Wi-Fi that holds a full office, a full room or a full service

Coverage is a survey, not a router in a cupboard. The room, the garden, the shop floor and the teaching space are different problems, and they fail when they are treated as one.

Guests, the till and the office do not share a network. The line that feeds them is a separate service, with a failover if the business cannot stop when one circuit stops.

We leave a map. The next access point should not be a fresh mystery.
