7.10 W@P
Introduction
The purpose of W@p (Wireless Application Protocol) is to enable easy and fast delivery of relevant information and
services to mobile users. However, mobile Internet does not mean navigating on the Internet with a wireless device
but rather to access to some services in a mobile context.
The W@P architecture was designed to enable standard Internet servers to provide services to wireless devices.
The W@P wireless protocol is based on Internet standards such as HTTP and TLS but has been optimized
according to the constraints of the wireless terminals: low
memory capacity, small screen size
and of the network: limited bandwidth.
The W@P architecture is made up of 4 technological parts which are necessary for accessing W@P services on a
mobile phone. These are:
W@P navigator or browser
Mobile operator network
W@P gateway / W@P server
Web server
* Subscription
The customer has to contact his Network Operator to inquire about his subscription and the options he can
subscribe to. Generally the customer just have to request his W@P access to his provider and he will not be
charged for that.
