4th Generation Networks

• Generation 1 - Manual Plug Board
• Manual work
• Human Processor
• Personal Touch
• Analogue Connection
• Doesnt Scale
• Generation 2 - Mechanical Automated Switched
• Dialled Number addressing by Geography
• Analogue connection
• Scales world-wide
• Costly maintenance
• No processor initially
• Generation 3 - Digital Automated Switched
• Digitized implementation of analogue (TDM)
• Computer controlled enables services beyond
  connection
• Low maintenance but still Geographically
  constrained
• Separate Voice and Packet infrastructure

Networking and Telecom EnvironmentYear 2006

• Broadband everywhere
• Widespread SIP
• Personal communication migrated to wireless
• Death of distance
• Web applications
• Open protocols/open source

• Telecom spend? faster than GDP growth
• Depreciation cycles?
• Payback/profit criteria?

TECHNOLOGY
ECONOMY

• Focus on individual (identity, privacy) rather
  than network
• Fostering competition
• Tariff on basic and monopoly services only
• Regulation directed to different layers within
  the industry

Operator

• All about who owns the customer relationship
• 1000s of service providers for all services
• Reduction in importance of monopolies

3GPP R5 network architecture
3GPP R5

• 3GPP R5 IM Subsystem provides a SIP and H248
  framework for the applications and control
  environment of converged wireless networks
• Applications creation environment (OSA) permits
  extending applications to users independently of
  their means and point of access
