Idea from Eric Cronin at Lakeland Regional Hospital:

"

Do you know if I can broadcast to a location and any users within range of that location (access point) could get the message.

Scenario:

There is an emergency in the lobby and there are offices within range of the access point in the lobby. Can I say something like “broadcast to Lobby”?

The trick would be able to reach anyone within range regardless of the group they belong to."
