Abstract

Channel bonding techniques for wireless networks are described. In one embodiment, for example, an apparatus may comprise a memory and logic for a wireless communication device, at least a portion of the logic implemented in circuitry coupled to the memory, the logic to generate a channel bonding request frame for transmission to a remote device, the channel bonding request frame to comprise first channel information indicating a plurality of locally-clear wireless channels, the logic to identify, based on second channel information comprised in a received channel bonding response frame, a bonded channel set comprising two or more of the plurality of locally-clear wireless channels, and generate a data frame for transmission to the remote device via a combined bandwidth of the bonded channel set. Other embodiments are described and claimed.
