CBRS Essential Artifacts Public CDN

CBRS Essential Artifacts – Public Mirror Now Available

The Key Bridge Wireless CBRS CDN is now publicly available for anyone working or interested in the Citizens Broadband Radio Service (CBRS) ecosystem.

The CBRS Essential Artifacts repository is hosted at:
https://cdn.keybridgewireless.com/cbrs/

This lightweight, always-on CDN serves as a convenient mirror of key public-domain reference data, geospatial files, and regulatory artifacts for CBRS deployments, planning, compliance, research, and development.

It contains periodically updated copies of the following public-domain data from FCC and NTIA sources:

• US county boundaries (shapefile zip)
• Current NTIA Dynamic Protection Area (DPA) KML files
• Yearly FCC Equipment Authorization JSON records (2017–2025)
• Periodic Fixed Satellite Service (FSS) protection snapshots (JSON)
• Latest Priority Access License (PAL) channel assignment database (JSON)
• Most recent NTIA Exclusion Zones KML

An HTML index page with direct download links and basic descriptions is available at the root URL.

All files are public domain U.S. government data (or simple derivatives), redistributed here for convenience under the same terms — with the standard "no warranty, verify with official sources" disclaimer.

This is not an official source. Always verify and use the latest data directly from FCC and NTIA for any production, compliance, or regulatory purpose.

Feedback on additional files or improvements welcome.
