Techniques for facilitating and reducing the costs associated with the installation of a wireless broadband communications system. In one mode of operation, the system employs a first transceiver to identify n channels having the n lowest levels of noise and interference associated therewith by a spectrum management technique. Next, the first transceiver transmits a predetermined code over the n channels to a second transceiver, which attempts to identify the predetermined code within a captured transmission. In the event the code is correctly identified, the second transceiver measures a noise and/or interference level associated with the corresponding channels. The channel having the lowest measured noise and interference level is then selected for use in system installation.
