3G/LTE/5G network upgrades in San Jose (alarm systems)
My alarm system at home has an older 3G GSM cell radio with AT&T service that I got in early 2015 (I own the equipment rather than leasing). My alarm company emailed me to schedule an upgrade to an LTE communicator and they said that it is required because AT&T is currently converting their 3G network to LTE.
I also said that it looks like AT&T already has 5G in some parts of San Jose, and that since my current unit will work for another 2+ years, I would rather wait and upgrade to a 5G communicator rather than an already-obsolete LTE one.
They responded and said that they just talked to the Resideo rep (who makes the communicators) and they said the following:
"They have no plans for a 5g unit in the works. Their next plan of action that they have is a completely redesigned alarm panel that will have hot swappable communicators for whatever network is designed by that time"
"The LTE model is supposed to be in service until 2029."
"5GE (evolution) is what you were thinking of, that is actually a marketing ploy by AT&T, it is not a true 5G from what we have been told."
"If the towers change that serves your location to the new LTE, there is a risk that the network you are on will lose its stability. This is known as “carving into the network”, we have been having units drop every week since they started upgrading the towers. If your communicator loses connectivity, we will contact you to let you know. We are typically booked a few weeks out due to the amount of upgrades we are doing."
