Spectrum Relocation Final Rule on Technical Panel and Dispute Resolution Boards
NTIA adopts regulations governing the Technical Panel and dispute resolution process established by Congress to facilitate the relocation of, and spectrum sharing with, U.S. Government stations in spectrum bands reallocated from Federal use to non-Federal use or to shared use. This action is necessary to ensure the timely relocation of Federal entities' spectrum-related operations and, where applicable, the timely implementation of arrangements for the sharing of radio frequencies.

Working Group 5 (WG5) Report from CSMAC Co-Liaisons
Fifteenth Quarterly Status Report to Congress Regarding BTOP
Pursuant to Section 6001(d)(4) of the American Recovery and Reinvestment Act of 2009 (ARRA or Recovery Act) (Public Law No. 111-5), the National Telecommunications and Information Administration (NTIA) provides this Quarterly Report on the status of the Broadband Technology Opportunities Program (BTOP or Program). This Report focuses on the Program’s activities from July 1 to September 30, 2012.
BTOP Fact Sheet
The American Recovery and Reinvestment Act of 2009 appropriated $4.7 billion for the National Telecommunications and Information Administration (NTIA) to establish the Broadband Technology Opportunities Program (BTOP). As required by the Act, NTIA designed this grant program to increase broadband access and adoption; provide broadband training and support to schools, libraries, healthcare providers, and other organizations; improve broadband access to public safety agencies; and stimulate demand for broadband.

Spectrum Resource Assessment in the 2.7 to 2.9 GHz Band Phase II: Measurements and Model Validation (Report No. 1)
The Office of Telecommunications (OT) undertook a detailed program to measure and analyze spectrum utilization in the 2.7. to 2.9 GHz band in the Los Angeles and San Francisco areas in support of an Office of Telecommunications Policy (OTP) Spectrum Resource Assessment task. The measurement program consisted of on-site visits to compare predicted and actual PPI interference patterns, and utilization of the Radio Spectrum Measurement System (RSMS) van to validate the component models used in predicting radar-to-radar interference.
From the measured data and a supporting literature search, it was concluded that ducting and man-made clutter (building attenuation) should be included in the propagation loss predictions in order to improve the prediction accuracy of radar-to-radar interference and radar frequency assignments. Even though potential multipath wave interference conditions can be identified, to account for this analytically would require and extremely complex antenna and terrain model. Due to modeling inaccuracies, the difference between the predicted and actual radar-to-radar Interference-to-noise Ratio (INR) levels may be as large as 22 dB (2σ standard deviation region). However, INR errors of approximately 25 dB can still result in relatively accurate predictions of interference patterns on the victim PPI display for conditions where mainbeam-to-backlobe antenna coupling predominates. In summary, it was concluded that the analytical radar-to-radar interference techniques used in this investigation can be used to predict interference patterns on the victim radar PPI display with sufficient accuracy to allow assessment of radar band congestion, frequency assignment flexibility, and potential of the band to absorb new users.
