为了研究无线航空电子内部通信（WAIC）设备和5G移动的通信设备之间的频谱共享情况，测量了直升机在4.2 ~ 4.4 GHz频率范围内的无线电高度表干扰路径损耗（IPL）。WAIC设备和5G移动的通信设备在相同和相邻的频带中操作。首先，概述了用于IPL测量的直升机。然后讨论了基于标准文件的测量设置。最后，舱内和舱外的最小IPL值分别为49.1 dB和55.1 dB。
Radio altimeter interference path loss (IPL) of a helicopter, which operates between 4.2 and 4.4 GHz, is measured to investigate the spectrum sharing condition with Wireless Avionics Intra-Communication (WAIC) devices and 5G mobile communication devices. WAIC devices and 5G mobile communication devices operate in the same and adjacent frequency bands. Firstly, an overview of the helicopter used for IPL measurement is provided. The measurement setup based on the standard document is then discussed. Finally, the minimum IPL value inside and outside of the cabin is 49.1 dB and 55.1 dB, respectively.
