UNII-bånd
UNII (Unlicensed National Information Infrastructure) er frekvensbånd, som er anvendt af fx Wi-Fi5, Wi-Fi 6 og Wi-Fi 6E rlan-udstyr og af mange trådløse internetudbydere.
UNII er en USA FCC regulatorisk domæne for 5-7 GHz trådløst udstyr. Den europæiske HiperLAN standard opererer i UNII-båndet.
UNII-bånd udgøres af flere dele:
| Må anvendes i EU (EU del af EMEA) | Navn | Alias | Frekvensinterval (GHz) | Båndbredde (MHz) | Max effekt (mW) | Max EIRP (mW) |
|---|---|---|---|---|---|---|
| ja[1][2][3] | U-NII-1 | U-NII Low / U-NII Indoor | 5,150–5,250 | 100 | 50 | 200 |
| ja[1][2][3] | U-NII-2A | U-NII Mid | 5,250–5,350 | 100 | 250 | 1.000 |
| nej | U-NII-2B | 5,350–5,470 | 120 | — | — | |
| ja[1][2][3] | U-NII-2C | U-NII Worldwide / U-NII-2-Extended / U-NII-2e | 5,470–5,725 | 255 | 250 | 1.000 |
| nej | U-NII-3 | U-NII Upper | 5,725-5,850 | 125 | 1.000 | — |
| nej | U-NII-4 | DSRC/ITS | 5,850–5,925 | 75 | — | — |
| ja (kun 5,945-6,425)[4] | U-NII-5 | 5,925–6,425 | 500 | — | — | |
| nej | U-NII-6 | 6,425–6,525 | 100 | — | — | |
| nej | U-NII-7 | 6,525–6,875 | 350 | — | — | |
| nej | U-NII-8 | 6,875–7,125 | 250 | — | — |
Wireless ISP anvender typisk 5,725-5,825 GHz.
