摘要: The invention relates to a cognitive radio (CR) WiFi network which includes a plurality of radio environment aware WiFi terminals, which collect local WiFi interference information and send this information to a CR network management system (NMS). The CR NMS includes a database for storing historical records of the interference information obtained from the terminals, and cognitive engines for analyzing the stored historical interference records and determining terminal-specific transmission and reception parameters. In one embodiment the network implements a deterministic NMS-directed networks-wide TDD/TDM scheduling of WiFi communications for optimal channel re-use and interference avoidance, and a novel terminal synchronization mechanism.
