So while not necessarily part of a government public safety system, you do see it often in its conventional iteration with security firms and things like that. So mall security schools, all this sort of stuff, and they'll use it in a fixed conventional manner. So in that case, they'll register one or two or three conventional channels, which will be used for DMR. So in that case, they'll operate in the business sector, which is usually the upper side of 400 megahertz, and they'll be given a group of channels often nowhere near each other, just whatever is available. Somebody will program the radio and hope that the SWRs are reasonable. But most handhelds, like they can handle terrible SWRs because that's not uncommon to have frequency sort of all over the place. But anyway, so they'll use conventional DMR as it stands.
