The Wireless Application Protocol Forum is an industry group dedicated to the goal of enabling sophisticated telephony and information services on handheld wireless devices. These devices include mobile telephones, pagers, personal digital assistants (PDAs) and other wireless terminals. Recognizing the value and utility of the World Wide Web architecture, the WAP forum has chosen to align its technology closely with the Internet and the Web. The WAP specification extends and leverages existing technologies, such as IP, HTTP, XML, S ....etc

The SAT (SIM Application Toolkit) provides a flexible interface through which developers can build services and MMI (Man Machine Interface) in order to enhance the functionality of the mobile. This module is not designed for service developers, but network engineers who require a grounding in the concepts of the SAT and how it may impact on network architecture and performance. It explores the basic SAT interface along with the architecture required in order to deliver effective SAT based services to the handset. ....etc

Abstract
Mobile computing-CDPD technology
A technology that allows transmission of data, via a computer, without having to be connected to a fixed physical link. Mobile voice communication is widely established throughout the world and has had very rapid increase in the number of subscribers to the various cellular networks over the last few years. An extension of this technology is the ability to send and receive data across these cellular networks. This ....etc

CDPD is a secure, proven, and reliable protocol that has been used for several years by law enforcement, public safety, and mobile professionals to securely access critical, private information. CDPD has several features to enhance the security of the mobile end user's data and these are discussed below.

OPERATION OF CDPD

A brief overview of the operation of the CDPD network is as follows:
A wireless modem (or Mobile End System-M-ES) communicates by radio with the Mobile Data Base Station (MDBS). The MDBS transfers this data by landline ....etc

The Wireless Application Protocol (WAP) is a result of the WAP Forum s effort to promote industry-wide specifications for technology useful in developing applications and services that operates over wireless communication networks. WAP specifies an application framework and network protocols for wireless devices such as mobile telephones, pagers, and personal digital assistants. (PDAs). The specifications extend and leverage mobile networking technologies (such as digital data networking standards) and Internet technologies (such as XML, URLs, ....etc

OpenGL is a widely-accepted application programming interface (API) for interactive 3D graphics rendering and 2D imaging. It provides device-independent support for common low-level 3D graphics drawing operations such as polygon specification, basic lighting control, transformation specification, and framebuffer operations like blending and depth-buffering.

It also provides mechanisms for sending and retrieving 2D images to and from the framebuffer, and integrates 3D graphics with 2D imaging through texture mapping. While other low-level gra ....etc
