Experiences using Satellite

• Capital costs and line rental charges

• Planning permission, advance booking

• Implications for scale-up

• Overcoming barriers to networking

• Breaking down barriers, traditions

• Security, reliability, satisfaction

• Perception - synchronous activity

Potential for Development

• Transferability - other regions, EU, world

• New technologies - ADSL, PowerLine

• Live interactive TV lectures

• Videoconferencing

• Data broadcast services

• VSAT 2-way data services

• Role of TERENA
