Centre frequencies and rules for every band Wi-Fi uses: 2.4 GHz channels 1-13 (only 1/6/11 are non-overlapping at 20 MHz), 5 GHz U-NII sub-bands with DFS, 6 GHz (Wi-Fi 6E) at 5925-7125 MHz, and Wi-Fi 7's 320 MHz channels.
| Channel | Centre (MHz) | Channel | Centre (MHz) | Channel | Centre (MHz) |
|---|---|---|---|---|---|
| 1 | 2412 | 6 | 2437 | 11 | 2462 |
| 2 | 2417 | 7 | 2442 | 12 | 2467 |
| 3 | 2422 | 8 | 2447 | 13 | 2472 |
| 4 | 2427 | 9 | 2452 | 14 | 2484 (Japan, 802.11b only) |
| 5 | 2432 | 10 | 2457 |
Key points:
| U-NII band | Channels (20 MHz) | Frequency range | DFS required |
|---|---|---|---|
| U-NII-1 | 36, 40, 44, 48 | 5150–5250 MHz | No |
| U-NII-2A | 52, 56, 60, 64 | 5250–5350 MHz | Yes |
| U-NII-2C (Extended) | 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144 | 5470–5725 MHz | Yes |
| U-NII-3 | 149, 153, 157, 161, 165 | 5725–5850 MHz | No |
DFS (Dynamic Frequency Selection) exists because these sub-bands are shared with radar:
Regional availability: USA 36–64, 100–144, 149–165; Europe commonly 36–64 and 100–140 (144 varies by country); Japan 36–64 and 100–128 only — no 149–165. Power limits differ by country and sub-band; confirm before deployment.
| Item | Value |
|---|---|
| Frequency range | 5925–7125 MHz (1200 MHz) |
| Centre frequency | 5950 + 5 × channel (MHz) |
| FCC sub-bands | U-NII-5 5925–6425 · U-NII-6 6425–6525 · U-NII-7 6525–6875 · U-NII-8 6875–7125 |
| US power modes | LPI (indoor) ≤30 dBm EIRP · VLP ≤14 dBm EIRP (outdoor allowed) · Standard Power ≤36 dBm EIRP with AFC |
| Security | WPA3 mandatory |
| Channel counts (full band) | 20 MHz × 59 · 40 MHz × 29 · 80 MHz × 14 · 160 MHz × 7 · 320 MHz × 3 |
Availability: the US (FCC 20-51, 2020), Canada, South Korea and others opened the full 1200 MHz; Europe and the UK have so far opened the lower 500 MHz (5925–6425 MHz), with the upper part tied to future WRC decisions. Confirm the current position per market.
| Feature | What it changes |
|---|---|
| 320 MHz channels | Double the widest Wi-Fi 6 channel; only practical in 6 GHz |
| MLO (Multi-Link Operation) | A device uses two or more links across bands/channels at once — lower latency, better resilience |
| 4096-QAM | Higher peak rate at close range and high SNR |
| Up to 16 spatial streams | More MIMO capability for APs |
| Backward compatibility | Works with 802.11a/b/g/n/ac/ax clients |
Antenna implication: Wi-Fi 7 does not change the fundamental bands, but MLO means a client may use 2.4, 5 and 6 GHz simultaneously. An antenna marketed as "2.4/5 GHz" will not serve the 6 GHz link. For Wi-Fi 6E/7 products, specify an antenna covering 2400–7125 MHz, or separate elements per band.
| Product | Bands the antenna must cover | Typical antenna |
|---|---|---|
| Wi-Fi 4/5/6 client (2.4 + 5 GHz) | 2400–2500 and 5150–5850 MHz | Dual-band PCB/FPC or external dipole |
| Wi-Fi 6E / 7 client | 2400–2500, 5150–5850, 5925–7125 MHz | Tri-band internal antenna or multiple elements |
| BLE / Zigbee / Thread only | 2400–2483.5 MHz | Single-band 2.4 GHz chip or PCB antenna |
| Dual-band AP with DFS | Full 5 GHz including DFS sub-bands | Antenna must hold VSWR across 5150–5850 MHz |
A "2.4/5.8 GHz" antenna covers the classic ISM Wi-Fi bands but not the 5 GHz U-NII-1/2/3 range between 5150 and 5725 MHz. Check the printed range against the channels you will actually use — 5.8 GHz (U-NII-3, 5725–5850 MHz) is only the top slice of 5 GHz Wi-Fi.

Channel availability, power limits and 6 GHz opening status vary by country and change over time. Confirm with your local regulator before deploying in a new market.
