    Ligado Exemplifies Broken US Spectrum Management: Industry Experts

    "There's a lot of inefficiencies in the process. But it's basically a fight, with each community pressing its case to its own regulatory body," says Jennifer Warren, Lockheed Martin's vice president for technology, policy and regulation. By THERESA HITCHENSon September 11, 2020 at 2:19 PM WASHINGTON: The FCC's controversial decision to let Ligado proceed with its 5G wireless network over fierce DoD objections is just one more example of the broken state of the US regime for managing spectrum, industry experts say. “There's a lot of inefficiencies in the process. But it's basically a fight, with each community pressing its case to its own regulatory body,” Jennifer Warren, Lockheed Martin's vice president for technology, policy and regulation, told the Secure World Foundation (SWF) Summit for Space Sustainability this morning. This has led a little-known but highly influential government advisory panel to recommend a series of options for overhauling the US regulatory system — including the creation of a new agency — to empower a single entity to decide how to balance skyrocketing demands for bandwidth as availability dwindles. “[T]he United States' current approach for managing the use of spectrum is no longer effectively serving the needs of the entire stakeholder community and would benefit from reform,” the Commerce Spectrum Management Advisory Committee (CSMAC) says in a recent report. “Moreover, with the increased use of spectrum by all stakeholders, we agree that issues around allocations, spectrum-sharing and band adjacencies will need to be handled with both speed and skill to ensure that the US is making the most of its critical national resources.” CSMAC, created by the Commerce Department in 2004, comprises spectrum policy experts outside the government. The report, said Warren, who was one of the authors, was designed to kick start what many in industry see as an urgent debate about how US spectrum policies can accommodate a rapidly changing technological environment — particularly the emergence of 5G networking, which has the potential to revolutionize global communications. Currently, two different US government bodies have regulatory control of spectrum by different users with very different priorities. The FCC governs use of spectrum by the commercial telecommunications industry (both terrestrial and space-based). The Commerce Department's National Telecommunications and Information Administration (NTIA) governs access to bandwidth for government agencies, including DoD. This bifurcation was established by the 1934 Communications Act and remains in place despite massive upheaval in technology and spectrum use since then. The Ligado case underscores that, despite a 2003 memorandum of understanding between FCC and NTIA that pledges them to coordinate, there is no requirement that they reach consensus, Warren explained. Indeed, there isn't even a requirement that a disputed decision by the FCC, such as on Ligado, must be escalated for adjudication. Instead, the FCC has “unilateral decision-making power.” Indeed, the CMSAC report stresses that: “There are no statutory federal or non-federal bands. All such federal, non-federal, and shared band allocations result from agreements between NTIA and the FCC.” As Breaking D has reported extensively, DoD, the Intelligence Community, the Transportation Department, the FAA and even the Agriculture Department — not to mention congressional defense committee leaders — have charged that the Ligado plan will create serious interference to GPS receivers used both by commercial/civil users and US troops. Those concerns have been echoed by a number of commercial users groups, from airline pilots to construction workers to farmers. Not only does the current regulatory system block rational decisions on spectrum sharing among types of users, it also creates problems for the United States in its negotiations with other countries on spectrum usage at the International Telecommunication Union (ITU), Kimberly Baum, vice president of regulatory affairs at Echostar Corp., told SWF. The ITU is responsible for setting rules about how spectrum is used by whom at the international level via its Radio Regulations and frequency allocation tables — something that particularly affects satellites that usually serve more than one nation. Every three to four years, ITU holds a World Radiocommunication Conference (WRC), the next of which is scheduled for 2023, where the 193 member nations propose changes to spectrum usage. The State Department is charged with bringing the US position on changes, developed by the FCC and NTIA, to Geneva. Baum, who also is co-chair of the Satellite Industry Association's (SIA) regulatory working group, explained that because the NTIA and FCC each works with its own constituents, sometimes for years, to craft those WRC proposals, differences between them are not resolved until the last minute — if at all. And this loses the time the US needs to try to convince other countries to back its views. (Indeed, as Breaking D readers know, a number of US lawmakers and policy experts are worried that internal US disarray on spectrum management rules for 5G is effectively ceding power at the ITU to China.) “I would love to see a concerted effort to make decisions that meaningfully accommodate multiple services and technologies in a more fair, thoughtful way,” Baum said. Any changes to the current regulatory system would require congressional action to rewrite the Communications Act, and re-allocate statutory authorities, said Warren. A next step, she said, might be for the Government Accountability Office (GAO) to do a study of the issues and make recommendations to Congress. https://breakingdefense.com/2020/09/ligado-exemplifies-broken-us-spectrum-management-industry-experts

  • The Marine Corps wants to protect its Hornets from GPS jammers

    The Marine Corps wants to protect its Hornets from GPS jammers

    By: Shawn Snow The Corps is looking to install antennas in its F/A-18 C/D Hornets to help the aircraft defeat GPS jammers. In a request for information posted in early June by Naval Air Systems Command, or NAVAIR, the Corps wants to install the anti-jam antennas known as the Air Navigation Warfare Program, or NAVWAR, in 120 of the legacy Hornets. The anti-jamming antenna “provides Global Positioning System (GPS) protection for Naval Air platforms by allowing for continued access to GPS through the use of Anti-Jam (AJ) Antenna Systems designed to counter GPS Electronic Warfare threats from intentional and unintentional interference,” Michael Land, a spokesman for NAVAIR, told Marine Corps Times in an emailed statement Tuesday. The development comes as U.S. aircraft have faced mounting electronic warfare attacks against aircraft in Syria. Army Gen. Tony Thomas, the commander of U.S. Special Operations Command, told audience members at a conference in April that adversaries were trying to bring down AC-130 gunships in Syria using electronic warfare, or EW. “Right now in Syria, we're in the most aggressive EW environment on the planet, from our adversaries,” Thomas said. “They're testing us every day, knocking our communications down, disabling our AC-130s, et cetera.” The Corps is amid an overhaul of its forces and equipment to prepare for a potential fight with near-peer adversaries like Russia and China. Both countries boast an impressive array of electronic warfare capabilities. Russia has been using the Syrian battlefield to hone its EW skills. The top Marine has oft repeated the threats posed to GPS systems from rising adversaries and says the Corps needs to be prepared to fight in GPS denied environments. The F/A-18 is the Corps' bridging aircraft as it moves to the new high-tech F-35. As the Corps transitions the older legacy Hornets are undergoing a service life extension, meaning the aircraft are being updated to handle the modern battlefield. “Installation in F/A-18 A-D helps ensure continued mission capability as the service life of the aircraft is extended and facilitates supportability by using more common equipment,” Land said. The Navy and the Marine Corps already use the anti-jamming GPS antenna in a number of airframes, according to Land. “Typical installations replace a platform's existing GPS antenna with a NAVWAR antenna and separate antenna electronics, while leaving a platform's GPS receiver in place,” Land added. The Corps expects the F/A-18 to be in sunset by 2030. As the Corps moves to the F-35 and phases out its Hornets, the legacy fighters will consolidate on the West Coast by 2018 with the exception of VMFA (AW)‐242, which will remain aboard the Corps' air station at Iwakuni, Japan until it transitions to the F-35 in 2028, according to the Corp's 2018 aviation plan. https://www.marinecorpstimes.com/news/your-marine-corps/2018/07/10/the-corps-wants-to-protect-its-hornets-from-gps-jammers/
