Feasibility of RSSI based 60 GHz WLAN discovery for multi-band WLAN

Abstract

This letter proposes RSSI (Received Signal Strength Indicator) based 60 GHz WLAN discovery for multiband WLAN (Wireless LAN), which uses both 2.4/5 GHz band and 60 GHz band to achieve high transmission speed, sufficient reliability and power-saving of a multiband WLAN device. The proposed 60 GHz WLAN discovery detects 60 GHz WLAN coverage by using RSSI of 2.4/5 GHz WLAN signals. Space/time diversity is employed to improve the false detection probability of 60 GHz WLAN discovery. Ray-tracing simulation results confirm that 60 GHz WLAN discovery is feasible and space/time diversity is effective to improve the reliability of 60 GHz WLAN discovery.
