Prior art

The current date is 2026-05-19.

US Patent 12114177 describes a method and apparatus for processing bandwidth-intensive data streams using virtual Media Access Control (MAC) and Physical (PHY) layers. Key features include the evaluation of application bandwidth requirements, the dynamic allocation of portions of bandwidth from multiple wireless transceiver resources (each with its own actual MAC and PHY layers and potentially different frequency bands) to virtual MAC and PHY layers, and the ability for these allocated portions to be used transparently to higher layers. The system also supports simultaneous utilization of remaining bandwidth by other devices and concepts like variable duplex links and network range extension via multiple access points.
