Outdoor 6 GHz is turning up in tenders before anyone has costed AFC

Requirements for outdoor 6 GHz coverage — courtyards, loading yards, stadium concourses — are appearing in tender documents with increasing frequency, usually as one line among many.

Outdoor 6 GHz means Standard Power, and Standard Power means Automated Frequency Coordination. That is not a setting.

What AFC actually requires

  • Accurate geolocation for every access point, either from GPS or from a surveyed coordinate someone is accountable for. Geolocation uncertainty is an input to the calculation: imprecise coordinates produce a larger exclusion zone and fewer available channels.
  • Antenna height above ground level, recorded per device.
  • A daily re-query to the AFC system, with the returned channel list and power limits applied.
  • A defined fallback when a lookup fails or expires — the access point must drop to Low Power Indoor behaviour or stop transmitting on affected channels.
  • Monitoring of lookup status, because a silent AFC failure looks exactly like a coverage complaint.

Channel availability varies by location. Two access points at opposite ends of the same campus can legitimately receive different channel lists, which makes the outdoor channel plan a per-device output rather than a design-time decision.

What to put in the tender

If outdoor 6 GHz is in scope, ask suppliers directly: which access points in the design operate at Standard Power, which AFC provider is used, how are coordinates captured and verified, what is the fallback behaviour, and how is lookup status monitored.

A supplier who answers that fluently has done it. One who treats it as a firmware setting has not.

Our take

The pattern here is familiar from the early days of DFS: a regulatory mechanism that is genuinely well designed gets treated as an implementation detail until someone's coverage disappears.

Our view is that outdoor 6 GHz is worth having — the spectrum is clean and the capacity is real — but that it should be scoped as its own workstream with a named owner, not as a line item under "outdoor coverage". The organisations that will have trouble are the ones that specified it without asking the five questions above.

If you are writing the RFP, our procurement guide has the clause language.

6 GHz has quietly won the laptop, and lost the meeting room

Client support for 6 GHz is no longer the blocker in a modern estate. Access point placement is — and most organisations refreshing to Wi-Fi 6E are reusing positions surveyed for 5 GHz.
