Wi-Fi Throughput Estimator
Use this wi-fi throughput estimator entirely in your browser.
Equal-share estimate: 110 Mbps per active device.
Real throughput varies with signal, interference, protocol overhead, and device capability.
Calculations happen locally in your browser.
Why Wi-Fi PHY speed is not file-transfer speed
Advertised PHY rate is a signalling rate. Airtime contention, half-duplex operation, channel width, signal quality, retransmissions, protocol overhead, access-point capability, and client radios all affect usable throughput. Treat the result as a planning estimate, not a guarantee.

如何 calculation works
Advertised PHY rate is multiplied by a user-selected efficiency estimate, then divided across active devices.
