Recently, the unlicensed 60 GHz millimeter wave (mmWave) band has drawn attention as a promising solution for enabling future multi-Gbps wireless local area networks (WLANs). IEEE 802.11 ad (WiGig) standard was developed for 60 GHz WLANs, where directional transmission is utilized to compensate severe propagation losses in mmWave bands. Due to mmWave signals propagation limitations and its high vulnerability to ... Read more
