HISTORY AND BRIEF TECHNOLOGICAL OVERVIEW
This technology is only a couple of years old. Brought in by a company called "Unwired Planet", a combination of the leading telecommunications companies.
HOW THE SYSTEM WORKS:
Make a request in WML (Wireless Markup Language), a language derived from HTML especially for wireless network characteristics.
This request is passed to a WAP Gateway that then retrieves the information from an Internet server either in standard HTML format or preferably directly prepared for wireless terminals using WML.
The requested information is then sent from the WAP Gateway to the WAP client, using whatever mobile network bearer service is available and most appropriate.

FREQUENTLY ASKED QUESTIONS
Which content is possible to access with WAP?
Almost anything available on the net; weather, news, stock market information, product updates, software downloads and so on. There is also a broad spectrum of other possible applications: e-mail, information search and retrieval, e-Commerce, calendar and office applications, maps and position-based services, voice messaging and communication, call control, Intranet/Internet access, among others.
What type of devices will use WAP?
Handheld digital wireless devices such as mobile phones, pagers, two-way radios, smart phones and communicators from low-end to high-end.
Is WAP suitable for multimedia mobile services?
A current area of interest within WAP Forum is evolution to support multimedia mobile services. WAP is an open protocol that allows the transport of many forms of multimedia content. However, some multimedia services, especially those based on streaming media, require further enhancements to WAP.
What are the properties of WAP?
WAP can only support DOS-like 2D graphics which are shown on the screen of the WAP devices. The current downloading speed of WAP is between 9.6kbps to 14.4kbps, depending on the telecommunication network it is riding on.
What is a WAP gateway?
The WAP gateway/proxy connects the wireless world with Internet/Intranet, providing a path from the WAP-enabled handsets in the wireless world to applications on the Internet/Intranet. In addition to being a bridge between the Internet world and the mobile world, the WAP gateway/proxy offers service logic such as:
a) End-user authentication
b) Encoding of WML pages
c) WML script compiling
Can WAP connect me to any site that I want to?
As long as the site has been "wapified", that is, the site has been written in WML (wireless markup language) that is accessible by WAP devices.
Is surfing the Internet on a WAP device similar to surfing on a PC?
Pretty similar. The main difference is that WAP does not support fanciful graphics as WAP is written in WML . WAP supports real time text information and simple DOS-like graphics.
What is the difference between WAP and SMS?
With ordinary SMS one can send text messages to mobile phones, e.g. receiving today's news or sports results. But SMS can only give the mobile phone user a limited degree of interaction. One can compare SMS with email: one can send and receive messages but it is not really possible to take any action or easily navigate to other information. WAP could be compared with an Internet browser: it supports hyperlinks for easy navigation and forms that are easy to fill in with selected data and receive a response. In conclusion, the difference between WAP and SMS could be compared to the difference between an Internet browser and Email.
What is the difference between WAP and SIM?
One can create custom-built applications with SIM Application Toolkit (ATK) that runs on the SIM card in the mobile phone. A SIM card is the Smart card that identifies the user and where the user's phonebook is located. With SIM ATK one can set up new menus, show text in the display, get access to the phonebook and send / receive SMS messages. The difference between WAP and SIM ATK is that SIM ATK applications are located in the phone on the SIM card, and to update an application one has to exchange the SIM cards of all the users. WAP applications on the other hand are fetched from a web-server and can be updated at one central location. Smart cards will have a role to play in the fuure in WAP security and user/operator personalization.
DISADVANTAGES OF WAP
Expensive.
Did not have a packet-based service for long time.
Limited size of RAM and ROM.
Limited power supply.
Low bandwidth.
Difficult to keep the phones up-to-date with new WAP serv
