[* 1]. The radio wave intensity at a particular point is called "electric field intensity" in wireless terms, but it is generally set as "electric wave intensity" which is easy to understand. With regard to this intensity, what the application software can measure is mostly "received power", but the benchmark is the communication speed and the ratio of signal to noise (the ratio of signal to noise).

[* 2]. Due to Google's specification change, scanning cannot be performed without giving the application access to location information. If the chart is not displayed, try switching from settings to "Wifi Analyzer" in [apply] "[permissions]" [location Information]

Click Wi-Fi scan in the AirMac utility to display the surrounding SSID. If it is not scanned, click "scan" in the upper right corner, then click the SSID of the home Wi-Fi, and then display the list over time. The item "RSSI" indicates the intensity of the airwaves.
