IN APRIL 2020, the US FCC voted to allow unlicensed wireless LANs to operate in the 6 GHz band, covering frequencies from 5925 MHz to 7125 MHz. Other regulatory domains have since announced their own plans or intention to adopt rules for their particular country or region. The resulting 1200 MHz is over double the best-case scenario for wireless LAN networks in the past 25 years. Make the most of this opportunity by designing optimal use of the available frequency. Understanding the details will help to get the design right the first time.
