Access Point Cell Designing Method by Considering Radio Interference in Channels of Wireless Local Area Network

摘要

PURPOSE: A method for designing an AP(Access Point) cell with respect to RF(Radio Frequency) interference between wireless LAN(Local Area Network) channels is provided to reduce the RF interference generated between adjacent AP channels by effectively selecting positions of APs and a channel when installing a plurality of APs for a wireless LAN. CONSTITUTION: Positions of a plurality of APs are designed so that a service null area is completely solved. The first to fourth channels, in which the narrowest bandwidths are overlapped each other, are selected among channels used in a wireless LAN. The first to fourth channels are assigned to peripheral APs in the first direction centering around contact points in which angles are 0 degree and 180 degrees among four contact points in which a plurality of AP coverage circles are overlapped. The first to fourth channels are assigned to peripheral APs in the second direction centering around contact points in which angles are 90 degrees and 270 degrees among the four contact points. A channel which is the most distant from an adjacent AP is assigned to an AP to which the channel is not assigned so that the channel of the adjacent AP is not overlapped.
