COMMUNICATION METHOD FOR USE IN A WIRELESS TERMINAL IN A OFDM COMMUNICATION SYSTEM, AND WIRELESS TERMINAL FOR USE IN A COMMUNICATION SYSTEM Methods of carrier frequency selection and connection initiation in multi-frequency wireless systems are described. of carriers. Although the receiver is tuned to a single band, based on the relative energy of one or more beacon signal components corresponding to the currently used carrier and one or more beacon signal components corresponding to an alternative carrier, a selection of carrier and a connection is determined. Mobile nodes can use a single RF string with a controllable RF filter to receive and process a first band of selected carriers that include components from different transmitters, for example, a first identified signal component with a currently selected first band and a second. signal component identified with a second alternative band. Signal components, for example beacon signal components from different transmitters, may be obtained from a signal corresponding to multiple symbol transmission time periods. Separate measurements of signal energy are performed on the first and second signal components. The power of the signal component is compared and a determination is made as to whether to initiate a connection.
