How much network does this site need?

Work it out two ways and take the higher: by floor area (an access point covers roughly 100 to 230 square metres indoors, depending on the walls) and by capacity (about 25 to 40 busy devices each). Busy offices are usually decided by capacity, large quiet ones by coverage.

As a rough guide, about 2,500 sq ft in open plan, 1,700 sq ft with partitions, and 1,100 sq ft with brick or concrete walls, on 5 GHz. 6 GHz reaches less far, so a design for 6 GHz everywhere needs more.

Yes, since 20 January 2026, for low-power indoor and very-low-power outdoor use in the lower 6 GHz band (5925 to 6425 MHz), licence-exempt. Wi-Fi 6E and Wi-Fi 7 access points can use it.

Roughly 1 to 2.5 Mbps for each person online at the busiest time, more with a lot of video calls. Take two lines from different providers, each able to carry most of the load alone.

Plan about 30 W for each tri-band access point, and check the model: some Wi-Fi 7 access points need 802.3bt to run all three bands at full power.

No. It is a planning estimate for budgets. Walls, ceilings and neighbouring networks change the numbers, so a survey should confirm the positions before anything is ordered.
