Last month we reported on an FCC decision that wrapped up a couple of proceedings relating to three types of specialized radar devices in the 76-77 GHz band: one for vehicle radars, which function as part of automatic braking systems in cars; one for detecting “foreign object debris,” or FOD, on airport runways; and one for tracking aircraft and service vehicles around airport runways and ramp areas.  We noted that the Commission’s order curiously, and uncharacteristically, didn’t announce an effective date for the rule changes.

No problem. According to a notice in the Federal Register, those changes will take effect on September 12, 2012.
