Theoretical entropy assessment of fingerprint-based Wi-Fi localization accuracy

•The entropy is employed as a new metric to evaluate the fingerprint-based Wi-Fi location accuracy.•The relations of entropy and accuracy with variable RP densities and standard deviations are given.•The reckless increase of the number of APs cannot be an effective way to improve location accuracy.•...
