Requirements1. Understanding of Digital Divide

Digital Divide: Separation into two classes of communities:

■ Communities, households with the possibility to get Broadband Access■ Communities, households without possibility to get Broadband Access

Strong contradiction to initial target of an equally interconnected information society!

Rough quantity assumptions:

■ In developed countries about 10%-20% of the households are affected by the Digital Divide■ In the acceeding countries EUCC-10 the percentage of household affected by

the Digital Divide is even higher!



Requirements1. Understanding of Digital Divide

They understood - do we?



Requirements2. Political Situation, Public Programs: EU, ESA, F, D

EU:

ESA: Space-based solutions for digital equality The European Space Agency and the European Commission have decided to give jointconsideration to the use of space-based technologies to help bridge 'the digital divide'. An initial action plan has been put in place to define society's needs and point to potentialspace-based answers.

Initial Step: ITT AO/1-4579/03/NL/US: Digital Divide: The Satellite Offer




France:On January, 22nd, 2004, the french senate (!) organized a colloquium together with ESA:Collectivités territoriales et désenclavement numérique: la solution satellite?

Major results:

■ The french local and national authorities are aware of the consequences to be affectedby the Digital Divide

■ Several field trials are in place, most of them based on Satcom■ Satcom, as is, is too expensive■ Position of representant of ESOA = Organisation of Satellite Operators: Satcom has

deficiancies, but is better than nothing !?■ The industry is prepared to increase the efficiency of satcom■ French Minister of Technology provided a positive outlook for Satcom and announced a

national 200 M€ program, thereof 100 M€ national money and 100 M€ EU money!




Germany:

■ Implemetation of Arbeitsgruppe Telekom: German satcom industry, consultingrole of DLR

■ German industry positioned itself to play a leading role in the deployment of asatcom network to bridge the Digital Divide.

■ German consortium submitted proposal to ESA ITT Digital Divide: The Satellite Offer..:OHB, ND SatCom, Telesat, SatSpeed, IABG, VCS, TESAT.

■ DLR Workshop today: Creation of awareness:- General Importance for Satcom business- Creation of awareness at government: BMBF, BMWA- Discussion and hopefully definition of joint industrial/political strategy

Terminal cost/price not key parameter: Terminal cost/price is mostly driven by quantities!Quantities will be regulated by the market, if a suitable network exists, which allows theoperation with terminals accepted by the market. Example: GSM!

To support the procurement of terminals by the EUwill not create a competitive satcom network!

4. Future Position of Satellite Communication Networks: Chances & Risks

Prospects: Bridging the Digital Divide will be one of the most important issues on the political agenda, worldwide. The bridging will mostly be realised within the next 5 years, driven by a substantial public support.

Chances for Satcom: Satcom is the ideal means to bridge the Divide fast and complete. To realize that, Satcom has to prove the capability to provide a competitive unicast access network and competitive end user equipment. This is technically possible, but must be commercially supported. At our competitors such developments are also supported by military or funded commercial projects. Digital Divide opens a market opportunity for Satcom, which is in terms of bandwidth requirements by far bigger than the Broadcast business!

Risks for Satcom: Wherever the gap of the Digital Divide is closed by terrestrial networks and no competitive satcom network can be offered, the market for any type ofsatcom networks is jeopardized. Terrestrial Broadband networks are even a competition for satcom Broadcast networks!



Requirements5. Position of Satellite Operators

■ Satellite operators did significant investments in bidirectional systems duringthe „internet bubble“ period.

■ All systems are based on Broadcast networks, in some cases with Ka-Band extension for return traffic.

■ The role of the satellite operators is still unclear: Capacity provider, network operatoror even service provider.

■ The Satcom Broadband access business did not materialize.Reason from SatOp point of view: Terminals are too expensive.Real reason: Neither the Satcom network nor the sales/marketing structures nor the strategy of most of the satellite operators are prepared for a powerful entry into theBroadband market.

■ The more and more shorttermed and investor driven business policy forbids investments into a new network technology with mid termed business prospects.



Requirements5. Position of Satellite Operators

■ Satellite operators are aware of the long term risk caused by the reduction of theanalogue traffic

■ Mainly based on the past experiences satellite operators are not willing and not able to take the complete risk of an investment into a new network.

Are the established Satellite Operators positioned for the deployment of a Satcom Network bridging the

Digital Divide?



Requirements6. Ways to use the chances for Satcom

DDSO offer of German consortium

■ Spotbeam Structure: About 40 Spots over Europe■ Spotbeams with high EIRP and G/T: Small terminals■ Risk reduction: Transparent IP Booster■ Risk reduction: Scalable adaption to B/W

Requirements7. Conclusion

- Bridging the Digital Divide will define the satcom technology and businessof the next decade.

- Strategy and position of the established satellite operators is still unclear

- The German Satcom industry is prepared and positioned to play a leadingrole in the development and deployment of competitive Satcom broadbandnetworks.

- The DLR recognizes and supports the position of the German Satcom industry

- The political support as well through the BMBF as through the BMWA isnot developed yet and everything should be done to shift the politicalposition on a level, which fits to the commercial and technical importance of a bridge over the Digital Divide.
