Abstract
To carry out tests on a mobile telephony network, a two-band mobile telephone is used. This mobile telephone is improved by a parametrizing device by which the mobile telephone declares itself to the network either as a single-band telephone in a first frequency band, or as a single-band telephone is a second frequency band, or as a two-band telephone in both these frequency bands. The network then exploits the mobile telephone in the mode corresponding to its declaration. It is possible with only one instrument, to measure all the transmission characteristics of the network.
