio-over-Copper Remotization for C-RAN Architecture in 5G Deployments

The workshop W1 is devoted to the dissemination of the results of the project TRIANGLE: 5G applications and devices benchmarking (https://www.triangle-project.eu/). The efforts for demonstrating the performance of 5G devices, services and apps facing the challenging requirements that 5G poses have been a very active research area during the last year. Moreover, with the release of the first version of 5G NR standard in December 2017, the activities in this field have been intensified. In this sense, there are a wave of initiatives from mobile operators, manufactures and research institutions for demonstrating 5G uses cases (enhanced, ultra-reliable low-latency communications, massive IoT, V2X, etc.) in testbed experiments and trials. At this workshop we look for a meeting place for the exchange of knowledge, experiences and best-practices learned in the different testbeds and trials deployed all over the world. The workshop proposes the organization of activities such as poster presentations, demos and panels, as well as technical papers and keynotes presentations, to facilitate the exchange of the experiences and views between the attendees. The workshop will cover issues related to performance evaluation of connected verticals, network and components towards an end to end network performance evaluation in 4.5G to 5G technology. Specifically the topics includes, but not limited to, advances in modelling, simulation, testbeds, trials, tools, drive tests, KPI and QoE computation; all of them in the context of the end-to-end performance analysis of mobile applications, services and devices.

Next generation (5G and beyond) communication networks are expected to incorporate the pre-existing LTE and WiFi connectivity of all the interconnected devices with multiple available interfaces, guaranteeing high-rate/low-latency communications. In this context, Dual-RoC is the integration of Multi Radio Access Technology (RAT) into a copper-based Centralized Radio Access Network (C-RAN) architecture. Dual-RoC is proposed and validated here as it is an attractive solution, especially for indoor deployments. The objective of Dual-RoC is thus to experimentally observe the interplay between an all-analog C-RAN architecture based on LAN cables and Multi-RAT. In particular, in this paper we demonstrate experimentally and for the first time the capability of LAN cables to simultaneously relay both LTE and WiFi signals to commercial devices using all-analog relaying over copper cables.
