This tool is based on a model of measured values and is not showing the actual power measurements. The results are therefore an estimate of the expected current consumption values.
The measurements which the model is based upon are conducted on a nRF7002 DK board while communicating with a Wi-Fi 6 AP. This is a controlled test environment representing in many cases ideal conditions which may not be reproducible in a real network environment. It does not consider poor signal conditions or channel contention, which would result in packet errors and retransmissions.
