    1. 1. W@P by:M@k$ha Zala (106050316022)
    2. 2. What is WAP ? WAP is Refer as Wireless Application Protocol. WAP is an open International Standard for application layer network communications in a wireless communication environment. WAP allows us to access information over a wireless network. It’s a kind fusion of different technologies. It has more power to access and interact with wireless
    3. 3. Definition of W@P All application loaded onto any wireless system must follow a specific protocol in order to be used by any specific machine, the protocol which they follow is called WAP.
    4. 4. WAPA set of protocol which allow data exchange for mobilecellular systemsIt’s device independent.It is network independent.WAP is for handheld device such as mobile phones.WAP enables the creating of web application for mobiledevices. WAP uses the mark-up language WML(not HTML).WMLis defined as an XML 1.0 application.
    5. 5. Cont… WML stands for Wireless Markup Language. it a mark- up language inherited from HRML, but WML is based on XML, so it is much stricter than HTML. Differs from HTML • XML was specifically designed for wireless terminals with a target screen that is only a few lines loan and about an inch wide. • XML is case sensitive, and all tags and attributes should be in lowercase. • WML doesn’t assume that keyboard or a mouse is available for user input
    6. 6. Aim of WAP The Basic aim of WAP is to provide a web service like experience on small portable device – like mobile phones. To enable easy , fast delivery of relevant information and services to mobile users.
    7. 7. Architecture of WAP
    8. 8. WAP GATEWAY Intermediary element used to connect two different types of network. It receives request directly from the clients as if it actually were the origin server that clients want to receive the information form. The clients are usually unaware that they are speaking to the Gateway.
    9. 9. Working of WAP
    10. 10. Function of WAP WAP is an application communication protocol. WAP is used to access services and information. WAP is for handheld devices such as mobile phones. WAP is protocol designed for micro browsers. WAP enables the creating of web applications for mobile devices.
    11. 11. Usage. WAP enabled handsets to get instant, direct access to the latest pricing, latest news, competitive information any time, anywhere. Users can get sports results, News downloads. It can also be used to purchase products and services over the web. Using WAP users can keep track of their email right from their handset.
    12. 12. Advantage Easy, and fast access to Internet. WML and WML Script(new language, which is based on HTML). Large choice in mobile phones(most of them support WAP). Can be used to download abstract data types(videos etc.) supports most wireless networks (like: CDMA,GSM,PDC, PHS, TDMA etc.) Can be built on any operating system.
    13. 13. Disadvantage of WAP Small screens: for web phones, there’s an incredibly small viewing. Speed of access: all devices have slow access. Limited availability: wireless web access is irregular in many areas and entirely unavailable in other areas. Lack of user habit: it takes some patience and overcoming the learning curve to get the hang of it— connecting, putting in an address, typing. User just aren’t used to the idea and protocol yet.
    14. 14. Type of devices that use WAP• Handheld digital wireless devices such as mobile phones , pagers , two-way radios, smart phones and communication from low-end to high-end.• Multimedia messaging services(MMS) is a combination of WAP and SMS• WAP is the initiative to bring cable internet to wireless internet
    15. 15. Summary WAP provides a markup language and a transport protocol that open the possibilities of the wireless environment. WAP is an enabling technology through gateway infrastructure deployed in mobile operator’s network. WAP is independent of OS that means WAP can be implemented on any OS.
    16. 16. • The Wireless Application Protocol (WAP) is a result of continuous work for developing applications that operate over wireless networks.• We conclude that it is possible to guarantee a sufficient security level on the condition But users should always bear in mind that an absolute security is a pure impossibility
