4.3 Network Operators Network operators want to offer more advanced and usable value-added services, and also more usable interfaces to current services like call forwarding in addition to entirely new ones. In future, we there will be more and more computing power and bandwidth but unless major advancements in battery technology occur, electrical power will be limited and more powerful processors of one generation will always consume more of the precious battery energy. The Solution WAP is designed to be a consistent, small footprint, and bandwidth solution for wireless applications. Only essential parts of existing protocols are taken. Everything is bandwidth optimised by minimising headers and using compressed binary format instead of plain text.
Information security is an integral part consistent with all protocols.
Technology WAP is not, despite of its name, a single protocol but a stack of protocols that implement different layers needed for communication, applications, crypting, etc. This chapter gives a brief introduction of the protocols. Figure 1 - The WAP Protocol Stack. WAE offers the software platform environment for the application software. WAE is built into the so-called micro browser program that works much like normal WWW browsers that interprets HTML and JavaScript.
