The transmit power of an AP affects the wireless coverage area
In WiFi Scanner you can see the RSSI or received signal strength indicator for any AP in your area under "Signal:"
The transmit power of an AP affects the wireless coverage area and the maximum achievable signal-to-noise ratio. Proper configuration of transmit power is important for ensuring a wireless network is operating at its highest capacity. An access point output power is measured in dBm.
The FCC regulates WiFi output power to a maximum of 1 watt (1000mW) in the U.S Access points, routers, and bridges. Standard office spaces: 10-14dBm @EIRP for 5GHz. 6-10dBm @EIRP for 2.4GHz. Also, Reducing transmit power reduces the range of the AP, such that a user associates only with the nearest AP in a room containing multiple APs. This helps distribute the users across the AP's deployed in a single physical space.
