The world’s first collaborative dynamic spectrum access and cognitive radio trials were performed by the second IEEE International symposium on New Frontiers in Dynamic Spectrum Access Networks (DySPAN). Held in Dublin, Ireland, DySPAN gathered 300 of the world’s foremost wireless experts, many of whom participated in the trials conducted at the Centre for Telecommunications Value-Chain Research (CTVR), headquartered at University of Dublin, Trinity College.
The Irish Commission for Communications Regulation (ComReg) awarded CTVR a trial license enabling several leading global companies and research groups, which includes Motorola, Shared Spectrum Company, Virginia Tech University, QinetiQ, University of Kansas, and SRI International, to participate in the trials. Licensed and license-exempt frequency spectrum segments in the VHF/UHF and microwave bands were used by the companies during the trials.
