Abstract

This article investigates on developing a methodology for statistical channel modeling for 60 GHz Wireless Local Area Network (WLAN) system. The most significant characteristics of indoor 60 GHz propagation channels such as large scale propagation path loss, quasi-optical propagation nature, reflection, diffraction, shadowing effect, clustering nature of the channel, effective impact of polarization and necessity of steerable directional antennas are taken into account. This research work has focused on modeling of the 60 GHz WLAN system to estimate the RMS delay spread (RDS) considering both directional and non-directional antennas for residential indoor environment. RDS is a measure of communication channel delay and estimates fading characteristics. Multipath effects and channel deep-fade can be alleviated by minimizing the channel RDS. This research work analyses the RDS characteristics of a living room environment considering two different indoor channel model approaches. Here, the IEEE 802.11ad living room channel model and the Saleh-Valenzuela       (S-V) model are considered while developing channel impulse response as well as RDS. The investigations show that highly directional steerable antennas can effectively reduce the channel delay spread. A comparative study between the IEEE 802.11ad and the S-V models has also been performed in the later section.
