1. Why is 5G important?
The next generation of mobile communications technology, 5G, will bring ground-breaking services to consumers and businesses and will be one of the most important drivers of innovation and economic growth over the next two decades, generating millions of new, high-paying jobs. 5G will be able to support millions of devices at ultrafast speeds and transform the lives of people by connecting them faster and better than ever before with extended mobile broadband reach. Industries on 5G networks will be able to quickly compile and compute data and become more efficient and effective in their daily operations. In the healthcare and security sector, mission-critical services will be carried out in real-time response time.

2. How does C-band spectrum relate to 5G?
In order for 5G to be deployed, U.S. wireless operators need access to the C-band, a band of spectrum with the right balance of coverage and capacity to facilitate 5G adoption throughout urban, suburban, and rural America. However, the C-band is currently used by satellite operators serving U.S. broadcasters and programmers to provide TV and radio to nearly 120 million American homes, as well as other critical data transmission services. Therefore, the FCC has worked with satellite operators to develop a plan to vacate a portion of this spectrum for use by 5G wireless operators while migrating current customers to a new solution. 

3. How will C-band spectrum be cleared for 5G?
The FCC spent two years carefully developing a plan to clear 280 MHz of C-band spectrum for 5G mobile services (plus a 20-MHz guard band) in the contiguous United States (CONUS) as early as December 2023, with a portion of that spectrum becoming available as early as December 2021. To deliver on the clearing milestones set out in the FCC’s Order, SES will procure and launch satellites to provide necessary capacity for our existing customers and begin filtering tens of thousands of earth station antennas throughout the United States to prevent interference from new 5G services. 

4. Will SES be hiring American companies to support the C-band clearing and transition?
Yes. SES is helping put America to work by procuring from businesses across the U.S. the services and equipment needed for the C-band transition. SES will make substantial investments with U.S. companies in the transition process. SES is already working with a number of small American businesses, including Montana-based Superior Satellite Engineers, Arizona-based ATCi, and Michigan-based Viking SatCom. SES will shortly publish an RFP for installation and implementation support from U.S. companies. These companies will hire U.S.-based filter and antenna equipment installers, creating additional opportunities for employment throughout the U.S. 

5. Since the FCC’s Order was announced, what has SES been doing in order to meet the deadlines?
SES has a team of engineers, operations specialists and technicians dedicated to clearing the identified spectrum within the FCC’s accelerated timelines. This team is working diligently to develop the implementation plan that will be submitted in June 2020 and to put all of the necessary infrastructure in place to get the clearing done quickly and smoothly.

6. Will COVID-19 impair SES’s ability to meet the accelerated clearing deadlines?
SES is designing its clearing process to account for the challenges of the pandemic and does not foresee delays in its efforts to meet the Order deadlines. We are monitoring the effects of the pandemic on our suppliers and will provide an update to the FCC if there are any significant developments. SES remains committed to meeting the clearing milestones set out in the Order.

On February 28, 2020, the FCC adopted a Report and Order that established an accelerated timeframe for eligible satellite operators to clear services from the lower C-band spectrum (3700-4000 MHz) in the contiguous United States.  While we have provided some details about the Report and Order in these responses, we recommend that you review the Report and Order.

1. What are the accelerated clearing deadlines?

  • December 5, 2021: “Phase I deadline” – The lower 120 MHz of spectrum must be cleared and filters distributed to allow terrestrial service in 46 of the top 50 PEAs (Partial Economic Area, similar to a metropolitan area) 
  • December 5, 2023: “Phase II deadline” – Full CONUS clearing of the lower 300 MHz of spectrum for accelerated relocation payment
  • December 5, 2025: “Relocation Deadline” – Satellite operator “sunset” (i.e., loss of primary protection and right to relocation costs)

2. Can I continue receiving C-band services in the 3.7-4.0 GHz band after the December 5, 2025 deadline or accelerated clearing deadlines within CONUS at my own risk of interference from 3.7 GHz Services?
No.  Regulations prohibit the transmission of C-band satellite services in the 3700-4000 MHz band for purpose of receipt within CONUS after the afore-mentioned deadlines.

3. How can an earth station operator confirm that its earth station is an Incumbent Earth Station?
An earth station operator should consult with the FCC to confirm if its earth station is an Incumbent Earth Station.  The FCC is expected to post a list of all Incumbent Earth Stations by late Summer 2020, with a period afterwards for comment.  But, before that, an earth station operator can search in the FCC’s database (IBFS) or contact the FCC directly to determine if its earth station(s) are Incumbent Earth Stations.

4. How can an Incumbent Earth Station operator determine if its Incumbent Earth Station is going to be part of Phase I?
SES has indicated in its Transition Plan (submitted to the FCC on June 19, 2020) which Incumbent Earth Stations accessing SES satellites will require Passband Filters in Phase I and Phase II. 

5. What are the benefits of being an Incumbent Earth Station?

  1. Cost reimbursement: The FCC allows for reasonable and actual costs to be reimbursed through the Relocation Reimbursement Clearinghouse for all Incumbent Earth Stations.
  2. Protection from 3.7 GHz Service interference: The FCC has defined technical rules for 3.7 GHz Service licensees that include maximum power flux density (PFD) levels at Incumbent Earth Station locations. The combination of passband filters and maximum PFD levels reduce the risk of harmful interference from 3.7 GHz Service emissions into Incumbent Earth Stations. The requirements are set out in Sections 27.50, 27.53, and 27.55
  3. SES will include a listing of Incumbent Earth Stations accessing SES satellites in the SES Transition Plan, which may be adjusted based on an official list from the FCC.

6. What does it mean that an Incumbent Earth Station can take a lump sum as determined by the FCC?
The Order provides for Incumbent Earth Stations  to elect a lump sum payment equal to the estimated reasonable transition costs of earth station migration and filtering, as determined by the Wireless Telecommunications Bureau, in lieu of actual relocation costs.  If an Incumbent Earth Station operator elects the lump sum payment, it is responsible for coordinating with the relevant space station operator as necessary and performing all relocation actions on its own, including switching to alternative transmission mechanisms such as fiber, and it will not receive further reimbursement for any costs exceeding the lump sum payment.  It must also inform the appropriate space station operator(s) and the Relocation Coordinator that earth station migration and filtering will not be necessary for the relevant earth station site and must coordinate with operators to avoid any disruption of video and radio programming.

7. What is the amount of the lump sum? 

On July 30, 2020 The Wireless Telecommunications Bureau (WTB) released the final C-Band Cost Category and Lump Sum Public Notice. With this Public Notice, Wireless Telecommunications Bureau (WTB) released the 3.7 GHz Transition Final Cost Category and the optional lump sum payment accounts for eligible incumbent FSS earth station operators and announced the process and deadline for the lump sum elections. See link below for all instructions and information. The Deadline to accept the lump sum payment is August 31, 2020.

8. What happens if an Incumbent Earth Station elects a lump sum?
If an Incumbent Earth Station chooses a lump sum, it must choose the same option for all earth stations that it has registered.  For example, if a major cable operator chooses a lump sum for its main earth station, it must also choose a lump sum for all its registered earth stations, regardless of size, location, etc.

In addition, the Responsible Satellite Operator(s) responsible for service to that site is no longer responsible for transitioning that Incumbent Earth Station site by the accelerated clearing deadlines.  Any Incumbent Earth Station that is subject to the lump sum election can be deemed as transitioned by the Responsible Satellite Operator.

9. What happens if an Incumbent Earth Station does not elect a lump sum?
If an Incumbent Earth Station does not elect the lump sum option with the FCC, then one or more of the Space Station Operators must provide and install needed equipment at the earth station to ensure a smooth transition for that site to receive only in the 3820-4200 MHz band for those earth stations included in Phase I and in the 4000-4200 MHz band for all stations at the end of Phase II.

SES itself is responsible for providing and installing needed equipment at any Incumbent Earth Station that has an antenna pointed to one or more SES satellites and did NOT choose the lump sum payment. Until an Incumbent Earth Station has the ability to choose a lump sum reimbursement, the Incumbent Earth Station operator will be included in the SES Transition Plan.

10. What is SES’s transition/implementation process?
Below is an overview of the general implementation process. Please review the full transition plan for more details.

  • SES receives a list of the Incumbent Earth Stations either from a customer or from the FCC’s IBFS database, which is currently being finalized by the FCC and will likely become official in Q3 2020.
  • Incumbent Earth Stations who elect a lump sum payment will be removed from the list.
  • Every Incumbent Earth Station that does not elect a lump sum payment will be contacted by an outreach vendor (currently Superior Satellite Engineers and ATCi (a subsidiary of Evertz Microsystems, Ltd) to confirm general earth station information. To ensure a smooth and efficient transition with minimal service disruptions, SES asks that all Incumbent Earth Station operators respond in a timely manner.
  • The outreach will also determine equipment required for the transition (antenna equipment, filters, etc.) depending on the needs of the site in accordance with SES’s customer transitions.  This will include a determination if the site requires a new antenna to access a satellite that the site does not currently access. It will also include a determination of the number of antennas at the site accessing SES satellites, which will define the number of Passband Filters that must be installed to minimize interference from 3.7 GHz Service emissions.
  • All filters will be purchased by SES, held in a warehouse, and shipped out to the Incumbent Earth Station or to the SES-hired installer.
  • The SES-hired installation teams will call the Incumbent Earth Station operator to schedule a time window to install equipment, based on SES’s transition plan. For example, all MVPDs will most likely be scheduled within the last 6 months of the Phase I and Phase II clearing timelines since most MVPDs will require access to several satellites and all transitions on those satellites will need to be completed before any filters are installed. On the other hand, some Incumbent Earth Stations such as those that only need access to one satellite may be able to accommodate the installation of filters at any time.

11. Will all Incumbent Earth Stations receive technology upgrades to assist them with receiving signals that have been compressed on the satellite?
No. In its Transition Plan filed with the FCC, SES noted that it only has one customer that will implement compression. Affiliates of that one customer will be contacted directly regarding the equipment needed for the Technical Upgrade. If you are not contacted by SES regarding a Technology Upgrade, then you are not affected by this requirement on SES satellite. 

12. How are Earth Station on Vessels (ESVs) affected by the Order?
As set forth in Appendix A – § 2.106 Table of Frequency Allocations of the Order, the allowable reception in the 3700-4200 MHz is as follows:

  1. When in port and docked within CONUS, an ESV can operate in the 4000-4200 MHz band and have protected status via frequency coordination. 
  2. When in port and not coordinated or when at sail, ESVs are authorized to operate in the 3700-4200 MHz band but without protected status.  Note that if a passband filter is in use on the ESV, it will preclude the reception of services below the passband cutoff frequency.

Note that the use of a passband filter may reduce the effect of interference from 3.7 GHz Services on received satellite signals in the 4000-4200 MHz band.

13. Can I use any filter advertised as a “5G filter”?
These are not recommended for antennas pointed to SES satellites. SES plans to provide Passband Filters – built and tested to SES specifications and meeting FCC requirements as set forth in the Order – to all antennas at an Incumbent Earth Station location accessing SES satellites that have not opted for the lump sum payment. Frequencies used outside of the CONUS for 5G deployments in the C-band may be different than those used in CONUS; therefore, the filter specifications may not be adequate for CONUS.
