Assessment of Compatibility between Global Positioning System Receivers and Adjacent Band Base Station and User Equipment Transmitters

Report ID
TM-20-536
December 07, 2020
Edward F. Drocella Jr., Cou-Way Wang, Nickolas LaSorte
Abstract

This technical memorandum provides the results of a compatibility assessment between terrestrial GPS L1 coarse/acquisition (C/A) code receivers operating in the 1559-1610 MHz RNSS band and terrestrial operations in the 1526-1536 MHz, 1627.5 1637.5 MHz, and 1646.5-1656.5 MHz bands. The Interdepartment Radio Advisory Committee (IRAC) Technical Focus Group (TFG) assessed compatibility between different categories of GPS L1 C/A code receivers and the proposed terrestrial deployment by examining the degradation in carrier-to-noise density ratio (C/N0), loss-of-lock, position error, and increase in acquisition/reacquisition time for GPS receivers.

NTIA Letter to FCC Chairman Regarding T-Band Grant Program

November 23, 2020

This letter explains the views of NTIA about its obligations under section 6103 of the Middle Class Tax Relief and Job Creation Act of 2012 (Act). In NTIA’s view, the Act provides clearly differentiated responsibilities for the Federal Communications Commission (Commission) and NTIA with respect to the reallocation of the 417-512 MHz (T-Band) spectrum - - the Commission is to reallocate and auction the spectrum and NTIA is to administer a grant program with the auction proceeds to cover the affected public safety entities’ relocation costs.

NTIA Plan to Congress on Declassification and Clearances Related to the Communications Supply Chain Risk Information Partnership

November 18, 2020
Abstract

The Secure and Trusted Communications Networks Act of 2019 requires NTIA to establish an information sharing program to ensure that small, rural providers have access to the supply chain risk information they need before they make an investment.  To meet this requirement, NTIA established the Communications Supply Chain Risk Information Partnership (C-SCRIP) in July 2020. Section 8 of the Act also requires NTIA within 180 days to submit a plan to the Committee on Energy and Commerce of the House of Representatives and the Committee on Commerce, Science, and Transportation of the Senate for (i) declassifying material, when feasible, to help share information regarding supply chain security risks with trusted providers of advanced communications service and trusted suppliers of communications equipment or services; and (ii) expediting and expanding the provision of security clearances to facilitate information sharing regarding supply chain security risks with trusted providers of advanced communications service and trusted suppliers of communications equipment or services.

Compatibility of Federal Systems Operating in the 5850-5925 MHz Band with Intelligent Transportation Systems and Unlicensed National Information Infrastructure Devices

Report ID
21-551
October 22, 2020
Edward Drocella, Yang Weng, Michael Ghorbanzadeh, Edison Juleau, Nickolas LaSorte
Abstract

This Technical Report provides details about protection of federal operations in the 5.850-5.925 GHz (5.9 GHz) band from new operations considered by the Federal Communications Commission (FCC) as part of the agency’s comprehensive review intended to allow for the highest and best use of the band. As part of its ongoing effort to accommodate new commercial wireless services, the National Telecommunications and Information Administration (NTIA) worked with agencies that operate federal systems in the band to determine the protections needed to permit new commercial services to operate without causing impact to incumbent operations. To facilitate the FCC’s expeditious review of the record, NTIA already submitted to the FCC a letter setting forth the relevant protection requirements derived from the numerous details provided in this Technical Report.
