OK, we have a full circle of PMP450M APs on a water tank in Rockingham NC with a scattering of PMP450b clients. ABAB frequency reuse, four 10MHz PAL channels utilized in pairs for two 20MHz wide channels. One AP aims south (azimuth 180) and was booted by DPA events (East11,East12, min 95 miles away from tank) on June 8th from one-half of its usual 20MHz wide PAL channel. So it rebooted itself and set itself to a 10MHz wide channel on the remaining half that had NOT been affected by the DPA. Clients reconnected and service continued. Perfect.(ish)
The opposing AP aiming north (azimuth 0) on the same channel (3580-3600) was NOT impacted by the same event. HOWEVER, the single client off of it WAS impacted. Because it was the client end device (PMP450b) and not the AP end device, the sector did NOT reboot and adjust itself to accommodate, and the client (county historical society) was out of service all day until the series of DPA move events concluded.
I would have expected/hoped that the sector would have been able to adjust itself to accommodate the required change in order for the clients to continue operating. The frequency and duration of DPA events is quickly leading us to avoid deploying CBRS equipment, particularly when the equipment turns out to not be able to adapt as needed to continue running.
