Pentagon clears 100 MHz of spectrum for 5G development

The Pentagon has cleared 100 megahertz (MHz) of contiguous mid-band spectrum to be used for commercial 5G following a 15-week review, determining that they can share that bandwidth while minimizing impact on military radars.

While that 3450-3550 MHz mid-band spectrum is highly desired by commercial 5G developers, it's been historically used by the military for critical radar operations for air defense, missile and gunfire control, counter-mortar, bomb scoring, battlefield weapon locations, air traffic control, and range safety.

But now, leaders from the Department of Defense say the Pentagon can continue using the spectrum for those purposes while making it available for commercial development. DoD Chief Information Officer Dana Deasy said the department will move toward sharing most of that spectrum without limits while setting up a Spectrum Relocation Fund Transition Plan to minimize risks.

“DoD is proud of the success of the [America's Mid-Band Initiative Teams (AMBIT)] and is committed to working closely with industry after the FCC auction to ensure timely access to the band while protecting national security,” Deasy told reporters Aug. 10.

The White House and Department of Defense established AMBIT to free up spectrum for 5G development quickly back in April. Over a 15-week period, the working group was able to bring together 180 subject matter experts, and ultimately were able to identify 100 MHZ of spectrum used by the military that could be safely shared with commercial 5G efforts.The decision expands the amount of connected mid-band spectrum open for 5G development to 530 MHz.

The Federal Communications Commission will auction off the spectrum. One government official said action was expected by the end of this fiscal year.

    Pentagon’s central AI office wants to standardize its acquisition process

    Andrew Eversden WASHINGTON — The Pentagon's top artificial intelligence office released a request for information Aug. 28 outlining interest in establishing a new acquisition approach for standardizing the development and procurement process for AI tools. According to the solicitation, the Joint Artificial Intelligence Center is “considering” starting a competition for a 501(c) nonprofit manager or managers of its prototype “Artificial Intelligence Acquisition Business Model” that looks to use other transaction authorities to more quickly purchase AI products. The JAIC's prototype business model could deliver “AI capabilities through meaningful market research/front-end collaboration and optimal teaming arrangements of both traditional and non-traditional companies for AI product procurement,” the RFI said. If the plan moves forward, the JAIC would also “explore the possibilities of using the model to enable agile AI acquisition processes to the DoD at scale.” The JAIC is the Defense Department's main hub for artificial intelligence and is responsible for increasing adoption of AI across the department. It works with the services and combatant commands to develop AI tools that have practical use. To meet the military's needs, the JAIC uses the traditional government contracting process, known as Federal Acquisition Regulation-based contracts, and works with the General Services Administration, the Defense Information Systems Agency and the Defense Innovation Unit. The traditional acquisition strategy currently being used is unlikely sufficient enough to help the JAIC carry out its mission, the RFI stated. “To scale this strategy to other DoD service requirements or respond to emergent requirements such as COVID-19 is challenging and may not be the most efficient use of acquisition tools,” the RFI read. “The JAIC will therefore prototype a new AI Acquisition Business Model to assess the potential for non-FAR-based contracts mixed with FAR-based contracts to meet JAIC requirements.” JAIC's goals are to streamline awards while maintaining flexibility between FAR and non-FAR awards, and to maximize competition while minimizing restrictions, the RFI explained. The JAIC recently awarded major contracts through DISA and GSA. In May, it awarded a five-year contract with an $800 million ceiling to Booz Allen Hamilton through the GSA for its new joint war-fighting national mission initiative, though JAIC officials have continuously noted that the value of the contract won't hit $800 million. https://www.c4isrnet.com/artificial-intelligence/2020/09/01/pentagons-central-ai-office-wants-to-standardize-its-acquisition-process/
