This pilot program is an opportunity for the Federal agencies to workcooperatively with industry, researchers, and academia to examine objectively newtechnologies that can improvemanagement of the nation’s airwaves. The Test-Bed pilot program is evaluating the ability of Dynamic Spectrum Access(DSA) devices employing spectrum sensing and/or geo-location techniques to sharespectrum with land mobile radio (LMR) systems operating in the 410-420 MHz Federalband and in the 470-512 MHz non-Federal band.1To address potential interferencetoincumbent LMR spectrum users, the Test-Bed pilot program includes both laboratory andfield measurements performed in three phases to characterize the interaction with DSAenabled devices: Phase I–Equipment Characterization. Participants in the Test-Bed sendequipment employing DSA techniques to the NTIA Institute forTelecommunication Sciences (ITS) in Boulder, Colorado to undergocharacterization measurements of the DSA capabilities in response to simulatedenvironmental signals. Phase II–Evaluation of Capabilities. After successful completion of Phase I,NTIA will examine the DSA spectrum sensing and/or geo-location capabilities ofthe equipment. Phase III–Field Operation Evaluation.After successful completion of PhaseII, NTIA will test the DSA equipment in an actual radio frequency signalenvironment using an automatic signal logging capability to help resolveinterference events if they occur. NTIA will establish a point-of-contact to stopTest-Bed operations if interference is reported. NTIA selected the following parties to participate in the Test-Bed pilot program:Adapt4 LLC, Adaptrum Inc., BAE Systems, Motorola Inc., Shared Spectrum Company,and Virginia Polytechnic Institute and State University. During fiscal years 2008 and 2009, NTIA completed the development of the Test-Bed pilot program Phase I test plan, the coordination of the test plan with the Federalagencies and Test-Bed participants, the publications and public comments of the test plan, and began the laboratory testing of the first and second DSA devices. All of thedocuments related to the Test-Bed pilot program are available athttp://www.ntia.doc.gov/frnotices/2006/spectrumshare. This progress report describes the activities related to the Test-Bed pilot programthat NTIA undertook during Fiscal Year 2010. II.OVERVIEW OF DYNAMIC SPECTRUM ACCESS TECHNOLOGIES NTIA staff members met with each of the Test-Bed participants to discuss theirDSA devices. Table 1 provides a high level overview, based on information provided bythe Test-Bed participants, of the different DSA devices being tested by NTIA. III.PHASE I TEST PLAN NTIA completed the coordination of the Phase I test plan with the Federalagencies and Test-Bed participants in November 2008 and published the coordinatedPhase I test plan in theFederal Registerfor public review and comment in December2008.2NTIA addressed the public comments on the test plan and published a finalversion on the NTIA website in February 2009.3 The Phase I test plan breaks the test cases down into five categories for eachDevice Under Test (DUT): emission characterization, sensor characterization, spectrumaccess behavior, LMR emission characterization, and LMR receiver performancecharacterization. Figure 1 shows an overview of the proposed test cases to be performedunder Phase I. All Phase I testing will be performed at the ITS laboratory. IV.FISCAL YEAR 2010 ACTIVITIES Phase I Testing NTIA completed the Phase I laboratory testing of the DSA devices from Test-BedParticipant A. NTIA is currently preparing a test report for the Test-Bed Participant Adevices based on the Phase I measurement data. The ITS laboratory received DSA devices from Test-Bed Participant B in August2009. NTIA initiated the Phase I laboratory testing of the Test-Bed Participant B DSAdevices in November 2009. NTIA has completed approximately 60 percent of the PhaseI laboratory testing. The ITS laboratory received DSA devices from Test-Bed Participant F in October2010. The Test-Bed Participant F staff provided training on the use of their devices andpertinent documentation. NTIA has completed approximately 10 percent of the Phase Ilaboratory testing of these DSA devices. ITS e
