Proactive Spectrum Manager

Proactive Spectrum Manager, designed for single channel deployment, takes a

top-level view into the channel spectrum, then recommends the best channels) for

network operation. The PSM dashboard presents a goodness value for all channels and

recommended channels of operation for the network using a chart with green (good)

and red (don’t use) bars.

Configure Proactive Dashboard Manager Using the Web UI

Use the dashboard to see the channel goodness over the spectrum and best available

channels for 20MHz or channel-bonded (40MHz) operation on the 2.4 and 5GHz bands.

The spectrum shows bar chart goodness values for all 20MHz and 40MHz channels. The

higher the bar, the better the channel is. If the color of the bar is grey, no observation

on that channel has taken place.

You have two PSM options, View and Evaluate.

View is enabled on all channels by default. View mode monitors interference, such

as rogues, and displays recommendations for channel use. If you see solid green

bands on every channel in the charts, either only View is enabled or Evaluate is also

enabled and there are no rogues on any channels.

Evaluate is disabled on all channels by default. If you enable Evaluate mode on the

channels, then PSM will manage the use of those channels by moving devices away

from channels with a specified amount of rogue activity. To enable Evaluate:

1. Click Monitor > Dashboard > Spectrum.

2. Click Evaluate at the top of the screen.

Optionally, select one of the options from the Evaluate drop-down list:

View turns on rogue detection, does an immediate scan, turns off rogue

detection, and then displays the results.

One Time Adapt turns on rogue detection, does a scan, turns off rogue detection,

and then moves stations to recommended channels immediately

Periodic Adapt repeats at the interval you set in the minutes value. Every x

minutes, it turns on rogue detection, does a scan, turns off rogue detection, and

then moves stations to recommended channels immediately.

3. Optionally change the Evaluation Time from 120 seconds to a value of 5 - 300

seconds. Evaluation affects rogue scanning (turns it on for Evaluation Time

seconds) and optionally changes channels.

4. Optionally change the Threshold from 25 to a value of 1 - 100 rogues. Threshold

indicates a delta in goodness value between current and recommended channel

that triggers a change of channel. Non-zero threshold applies to periodic

adaptation.
