- 2. Tina Balke, University of Bayreuth / University of Bath WIRELESS MOBILE GRIDS: POTENTIAL STARS, CASH COWS, QUESTION MARKS OR DOGS AND HOW TO FIND OUT?
- 3. Financial Challenges for the Mobile Phone Sector Intensifiedcompetition due to market penetration of 132% (EU) ARPU: 15/month (Germany) Negative profit margin of -7% is expected by 2012 (for some companies, negative EBITDA expected) (EU)
- 4. Infrastructure Challenges for the Mobile Phone Sector Application demand for digital content is rising Infrastructure network capacity is limited Smartphone battery life cycle poses a big problem, and is considered especially important by customers Smartphone compute and ad-hoc network facilities are under-utilized
- 5. Wireless Mobile Grids A Solution!?
- 6. The Public Good Problem in Wireless Mobile Grids
- 7. Life Cycle Costs Source: BCG
- 8. Essential Question: How to can we find out if wireless mobile grids can actually work and are worth investing in?
- 9. Norm. Models for Evidence- Based Process Analysis Technical Foundations (Energy & Transmission Normative Model Model) Normative Multi- Agent-System Simulation Financial Model User Model
