摘要：

首先，从未来移动通信系统频谱需求与当前低频段频率规划总量的差距，论述向高频段寻找可用频率资源的必然趋势。然后，从高频段频率规划、标准化进展等方面，对全球高频段无线通信的发展现状进行阐述，并通过分析高频段特性，对其传播特征进行了归纳。最后，分别从潜在可用频段、无线传输技术、组网技术以及射频技术4个方面提出了未来高频段无线通信的优势和挑战。

Abstract:

Firstly, the inevitable trend was discussed that the available spectrum of the future mobile communication systems would be found in the higher frequency band, since the gap between the future spectrum requirements and the current planned total spectrum in the low-band was considerable. Then the status of the development of global hig h frequency wireless communications were introduced, in terms of high frequency band planning, related standardization and organization activities. Next, the propagation characteristics of high frequency bands were analyzed and summarized. Finally, the advantages and challenges of future high-band communications were proposed from potential available bands, transmission technologies, networking technologies, and radio frequency technologies.

Key words: spectrum requirement, high frequency band, wireless communication, 5G
