Cognitive Radio Network Testbed (CORNET)

The Virginia Tech CORNET is a collection of high performance servers, unique and extremely flexible RF hardware, and software-defined radio architectures. The CORNET graduate students and staff have integrated these pieces into a resource for next-generation wireless system developers around the world to rapidly prototype, extensively test, and compare Cognitive Radio techniques, Software-Defined Radio components, and Dynamic Spectrum Access technologies on a larger scale that is outside of the traditional simulation environment.

Primary Testbed Characteristics

CORNET has many attributes that make it a unique resource for wireless system developers.
