1. 1 Brian AYRES CEO, GlobalNet Inc. bayres@globalnet.cm Development of Telecom Networks in Africa

2. 2Media Continuing our discussion of yesterday, there are 2 main media used by telecom networks in Africa that interest us:  Fiber optic cable  Satellite

3. 3 Geographical Availability Fiber optic (terrestrial) – in certain cities/countries. Fiber optic (undersea) – at coastal locations in West Africa. Satellite – everywhere. The two media are generally complementary.

4. 4 Bandwidth availabilty New Skies  Virtually none Intelsat  None to Africa on certain satellites SAT-3  Currently used 20 Gbps  Upgrading to 40 Gbps.  120 Gbps is the limit

5. 5Reliability Fiber  Excellent but subject to the response time of the PTT in time of outage. Satellite  Excellent but subject to outages of a few minutes for a few days during eclipses twice per year.  This morning’s comments on VSAT availability.

6. 6 Developments (1) Fiber Optic Cable, undersea  EASSy (NEPAD)  IWTGC Fiber Optic Cable, terrestrial  Rail, pipeline  CBG

7. 7

8. 8 EASSy project

9. 9IWTGC The submarine cable system will run from Portugal to Cameroon along the coast of West Africa and will link Nigeria, Benin, Liberia, Senegal, Cote d'lvoire and Ghana.

10. 10 Developments (2) Satellite  New  RASCOM (2006)  NSS-8 (2006)

11. 11 RASCOM – C & Ku band

12. 12 RASCOM – Ku band

13. 13 RASCOM – C band

14. 14 NSS-8 Transponders 36 x Ku-Band 56 x C-Band

15. 15 NSS-8 C band West Hemi

16. 16 NSS-8 Ku band spot beam

17. 17 NSS-8 European spot

18. 18 "TRUTH and technology will triumph over BS and bureaucracy." Rene Anselmo, founder of PanAmSat

19. 19 Dog Spot

20. 20Mergers  Intelsat and PanAmSat  Fleet of 53 satellites 28 from Intelsat, 25 from PanAmSat Good news – economy of scale Better prices§

21. 21 Fiber Optic vs Satellite Is there a choice?  Not necessarily.  Maybe only satellite available – go satellite.  Maybe fiber less expensive – go fiber.  They are complementary.

22. 22 Fiber Optic vs Satellite (2) Is a homogeneous network necessary?  It is not even possible at the moment, unless it is satellite.  Why should it be necessary?  Why not use the best of fiber and satellite?

23. 23 Fiber Optic vs Satellite (3) Pricing  Is satellite more expensive than fiber?  SAT-3 Fiber: $3.7 / kbps in Cameroon.  Fiber pricing in other countries?  Satellite pricing $2 to $6, depending on satellite, beam, etc.
