FCC Rules Clear That Ligado Must Prevent Harmful Interference, Iridium Says

Assurances that Ligado is providing the FCC about being open to tighter out-of-band emission limits (see 1611030049) don't change that the company's proposed terrestrial operations would generate excessive out of band emissions that would interfere with Indium's operations in adjacent spectrum, Iridium said in a filing Wednesday in docket 12-340. It said Ligado's technical response to Iridium cherry-picks issues from non-similar FCC proceedings and it said its own assumptions line up with the Commerce Spectrum Management Advisory Committee final report issued in 2013, in which Ligado was a major participant. Iridium also said Ligado's legal arguments fall short and that the company is ignoring Section 25.255 of rules, which puts on Ligado an obligation to prevent harmful interference. Ligado didn't comment.
