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.

Progress on drone, vehicle engines signals Turkey’s independence from foreign suppliers
By: Burak Ege Bekdil ANKARA, Turkey — Two Turkish companies have consecutively reported significant progress toward building indigenous engines that would power locally made drones and armored vehicles. State-controlled company Tusas Engine Industries, or TEI, announced the completion of a program for the design, development and production of an indigenous engine that will power the Anka, a medium-altitude, long-endurance drone developed by TEI's sister company, Turkish Aerospace Industries, or TAI. TEI said it successfully integrated the PD170 engine to the Anka drone. The Anka, with the PD170, will go through flight tests later this year. TEI officials said the company already signed a serial production contract with TAI. The next step will be to win certification for the engine. TEI's general manager, Mahmut Akşit, said the PD170 program aims to end Turkey's dependency on foreign engine suppliers. “A further aspect of the program will be exporting the PD170 to foreign countries,” Akşit said. In 2012, TEI signed a contract with Turkey's procurement authority, then Undersecretariat for Defense Industries (now Presidency of Defense Industries), for the development of the PD170. TEI has a partnership agreement with U.S.-based General Electric. Turkish procurement authorities recently announced the selection of GE for the supply of engines to power the initial batch of the TF-X, Turkey's indigenous fighter jet in the making. The twin-engine TF-X will be powered by either the F110-GE-129 or the F110-GE-132 engine. Turkish officials say the GE engine would be a stopgap solution until “we have built our indigenous engine for the TF-X.” Under the deal, the first prototype of the TF-X and an unknown number of initial batches would be powered by an F110 engine.

Collins Aerospace Broadens Communication Capabilities for USAF U-2 Dragon Lady
Collins Aerospace Systems, a unit of United Technologies Corp. (NYSE: UTX), has been selected by the U.S. Air Force (USAF) to upgrade its fleet of U-2 Dragon Lady aircraft with HF-9087D High Frequency (HF) radios. With a primary mission of reconnaissance, the U-2 will gain the ability to securely transfer Command and Control (C2) data in real-time over HF while still maintaining reliable, clear voice communications beyond line of sight. “In contested environments, HF communications continue to be a reliable backbone to ensure mission success with a low operating cost,” said Troy Brunk, vice president and general manager, Communication, Navigation and Guidance Solutions for Collins Aerospace. “The U-2's upgraded HF will provide robust long-range digital communications capabilities to this platform.” Since 1933, Collins Aerospace has been a leader in HF technology. The company is a supplier of HF systems for the USAF's High Frequency Global Communications System (HFGCS) and provides HF communications on nearly all airlift, tanker and bomber assets used in the Department of Defense today. http://www.asdnews.com/news/defense/2019/09/17/collins-aerospace-broadens-communication-capabilities-usaf-u2-dragon-lady
