So Far …
• Cell phones will be the dominant device for wireless applications, although they will inherit PDA-like functionality
• By combining WAP, IVR, location and proximity detection, the stage is set for a new generation of wireless applications that can truly change the way we perceive wireless

Exciting Possibilities
• Embedded Java will do away with performance and memory issues
• “WAPLETS” will allow you to dynamically download Java byte code and execute them on the cell phone
• Voice will be a predominant option for data entry, but key pads will still be used for secure data
Future …
• Leverage IVR (Interactive Voice response) technologies to reduce data entry woes.
• Location and proximity detection technologies…Global Positioning system
• Convergence of WAP and Bluetooth
• Evolution of Wireless networks towards 3 and 4G.
Conclusion …
• SMS and WAP continue to be the key technologies for wireless application development
• When you design for wireless, don’t take a “porting” approach towards your application. Instead, focus on how you can leverage the strength of the medium to design your next killer app.
