Abstract :
The FCC issued its first Report and Order in September 2001 on Software-Defined Radio. It commissioned a follow-on inquiry on SDR security issues and another on the potential for unlicensed usage of TV spectrum, facilitated by software radio technology. Spectrum managers in Europe, USA and Asia held a regulators forum in the UK in September 2003, which reviewed SDR approaches and the potential regulatory actions required of national spectrum managers.
