wireless application protocal(wap)

By, Raghavendra.K,

Introduction:

Barely a decade ago, when Internet was in its

infancy, the mere thought that a person could

access a global database of information right from

his/hers room was thought to be science fiction.

Could a person chat with his wife, bid at the stock

exchange, keep in touch with the latest in sports

and business, catch up on some research, all

while commuting to and from his office?

Definition of WAP WAP aims to integrate Internet, wireless data, and

telephony.

WAP works with all types of wireless networks

including GSM, TDMA, CDMA, and the upcoming 3G

networks.

WAP addresses issues

low bandwidth

devices with small displays

limited processing power and memory

batteries

WAP follows the client-server Web model of interaction

WAP gateways (proxies) are needed to sit between the

client (WAP device) and the Web servers.

Motivation• Limitations on Mobile Terminals:

• Less powerful CPUs and memory• Restricted power consumption • Smaller displays

• Limitations on Mobile Networks:• Less bandwidth• More latency• Less connection stability and less predictable availability

How we over come these, using WAP:

We use, Binary transmission :- For long latency and low bandwidth

WAP sessions cope with intermittent coverage :- For Less connection stability and

less predictable availability

Wireless Markup Language (WML) :-For smaller displays

The need for WAP

With out WAPWe need Higher

bandwidth HTML and TCP/IP

significant amount of bandwidth

Lost of signals.TCP/IP is not

inherently secure.TCP/IP not

supported by all wireless network

With WAPTailored for small

devices and low bandwidth.

The application developer must always be aware of the user and take into account the usability issues if the application is to be a success.
