As Qualcomm AFC service was done, the grace period did not work on 2 units, one was a 4625 we had for a link and an epmp4600 AP, these 2 units where expired and there was no backup, we had 236 customers off line for 12 hours, Cambium needs to have some sort of back up or something in the firmware where you can override the system for at least a day or 2 for when Qualcomm goes down. this in my opinion needs to be looked at as we are planning to move another 100 customers on to the 6 GHz
