FCC KDB publication 388624 D02 v18r09 replaced v18r08 on September 30, 2026. The revision adds PAG item SUBTHZ and a corresponding checklist, removes PAG items OVER6G and UWB15F, and limits UN6GHZ PAG treatment to geofenced variable-power devices. The changes affect how applicants and Telecommunication Certification Bodies determine whether pre-approval coordination with the FCC is required before a certification grant.

Impact

Impact assessment: High. Key reasons: The current guidance directly changes FCC certification workflow for sub-THz, 6 GHz GVP and categories removed from PAG, affecting evidence and TCB processing.

Who is affected?

Radio-equipment manufacturers, FCC grantees, TCBs, accredited laboratories, test engineers, certification consultants and applicants handling sub-THz, 6 GHz or UWB products.

Conclusion:

Replace v18r08 in certification procedures, re-screen open applications against v18r09, use the SUBTHZ checklist where applicable, and confirm whether UN6GHZ is required only for GVP devices. Coordinate any classification uncertainty with the responsible TCB before filing.
