• 2000 : Internet using Gen 1 satellites designed for TV broadcasting

• 1 Gbps capacity in Ku band – Gbps = 200 M$

• “dial up-like” (56 kbps for HH/SME & up to 2 Mbps for LMC)

• 2005 : Satellites Gen 2 designed for Internet connectivity

• 10 Gbps capacity using multi beam Ku/Ka wideband satellites

• DSL-like service (a few Mbps for HH/SME – for tens of euros)

• 2010 : Satellites Gen 3 designed for Internet connectivity

• 100 Gbps capacity using multi beam Ka HTS satellites

• ADSL2-like service (20 Mbps for HH/SME for tens of €)

• 2015 : Satellites Gen 4 optimized for various trends of Internet

connectivity : fixed and mobile, on the ground, at sea, in the air.

• 350 Gbps capacity in Ka band & Gbps = 1 M$

• Fiber-like service (50-100 Mbps for tens of euros)

• 2020+ : Satellites Gen 5 optimized for various trends of Internet

connectivity : fixed and mobile, on the ground, at sea, in the air.

• 1000 Gbps capacity in Ka band & Gbps < 1 M$

• Fiber-like service (50-100 Mbps for tens of euros)

A FAST EVOLUTION PULLED BY A GROWING

INCREASED/DIVERSIFYING GLOBAL DEMAND

A new generation of Geostationary Internet Satellites :

• Bus :

New generation, optimized for all electric propulsion, with payloads ranging from 400

kg to 3 t, 7 kW to 25 kW, accommodation of more/larger reflectors

• Payload :

Hundreds of beams, wide band (up to 2.5 GHz) and high power Ka-band throughput

providing 350 Gbps - up to 1 Tbps of capacity around 2020, with introduction of

flexibility

Feeder link in Q-V band, with progressive introduction of active antennas

An enriched and diversifying space offering with constellations :

• For Broadband Internet : complementary to GEO offering

Oneweb/Leosat – tens/hundreds of LEO (2000 km) satellites (200-1000 kg) providing low

latency backhauling for connecting terrestrial base stations or large mobile platforms –

A complement to the huge capacities delivered by GEO satellites over countries and

regions

• For IOT/M2M : complementary to IOT/M2M terrestrial networks for Global coverage

End to end coverage, both terrestrial and maritime – extension to polar areas

A FAST EVOLUTION ALLOWED BY AN

INCREDIBLE WAVE OF INNOVATION

Internet satellites

• An accelerator for the provision of communication services and the deployment of

terrestrial network (backhaul, trunking, ….)

• The economically sound geographical complement to terrestrial networks for TRULY global

internet connectivity and content distribution

• The necessary back up for sustained communications in times of crises

• The ideal companion of broadcasting satellites for triple play offerings

INTERNET SATELLITES : THE NATURAL COMPLEMENT TO FIBER AND

4G FOR BB everywhere

• Global coverage : everywhere, on the

ground, at sea, in the air

• Universal coverage : for everyone, be it

HH/SME, LC, Governmental

organizations, Fixed or Mobile

• A first solution before other arrive…. and

the only solution where none will ever

come

• Secured networks …. and networks

resilient to natural or human made

disasters

Growing demand for capacity provided by advanced Internet satellites

Satellite operators invest / will invest heavily in Internet satellites

Broadband satellite and universal coverage in a country like France

Area not covered

By fiber/cable/VDSL

by 2022

Rural or isolated areas in France

LTE : a stand alone solution for BB global coverage in the French rural

and/or mountainous districts?

• Simulation of LTE coverage in a French rural

district

• Results emphasize the natural complementarity

of LTE and Broadband Satellite for Ultra fast

broadband coverage of the last 10% POP

• Evaluation confirm a need for 500 k – 1 M BB

satellite connections over 2020-2030

Public initiatives in Europe for super high speed networks

• By co-funding R & D required for innovation, States help industry master innovativetechnologies and design the requested solutions : the European industry can design anycategory of Internet satellite.

• Orders of Internet satellites by commercial operators to respond to their strategy andmarket needs confirm the European industry know how and competitiveness

• Recent orders to the European industry include some covering the North Pacific, CentralAsia, Africa or the Americas… what about Europe?

• The need seems to exist : in France alone, much more than 1 million poorly served rural orisolated HH could get a BB (> 30 Mbps) connection by satellite for 30-40 euros a monthfrom satellites fully funded by private operators…

• But in theses rural or isolated areas targeted by satellite, terrestrial networks are deployedwith public support, which create a complex situation : one more area of the “broadbandfor all equation” where additional public guidance may be necessary?
