In plain terms
Some of the radio frequencies being considered for beaming power down from space are the same frequencies already used by military airfield equipment worldwide, which makes it harder to pick a site.
The claim as recorded
The same 2019 assessment notes that several of the radio frequencies proposed for space-based solar power beaming, specifically 5.8 GHz, 35 GHz and 94 GHz, are already in use at military airfields around the world, which complicates siting for remote military installations.
Scope and limits
does not state how many airfields, which countries, or the resulting interference margin; does not address civil (non-military) spectrum users or ITU allocation status, which are covered by other layers in the register.
What it assumes
No assumptions are recorded against this claim.
Where it comes from
"Many of the RF frequencies considered for space solar (5.8 GHz, 35 GHz, 94 GHz) are in use at military airfields around the world, complicating the situation for many remote installations." (SRC-025, PDF page 33, item 8 "Spectrum is not allocated for RF power beaming")
Basis: frequency bands only, no interference margin or geographic count given
