摘要
5G采用了全新的网络架构、网络切片、大规模天线阵列和超密集组网等技术,具有大带宽、高可靠和低时延的特性,是未来通信发展的方向。5G测试仪器是5G技术广泛应用落地的基础和保障,其量值是否准确直接影响5G产业的研发、生产和质量等方面的成本,以及过程控制和生产成品的质量水平。从5G通信仪器校准测试角度阐述了5G终端、 5G承载网络测试仪器和5G大规模阵列天线的校准测试技术现状及面临的问题。
5G adopts the technologies of new network architecture,network slicing,large-scale antenna array and ultra-dense networking.It has the characteristics of large bandwidth,high reliability and low latency,and it is the direction of communication development in the future.5G test instrument is the basis and guarantee for the wide application of 5G technology.Whether its value is accurate or not directly affects the cost of R&D,production and quality as well as the quality level of process control and finished products of 5G industry.The present situation and problems of calibration and testing technology of 5G terminals,5G bearing network test instruments and 5G large-scale array antennas are described from the prospective of 5G communication instrument calibration test.
