Before revision: Estimated received signal strength The estimated received signal strength in an active RFID tag can be estimated as follows: In general, you can take the path loss exponent into account: ParameterDescriptiondBmeEstimated received power in active RFID tag −43Minimum received power 40Average path loss per decade for mobile networksDistance mobile device - cell towerMean radius of the cell towerPath loss exponent The effective path loss depends on frequency, topography, and environmental conditions.
