Description (excerpt)

NOTICE OF INTENT TO SOLE SOURCE The Defense Information Systems Agency/Defense Information Technology Contracting Organization intends to negotiate a sole source contract with Peraton, Inc. A sole source Justification & Approval document is being coordinated and, upon approval, a copy of it will be posted here on SAM.gov to comply with the public display requirements of FAR 6.301. The proposed contract action will continue providing support to facilitate the completion of the 3.45 GHz Engineering Support for Enduring Coordination (3-ESEC) for the 3450 – 3550 MHz band effort. BACKGROUND: In 2020, the White House and Department of Defense (DoD) established the America’s Mid-Band Initiative Team (AMBIT) to make 100 MHz of contiguous mid-band spectrum available for commercial 5G. The Federal Communications Commission (FCC) subsequently authorized flexible-use licenses in the 3450–3550 MHz band (3.45 GHz band) and conducted Auction 110 in October 2021, offering 4,060 licenses nationwide. The band includes Cooperative Planning Areas (CPAs), which require coordination with DoD systems, and Periodic Use Areas (PUAs), where commercial access may be restricted during DoD operations. To support spectrum sharing, Portfolio Acquisition Executive (PAE) Command, Control, Communications, and Engineering (C3E) developed the 3.45 GHz Transition Plan, including an interim coordination portal and a future dynamic coordination system. In January 2022, Peraton was awarded the AMBIT Engineering Support for Initial Coordination (AESIC) task order to provide engineering analysis and manage coordination requests between DoD and commercial licensees. In April 2025, a follow-on 3.45 GHz Engineering Support for Enduring Coordination (3-ESEC) task order was awarded to Peraton and ends in May 2027. Since formal coordination began in October 2022, the AESIC/ESEC team has processed 3,192 coordination requests, 573,877 sectors, and delivered 2,080 results letters from commercial licensees. Because DoD systems will continue operating in the band, ongoing engineering support is needed to coordinate spectrum use between Military Departments and commercial licensees in CPAs and PUAs nationwide. Since October 2022, Peraton has supported more than 200 coordination meetings with commercial licensees and DoD stakeholders, building trusted relationships and a deep understanding of stakeholder priorities, operational requirements, and evolving mission needs. Primary objectives include: Manage and ov …
