How does the Online Power Profiler for Wi-Fi tool calculate energy consumption

How does the Online Power Profiler for Wi-Fi tool calculate energy consumption, and is there a formula or document explaining its energy consumption calculation principle?

For example, the transmission time of each WiFi packet and the power consumption of each transmission. as some blogs show in theory:

Hi,

The online power profiler does not use a generic formula but a model based on the protocol (Bluetooth LE, Wi-Fi, etc.) and current measurements for TX/RX, CPU, etc.

When it comes to Wi-Fi, the online power profiler only shows when the device is idle, that is, DTIM or TWT. Data transmissions are not included in this.

Best regards,
