How does an AP perform band steering to encourage clients to use 5 GHz?
The client devices that connect to your network include a mix of dual-band 802.11n and 802.11ac, single-band 802.11b/g/n, and some 802.11a/g/n. Your access points are configured with the same SSID on both the 2.4 and 5 GHz bands. The APs are also configured to prioritize client connectivity to 5 GHz....
What is the correct name of this process, according to the IEEE 802.11-2012 standard?
Based on RSSI metrics, concentric zones of variable data rate coverage exist around an access point due to the upshifting and downshifting of client stations between data rates. What is the correct name of this process, according to the IEEE 802.11-2012 standard?A . Dynamic rate shiftingB . Dynamic rate switchingC...
