Which Aruba technology uses 6 GHz band spectrum introduced in Wi-Fi 6E to deliver additional non-overlapping channels?

Accepted Answer

Wi-Fi 6E extending 802.11ax into the 6 GHz band

Answer

Wi-Fi 6E extends the 802.11ax standard into the newly opened 6 GHz band, providing up to 1,200 MHz of additional spectrum with 59 non-overlapping 20 MHz channels in the US.

Question 2

In Aruba's Adaptive Radio Management (ARM), what does 'Band Steering' accomplish?

Accepted Answer

Moves clients from 2.4 GHz to 5 GHz to reduce congestion

Answer

Band Steering nudges dual-band capable clients toward the less congested 5 GHz band by withholding probe responses on 2.4 GHz until thresholds are met.
