DISTRIBUTED RADIO FREQUENCY SPECTRUM SHARING COORDINATION SYSTEM

Systems and methods for allocating radio frequency spectrum. One example system includes a spectrum broker server including a communications interface and an electronic processor. The electronic processor is configured to determine an available radio frequency spectrum allocation. The electronic processor is configured to receive a spectrum request for the available radio frequency spectrum allocation at the communications interface, wherein the spectrum request is associated with a spectrum-consuming entity. The electronic processor is configured to receive, from a plurality of validation nodes, a plurality of votes based on the spectrum request. The electronic processor is configured to determine whether to grant the spectrum request based on the plurality of votes. The electronic processor is configured to, responsive to determining to grant the spectrum request, allocate the available radio frequency spectrum allocation to the spectrum-consuming entity.
