1. A method for spectrum-management of wireless access points, said method comprising:
- (a) using a network management system (NMS) to determine an overlapping area of wireless coverage of two or more access-points by receiving an indication of interference from one or more wireless stations communicating with at least one of the two or more access-points, wherein the indication comprises at least one retransmit request; and
(b) using a smart antenna to place a dynamic null in the direction of said overlapping area.

Abstract
Methods and corresponding systems for spectrum management featuring advanced frequency-allocation planning and advanced interference avoidance. The invention discloses access points that transmit directionally and assigning a predefined channel in a predefined direction, in order to reduce interference between closely located access-points.

18. A method of spectrum management in a wireless network, said method comprising:
-
mapping a set of multiple wireless stations communicating with a set of multiple wireless access points, which wireless access points have a set of wireless communication channels, including mapping levels of interference experienced by each of the multiple wireless stations and the directions of the interferences; and dynamically assigning channels of the multiple wireless access points, to the set of multiple wireless stations, according to a direct correlation of interference levels between the stations to the channels, including; assigning wireless stations experiencing a relatively high level of interference in relation to the set of multiple wireless stations to wireless channels experiencing a relatively high level of interference in relation to the set of wireless communication channels; and assigning wireless stations experiencing a relatively low level of interference in relation to the set of multiple wireless stations to wireless channels experiencing a relatively low level of interference in relation to the set of wireless communication channels. - View Dependent Claims (19, 20, 21)
