摘要

This study investigates the coverage area and channel bonding performance of millimeter-wave (mmWave) Multiple Input-Multiple Output (MIMO) systems, with a specific focus on 60 GHz Wireless Local Area Network (WLAN) communications under both line-of-sight (LOS) and non-line-of-sight (NLOS) conditions. As the demand for high-speed wireless data transmission increases, this research aims to enhance bandwidth efficiency through effective channel bonding techniques. Our analysis covers three frequency bands: 2.4 GHz (IEEE 802.11n), 5 GHz (IEEE 802.11ac), and 60 GHz (IEEE 802.11ay), utilizing a comprehensive path loss model. The results demonstrate that channel bonding capacity in LOS scenarios significantly exceeds that in NLOS conditions. Notably, the 60 GHz 16 × 16 MIMO system achieves a maximum bandwidth of 12.96 GHz, resulting in peak data rates of 118.89 Gbps for LOS and 110.36 Gbps for NLOS. The coverage areas are quantified as 9.75 m for LOS and 4.8 m for NLOS in the 60 GHz band. These findings underscore the critical trade-offs between bandwidth and coverage in mmWave systems, providing valuable insights for optimizing future high-speed wireless communication technologies. This research contributes to the growing body of literature on mmWave communications and addresses the pressing need for efficient bandwidth utilization in modern wireless networks.
