WAP

WAP (Wireless Application Protocol) is a specification for a set of communication protocols to standardize the way that wireless devices, such as cellular telephones and radio transceivers, can be used for Internet access, including e-mail, the World Wide Web, newsgroups, and instant messaging.

The WAP layers are:

1、Wireless Application Environment (WAE)

2、Wireless Session Layer (WSL)

3、Wireless Transport Layer Security (WTLS)

4、Wireless Transport Layer (WTP)

WAP定义无线应用环境、无线会话层、无线安全传输层和无线传输层各个层次。
