Lower 37 GHz Band and Use of Spectrum Bands Above 24 GHz for Mobile Radio Service

In this document, the Federal Communications Commission (Commission) makes available 600 megahertz of high-frequency spectrum for flexible fixed and mobile use by establishing a mechanism for access to the 37-37.6 GHz band (Lower 37 GHz band). This spectrum, which is shared between non-Federal and Federal operators, can be used for fixed wireless broadband, Internet of Things (IoT), or other innovative services. Crafted in collaboration with the National Telecommunications and Information Administration (NTIA) and with input from the Department of Defense (DoD), this new regime provides access to a block of millimeter wave spectrum with low barriers to entry.
