Abstract

Abstract One embodiment of the invention includes assigning channels to a set of access points coupled to a network. The network includes a set of wireless network nodes. Each access point communicates, using one of the channels, to a subset of the wireless network nodes. Each channel corresponds to a different frequency range in the electromagnetic spectrum. The embodiment includes the following steps. At least a first access point of the set of access points transmits a plurality of messages. A measure of interference between access points communicating on a first channel is determined from the plurality of messages. A second set of channel assignments, that results in a lower amount of interference between access points communicating on the first channel, is determined. The second set of channel assignments is assigned to the set of access points. Thus, non-interfering frequency assignments for the access points can be determined.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 152 words
A network manager for reducing the amount of interference between access points communicating on a network, said network manager comprising: a processor, coupled to communicate with a plurality of access points, for transmitting at least a first request message, said first request message for causing at least a first access point to determine a radio proximity of one or more neighbor access points of said first access point, said processor further for determining a set of channel assignments for said plurality of access points from at least said radio proximity, said set of channel assignments reducing an amount of interference in said radio proximity caused by a subset of said one or more neighbor access points communicating using a portion of the electromagnetic spectrum used by said first access point; and a memory, being coupled to said processor, for storing instructions and a value corresponding to said radio proximity for said processor.
Claim 2
Dependent Claim 152 words
A network manager for reducing the amount of interference between access points communicating on a network, said network manager comprising: a processor, coupled to communicate with a plurality of access points, for transmitting at least a first request message, said first request message for causing at least a first access point to determine a radio proximity of one or more neighbor access points of said first access point, said processor further for determining a set of channel assignments for said plurality of access points from at least said radio proximity, said set of channel assignments reducing an amount of interference in said radio proximity caused by a subset of said one or more neighbor access points communicating using a portion of the electromagnetic spectrum used by said first access point; and a memory, being coupled to said processor, for storing instructions and a value corresponding to said radio proximity for said processor.
Claim 3
Dependent Claim 48 words
The network manager of claim 1 wherein said processor is further for transmitting at least a second message, said second message being generated from said set of channel assignments, said second message for causing at least one access point of said plurality of access points to change channels.
Claim 4
Dependent Claim 34 words
The network manager of claim 1 further comprising a display device, being coupled to said processor, and wherein said processor is further for causing a display of a graphical representation of said radio proximity.
Claim 5
Dependent Claim 36 words
The network manager of claim 1 wherein said processor is further for processing at least a first message received from said first access point, said first message indicating said radio proximity for said first access point.
