The End of 3G Cellular Monitoring Transmission and What it Means for Your Alarm System

By: Desirae Carroll on December 20,2021 01:37:37 PM

The upcoming discontinuation of the AT&T 3G network will affect security and fire alarm monitoring systems across the country. At the beginning of 2022 alarm monitoring communicators will have to transmit signals via the 5G network. What does this mean for you? Depending on the type of monitoring equipment you have, you may be forced to replace your existing alarm communicator in order to continue monitoring your fire or security system.

The sunset (or discontinuation) of the 3G network is scheduled to take place on February 22, 2022. In short, this means that monitoring equipment utilizing the 3G technology will NOT be able to communicate with the Central Monitoring Station and thus systems utilizing 3G technology will not be monitored.

In order to avoid disruption in monitoring service, have your alarm contractor verify the type of alarm monitoring technology you currently have installed and determine if it will work on the 5G network.

A replacement communicator that utilizes the 4G or 5G network will be required to continue your monitoring service.
