5G Wireless Evolution White Paper Towards a Sustainable 5G
1. Introduction
5G is being globally deployed and commercially lunched. With the world’s leading mobile network operators accelerating their commercial rollout of 5G networks, it is expected that more than million 5G base stations will be deployed to bring 5G services to 58% of the world's population, and the number of global 5G connections will exceed 100 billion beyond 2025.
5G is not only deeply rooted in the traditional consumer electronics industry, but also receives extensive attention in the manufacturing industry. Operators are increasingly endeavoring to bring the expertise of managing a high quality air-interface, network operation, optimization, and service interoperability to connect people, homes, industrial equipment, and so on.
In anticipation of significant 5G penetration and the 5G traffic volume by 2025, continuously improving 5G networks is inevitable. Especially, 5G evolution envisions commercializing today’s attractive use cases, as well as bringing ne
