FCC Shouldn't Relax White Spaces Interference Rules Because of ATSC 3.0, Says BitPath

The FCC should reject the Wireless ISP Association’s arguments that ATSC 3.0’s greater capabilities to handle interference mean the FCC should relax interference rules for unlicensed devices operating in the TV white spaces, said broadcaster consortium BitPath in an ex parte filing Friday in docket 20-36. The “most troubling aspect” of WISPA’s stance is the idea “that the capabilities of ATSC 3.0 should be applied not to improve broadcast television service, but rather to give [white spaces device] interests more operating flexibility,” said BitPath CEO John Hane. An interference test performed by WISPA, “skips over too many inconvenient real-world facts to be taken seriously,” Hane said. Both ATSC 1.0 and ATSC 3.0 receivers must be protected from interference because there are currently few 3.0 devices and 1.0 signals are still required, Hane said. “Any conclusions drawn solely from self-serving tests of two devices would be unjustified,” he said. “Technological advances in interference modeling ensures that spectrum, that scarce public resource, is put to its best and highest use,” emailed WISPA CEO Claude Aiken. “The FCC has welcomed those technological advances in interference modeling in multiple other shared spectrum bands. WISPA merely suggests that the FCC should follow suit here as well.”
