Garmin Offers More Details on Waiver Advocacy

Garmin International provided additional information to the FCC on its request for a waiver of rules for handheld general mobile radio service (GMRS) devices limiting them to one transmission every 30 seconds (see 2310060031). Garmin responded to a North Shore Emergency Association filing, which found an earlier filing on a September meeting of Garmin with FCC staff was inadequate (see 2407260036). “Garmin reiterated [during the meeting] that the data transmissions of its proposed GMRS device will have a reduced duty cycle and less practical effect on users of GMRS devices compared to the digital data transmissions currently permitted under the Commission’s GMRS rules, including by limiting data transmissions to interstitial channels,” said the latest Garmin filing, posted Tuesday in docket 24-7. “Specifically, Garmin is seeking to provide very short (50 milliseconds) digital data transmissions, such as GPS location data, once every five (5) seconds, provided that in non-emergency situations the channel being used has not been utilized for voice communications in the prior 30 seconds,” Garmin said.
