<p>A method of measuring the quality of a mobile connection, in a mobile telephone system, has the following steps: establishing a mobile connection between a mobile handset and a fixed measurement station; transmitting predetermined test sequences from said mobile handset to said fixed measurement station and vice versa; storing sound signals received by said mobile handset and said fixed measurement station; and analysing said received sound signals to derive a measure of the quality of said mobile connection. A portable measurement briefcase, for use with the method, includes a mobile handset modified for the transmission of predetermined test sequences. A fixed measurement station, for use with the method, includes an ISDN-connected PC equipped with a DSP card.</p> |
