Transition to LTE means many security systems will no longer work properly

Every day new technology is introduced, and products and services that were state-of-the-art only a short time ago are replaced with new, more robust options. One of these very significant technological shifts is occurring right now. It’s called the 3G Sunset, and will very likely impact whether or not your alarm system is fully operational. The 3G Sunset date is quickly approaching!

Watch this short video for a brief explanation of how the 3G Sunset may impact your security and steps to take to ensure you are protected ahead of the 3G to LTE transition.

What is the 3G Sunset?

In short, the 3G Sunset means that cellular providers are in the process of upgrading their networks from 3G to LTE (Long-Term Evolution) communications. As they do this, they are turning off (“sunsetting”) network communications via 3G.

This transition is happening now, although information from the carriers about actual transition dates for specific areas has not been very specific. That means your security could be adversely affected – at any time – without warning.

Here in the Temecula Valley, we predominantly need to be concerned with the dates for the AT&T 3G Sunset, and the Verizon 3G Sunset.


Cellular communications networks are upgraded about every 10 years. The move to LTE is a major technological leap forward. (Click on the graphic for a larger image.)

How Will the 3G Sunset Affect My Security System?

Older devices that are part of the Internet of Things (IoT), like smartphones and even security systems, run on this 3G network. When companies cut this service off, these devices may no longer function properly.

In short, once 3G services are discontinued, your alarm system may no longer communicate with the monitoring center in an emergency.

Security systems that rely on the 3G network to communicate during an emergency will malfunction without an upgrade to LTE.

How Will LTE Improve My Security?

First and foremost the upgrade will ensure your security system is properly working, no matter when the transition from 3G to LTE occurs in your area.

LTE is also a huge technological leap forward. After the 3G Sunset, alarm systems operating on the LTE network will be able to communicate much faster and more reliably than they were previously, greatly improving and enhancing your security.

Your current security company should have already contacted you regarding your situation with respect to the 3G Sunset. If not, contact us right away to determine if your security system requires an LTE upgrade to continue functioning properly.

What Should I Do to Prepare before the 3G Sunset?

The AT&T Sunset date is slated for February 2022, and the Verizon 3G Sunset is scheduled to occur on December 31, 2022.
