In a wireless communication system, ranging is performed between an initiator and one of a plurality of responders. Before the ranging operation is performed, the initiator preselects the responder, wherein the preselection is based on a comparison of a measured metric associated with signals carrying packets received from the responders by the initiator. The initiator utilizes only a portion of the preamble in each of the packets to measure the metric. The signals are transmitted in the wireless communication system utilizing ultra-wideband frequencies.
