THEMES

• Satellite Communications is the only way to
  provide broadband digital services reliably to
  rural/remote/transient populations
• Satellite Communications is a global/regional
  business providing transnational solutions
• Satellite Communications is perceived as a costly
  and risky proposition with a conservative
  business model not appropriate for consumer access

5
TRUTH vs MYTHS

• Satellites are generally as reliable as
  terrestrial lines
• Satellites offer continental, instant coverage
• Cost effectiveness relative to terrestrial
  services varies
• Satellites offer a seamless technology solution

Broadcast Solutions

• Satellites conventional role
• Terrestrial Transmission Problem
• Satellite TV Solution
• Terrestrial Trunking
• DTH Services using DVB-S

Satellites are higher in the sky than TV
antennas, so they have a much larger "line of
sight" range

Satellite Internet

• Increasing Role of Internet in everyday life
• Connectivity problems in Africa
• Advantages of Internet via Satellite
• Connecting to Internet by VSAT
• Internet Applications

Concluding Remarks

• The role of satellites is changing from the
  traditional telephony and TV broadcast services
  to user oriented data services
• Satellite data services like VSAT, will continue
  to compete with the terrestrial options such as
  Telephone line and Fiber links
• With the varied geographical terrain and widely
  dispersed population in Africa satellite based
  solutions will continue to be far more
  cost-effective
• Satellite will help bridge the digital divide
  between Africa and the Developed world
