Abstract

A need for measurement data for frequencies above 100 GHz has increased. In this paper, we present the measurement system for millimeter wave frequencies (30–300 GHz). It is based on Keysight PNA-X vector network analyser with frequency extenders mounted on custom built 3-axis rotation stages (both the transmitter and receiver sides). We present some initial results from measurements conducted in an office corridor. Both line-of-sight (LOS) and non-LOS (NLOS) cases are included in the measurement set-ups. The results show that in all cases the channels are sparse with clear clusters from large reflecting surfaces, such as walls and floors. The measured power levels are rather strong indicating relatively low reflection losses. While the channels were sparse, there were still typically relatively large numbers of distinguishable paths. The numbers of observable paths as well as the delay spread of the channel increase with increasing beamwidth.
LOS和NLOS办公室走廊环境中D波段信道测量的初步结果
对100 GHz以上频率的测量数据的需求有所增加。本文介绍了毫米波频率(30 - 300ghz)的测量系统。它基于Keysight PNA-X矢量网络分析仪,频率扩展器安装在定制的3轴旋转阶段(发射器和接收器两侧)。我们介绍了在办公室走廊进行的一些初步测量结果。视距(LOS)和非视距(NLOS)情况都包括在测量设置中。结果表明,在所有情况下,通道都是稀疏的,并且在墙壁和地板等大反射表面上有清晰的簇。测量的功率电平相当强,表明反射损耗相对较低。虽然通道是稀疏的,但通常仍然有相对大量的可区分路径。随着波束宽度的增加,可观测路径的数量和信道的延迟扩展都在增加。
