IEEE 802.11ay: technical capabilities of a millimeter wave technology designed to address the insatiable desire for wireless data capacity

Carlos Cordeiro


While local and personal wireless technologies have greatly evolved in the last few years, new applications and continued usage growth demand greater throughput and reliability with lower latencies. Augmented reality and virtual reality applications, mobile offloading, high-bandwidth connectivity to multiple TV and monitor displays, and indoor and outdoor wireless backhaul are just a few applications that require new wireless technologies that can exceed what current wired and wireless interfaces can offer. To meet the demanding requirements of such diverse applications, the IEEE 802.11 Task Group ay (802.11ay) is defining PHY and MAC amendments to the 802.11 standard that enable Wi-Fi devices to achieve 100 Gbps using the unlicensed millimeter wave (60 GHz) band at comparable ranges to today’s commercial 60 GHz devices based on the 802.11ad standard. In this talk, our main goal is to identify and describe the main PHY and MAC elements present in the current IEEE 802.11ay draft standard, with a focus on technical capabilities that enhance capacity including MIMO, channel bonding, and enhanced beamforming training. For each of these areas, we discuss how their design is impacted by millimeter wave radio propagation characteristics and analyze their performance.
