This presentation introduces the Wireless Application Protocol (WAP). WAP was created by mobile companies to provide an open standard for wireless information and services. It uses WML as its markup language. The presentation describes WAP's architecture including its protocol stack and WAP gateway. It also discusses how WAP addresses limitations of wireless devices and networks, such as small displays and low bandwidth. Examples of WAP services mentioned include banking, shopping, news and email. In conclusion, the presenter notes that WAP will become more efficient with the rollout of 3G networks like UMTS.

- 2. TechnicalSeminarPresentation2004 Presented by- V.SWARNA IT20098156 Wireless Application Protocol INTRODUCTION WAP has been created by companies like NOKIA, ERICSSON, and MOTOROLA. Main Objectives are: •Open to all • Application scale across transport options(GSM etc..) • Application scale across device types. • Extensible overtime to new networks and transports(eg. 3G systems)
- 3. TechnicalSeminarPresentation2004 Presented by- V.SWARNA IT20098156 Wireless Application Protocol WAP stands for Wireless Application Protocol. WAP is the global standard for presentation and delivery of wireless information and telephony services. WAP uses mark-up language WML WAP allows carriers to strengthen services with information we want and need while we are on the move. What is WAP?

TechnicalSeminarPresentation2004 Presented by- V.SWARNA IT20098156 Wireless Application Protocol WAP SOLUTION FOR THE WIRELESS DEVICE Small Display: The WML structures documents are in cards and decks. Limited input facilities: WML addresses the issue as well. Limited memory and CPU: WAP address this restriction by defining a lightweight adapted to its purpose. Limited battery power: This issue is solved by minimizing the bandwidth needed and thus keeping the bearer utilization as low as possible.

High Latency: minimizing the roundtrips between the wireless and the wireless network. Less connection stability /unpredictable Bearer availability: since no connection is set up the effects of lost bearer and times of inactivity are minimized by the transaction layer WTP.

TechnicalSeminarPresentation2004 Presented by- V.SWARNA IT20098156 Wireless Application Protocol CONCLUSION • WAP can be considered as a development running parallel to the web. • WAP will reach a large population and make the subscribers more comfortable • WAP is at too slow because it uses GSM network. • WAP will become more efficient with the advent UMTS.
