Abstract
A method for estimating the speed of a user equipment connected to a base station of a wireless network, the method comprising the following steps: measuring the power of a signal transmitted between the user equipment and the base station; computing the derivative of the measured signal power with respect to time; computing the standard deviation of the computed derivative; estimating, from previously established reference data, the speed of the user equipment that corresponds to the computed standard deviation, the reference data associating a given user equipment speed with a certain computed standard deviation.
