  1. TECHNICAL SEMINAR ON WIRELESS APPLICATION PROTOCOL Presented By MD.ASLAM Adm. No. 05-125,ETC/2008

  2. WIRELESS APPLICATION PROTOCOL WAP or Wireless application protocol is a protocol or process which provides a method to communicate across wireless networks quickly, securely and efficiently. It is a standardized way that a mobile phone talks to server installed in the mobile phone network. It is an important development in the wireless industry because of its attempt to develop an open standard for wireless protocols, independent of vendor and airlinks. It is an emerging industry standard whose goal is to provide wireless internet link services and information to handheed devices. The goal of WAP is to extend the web to handheld devices by addressing and solving those difficulties.

  3. FEATURE PROVIDED ØModel closely interwined with that of tire Internet. ØHDML (Handheld Device markup language) It is the language which provides a programmer with the tools to produce content for a handheld WAP device ØWML (wireless mark up language) It is the language which allows a programmer to simultaneously develop web-based applications. ØOptimization of Data transfer : ØOperating System Independent : ØWireless Telephony Application (WTA)

  5. WAP LAYERS (i) Application Layers : a) Wireless application environment (WAE) b)Wireless telephone application (WTA)   They are the main interfaces to the client devices and specify a markup language a scripting language and a telephony interface.  (ii) Session layer  a) Wireless session protocol (WSP) WSP layer provides a lightweight session layer to allow efficient exchange of data between applications . b) Wireless transport layer security (WTLS) it is an option security layer that provides the secure transport service required by many applications.

  6. (iii) Transport layer • a) Wireless transaction protocol (WTP) • This layer provides transaction support, adding reliability to datagram service provided by WDP. • b) Bearer service • They provide reliable transmission of data packets between the client and server over a wireless link. • WDP(WAP datagram protocol) • It is a transport layer that sends and receives messages via any available bearer network. • HTTP interface • This serves to retrieve WAP content from the Internet requested by the mobile device..

  7. HOW WAP FUNCTION ?  1. WAP Programming model 2. WEB Programming model BROWSER SCRIPT INTERPRETER CONTENT SERVER HTTP/ HTTPS REQUEST (text) HTML DOCUMENTS (text) • WEB PROGRAMMING MODEL • A user enters a URL (Uniform Resource Locator) into a browser. • The browser parses the field and sends an HTTP or HTTPS request to a web server using ordinary text characters. • The web server replies to the request with either the specific document indicated by the URL or a default document if none is specified.

  8. CONTENT SERVER MICRO BROWSER WML SCRIPT INTERPRETER PROXY SERVER WAP ENCODERS & DECODERS WAP REQUEST HTTP / HTTPS REQUEST WAP REPLY WML DOCUMENTS • WAP PROGRAMMING MODEL •   The user still requests a URL. • The request comes from a microbrowser and it is transmitted in tokenized binary format. • The binary stream is processed through a proxy server that contains WAP encoders and decoders. • The proxy server translated the WAP request into an HTTP or HTTPS request that is relayed to a content server. • The content server replies with a text document that is encoded by the proxy server and transmitted to the WAP user agent.

  9. ADVANTAGE OF WAP • Open standard, vendor independent. • Network-standard independent. • Transport mechanism – optimized for wireless data bearers. • Several new handheld mobile and multifunctioning web enabled devices are gradually introduced. • The web enabled phones with the help of WAP technology will shrink the pc to palm size. • Mobile handheld gadgets will enable us to send and receive voice data, E-mail, conduct e-commerce obtain the latest quotes from the stock exchange data package using high speed internet service. • DISADVANTAGES OF WAP •  It is very difficult to configure WAP phones for new WAP service. • WAP does not provide direct internet access • The WAP standard is incomplete.

  10. APPLICATIONS : • It is considered as a gateway to new world of mobile commerce. • It provides a standard which enables users to easily access web based interactive information services and application from the screen of their mobile. • Its wide application includes consumer and corporate solution like email, corporate data, news, sports, entertainment, television, commerce transaction and banking services.

  11. CONCLUSION WAP is an emerging technology that has great potential. WAP bridges the gap between the mobile world and the internet as well as corporate intranets and offers the ability to deliver an unlimited range of mobile value added services to subscribers independent of their network, bearer and terminal. It is a global standard and is not controlled by any single company.
