Will we have to go to every connected CPE and replace the SIM card? ---

Terry, No, the SIM cards are registered with the EPC. The eNodeB’s are the hardware bridge between the two. ---

Do you have a link where I can listen/watch the webcast? I missed the first part of it. Terry Darst President ANTS-Technology Inc. 1105 E.

I think, in the case of a PCI lock, you can just edit the PCI value on the new base station to match the PCI value of the old one, which would allow all UE’s to re-attach without revisiting each UE. Casey ---

Can the CPEs see more than eNB? If so, and you are using PCI lock, @Jesse pointed out to me yesterday that you can add multiple PCI locks on each CPE, thereby still having auto failover in the event of an eNB loss.
