Measurements reveal the effects of bandwidth on channel characteristics for 5G and B5G systems, indicating significant differences in propagation patterns.
This paper presents wideband indoor channel measurements in three of the millimeter wave (mmWave) bands for the fifth generation (5G) and beyond 5G (B5G) wireless systems. Measurements were conducted at the Ka‐band (36–41 GHz) and V‐band (50–75 GHz) in office and factory/industrial environments, using Durham University's custom‐designed channel sounder. Recently, several channel measurements at different mmWave bands have been reported in various indoor environments. However, few studies have explored the impact of the processing bandwidth (BW) on the estimated channel parameters. Therefore, the aim of this paper is to investigate the effects of the analysis BW on different propagation channel characteristics, such as power delay profile, root mean square delay spread, Rician K‐factor, coherence BW (), and path loss. These wideband channel parameters are measured and estimated with a BW of 0.5, 1, 1.5, and 2 GHz. The results are presented for both line‐of‐sight and non‐line‐of‐sight scenarios.
