Satellite Industry Safeguards C-Band Frequency Spectrum Use At WRC-07

20 octobre 2021 Pierre Perrin-Monlouis

Geneva, November 16th, 2007 – The global satellite industry emerged today from four weeks of successful negotiations to protect the users of its C-band spectrum from terrestrial interference. With its unequivocal “no change” campaign, the satellite industry at WRC-07 has ensured its uninterrupted, interference-free use of C-band for the future. The 2007 World Radiocommunication Conference (WRC-07) of the UN’s International Telecommunication Union (ITU), is the place where 191 Member States assemble every four years to work out the rules by which countries get to use the precious radio frequency spectrum.

“This outcome represents a strong endorsement by a large number of administrations of the critical nature and value of C-band satellite services as they exist today,” said Rob Bednarek, CEO of SES NEW SKIES, an SES Company. “The certainty and stability provided by today’s outcome allows us to continue our further development of new markets and services, including mobile broadband, by an industry well acquainted with customers real needs.”

Andrew Sukawaty, Chairman and CEO of Inmarsat, stated: “We would like to thank all WRC 2007 delegates for recognizing the importance of the C-band for the satellite industry. Their decision to protect the C-band will enable us to continue offering essential communications to mobile users where terrestrial networks cannot reach, including aeronautical and maritime safety services””.

In addition to ensuring their uninterrupted use of the C-band, WRC-07 also gave satellite operators assurances that any future IMT (International Mobile Telecommunications) networks will provide them with full protection from interference. The endorsement of the satellite industry’s use of this highly valuable spectrum in the band 3.4 – 4.2 GHz will ensure that operators will also have adequate bandwidth to roll out future service – especially in those regions where they are most in demand. These include the developing world, large industrialized countries, and remote regions.

“The results from the conference were very positive for the satellite industry,” Phil Spector, General Counsel of Intelsat, commented. “The satellite industry and our customers worked together in an unprecedented manner to raise the awareness of regulators to how critical satellites are to the global telecommunications infrastructure,” Spector continued.

The WRC has decided against the global identification for IMT, including Wimax, in any part of the satellite C band (3.4-4.2 GHz). In effect, the ITU table of allocations remains unchanged and the limited number of countries in favour of change are identified in an opt-in footnote. With this approach, the world’s regulators participating in the WRC have clearly signaled that these bands are not globally harmonised for IMT. The WRC further restricted IMT, including Wimax, by imposing stringent requirements for the protection of existing and future satellite services in the band, including transborder protection.

Specifically, in Region 2 (the Americas and the Caribbean), there is no identification for IMT, just an upgrade, through a footnote, in 14 countries of the mobile service allocation in 3.4-3.5 GHz. In Region 3, only a very few (8) countries inserted their name to the footnote identifying IMT. Only in Region 1 was there broader support from countries to be included in the footnote identifying IMT for national use.

This outcome therefore shows overwhelming recognition of the need for continued interference-free operation of C-band satellite services that are essential for the provision of national over-the-air and cable television services, emergency and disaster recovery communications, Internet services, and mobile and wireline telephony trunking services.

The WRC-07 saw a well-organized lobbying campaign that included support from governments, international organizations, non-profits, and technology companies. Also on offer was terrestrial spectrum below 1 GHz that results from the transition from analogue to digital television, and here the mobile network operators were awarded the promise to use much of that spectrum in years to come.
