System and method for dynamic channel selection in IEEE 802.11 WLANs
First Claim
1. A method comprising:
- receiving a link quality value of a current channel from each of a plurality of wireless stations in a wireless network;
using the received link quality values to determine whether link quality of the current channel fails a link quality threshold; and
if the link quality fails the link quality threshold, thenreceiving a signal value of each of at least two other channels from each of the plurality of wireless stations;
using the received signal values to determine whether each of the at least two other channels is a candidate channel;
using a channel-selection protocol that includes random selection to select one of the candidate channels as a new channel; and
setting the new channel as the current channel.

Abstract
A method comprising receiving a link quality value of a current channel from each of a plurality of wireless stations in a wireless network; using the received link quality values to determine whether link quality of the current channel fails a link quality threshold; and if the link quality fails the link quality threshold, then receiving a signal value of each of at least two other channels from each of the plurality of wireless stations; using the received signal values to determine whether each of the at least two other channels is a candidate channel; using a channel-selection protocol that includes random selection to select one of the candidate channels as a new channel; and setting the new channel as the current channel.

10. A system comprising:
-
a current channel assessment module for receiving a link quality value of a current channel from each of a plurality of wireless stations in a wireless network, and for using the received link quality values to determine whether link quality of the current channel fails a link quality threshold; a candidate channel assessment module for receiving a signal value of each of at least two other channels from each of the plurality of wireless stations, and for using the received signal values to determine whether each of the at least two other channels is a candidate channel; a new channel selection module for using a channel-selection protocol that includes random selection to select one of the candidate channels as a new channel; and a new channel setting module for setting the new channel as the current channel. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A wireless station in a wireless network, comprising:
-
means for determining a link quality value of a current channel; means for determining a signal value of each of at least two other channels; and means for determining a new channel designation, the new channel designation being generated by a channel-selection protocol that includes random selection, and for setting the new channel as the current channel. - View Dependent Claims (20)
