General Mobile App Issues

• Physical hardware differences– Display size– Input methods– Radio/network types

• Rapidly evolving OS versions– e.g. Android 1.0, 1.1, 1.5, 1.6, 2.0, 2.1  all in 18 months! 

• Customization and extensions– New features &applications – Device OEM and Carrier requirements

• Lack of native VoIP / IP Communications support

Conclusion

• Communications modes and services– IP Communications enables UC, Social 

Networking, collaboration 

– Carrier vs

OTT?  • Business model vs. customers requirements issue

• Mobility is about users NOT devices

• Need for standardization – Android: OESF for new applications
