At the beginning of the birth, WAP was touched as a revolutionary communication application technology, and the entire mobile computing world seems to be refurbished. However, WAP and various services using WAP protocols have not played the role of mobile devices, mobile networks, and the main limitations of mobile networks and devices are:
Display screen narrow device memory capacity limited CPU computing power can be used to have a bandwidth too small connection unreliable delay, but there is a change after the new version of WAP - WAP 2.0 changes. Here I simply describe the technology of WAP and its use of WML display content. In addition, I will also explain what technically improved and improved on the basis of the 1.x version of 1.0, and finally explains the reasons for continuing to use the current version of the current. WAP works When accessing the website through a browser on a desktop computer operating system, the client will request a request, and the server is responsible for transmitting the data to the client through the IP network in HTML format. The web browser converts these HTML data to users readable text and images. There is a bit different on your mobile device, WAP replaces the web browser in a so-called WAP browser, and the device can request data to the website. The main difference between access data through desktop PC browser and WAP 1.x browser is that the WAP browser must use the WAP gateway to communicate such a communication entity. This so-called WAP gateway is functionally equivalent to the intermediary between the mobile network and the Internet network. The WAP gateway is located between the WAP browser and the web server, which makes the necessary binary encoding for the content, and can also perform mutual conversion to the WML and HTML code. The reason for using WAP has been mentioned above with a considerable limitations of mobile communication, but the WAP is used to implement mobile web browsing or sufficient reasons:
