摘要

预计小型蜂窝将承载5G总流量的一半以上,从而导致无线回程流量的大幅增加。为了成功设计和部署毫米波回程系统,必须评估不同场景下的性能,以及安装在低人类高度的链路。我们报告了最近的5G e波段回程系统测量活动,重点关注车辆穿过和行人沿着视线行走的影响,以及室外到室内的穿透损失。由于车顶和人在与无线电视距相同或略低的高度移动,它们对无线电信号的影响很明显,但不是有害的。通过引入高度的微小变化,可以将影响从12 dB减少到3.4 dB。现代玻璃的穿透损耗范围为5db ~ 39db。

5G E-band backhaul system evaluations: Focus on moving objects and outdoor to indoor transmission
It is expected that small cells will carry more than half of the total traffic in 5G, resulting in a huge increase of wireless backhaul traffic. To successfully design and deploy the mmW backhaul system, it is essential to evaluate the performance in different scenarios, also links installed in low human height-level elevations. We report a recent 5G E-band backhaul system measurement campaign focusing on the effects of vehicles passing across and pedestrian walking along the line-of-sight, and outdoor to indoor penetration loss. With the car roofs and humans moving in the same height or a bit lower than the radio LOS, their impact on the radio signal is clearly seen but is not detrimental. By introducing small changes in height, the impact can be reduced from 12 dB to 3.4 dB. The range of penetration losses of modern glass is from 5 dB to 39 dB.
