Introduction

The wireless telecommunication and the Internet are rapidly growing industries that are gaining
more and more customers every day. The WAP intention is to combine these two markets and
answer the new demands in this field. These reasons and more driven some of the largest
vendors to unite and create the WAP Forum, the standardizing organization of the WAP.
WAP specifies an application framework and network protocols for wireless devices such as
mobile phones, pagers and personal digital assistants. WAP specifications extend existing mobile
networking technologies such as wireless networking standards and extend some Internet
technologies such as XML, scripting and content formats.
Wireless hand-held devices preset a more constrained computing environment and platforms,
compared to desktop computers which most of the Internet technology was developed for. The
hand-held devices tend to have less powerful CPU, less memory, very restricted power
consumption and problematic MMI (smaller and variant displays, phone keypads, etc.).
Furthermore the wireless networks present greater problems as communication infrastructures
they have less bandwidth, more latency and less connection stability and unpredictable
availability. WAP intends to overcome these difficulties by being interoperable, have scalable
quality of service, efficient in the mobile network resources, reliable and secure.
Technical Concept Introduction

The WAP programming model is similar to the WWW programming model. This provides
several benefits to the application developer community, including a familiar programming
model, a proven architecture, and the ability to leverage existing tools (e.g., Web servers, XML
tools, etc.). Optimizations and extensions have been made in order to match the characteristics
of the wireless environment. Wherever possible, existing standards have been adopted or have
been used as the starting point for the WAP technology.
