What Happened?

If you make or sell wireless devices using ultra-wideband (UWB) technology, a short-range radio standard found in car key fobs, asset trackers and smartphones, getting federal approval could soon become faster and cheaper. The Federal Communications Commission (FCC), the agency that sets rules for wireless devices in the U.S., proposed a broad update to its UWB rules on Nov. 2, according to a Legis1 review of the FCC's proposed rulemaking. ​

  • New device category: A new location-sensing category would cover keyless entry, vehicle ranging and precision-tracking products.
  • Toy ban lifted: The current rule bars UWB use in toys; the proposal would remove that prohibition, which the FCC first said it might revisit in 2002 but never did.
  • Coordination paperwork dropped: Operators of UWB imaging systems currently must file operational details with the FCC and wait 15 business days before use; the proposal would eliminate that requirement.

Why Does it Matter to Me?

The FCC estimates the changes would save device makers and other industry participants about $27,000 a year by cutting roughly five waiver applications annually, and save the agency itself about $44,000 a year in staff review time.

The FCC says it has been operating under "regulation by waiver," and the conditions it granted repeatedly since 2004 were never incorporated into its rules. The agency also says it has no record of the advance coordination paperwork it requires for imaging systems ever being used to address an interference complaint or triggering a follow-up investigation.

Both Sides, Now

Supporters of looser rules include the auto and tech industries: Robert Bosch LLC filed a petition for these changes on June 18, 2019, more than seven years before the FCC published the proposal, and a coalition that includes the Alliance for Automotive Innovation filed a second petition in December 2025.

Opponents argue that relaxing UWB restrictions could increase harmful interference to GPS and aircraft navigation systems. A study in the U.S. Department of Transportation research repository tested how UWB transmissions affect GPS accuracy and receiver loss of lock, including with an aviation GPS receiver, and it provides a technical basis for concern that UWB can disrupt GPS reception. FlightGlobal reported that United Airlines disclosed preliminary tests in which UWB transmissions were associated with failures in aircraft collision-avoidance and instrument-landing systems.

The FCC is seeking technical evidence on whether more flexible UWB rules could increase interference risks for satellite navigation, radar altimeters and weather radars.

What Happens Next?

Public comments on the proposed rule are due Dec. 2, and reply comments are due Jan. 4, 2027. The FCC is also seeking comment on whether to create a separate device class for artificial intelligence-enabled UWB applications, including robots, drones and autonomous vehicles, but has not yet written proposed rules for that class. None of the proposed changes take effect unless the FCC adopts a final rule.
