My key note speech at Droidcon 2012 promoting DT's leadership in the Smartphone Challenge initiative. Smartphones have catapulted the distribution of mobile apps to new highs with increased usage of mobile networks. The Smartphone challenge project goal is to optimise the interaction between devices & networks DT understand the threat from network intensive, badly designed applications and developed developer guidelines. DT alone cannot influence the market and we decided to leverage the support of GSMA, industry affiliates and developers themselves.

4 How Smartphone apps impact mobile networks Smartphone users Network Operator apps Service providers Apps ‘chattiness’ overloads Operators signalling network
5 How Smartphone apps impact mobile users source: T-Mobile US analysis for G1, defined user activity (power user) and two different Instant Messaging applications as on top activity in comparison Apps ‘chattiness’ consumes battery life Traffic Pattern 33% 73% 100% G1 with heartbeat: every 28 minutes IM App A reload: every 4 minutes IM App B reload: every 1 minutes Battery LifetimeApps activity (chat)
6 Smartphone Challenge - eco system approach Apps Networks Terminals AppsOS TerminalsNetworks OS Collaborate with OS suppliers to optimize efficiency Drive mitigating features through 3GPP Ensure integration into terminal specification Optimize network configuration Drive resource friendly features within network releases Execute granular load monitoring Analyze Apps and address critical behavior Drive harmonized developer guidelines through GSMA
7 Mobile Network ‘Know-How’ for 3rd party developers Objective:  The “developer guidelines” document aims to create awareness amongst new/novice developers while encouraging better development habits.  Provides a set of key principles (some independent of the underlying platform) covering:- Asynchrony Connection Loss and Error Handling Caching Efficient Traffic Usage Compression Background/Foreground Modes Security Scope :  Targeted at Android, Windows Mobile & iOS
8 Developer Guidelines – what areas are addressed? Connection Loss + Error Handling Asynchrony Latency Non-Modal User Interface Connectivity User Experience Compression Fast Dormancy HTTP Cache Data Formats Network Efficiency Security Media Transcoding Local Cache Application Scaling Optimizing Network Requests User experience Mobile connection Device battery
9 Asynchrony Connection Loss + Error Handling Latency Non-Modal User Interface Connectivity User Experience Asynchrony Connection Loss + Error Handling Latency Non-Modal User Interface Connectivity User Experience Connectivity User Experience Topic : Asynchrony 9  Mobile networks are relatively slow Synchronous requests Asynchronous requests (ideal) Asynchronous requests (real mobile network) Image 1 Image 2 Image 3 (no response)
1010  Network activities should be visible to the end user Connectivity User Experience Topic : Non Modal User Interface  User interface should not be blocking Non Modal User Interface Connection Loss + Error Handling Aynchrony Latency Connectivity User Experience Non Modal User Interface Connection Loss + Error Handling Aynchrony Latency Connectivity User Experience
11 Fast Dormancy HTTP Cache Compression Data Formats Security Network Efficiency Fast Dormancy HTTP Cache Compression Data Formats Security Network Efficiency 11  Awareness of how networks save battery & signalling Power Datatransfer Before Network efficiency Topic : Fast dormancy After Power Time Datatransfer Data transfer =90kb Power used = x Time = y Data transfer =90kb Power used = x/3 Time = y/3 } } 30Kb 30Kb 90Kb 30Kb
