Today, over 60 commercial interests including major airlines — American, Delta, Frontier, JetBlue, Southwest and United — filed in support of a Commerce Department request to keep Ligado Networks from deploying any network equipment until the US government can resolve interference concerns with their plans. As the manager of federal agencies’ airwaves, Commerce petitioned the Federal Communications Commission to reconsider its April decision to allow Ligado to operate in airwaves that the Department of Transportation, the Federal Aviation Administration and these commercial interests believe will cause interference to government and commercial users in airwaves nearby. NTIA also petitioned the FCC to stay the Ligado order while the request is considered, which is the subject of the letter attached.
