Cognac: Cognitive Network Access
In this project, we are striving to re-imagine WiFi in a new world where spectrum may be fragmented (e.g, white spaces) and radios are feature-rich (e.g., cognitive, full-duplex, etc.). SpecNet is a platform for identifying spectrum utilization in real-time over a wide-area by leveraging measurements from multiple independent spectrum analyzers. WiFi-Nano and WiFi-NC enable WiFi to operate over fragmented spectrum in a much more efficient manner than WiFi.
