I discovered from tech support that if you have managed access turned on people not on the whitelist will standby on your network extender but when they place calls will be handed off to the nearest cell tower if available. If not available then only 1 unauthorized user can take up one channel and everyone else will just be directed to nearest tower or get all circuits are busy recording.
I recently had the power boosted on my network extender by tech support because I was having issues with phone calls handing off to the cell tower whenever I am upstairs and this leads to call dropping. Now I can get 3-4 bars upstairs with the network extender before it was boosted I only got 1 bar. The downside of the power boost is that I live across the street from a hospital emergency room and my network extender extends coverage to the waiting room. However, I have not noticed increased usage on my network extender.
I am experiencing these 4 issues now though:
#1 With location aware apps like Maps, Facebook, Foursquare it will display my location for Santa Clarita, CA or Saugus, CA even though I am in Monterey Park, CA no where near Santa Clarita.
#2 Other issue is when I am in a call there is an audible clicking soundheard every few seconds. Sometimes it is just one click other times it is a succession of clicks. It sounds like someone picked up the extension of an landline telephone. The voice quality is unaffected though just the annoying clicks.
#3 Final issue is on phones running the Android operating system if I dial numbers with +1 (area code) I get an error message from Verizon. This only happens when I am connected via network extender.
#4 If I turn LTE off and wifi off the battery seems to drain pretty quickly when on 3G. If I turn LTE on and wifi off the battery drains quickly as well but not as fast if LTE turn off. I just leave LTE on and connect to my wifi and the battery drain issue is not there.
