Abstract:
1. A computer program product for use by a wireless device in a wireless communications environment, the program product comprising a computer readable medium having embodied therein a computer program for storing data, the computer program comprising: logic for associating the wireless device with a current access point on a first channel; logic for ascertaining, by the wireless device, whether the wireless device should attempt to associate with an alternative access point operating on a second channel, the ascertaining logic utilizing, at least in-part, signal strengths of transmissions from the alternative access point, and technology type employed by the alternative access point; logic for requesting association with the alternative access point if it is ascertained that the wireless device should attempt to associate with said alternative access point; and logic for automatically collecting, by the wireless device, information about access points operating on other channels, including indications of transmit power backoff; wherein the logic for ascertaining obtains an indication of expected data rate of service by the alternative access point, and ascertains that the wireless device should attempt to associate with the alternative access point operating on said second channel if the alternative access point on said second channel has a greater expected data rate than an actual data rate provided by the current access point.
