DA 26-226 Released: March 9, 2026 OFFICE OF ENGINEERING AND TECHNOLOGY SEEKS COMMENT ON THE PETITION OF DURIN, INC. FOR WAIVER OF SECTIONS 15.519(A) AND 15.519(A)(2) OF THE COMMISSION’S RULES ET Docket No. 26-58 Comment Date: April 8, 2026 Reply Comment Date: April 23, 2026 By this public notice, we seek comment on a request by Durin, Inc. (Durin) on February 2, 2026 to waive Section 15.519(a) and 15.519(a)(2) of the Commission’s rules to permit Durin to certify and market its “Door Manager” security system that contains an ultra-wideband (UWB) transmitter operating in the 6-10 GHz band. Durin, Inc. Request for Waiver of Section 15.519(a) and 15.519(a)(2) of the Commission’s Rules, ET Docket No. 26-58 (filed Feb. 2, 2026) (Durin Waiver Request). Durin states that the Door Manager works as a smart external access reader that pairs with a user’s existing smart lock that is installed on a door to monitor and control access. Id. at 3. The Door Manager uses Bluetooth Low Energy (BLE) to coordinate and create a secure and authenticated channel of communication between a user device (e.g., a mobile phone) and a Durin reader. Id. Once authentication is complete, the Door Manager starts a UWB ranging session to determine if the conditions for entry have been met. Id. Section 15.519(a) of the Commission’s rules contains provisions for UWB devices that are relatively small and are primarily handheld while being operated and do not employ a fixed infrastructure, and Section 15.519(a)(2) prohibits the use of antennas mounted on outdoor structures or any fixed outdoor infrastructure. 47 CFR § 15.519(a) and (a)(2). Durin argues that grant of its waiver would not undermine the intent of the rule and will both enhance physical security systems and permit advanced spectrum technology to make security systems more accessible and user-friendly. Durin Waiver Request at 2 and 5-7. We seek comment on Durin’s Waiver Request. To develop a complete record on the issues presented by this request, this proceeding will be treated, for ex parte purposes, as "permit-but-disclose" in accordance with Section 1.1200(a) of the Commission's rules, subject to the requirements under Section 1.1206(b).
