With the introduction of the World Wide Web, electronic commerce has revolutionized traditional commerce and boosted sales and exchanges of merchandise and information. Recently, the emergence of wireless and mobile networks has made possible the admission of electronic commerce to a new application and research subject—mobile commerce, which is defined as the exchange or buying and selling of commodities, services, or information on the Internet through the use of mobile handheld devices. With services provided by mobile commerce, consumers may use the microbrowsers on their cellular phones or PDAs to buy tickets, order meals, locate and book local hotel rooms, even write contracts on the move. In just a few years, mobile commerce has emerged from nowhere to become the hottest new trend in business transactions. NTT DoCoMo’s i-mode (2003) is by far the most successful example of mobile commerce. Introduced in February 1999, i-mode has attracted over 36 million subscribers worldwide. With i-mode, cellular phone users can easily access more than 62,000 Internet sites, as well as specialized services such as e-mail, online shopping and banking, ticket reservations, and personalized ringing melodies that can be downloaded for their phones. The i-mode network structure not only provides access to i-mode and i-mode-compatible contents through the Internet, but also provides access through a dedicated leased-line circuit for added security. i-mode users are charged based on the volume of data transmitted, rather than the amount of time spent connected. In Spring 2001, NTT DoCoMo introduced its next-generation mobile system, based on wideband CDMA (W-CDMA), which can support speeds of 384Kbps or faster, allowing users to download videos and other bandwidth-intensive content with its high-speed packet data communications.

A mobile commerce system is very complex because it involves such a wide range of disciplines and technologies. In general, a mobile commerce system can be divided into six components: (1) mobile commerce applications, (2) mobile stations, (3 mobile middleware, (4) wireless networks, (5) wired networks, and (6) host computers.

To explain how these components work together, the following outline gives a brief description of a typical procedure that is initiated by a request submitted by a mobile user:

  • 1.

    Mobile commerce applications: A content provider implements an application by providing two sets of programs: client-side programs, such as a user interface on a microbrowser, and server-side programs, such as database accesses and updating.

  • 2.

    Mobile stations: Mobile stations present user interfaces to the end users, who specify their requests on the interfaces. The mobile stations then relay user requests to the other components and display the processing results later using the interfaces.

  • 3.

    Mobile middleware: The major purpose of mobile middleware is to seamlessly and transparently map Internet contents to mobile stations that support a wide variety of operating systems, markup languages, microbrowsers, and protocols. Most mobile middleware also encrypts the communication in order to provide some level of security for transactions.

  • 4.

    Wireless networks: Mobile commerce is possible mainly because of the availability of wireless networks. User requests are delivered to either the closest wireless access point (in a wireless local area network environment) or a base station (in a cellular network environment).

  • 5.

    Wired networks: This component is optional for a mobile commerce system. However, most computers (servers) usually reside on wired networks such as the Internet, so user requests are routed to these servers using transport and/or security mechanisms provided by wired networks.

  • 6.

    Host computers: This component is similar to the one used in electronic commerce, which includes three kinds of software. User requests are generally acted upon in this component.

To better illustrate the above procedure, Figure 1 depicts a flowchart showing how a user request is processed by the components in a mobile commerce system (Leavitt, 2000).

Key Terms in this Chapter

Third generation (3G): wireless system that can provide fairly high-speed (384 Kbps) packet-switched wide-area wireless Internet access to support multimedia applications.

Wireless Application Protocol (WAP): an open, global specification that allows users with mobile devices to easily access and interact with information and services instantly

Wi-Fi: IEEE 802.11b (Wi-Fi) is a wireless local area network standard. It operates in an unlicensed radio frequency band at 2.4 GHz and provides data access at 11 Mbps.

SET: the Secure Electronic Transaction (SET) protocol is a technical standard designed to provide security for payment transactions among cardholders, merchants, payment gateways, and certification authorities in Internet.

Wired Equivalent Privacy (WEP): a data link-level protocol that provides security for the IEEE 802.11 WLAN standards. The encryption algorithm used in WEP is a stream cipher based on

Mobile commerce: the exchange or buying and selling of commodities, services, or information on the Internet (wired or wireless) through the use of mobile handheld devices.
