Pathloss Study for 61 GHZ Wave D2D Communications in Indoor Environment

The present paper deals with device-to-device (D2D) communication for millimeter wave and its performance in indoor wireless communication application. The 61 GHz Industrial Scientific and Medical band is considered for verification of link visibility and path loss behaviour. Line-of-sight (LOS) blockage is the major problem in indoor wireless communication as the signal gets attenuated when the LOS path comes across any obstacle. To overcome this problem, directional antennas are used through which the direction of propagation can be diverted. While selecting such non-line-of-sight (NLOS) path, the transmission path must offer relatively lesser attenuation. The output of this work would be useful for identification of NLOS paths by using beam switching mechanism for D2D communication.
