What metric implements the simplest algorithm and lowest accuracy in networks requiring locations?

Received Signal Strength Indicator (RSSI) is a metric that measures the power level of a received radio signal.In the context of location-based services within wireless networks, RSSI-based localization is known for its simplicity, as it doesn't require additional hardware or complex algorithms.However, this simplicity comes at the cost of accuracy.RSSI measurements can be significantly affected by environmental factors such as multipath propagation, obstacles, and signal interference, leading to less precise location estimations compared to other methods like AoA, ToA, or TDoA.Wray Castle
