Network Systems and Technologies (NeST), Trivandrum. 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

Network Systems and Technologies (NeST), Trivandrum. 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.
