Wi-Fi Channel Explorer

Convert between Wi-Fi channel numbers and center frequencies, and explore channel geometry across the 2.4, 5, and 6 GHz bands. The explorer shows technical channel relationships only; permitted use depends on the country, device class, and operating conditions.

Channel number

Enter a center frequency or channel number.

Quick help

Select a frequency range and, if needed, a bandwidth to narrow the table and visualization. Enter an exact center frequency, channel number, or channel notation. With “All ranges” or “All bandwidths,” values that identify more than one channel geometry are shown as separate matches.

Wi-Fi bands and channel geometry

The explorer shows standardized channel center frequencies and bonded-channel geometry. A bonded channel comprises multiple 20 MHz channels; the primary channel depends on the device configuration and is not prescribed by the explorer.

Regulatory and technical context

Channel availability cannot be determined from geometry alone. Permitted use depends on the country or region, device class, indoor or outdoor operation, power category, and applicable mechanisms such as DFS, TPC, or AFC.

Terms and mechanisms: DFS · TPC · AFC · U-NII Bands

Regional standards: FCC §15.407 · ISED RSS-247 · ARIB STD-T66 · ARIB STD-T71
