I have used the Microsoft Mobile Explorer 3.0 Emulator and the Ericsson Gateway/ Proxy Demo 1.0 gateway to capture the preceding figures.

Summary

In this chapter, you learned about the basics of a mobile application.Mobile applications are applications that are accessible from various mobile devices. In addition, mobile applications allow you to access a Web site from mobile devices. To create a mobile application, you first need to install the Microsoft Mobile Internet Toolkit.The Mobile Internet Toolkit provides you with the essential tools for creating, testing, and deploying a mobile application. These tools include mobile Web forms, components, and controls.

Next, you learned about the transfer protocol for mobile applications, WAP. WAP is a communication protocol, or a set of rules, that allows a wireless device to access a mobile application. Therefore, to enable a user to access a mobile application, the user needs to have a WAP-enabled mobile device, such as a WAPenabled mobile phone.

Then you learned about the technology used for rendering the mobile applications on a mobile phone, WML. WML is a language based on XML. Similar to XML, WML provides a standard for describing data. The standards defined for describing data are based on the W3C standards.

Finally, you learned to create a simple mobile Web application, MobileTimeRetriever, that can be accessed from a mobile phone. You can use the same code to create a mobile application that can be accessed from a PDA. However, in that case, the transfer protocol used is TCP/IP.
