MCS index and PHY rate lookup

This MCS index table looks up nominal MCS PHY rates from Wi-Fi 4 (802.11n) through Wi-Fi 7 (802.11be). Choose the Wi-Fi generation, channel width, spatial streams, MCS per stream and guard interval to see the nominal PHY rate in Mbps, the modulation, the coding rate and the reported MCS index, next to a table of every MCS for that setup. The rates are nominal PHY rates for one full channel, and actual throughput is lower.

FAQ

Using the Wi-Fi engineer toolbox

Are these Wi-Fi calculators free to use?

Yes. The tools run in your browser and do not require an account or subscription.

Do the tools replace a wireless survey or equipment datasheet?

No. They provide planning checks. Confirm assumptions with current vendor documentation, site conditions and survey measurements.

Where are my calculator inputs stored?
