Submillimeter amateur radio refers to Amateur radio activity in the sub-millimeter region (275 GHz to 30 THz) of the electromagnetic spectrum. While no international frequency allocations exist for amateur radio in the sub-millimeter region, a number of administrations permit radio amateurs to experiment on Terahertz frequencies. Amateurs who operate in the region must design and construct their own equipment, and those who do, often attempt to set communication distance records on sub-millimeter frequencies.
