1. A method in a wireless terminal comprising:
- receiving information about at least one traffic channel regarding transmission power and at least one transmission frequency of a first transceiver,determining at least one harmonic of the at least one transmission frequency of the first transceiver for obtaining at least one barred frequency range, the barred frequency range comprising the determined at least one harmonic,measuring signal strength transmitted by the first transceiver,calculating a quality factor for the at least one traffic channel as a ratio of the measured signal strength and the information regarding the transmission power,selecting at least one channel for use in a second transceiver by taking into account the at least one barred frequency range and the quality factor, anddetermining for a transmission of a second transceiver a maximum data rate by using the information regarding the transmission power and the measured signal strength.

Abstract
Channel selection in a wireless telecommunication system includes determining at least one transmission frequency used by a first transceiver from information on the first transceiver. The harmonics of the transmission frequency are determined and at least one channel used by the second transceiver is selected by at least taking into account the harmonics of the transmission frequency of the first transceiver.
