Idea: Support for 4G/Out of Band connectivity #3

A common feature in many modern burglar alarm systems is 4G connectivity. Because if you lose your primary connection, either due to power loss or an upstream fiber cut you won't receive any alerts from your panel, nor will you be able to manage it remotely. Cellular networks on the other hand very rarely go down.

New low bandwidth cellular technologies like NB-IoT and LTE Cat-M allows connectivity to be added inexpensively. With a module I bought off Aliexpress and a prepaid SIM card I have a backup connection for only a few dollars a month. Even better these modules can send out text messages directly with a few AT commands.

I think this would be a useful feature.

Another option, depending on where one is, would be something like LoRA and The Things Network.

I concur these are interesting questions. 4g connectivity provides tcp/ip I believe. So one could run OSDP over TCP/IP using a cell modem and get the fallback capability you suggest. LoRA and other creatures do not AFAIK directly provide a connection mechanism. I think you would have to use the "OSDP Data Model" on top of other mechanisms.
