Introduction

There have never before been so many options for how to build a cellular radio access network; from fully aggregated gNB to CRAN, control and user plane separation to CPRI or eCPRI. Terms such as backhaul, midhaul and fronthaul are used interchangeably and often interpreted to mean different things by different people. Open RAN initiatives suggest additional ways to decompose the radio network, so what does all of this mean for an optimised network architecture. What is the role of edge compute and how do we dimension, operate and maintain these complex and likely dynamic networks going forward?

Workshop Goals

This IWPC workshop aims to explore all of these questions and more as we aim to find industry consensus, develop best practice and build practical roadmaps to an optimized and future-proof radio access network architecture.
