SATELLITE INDUSTRY SAFEGUARDS C-BAND
FREQUENCY SPECTRUM USE AT WRC-07

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.

(…/2)
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.
