<p>The invention relates to a device and a procedure at a cellular radio communication system for simulation of that a mobile telephone is at a big distance from a base station. This simulation can be effected by that one delays a transmitted RF-signal between the mobile telephone and the base station. The delay is effected in such a way that the RF-signal is mixed down to an MF-signal, at which the MF-signal is delayed by means of a delay device. After the delay of the MF-signal, one again mixes it up to an RF-signal.</p> |
