3G Sunset On The Horizon

Silent Guard • May 10, 2021


Cell phone companies announced that the shutdown of third-generation, or "3G," wireless network will be complete by the end of 2022. This shutdown will not occur all at once. It will appear sporadically across the country and on January 1, 2023, the 3G wireless network will cease to exist. 4G service is becoming the default for most devices that are released into the marketplace, for the simple reason that 4G is both faster and more efficient. And now, as the 5G build-out begins, it is getting more and more difficult for the carriers to justify keeping their 3G services operations.


Why does the 3G Sunset affect alarm systems?

Wireless alarm systems communicate via cellular networks like the 3G and 4G networks. Many wireless alarm systems were installed with a 3G compatible GSM (Global System for Mobile Communication) device that can only communicate via the 3G wireless network. Therefore, when the 3G network ceases to exist on January 1, 2023, these alarm systems will no longer be able to communicate alarm signals.
