Increased Demands on Wi-Fi Posing Difficult Challenges 


Over the next decade, Wi-Fi faces a number of difficult challenges. Key among them are the growing demands being placed upon Wi-Fi networks leading to increased congestion, performance limitations, and reduced quality of service. New Wi-Fi standards such as 802.11ax are helping to address some of these challenges; however, increasingly there is an acknowledgement that the existing unlicensed spectrum available for Wi-Fi will be insufficient in addressing the future needs of the Wi-Fi ecosystem. Last year, leading companies invested in the Wi-Fi ecosystem including the likes of Broadcom, Cypress, Intel, Cisco, MediaTek, Google, Apple, and Facebook came together to press the U.S. Federal Communications Commission (FCC) on the need for unlicensed spectrum in the 6 GHz band (5,925 to 7,125 MHz) to be opened up and be utilized by Wi-Fi technologies. In anticipation of regulatory action, the IEEE 802.11ax Task Group amended the Project Authorization Request (PAR) for 802.11ax to expand the scope of the covered frequency bands from 6 GHz to 7.125 …
