WiFi Coverage Area Calculator

Calculate WiFi access point coverage area based on signal parameters and environment

The output power of the access point radio, typically 15-23 dBm for enterprise APs. Higher power extends range but may cause interference.
dBm
Antenna gain in dBi. Omnidirectional indoor antennas are typically 2-5 dBi. Directional antennas can be 6-15 dBi.
dBi
Minimum signal level the client can decode. Typical values: -65 dBm for high throughput, -75 dBm for reliable connectivity, -85 dBm for basic connectivity.
dBm
Higher frequencies have greater free-space path loss. 5 GHz has roughly half the range of 2.4 GHz in open space.
Different environments add attenuation. Open space has no extra loss, offices have cubicles/walls, dense walls add significant loss per wall.
