Automatic RF Adjustment – Auto Power

Automatic power uses a proprietary algorithm to automatically adjust the RF signal to broadcast far enough to reach wireless clients, but not so far that it interferes with RF signals broadcast by other APs.

12

Automatic RF Adjustment – Auto Channel

Channels will automatically be adjusted on any new event in the system such as an AP being added or removed, or the switch can be programmed to automatically readjust channels at certain times (i.e. 2:00am each day) of the day or upon a certain interval (i.e. every 6 hours)

2. Rogue AP or Radio interferenceChannel 48

Channel 24 Channel 48

Channel 36

3. Changes toChannel 18

Channel 54

1. When first time implementing APs, the System selects different channels forAPs at random to avoid interference

13

Automatic RF Adjustment - Self-Healing Network

Fail-Safe• When a Managed AP is powered down, the power of its neighboring AP(s) managed by

the same switch is immediately increased by 20%.• The power level will adjust again every pre-configured Interval by sensing neighboring

AP power status.

FailedIncrease 20% of power!
