APPENDIX-A
3650 MHz Band Information
Band History
• Historically part of the Fixed Service Satellite (FSS) allocation
• FSS operators are considered “grandfathered” operations and
are provided protection in the form of “exclusion zones”
• About 85 users remain, mostly on East and West Coasts of U.S.
• Over 20 states with no grandfathered operations in effect
• Recently, the FCC allocated 50 MHz of this spectrum (3.65 –
3.70 GHz) for private infrastructure and rural ISP use—not con-
sumer mass deployment
• 3650 MHz is considered a “registered” band. It is neither
licensed nor unlicensed
• Industry Canada rules patterned after FCC rules
Technical Details
• 50 MHz spectrum divided in two bands of 25MHz each
• Lower 25 MHz allows “Restricted protocols,” upper 25MHz
allows “Unrestricted”
• Operation requires registration with FCC database – operators,
all fixed point installations
• EIRP: One watt per-MHz for fixed deployments. 40 mW
per-MHz for mobile operation.
• Industry Canada rules allow “Restricted protocols” across the
entire 50 MHz span.
Exclusion Zones
Maps showing exclusion zones in the U.S. are available online.
Exclusion zones contain grandfathered operations which must be
protected from 3650 MHz interference. At the time of publication, one
such map is available at the following URL:
