Abstract
The next generation Wireless Local area network IEEE802.11ay (Wi-Fi) is an enhancement of 802.11ad in unlicensed 60 GHz mm Wave frequency band. The millimeter (mm) Wave frequency band 6–100 GHz range provides more BW to achieve higher data rate but it supports only 50 to 200 m short range. The 802.11ay leverages the latest development in MIMO (Multi-input multi-output antennas), channel bonding, and enhanced beam formation to minimize spectral efficiency and provide better quality of service for large number of user stations. This upgrade offers significant speed and range improvements. Beam forming technology has been introduced in 60 GHz mm wave frequency band to compensate high path losses, and oxygen absorbing some mm wave frequencies signal. Beam formation can be effectively utilized in mm wave frequency band. It aims to generate different beams for different user stations using an array of antennas elements at the Access Point (AP) to communicate between different user stations. The effective beams undergo minimum power loss and co-channel interferences, and are aimed to direct towards the user station. In this paper we have simulated different types of arrays and analyzed different beam contours that are generated from the arrays of antennas to transmit to the user station.
