3. Test and Measurement Task Group (T&M-TG)
November 2009
Test and Measurement Task Group (T&M-TG)
The task group’s goal is to define general requirements and test methodologies for SDR and cognitive radio, specifically for the TV white spaces band
Group is chaired by Bob Cutler from Agilent 
Project name is “Test Guidelines and Requirements for Television Band Devices (TVBDs) Designed to Operate on Available Channels in the Broadcast Television Frequency Bands”
Results are a report called
Test and Measurement of functions for Software-Defined/Cognitive Radios: Part 1 Test Guidelines and Requirements for Television Band Devices (TVBDs) Designed to Operate on Available Channels in the Broadcast Television Frequency Bands

4. Report Timeline Call for participation (November, 2009)
Report outline (mid February, 2010)
Requirements and considerations survey
Use cases
List of specific test needs
Workshop early next year (March 8-11, 2010)
Briefing to FCC and OFCOM staffs
Complete test methodologies for each identified test (July, 2010)
Test equipment functionality and performance (August, 2010)

“Test and Measurement of functions for Software-Defined/Cognitive Radios: Part 1”
Report will identify unique test challenges created by SDR/CR radio system technology used for TVBDs and will provide a basis for test and certification
Being developed for
Equipment manufacturers
Certification authorities
Test & measurement vendors
Test & evaluation departments
End-users dealing with radio systems supporting SDR/CR features
Wireless service providers
Each of these have to deal with SDR/CR technology-driven features such as dynamic waveform activation, opportunistic scheduling, policy based operation, spectrum sensing and interference avoidance
Features that are not seen in traditional dedicated functionality radio systems.

6. Challenges Detector testing Sensitivity (-114, below noise floor)
November 2009
Challenges
Detector testing
Sensitivity (-114, below noise floor)
Adjacent channels leaking into the channel of interest and causing a false detect
What’s defined as a failure (false detection currently is… is this right?)?
Dynamic cognitive radio functions (jumping to a channel away from interference)
TV bands database requirements testing
