Wireless spectrum is becoming a vital and scarce resource due to the increase development and deployment of mobile device and their associated applications. Dynamic Spectrum Access (DSA) represents one of the few ways that our nation can be able cope with our anticipated spectrum crisis1. Wireless communications is a key tool in today’s economy and efficient use of this spectrum is paramount. I commend the National Telecommunications and Information Administration (NTIA) and associated vendors for assuming the arduous task in testing these new devices and techniques, which are critical for the advancement of policy and technology of future DSA systems. Additionally, I am appreciative of the opportunity to provide feedback to the NTIA for phase II/III test plans. The overall purpose of this feedback is to provide insight to insure that these tests proceed efficiently and effectively as possible.
