- If you lose power, you lose GPS lock. Don't know if it's policy or fed law, but these extenders won't work without a GPS signal for 911 calls, at least ours didn't.
It's not for 911 calls. It's not policy, and it's not law. It's engineering. It's for timing. Cellular base stations (which is what that thing really is) require a very precise timing signal to synchronize with the network. The GPS supplies that time signal.
The Wilson is a good choice. That company has been around a long time and builds a quality unit.

Makes sense. The first thing we did to update the US Early Warning Radars to the GMD UEWR standard for the GMD program was to install two GPS antennas on the radar buildings. No it wasn't to ensure we knew exactly where the building was (although that is useful), it's to provide the exacting timing signals for missile intercepts.
Now, having said that, you proved my point: You need three things for a cell network extender to work: the extender, the internet and GPS signal. Anyone one of them down, you're screwed for cell phone signals.
