A wireless telecommunication device, a method of frequency calibrating a
wireless telecommunication device, and a computer program are provided.
The method comprises: receiving a reference radio signal of the wireless
telecommunications system; frequency synchronizing the wireless
telecommunication device with the reference radio signal by adjusting a
control parameter controlling a reference frequency generated by a
reference frequency generator; measuring a temperature parameter
characterizing the temperature of the reference frequency generator; and
generating calibration information for calibrating the wireless
telecommunication device on the basis of the control parameter and the
temperature parameter.
