AirOS¶

http://www.ubnt.com/wiki/RF_Compliance

For example, if you select 5805 MHz (40 MHz channel) and Below, the radio will use (5775 to 5795 MHz) + (5795 to 5815 MHz),
but if you select 5805 MHz (40 MHz channel) and Above, the radio will use (5795 to 5815 MHz) + (5815 to 5835 MHz).

AirView test¶

Lab on table same room compliance mode 5.5
- one NSM5 AP WDS
- one LocoM5 STA WDS 1 meter from the NSM5
- one NBM5 head (without dish) right in between Loco and NS running AirView

Steps for each graph

1. associate NS and Loco with new frequency and width
2. clear airview
3. launch 300 second iperf client between netbook behind NSM5 to iperf server on locoM5
4. after iperf is done save airview screenshot
5. go back to step 1
