摘要
5G作为新一代通信技术,以高速率和低延时等特点备受人们推崇,在高清视频、无人驾驶、AI以及远程医疗等诸多领域具有广泛应用前景,也是各个国家争夺技术高峰的制高点。5G技术的应用离不开5G基站建设,而基站供电需求则是5G基站建设所面临的巨大挑战。5G基站供电主要存在5G核心单元模块结构的变化、单基站功率的提升、基站密度的大幅增加、现有市电容量、备电电池供电能力、远程供电以及散热等问题。在此分别从5G基站供电需求和供电技术两个方面对相关问题进行论述,为更好了解相关技术提供参考。
As a new generation of communication technology,5G is highly praised for its high speed and low delay.It has a wide application prospect in many fields,such as HD video,unmanned driving,AI,telemedicine and so on.It is also the commanding point for each country to compete for the technical peak.The application of 5G technology is inseparable from the construction of 5G base station,and the power supply demand of base station is a great challenge for the construction of 5G base station.The main problems of 5G base station power supply are the change of 5G core unit module structure,the improvement of single base station power and the substantial increase of base station density,as well as the existing city capacitance,backup battery power supply capacity,remote power supply and heat dissipation.This paper discusses the related issues from two aspects of 5G base station power supply demand and power supply technology,so as to provide reference for better understanding of relevant technologies.
