Millimeter-Wave Indoor Channel Characteristics in$V$and$E$Bands

摘要

This paper presents a benchmarking analysis of wideband channel characteristics in two indoor environments in the 59-65 and 80.5-86.5 GHz bands. Measurements were carried out by performing mechanical steering of directive antennas at both the transmitter and receiver sides. Omnidirectional power delay profiles were obtained from directional measurements and multipath components are subsequently estimated. The comparison of large-scale parameters such as the path loss, the delay, and angular spread is provided. Multipath clustering was investigated for both the bands and the environments, and wideband channel model parameters are provided. Based on measurement results, commonness between paths in different bands was analyzed, highlighting the presence of some well-identified paths plus frequency-dependent ones.
