Wi-Fi 6 innovations in 6 GHz are integral to 5G success

In 2022, 56% of new devices 11ax

- 11% of new devices in 2019 (~150-250 Mu) will be Wi-Fi 6 enabled

- Cisco asserts Wi-Fi 6 is important for 5G era driving increased offload from cellular networks

- 71% data offload to Wi-Fi for 5G networks; total data offload to Wi-Fi increases from 74% to 79% in 2022

To unlock the full benefits of the next generation of Wi-Fi we need more spectrum—6 GHz is the best bet

● Freeing this band for unlicensed would create a “Wi-Fi Superhighway,” critical to carrying the traffic expected with 5Gservices

● The 6 GHz band could enable up to seven 160 MHz channels, which would provide superfast coverage

● If the NPRM is approved, the 6 GHz band could open up to 1,200 MHz of more spectrum for Wi-Fi
