OVERLAPPING CHANNEL SCANS

摘要

While scanning through various channels to find network controllers that are both within range and available, the scanning device may cover multiple channels simultaneously by using a bandwidth that encompasses multiple channels. This may be particularly useful with WiFi devices that are using the 2.4 GHz band, in which the channel spacing may be about 5 MHz, while the channel bandwidth may be about 22 MHz.

主权项

1. A method of wireless communication, comprising:
transmitting a first probe request on a first channel; receiving a first response, the first response identifying a first device transmitting the first response and identifying a second channel on which the first response was transmitted; wherein the first channel is different than the second channel, the first channel has a bandwidth encompassing at least a part of the second channel, and the second channel has a) o bandwidth encompassing at least a part of the first channel.
