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
![Page 15: Wireless Application Protocol. . The Two Paradigms W – World W – Wide W -- Web W – World W – Wide W – Wireless W -- Web.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649e4f5503460f94b4715a/html5/thumbnails/15.jpg)

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
![Page 16: Wireless Application Protocol. . The Two Paradigms W – World W – Wide W -- Web W – World W – Wide W – Wireless W -- Web.](https://reader036.fdocuments.us/reader036/viewer/2022062518/56649e4f5503460f94b4715a/html5/thumbnails/16.jpg)
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.
