The FCC is looking at the possibility of using the 3.7–4.2 GHz band, currently used for NOAAPort transmissions, for a broader range of services including wireless broadband.
Receive-only Fixed-satellite Service (FSS) and Fixed Service (FS) sites are not required to register with the FCC. For this reason, it is unknown how many existing sites are receiving data using this frequency. Without this information, it is difficult to assess the impacts of expanding services in the 3.7–4.2 GHz frequency band.
To understand the current landscape, the International Bureau opened a 90-day filing window for applications to license or register existing earth stations in the 3.7–4.2 GHz band. Stations that were constructed and operational as of April 19, 2018, may file. The filing window closes on July 18, 2018. Applicants must file electronically through IBFS on FCC Form 312 Main Form and Form 312 Schedule B, remit the statutory application filing fee, and provide any additional information required by applicable rules. See the last few paragraphs of the notice (linked below) for details.
Using IBFS link under FILE contains site instructions. The red box indicates the link to create the FRN.
The Bureau also placed a temporary freeze on applications for new or modified FSS earth stations and fixed microwave stations in this band.
For our NWS members, please note that the NWS is in the process of registering their antennas.
More information is contained in the FCC Public Notice DA-18-398.
