Additional Information

Administrations may consider flexible aggregation of those 250 MHz basic channels for composing wider channels. Administrations wishing to assign traditional FDD duplex channels or blocks, may use the bands 130-134 GHz, 141-148.5 GHz, 151.5-164 GHz and 167-174.8 GHz as paired bands with suitable spacing > 15 GHz.
To protect the Earth Exploration-Satellite Service (EESS) operations in the bands 148.5-151.5 GHz, 164-167 GHz, the unwanted emissions at the antenna port of any FS station in those bands should respect the mask provided in Annex 5.
