Carriers are retiring copper networks. Alarm panels, elevator emergency phones, fire panels, fax machines, postage meters, and old point-of-sale terminals often depend on analog lines nobody has inventoried. The first sign is often a failed inspection or a dead elevator phone.

Unlimited means no fixed cutoff on how much you use, not unlimited speed or priority. When a busy cell runs out of capacity, deprioritization and video limits are the plan working as written.

When desk phones become softphones and staff work from home, an emergency call can go out with the location of a building the caller is not in. Location discovery, user-updated addresses, and testing how emergency calls actually route from home, hotel, and office before someone needs it.

Energy-efficient glass, concrete, and steel can make modern buildings hard for mobile signals to penetrate. Carriers no longer pay for in-building coverage systems the way they once did, and some building codes require radio coverage for emergency responders. If staff rely on mobile phones and there are no desk phones, indoor coverage is part of the fit-out budget, the lease negotiation, and the move date.

Your desk is six feet from the router. Wi-Fi is shared, half-duplex airtime; a switched Ethernet port is a dedicated full-duplex link. A ten-dollar cable often beats a new router for a desk that never moves.

A vendor's weekend cutover plan for a 1,500-agent contact center ignores the recording platform, workforce management feed, CTI middleware, IVR media server, fax lines, and carrier port schedules. Here is how to stage the move.

5G is the fifth generation of mobile standards: a radio interface, a set of licensed bands and the same old towers, permits, backhaul and exposure limits. The most suspicious thing about it is the coverage map.
