Most sites still have 802.11b present, with 802.11n seen slightly more perhaps due to low cost APs not supporting 5GHz. Wi-Fi 6 (802.11ax) appears to be enabled in both bands equally, but is only starting to be widely deployed. In 5GHz, 802.11g was present in 51% of the BSSIDs followed by 802.11n. Since a BSSID beacons all of its types up to its maximum capability, the presence of 38% .11b indicates some .11g APs have .11b turned off.
