This research work targets to address the needs of next generation wireless technology for Wireless Local Area Networks (WLAN) and Wireless Personal Area Networks (WPAN) including multimedia equipment, utilizing short-range Gigabit Radios at 60 GHz. The issues involved in planning and deployment of wireless communications operating at 60 GHz are examined in this paper by analyzing the radio channel propagation characteristics in typical indoor environments such as Narrow Straight Corridor (NSC) and Class Room (CR). This study includes several onsite measurements using 60 GHz transmitter/receiver modules and modeling of similar environments using full 3-D Ray-tracing simulations of Remcom’s Wireless InSite and XGtd. It is observed from the performed analysis that the architectural design and dimensions of the indoor environments play a vital role in the Received Signal Strength (RSS) where the observed Path Loss Exponent (PLE) value is found to be 2.11 to 2.25 for NSC and 1.92 to 2.13 for CR within an operating space of 10 m. It is also witnessed that the maximum Specific Absorption Rate (SAR) value at the receiver is 0.2*10-05 W/kg for 1 gm of brain tissue for WLAN/WPANs at 60 GHz. © 2014 IAMOT.
