More than $14 billion has been invested across the CBRS stacklicenses, RAN, devices, infrastructure, sensors, and software. Over 420,000 CBRS radio nodes (CBSDs) are in service. The device ecosystem is broad: Apple and Samsung ship n48-capable handsets; industrial and FWA suppliers support n48 CPEs and routers; Ericsson, Nokia, Samsung, JMA Wireless and others provide radio and DAS. This is not a pilot; it is production infrastructure. Refarming would force replacement or retuning of hundreds of thousands of base stations and millions of end devices, plus upgrades to SAS integrations and enterprise control planes.
