Sharing and compatibility studies of High Altitude Platform Station systems in the fixed service in the 38-39.5 GHz frequency range
In this issue
This Report includes the sharing and compatibility studies of High Altitude Platform Station (HAPS) systems in the 38-39.5 GHz frequency range with the Fixed Service (FS), the Mobile Service (MS) and the Fixed Satellite Service (FSS) to which the bands are allocated on a primary basis, and also with the Space Research Service (SRS) in the adjacent band.
