2G Sunset and Your Alarm System

2G Sunset.

How will the 2G Sunset affect your Alarm System?

Technology marches forward.  Similar to the 2008 sunset of analog cellular coverage, the end of 2G cellular service is set for 2017.  What is this about, and will it affect my alarm system’s cellular communication for monitoring services?

What is the AT&T 2G Sunset?

AT&T NetworkIn August of 2012, AT&T Inc. announced that the shutdown of its second-generation, or “2G,” wireless network will be complete by the end of 2016. This shutdown will not occur all at once. It will appear sporadically across the country and on January 1, 2017, the 2G wireless network will cease to exist.

Why is AT&T shutting down the 2G wireless network?

Data use on wireless networks is increasing as more and more people adopt smartphones. AT&T realizes that shutting down the 2G network and using that space for 3G and 4G networks will drastically increase data capacity and speed on the newer networks.

Why does the 2G Sunset affect alarm systems?

Wireless alarm systems communicate via cellular networks like the 2G, 3G and 4G networks. Many wireless alarm systems were installed with a 2G compatible GSM (Global System for Mobile Communication) device that can only communicate via the 2G wireless network. Therefore, when the 2G network ceases to exist on January 1, 2017, these alarm systems will no longer be able to communicate alarm signals.
