The Federal Communications Commission (FCC) has launched a significant UWB rules update aimed at modernizing the regulatory framework for unlicensed Ultra-Wideband technologies in the United States.
On September 30, 2026, the FCC adopted a Notice of Proposed Rulemaking (NPRM), identified as FCC 26-66 / ET Docket No. 26-245. The proposal reviews rules originally established in 2002 and considers changes intended to better reflect current UWB technologies and applications.
UWB supports a broad range of consumer, automotive, industrial, and public safety products. These include digital key fobs, tracking systems, collision-avoidance radar, access-control systems, and specialized imaging equipment.
What the FCC UWB Rules Update Proposes
The FCC proposal seeks to modernize several elements of the existing UWB framework.
First, the Commission proposes updating UWB transmitter definitions that no longer reflect how modern devices operate. Additionally, it plans to revise procedures used to evaluate potential interference with other unlicensed spectrum users.
The NPRM also proposes a new category of UWB devices. This category would support emerging applications such as AI-enabled or super-intelligence-enabled sensing, advanced spatial ranging, and modern access-control systems.
Importantly, the FCC is also examining regulatory issues that manufacturers have repeatedly addressed through individual waiver requests.
Under the existing framework, some newer UWB technologies do not fit easily within legacy technical requirements. As a result, manufacturers may need FCC waivers before bringing those products to market.
For certain door-unlocking UWB products, the FCC noted that providers waited an average of approximately six months for approval.
Potential Impact on FCC Product Authorization
From a compliance perspective, the proposal could create a clearer technical pathway for future UWB products.
Instead of relying as heavily on individual waivers, the FCC intends to consider standardized requirements that better accommodate newer UWB technologies. Consequently, manufacturers of short-range devices, automotive electronics, wearables, tracking products, and specialized imaging equipment should follow the proceeding closely.
However, the NPRM represents a proposed rulemaking, not a final regulatory change. Companies should therefore continue following the current FCC requirements while monitoring the proceeding.
Public comments will be due 30 days after publication of the NPRM in the Federal Register. Reply comments will follow 60 days after publication.
Spectrum Use Remains Unlicensed
The proposal does not introduce a spectrum reallocation.
UWB devices would continue operating on an unlicensed, shared-spectrum basis across existing spectrum bands. The FCC’s proposal instead focuses on definitions, technical restrictions, interference evaluation procedures, and authorization pathways.
Therefore, compliance teams should focus primarily on potential changes to technical requirements and the FCC equipment authorization process rather than changes to spectrum licensing.
Preparing for the Proposed Changes
Manufacturers developing UWB-enabled products for the United States should monitor ET Docket No. 26-245 as the FCC evaluates comments and develops the next stage of the proceeding.
The UWB rules update could ultimately reduce reliance on waivers and provide more predictable compliance pathways for emerging technologies. Nevertheless, specific requirements will depend on the outcome of the FCC rulemaking process.
