I’m a heavy user of the 5 GHz band at home for Wi-Fi, as I’m not inclined to drill half a dozen of holes through several rooms to get ‘the Internet’ and high speed connectivity from my local servers (i.e. ‘the private cloud’) to my workspace. My biggest enemy: The required radar detection and subsequent downgrade of the Wi-Fi channel to the lowest 80 MHz of the band.
So what’s the problem with using the lower part of the 5 GHz band? In practice, whenever radar is supposedly detected, my link rate drops from almost 800 Mbit/s to 500 Mbit/s for a while, as transmit power is limited in that part. Also I’m limited to an 80 MHz channel.
