1、The Evolution of Mid-Band Mobile Spectrum in the USCopyright 2026 GSMA2/17US Spectrum EvolutionSummary The 800 MHz of spectrum to be assigned in 2034 for MNOs that is outlined in the OB3 Act has aligned the US with current plans of other global technology leaders.However,the US may need more spectru
2、m than this in the longer-term(2035-2040).US mobile operators are making efficient use of mid-band spectrum,achieving good 5G coverage and performance both outdoors and indoors across its largest cities.This is done primarily using 2.5-2.6 GHz(for T-Mobile)and licensed spectrum in the 3.45 GHz and 3
3、.8 GHz bands,which fall within the global 3.5 GHz range at 3.3-4.2 GHz(for AT&T and Verizon).While mobile operators have made efficient use of the 380 MHz available in the 3.5 GHz range four years after its auction,the 1200 MHz made available for unlicensed use in the 6 GHz band remains under-utilis
