Abstract
A method of selecting between telecommunication networks for at least two terminals capable of exchanging data in a first frequency band of a first telecommunication network with subscription and in a second frequency band of a second telecommunication network without subscription includes the steps of: estimating the relative distance between the two terminals; and switching the operation frequency of each of these two terminals from the first frequency band to the second frequency band if the distance between the two terminals is smaller than a predetermined value.
