Wireless channelization

摘要

A wireless device may be configured to operate in one of two modes where each mode uses a different channel list to perform operations in accordance with the IEEE 802.11 standard. In a first mode, the wireless device operates as an access point that sets up channels using one channel list in order to facilitate communications within a basic service set (BSS). In a second mode, the wireless device uses a second channel list to operate as a station and scan for a BSS. The first channel list contains a subset of the channels contained in the second channel list. The channels in each respective channel list may be reconfigured to adapt to changes in the configuration of a BSS and the devices communicating therein.

主权项

1. A method for communicating data within a wireless network, the method comprising:
configuring a first wireless device to operate in a first mode and a second mode, the first mode operating in accordance with a radio protocol and the second mode operating in accordance with the radio protocol; generating a first channel list including a plurality of channels supported in a first version of the radio protocol; generating a second channel list including a plurality of channels supported in one or more legacy versions of the first version of the radio protocol, the second channel list including at least a subset of the channels in the first channel list; scanning for communications from other wireless devices on channels from the first channel list when the first wireless device operates in the second mode; and setting up communications within the wireless network using channels only from the second channel list when the first wireless device operates in the first mode.
