Abstract: The patent describes a wireless networking system that includes an application layer with one or more applications having wireless bandwidth requirements. It utilizes first and second wireless transceiver resources, each associated with an actual Media Access Control (MAC) layer and Physical (PHY) layer, and having respective bandwidth availabilities. A processing layer evaluates these bandwidth requirements and availabilities. This processing layer includes a bandwidth allocator that assigns portions of the actual bandwidths to virtual MAC and virtual PHY layers to meet the application layer's wireless bandwidth requirement.

Plain-Language Overview of Independent Claims:

Independent Claim 1: This claim outlines a method to enhance the performance of a wireless networking device. It involves connecting an application interface (for a primary application with a data stream and bandwidth need) and actual MAC and PHY interfaces of at least two different wireless transceivers to a central processing interface. These transceivers operate in different frequency bands and are suitable for Wireless Local Area Networks (WLANs). Within the processing interface, virtual MAC and PHY layers are created. During operation, these virtual layers provide feedback about the transceivers' available bandwidth to the virtual MAC layer. The processing interface, acting transparently to layers above it, then associates a recipient with both actual MAC and PHY interfaces. It identifies a portion of the first transceiver's bandwidth, evaluates if any of its resources are unavailable, and then uses the available resources within that bandwidth portion to transmit the data stream to the recipient. Crucially, this transmission does not require the recipient to disconnect from either of the actual MAC and PHY interfaces, and the use of this bandwidth portion by the networking device does not prevent other devices from using the remaining frequencies of that transceiver simultaneously.
