Abstract: A method of controlling a frequency selection of a PLL used in cooperation with a device of a wireless communication network, such as a Universal Mobile Telecommunication System (UMTS) network, the method comprising: —receiving a first set of signal measurements; —comparing the first set of signal measurements with a first threshold and, selectively switching the PLL frequency from a first value to a second value as a result of the comparison of the first set of signal measurements with the first threshold; —further receiving a second set of signal measurements; and, —comparing the second set of signal measurements with a second threshold, different from the first threshold, and selectively switching the PLL frequency from the second value to the first value as a result of the comparison of the second set of signal measurements with the second threshold.
