Regulatory Certification
In an effort to improve radio spectrum management and promote a more efficient use of it, the regulatory bodies are trying to adopt a new spectrum access model. This represents a paradigm shift from hardware-embedded policy implementation to dynamic software-based adaptation. The biggest challenge is how to provide the same level of protection to incumbent services while allowing new radio technologies such as cognitive radio to have wider range of spectrum access (DSA).
Regulatory Challenges
The spectrum is already allocated
True spectrum scarcity on urban areas (ISM band)
We need to deal with existing standards
The standards are embedded in the hardware!
Proceedings that are the Key Drivers
Receiver Standards: ET Docket No. 03-65 NOI
Interference Temperature: ET Docket 03-237 NPRM/NOI
Cognitive Radio: ET Docket No. 03-108 NPRM
License-exempt Operation in the TV Broadcast Bands: ET Docket No. 04-186
Additional Spectrum for License-exempt devices below 900 MHz and in the 3 GHz Band: ET Docket No. 02-380
Interference Temperature Model
IT is "a measure of the RF power generated by undesired emitters plus noise sources that are present in a receiver system (I + N) per unit of bandwidth," or, in other words, the temperature equivalent of such RF power measured in units of ?Kelvin? (K). IT= (I+N)/kB. ET Docket No. 03-237, Nov. 2003
Our CE research will include the development and implementation of a Policy Engine (PE). We plan to leverage on existing work conducted by DARPA XG program. With regards to FCC certification, it has always been an important issue. We have monitored the Commission's stance with respect to the technology under deveopment. Our approach intends to assure complete compliance. Moreover, thee FCC has read and informally endorsed the procedure described in our proposal.
