Chapter 23

Wireless Internet and m-Business

 

Introduction

 

Wireless technology has developed into one of today’s hottest topics because of its ability to bring the power of communications and the Internet into the hands of users worldwide. The introduction of wireless communications affects many aspects of society, including business management and operations, employee productivity, consumer purchasing behav-ior, marketing strategies and personal communications. As the popularity of wireless ser-vices grows, manufacturers are enabling wireless devices with an increasing array of features and capabilities. For example, many personal digital assistants (PDAs) now oper-ate as cell phones, and vice versa.

 

In this chapter, we explore elements of the wireless Internet and mobile business. We present information regarding wireless marketing, wireless payment options and security and privacy issues. We also introduce wireless programming languages and techniques.

Although we begin our programming discussion with an examination of the Wireless Application Protocol (WAP) and Wireless Markup Language (WML), the chapter covers various programming languages and wireless platforms. These include Java 2 Micro Edi-tion (J2ME), Binary Run-Time Environment for Wireless (BREW), i-mode and Blue-tooth™ wireless technology.

 

In this chapter, we introduce WML wireless programming techniques and examine the use of WML in developing content. WML identifies the elements of a document so that a wireless browser, such as the Openwave™ Mobile Browser, can render the document on the small display screen of a wireless device. We begin with WML because the language provides an excellent foundation in the structuring of data using markup. The chapter first examines WML elements and attributes. Later, we explore the use of the WMLScript scripting language to write programs that enhance the functionality of WAP applications; WMLScript enables the creation of highly appealing and powerful wireless content. We introduce elements of WMLScript programming and present examples that illustrate important features of the language. The chapter also provides an overview of several of WMLScript’s built-in objects and demonstrates their capabilities.

 

We discuss the basics of creating applications that use WML and WMLScript in accor-dance with the Wireless Application Protocol (WAP). WAP is an established standard for accessing information and displaying the information on a wireless device. The chapter presents many simple WAP applications. Further information about WAP can be found at the WAP Forum Web site, www.wapforum.org. In addition, we offer in-depth treat-ments of these and other topics pertaining to wireless communications in our book Wireless Internet and Mobile Business How To Program.
