Spectrum sharing regulations: US (FCC/CBRS), EU (LSA), India (DoT), Japan (local 5G)

US FCC CBRS Approach

The United States pioneered dynamic spectrum sharing through the CBRS framework, allowing enterprises to deploy private 5G in the 3.5 GHz band without traditional spectrum auctions. The FCC certified multiple SAS administrators including Google and Federated Wireless to manage the ecosystem. This market-driven approach created a thriving private 5G ecosystem with over 300,000 deployed CBSDs. The model influenced global regulators but its specific implementation — county-level PAL auctions, dual CBSD categories, and real-time SAS coordination — remains unique to the US regulatory environment.
