2021/03/10 Dozens of parties cite evidence of harmful interference and vast economic harm that FCC ignored in favor of dubious 5G marketing claims Dozens of private-sector interests will file Petitions for Reconsideration of the Federal Communications Commission’s (FCC) recent order to allow Ligado Networks to rezone its satellite spectrum holdings for terrestrial mobile use and “flip” them for a profit, according to the Washington, D.C.-based communications firm Glen Echo Group. Petitioners will ask the FCC to reconsider its decision, which has generated widespread opposition within the administration, on Capitol Hill and from other aviation and satellite spectrum users. Petitioners include: Airline Pilots Association Association of Equipment Manufacturers Aviation interests (including the Cargo Airline Association, the International Air Transport Association and Airlines for America) Iridium Communications Lockheed Martin Trimble RNT Foundation The petitioners argue the FCC’s Order ignored or improperly disregarded the great majority of evidence, including technical analyses submitted by parties showing harmful interference, and relied instead on “easily disproven claims that Ligado will provide a so-called 5G service,” the Glen Echo Group stated in a press release. “The L-band is not included in any internationally recognized 5G standard, the spectrum is not harmonized regionally or globally for 5G, FCC’s 5G FAST Plan does not include Ligado or L-Band spectrum nor does the company have enough contiguous spectrum,” the release stated. Airlines for America. “Airlines for America (A4A) strongly supports a broad industry coalition that has led at least 32 U.S. Senators from both sides of the aisle to urge the FCC to stay and reconsider granting Ligado Networks’ petition to repurpose critical frequency spectrum for ‘5G’ terrestrial communications services. The FCC’s rushed order in April ignored testing protocols intended to protect critical users likely to be impacted, including aviation uses of Global Positioning Systems (GPS) for navigation, and satellite communications. Beyond industry opposition, the U.S. Department of Defense also strongly opposed the FCC’s action. “A4A is joining other industry constituents in directly petitioning the FCC to reverse its course, the effects of which could impact the safety of the flying public and impact operations, especially harmful outcomes in the recovery period following the COVID-19 pandemic.” Aerospace Industries Association. The association represents more than 300 companies. “Uninterrupted access to GPS is essential not only for our industry, but also for the American people, our national security, and the strength of the U.S. economy. This access is now threatened by the FCC’s decision to grant Ligado Networks’ application, despite years of evidence and the concerns outlined by several federal agencies about potential interference. With this motion, we are banding together to urge the FCC to reconsider this decision and allow safety and data to drive their decision-making on spectrum.” The International Air Transport Association (IATA), which represents some 290 airlines or 82% of global traffic said, “Approving Ligado’s spectrum for 5G poses a strong risk of interference with GPS signals, including the potential interruption of GPS signals at low altitudes. The FCC should reverse this decision.” Air Line Pilots Association (ALPA). President Capt. Joe DePete said, “Throughout its report and order, the FCC uses words like ‘possible’ and ‘feasible’ when talking about whether Ligado can operate. These are not the words you would want to hear your Captain use when talking about successfully completing your flight the next time you are sitting in the cabin. Aviation requires certainty and guaranteed performance from its systems. The FCC’s hasty, arbitrary, and incorrect decision will set a disastrous precedent that will impede ongoing work on spectrum sharing. The Ligado decision must be reversed immediately.” Aviation Spectrum Resources Inc. “In jointly filing a petition for reconsideration of the FCC’s recent decision on Ligado Networks’ proposal, ASRI joins the wider aviation community in expressing our view that the decision is based on a fundamentally flawed interpretation of the data that have been presented to the Commission. Among other deficiencies, the FCC’s decision ignores the FAA’s reservations cited by the Department of Transportation, having implications for many low-level aircraft operators including helicopters and UAVs. The FCC Order also seems to acknowledge the mounting evidence that aviation safety satellite communications will receive interference, but it relies on the completion of private negotiations to resolve these questions while giving Ligado a green light to proceed, rather than requiring specific mitigations itself. ASRI believes the FCC should revisit its decision in conjunction with aviation experts to ensure the safety of air transport, medivac and other essential aviation operators are not affected by this decision.” Iridium Communications. CEO Matt Desch said, “The FCC’s Ligado action prioritizes economic windfalls to a few speculators over safety of life, national security and important private sector companies whose customers would be most upended by their harmful interference.” RNT Foundation. President and Director Dana A. Goward said, “The FCC treated this like a commercial communications issue instead of a decision about safety-of-life navigation. They didn’t even consider the overall cost to the public in lost lives and property.” In addition to private sector interests, 14 federal agencies and numerous Republican and Democratic members of Congress oppose the FCC’s decision in favor of Ligado.
