WAP is a standard for accessing the internet from mobile devices such as phones. It was created in 1998 by major phone companies to allow browsing on small screens. WAP uses protocols like WSP, WTP, and WTLS to securely transfer data. At the top level is WAE, which defines the user interface. Below this are layers like WSP for sessions and WDP for transport. WML is used to author pages for mobile screens. WAP allows functions like checking schedules, purchasing tickets, and getting weather/stock updates from internet-enabled mobile phones.

2. MEANING OF WAP:
 WAP (Wireless Application Protocol) is a specification
for a set of communication protocols to standardize the
way that wireless devices, such as cellular telephones and
radio transceivers, can be used for Internet access.
WAP is a universal standard for bringing Internet-based
content and advanced value-added services to wireless
device such as phones and Personal digital
assistants(PDAs).

3. HISTORY OF WAP
The WAP Forum was founded in 1998 by Ericsson,
Motorola, Nokia and Unwired Planet. It aimed primarily to
bring together the various wireless technologies in a
standardized protocol.
The basic AIM of WAP is to provide a web-like experience
on small portable devices - like mobile phones and PDAs.

6. Wireless Application Environment (WAE)
• The wireless application environment(WAE) provides a
general-purpose environment for applications to be used
on wireless devices.
• It is based on a combination of WWW and mobile
telephony technologies.
• It defines the user interface on the phone. It contains
WML(Wireless markup language) and WTA (Wireless
Telephony Application).

7. Wireless Session protocol(WSP)
• The WAP session protocol (WSP) layer provides a
lightweight session layer to allow efficient exchange of
data between WAE and the rest of the protocol stack.
• It creates a session between the WAP client & the WAP
Gateways.

8. Wireless Transaction Protocol(WTP)
• WTP is defined as light-weight transaction-oriented protocol
suitable for implementation in thin clients.
• Each transaction has unique identifiers, acknowledgements,
duplicates removal and retransmission.

9. Wireless Transport Layer Security(WTLS)
• WTLS is security protocol based on industry standard
transport layer security (TLS). It provides transport layer
security between a WAP client and the WAP Gateway/ Proxy.
• The goals of WTLS are data integrity, privacy, authentication,
Denial-of-service protection.
• WTLS can be used with both the connectionless and
connection mode and is always placed on top of WDP.

10. Wireless Datagram Protocol (WDP)
 WDP is the Transport layer that sends and receives
messages via any available bearer network.
• It is the most bottom layer and responsible for moving WAP
data from sender to receiver & back again.
• Provides a common interface to the upper layer protocols
and hence they function independent of the underlying
wireless network.

11. Wireless markup language(WML)
• WML is WAP’s counterpart to the hypertext markup
language (HTML) on WWW. It is the page describing
language used for authoring service and is designed to fit
small handheld devices.
• It has been designed for low-bandwidth wireless devices
with limited input and output capabilities
• WML supports text and images, user inputs, navigation
mechanism and variables.

12. EXAMPLES OF WAP USE
Checking train table information
 Ticket purchase
Checking weather conditions
 Looking up stock values
 Looking up sport results
Real-time traffic reporting

13. ADVANTAGES OF WAP
• WAP is open standard. It is totally vendor independent
and network security standard independent.
• WAP’s transport mechanism is optimized for wireless
data bearers.
• WAP application downloaded from the server enable
faster service creation and introduction than embedded
software.
• Simplicity of use.

14. DISADVANTAGES OF WAP
• Small display screens
• Limited availability
• Slow access
• Hacking
