CHANNEL SELECTION METHOD IN A WIDEBAND HIGH FREQUENCY WIRELESS SYSTEM AND A DEVICE THEREOF, USING AN MAC(MEDIA ACCESS CONTROL) PROTOCOL OF A DISTRIBUTION METHOD

摘要

PURPOSE: A channel selection method in a wideband high frequency wireless system and a device thereof are provided to scan not only single channel but also bonded channels and to reduce setting time of not only a direct path between a source device and a destination device but also a detour path in a wideband high frequency wireless system using an MAC(Media Access Control) protocol of a distribution method.;CONSTITUTION: A channel scanning request frame generating unit(310) decides a channel to be scanned by a neighbor device among available channels and generates a channel scan request frame directing the channel to be scanned by a neighbor device. A transceiving unit(350) transmits the frame to the neighbor device and receives a response message from the neighbor device. A channel scanning unit(320) scans a channel except the channel to be scanned by a neighbor device. A channel selecting/switching unit(330) selects a channel for communicating with the neighbor device based on the response message and performs a channel switching to the selected channel.;COPYRIGHT KIPO 2010
