Abstract

An access point in a wireless network includes an external indication of the access point's proximity to another access point. The external indication can be a LED that blinks at a rate that is related to the proximity of the access point to the other access point. An access point is also capable of producing a network map that indicates the access point's proximity relative to other access points that are coupled to the network. The access point is further capable of monitoring wireless network traffic to ascertain whether wireless network traffic has exceeded a threshold, and if so, releasing some client devices so that wireless network traffic no longer exceeds the threshold. The access point is also capable of automatically choosing one of a plurality of radio frequencies on which to operate. The access point chooses a frequency after evaluating frequencies on which other access points may be operating.

Dependent claims

An access point operable to provide wireless network access to client devices coupled to a wireless network, the access point comprising:

a controller that automatically chooses one of a plurality of radio frequencies on which to operate, said controller choosing said frequency after evaluating frequencies on which other access points operate, said controller comprising:
a. logic for picking a frequency;
b. logic for transmitting on said frequency;
c. logic for receiving on said frequency;
d. logic for evaluating whether other access points are heard on said frequency;
e. logic for reducing transmission power;
f. logic for evaluating whether said other access points are still heard on said frequency;
g. logic for storing the transmission power at which no other access points are heard;
h. logic for picking a next frequency as the frequency and repeating steps b-g until all of the plurality of frequencies has been picked;
i. logic for comparing said stored transmission powers;
j. logic for choosing for operation the frequency associated with the highest stored transmission power.
