What's the difference between a 2g and 4g system?

Last Updated: 11/08/2013

2G security systems are typically older and will stop working on a specific date. Most recent systems use 4G communicators, and they will work in perpetuity.

All of Honeywell's cellular alarm communicators use the AT&T network.  A sunset date has been established by AT&T, which means on January 1st, 2017, all 2G communicators will stop working.  The 4G communicators will continue working in perpetuity, until otherwise specified by the network provider.

Modular systems, like the Vista 20P and 21iP, and the L3000 and L5100, can be upgraded.  The L5000 does not have a 4G communicator.  All Vista Panels can be outfitted with 4G communicators, like the GSMV4G and the GSMX4G, except for the Vista 21iP.  The GSM4G communicator is designed specifically to work with the Vista 21iP.  The GSMVLP5-4G is compatible with the L5100, and the GSMVLP4G is compatible with the L3000.
