First Trials of Collaborative Dynamic Spectrum Access, Cognitive Radio Succeed | Wireless IQ

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.

Google filed a proposal on Monday with the Federal Communications Commission calling on the agency to let companies allocate radio spectrum using the same kind of real-time auction that the search engine company now uses to sell advertisements.

Software defined radio gets configurable RF - 16/05/2007 - Electronics Weekly

TechnoConcepts of Boston, which is developing a re-configurable RF front end for software defined radio (SDR) systems, has a design in which its RF front end is plugged into a re-configurable baseband from PicoChip of Bristol.

The combination allows the possibility of a fully reconfigurable SDR system in which the same piece of silicon can act successively as different radio standards, said the company.

This first platform is confined to WiMAX. Since WiMAX is notorious because the spectrum frequencies allocated to it vary from country to country, 2.1GHz in the US, 2.3GHz in Korea, 2.5GHz in Europe and 3.4GHz, 3.6GHz, and 4.9GHz elsewhere, a reconfigurable platform is a suitable starter product for a re-configurable wireless platform.

“This is very much a Phase One product,” Rupert Baines, v-p for marketing at PicoChip, told EW, “it’s just for WiMAX because it has so many different systems, so many different frequencies.”

ComReg welcomes moves to trial DSA technology: CommsUpdate : TeleGeography Research

The Irish telecoms regulator, the Commission for Communications Regulation (ComReg), has invited companies to begin trialling so-called ‘intelligent radio’ or Dynamic Spectrum Access (DSA) technology, which it believes offers additional benefits to advanced technologies such as Wi-Fi. According to online news portal siliconrepublic.com, ComReg said on Friday that DSA technology is about ‘maximising the use of the radio spectrum by gaining access to highly sought after frequencies at certain times or in certain locations’. It could offer benefits to mobile and broadband by accessing greater parts of the radio spectrum and accessing it faster. Ofcom in the UK is also exploring the possibilities of using DSA and is currently looking at advanced roaming applications for mobile phones, PDAs and other mobile devices. ComReg chairman Mike Byrne said: ‘ComReg is keen to encourage innovative developments and more efficient ways to use spectrum. We wish to encourage development in these technologies through our test-and-trial licence scheme… We would like to invite interested parties to consider using the test-and-trial licence scheme to investigate the potential of this technology.’
