Successfully Clearing the C-band Spectrum
Clearing 300 MHz of C-band spectrum is a monumental technical, operational, and commercial task that will take close coordination and cooperation of our customers and their downlink or affiliate earth stations. Intelsat is committed to working with our customers and affected earth stations to ensure the same or better quality of service throughout the clearing process.
The overall schedule for the clearing effort is based on the Accelerated Relocation phases outlined in the FCC’s Report & Order.
In order to meet the Phase I Accelerated Relocation Deadline, Intelsat must repack any existing services and relocate associated Incumbent Earth Stations throughout the contiguous United States into the upper 380 megahertz of the C-band (3820-4200 MHz), and also provide passband filters to block terrestrial signals from the 3700-3820 MHz band to associated Incumbent Earth Stations in 46 of the top 50 Partial Economic Areas (PEAs) by December 5, 2021.
In order to meet the Phase II Accelerated Relocation Deadline, Intelsat must repack any existing services and relocate associated Incumbent Earth Stations throughout the contiguous United States into the upper 200 megahertz of the C-band (4000-4200 MHz), and provide passband filters to block terrestrial signals from the 3700-4000 MHz band to all associated Incumbent Earth Stations in the contiguous United States by December 5, 2023.
On September 30, 2021, Intelsat filed an updated Transition Plan with the FCC. The Transition Plan filing describes in detail our approach to clearing the spectrum, the various bodies of work required, and the processes we expect to follow with our customers, their downlink or affiliate earth stations and other stakeholders. Intelsat updated its Transition Plan primarily to bring current the list of claimed incumbent earth stations and to also incorporate the necessary changes from the FCC’s updated Incumbent Earth Station List, published on September 15.
The customer specific migration plans can be found in Section 6 of Intelsat’s Transition Plan and is updated in each of Intelsat’s Quarterly Status Reports. An Excel version of the latest customer migration plans can be downloaded here (Updated October 8, 2021).
Intelsat continues to perform outreach to earth stations operators to confirm whether or not they receive Intelsat services via satellite and to gather additional technical and operational details that will allow Intelsat to scope and plan the required work to transition each Incumbent Earth Station that Intelsat claims as included in Intelsat’s Transition Plan as a part of this process. Intelsat claims an Incumbent Earth Station when it has confirmed that it receives services from an Intelsat satellite. Intelsat will publish an updated list of claimed Incumbent Earth Stations, as well as highlight any changes in that list, in each Quarterly Status Report filing with the FCC. Intelsat’s latest Quarterly Status Report was filed on September 30, 2021.
The table below includes the service transitions that are currently underway, including the type of change, destination transponder and the target completion date of the dual illumination period.
Intelsat is actively reaching out to eligible downlink or affiliate earth stations of customers that are undergoing compression, polarity and/or satellite changes to offer transition support. If you require assistance and have not yet been contacted, please email us at CBandInfo@intelsat.com.
The table below includes the service transitions that are scheduled to start dual illumination within the next 90 days. Customers will inform their downlink or affiliate earth stations of the details associated with each planned transition in accordance with the contracted change notification period.
