And look at the in-service SA features now offered on the latest RocketM5AC-Lite and upcoming mimosa products.. They can perform AP SA’s while remaining in service by listening during spare RX cycles.. no need to take down the AP or worse an entire tower.. everything pays attention to sync and you keep in service.

But yeah, my thought was close to yours. We have some towers only a mile or two apart and the SMs will definitely pick them up. This is one reason why I mentioned AP mode background SA. Schedule an Rx slot for background SA and give me a 1 or 5 minute average of my current channel. This is pretty much what happens with LBT now anyway.

Since it is not paying attention to the sync pulses, but just coordinating running an AP spectrum scan with the SMs you are still going to see a bunch of bogus energy from co-located access points. In order to do this in a way where you can really see what the spectrum looks like, the AP should only perform SA during its appointed receive windows and not during the TX windows of other co-located equipment. Another side effect for those of us running fancy beam forming antenna arrays is we can never use ‘Sector SA’ at all, since it is listening during the TX windows of other access points connected to the beam former and getting high RF levels shoved into its RX side.

Cambium is writing a paper on how to adjust the radios to best deal with other synch sources, although the radios will still work together without adjustment with some impact to throughput. We look forward to you feedback on this release either in this forum or at: http://community.cambiumnetworks.com/t5/PMP-Beta/bd-p/forums_pmp_beta Best, Cambium Jonathan
