November 2009 doc.: IEEE 802.11-09/1123r0 November 2009 Abstract This contribution discusses the on-going work being performed at the SDR Forum’s Test and Measurement Task Group (T&M-TG) John Ziegler, octoScope, Inc John Ziegler, octoScope, Inc

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 John Ziegler, octoScope, Inc

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) First draft report (September, 2010) Final report (October, 2010) John Ziegler, octoScope, Inc

November 2009 “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.

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 John Ziegler, octoScope, Inc
