Prof. Giovanni Emanuele Corazza gecorazza@deis.unibo.it
Outline
Part I: Trends in information society Part II: Wireless systems evolution Part III: The sixth framework programme (FP6)
Industrial society Part I Information society trends
1. Standardization 2. Synchronization 3. Centralization 4. Specialization 5. Maximization of E = P/H
TLC: Radio – TV broadcasting
Post-industrial society
1. 2. 3. 4. 5. Individualization Space/time de-structuring Distribution Continuous and flexible education Work/education/entertainment
The centrality of the human being
Information society?
• Competence and know-how are not enough! • Knowledge transformation, innovation, generation
TLC:
Cellular telephony (1G+2G) Internet IMT-2000 (3G) Broadband wireless (4G)
Thinking
• Critical • Creative • Constructive
