IBC2023 Tech Papers: 5G Standalone Non-Public Networks: Modernising Wireless Production

Abstract

New spectrum opportunities that facilitate the deployment of 5G Standalone Non-Public Networks are of increasing interest to broadcasters. Modern IP workflows can integrate seamlessly with such networks and the technology is finding an increasing number of applications for wireless production. The cost of 5G network equipment is reducing and a single 5G deployment can potentially replace a plethora of traditional wireless production equipment.

This paper explores the characteristics of current 5G implementations, detailing the strengths and challenges of deploying this new technology. For wireless cameras, many alternative streaming technologies can be used and the trade-offs between reliability, quality, network load and latency are explored. The BBC’s experience of trialling the technology at the Coronation of HM King Charles III is discussed.

Introduction

The opportunities presented by 5G Non-Public Networks (NPNs) for programme making have been the subject of several collaborative research projects (1), (2). Mobile spectrum has traditionally been available only for public network bought at auction. Identifying the value of smaller private networks, spectrum in the 3.8–4.2 GHz is now licensed by Ofcom UK using the shared access licence (SAL) (3). This spectrum forms part of the 5G n77 band.
