The document discusses the impact of smart devices on mobile networks based on testing done in Nokia Siemens Networks' Smart Labs. Key findings include: 1) Smartphones and tablets now generate the majority of mobile data traffic compared to older mobile devices. Data usage per device is increasing rapidly. 2) The proliferation of different cell sizes and wireless technologies has created a heterogeneous mobile network environment that is difficult to manage with traditional methods. 3) Initial Smart Lab tests found that advertising delivered with Angry Birds gameplay more than tripled signaling traffic on Android phones compared to the game alone. 4) VoIP calling on smartphones was found to consume more power and network resources than traditional cellular voice calls, while often

4. Ecosystem development with Smart Labs
• 5 Smart Labs globally:
- 2x Europe (Spain, France)
- Dallas, US,
- Seoul, Korea
- Taiwan
• Open for all developers and
operators
• Improve user experience and
network performance
• Results benefit all players
