5 “ Copyright 2005 John Wiley & Sons Inc.” Chapter Mobile Computing and Commerce: Overview, Benefits, and Drivers Mobile computing. A computing model designed for workers who travel outside the boundaries of their organizations or homes. Mobile Devices. Portable computers such as PDAs and other handhelds. Wireless mobile computing. The combination of mobile devices used in a wireless environment.

6 “ Copyright 2005 John Wiley & Sons Inc.” Chapter 66 Mobile commerce ( m-commerce) Any e-commerce done in wireless environment, especially via the Internet. Personal Digital Assistant (PDA): A handheld wireless computer. Short Messaging Service (SMS): Technology that allows for sending of short text message on some cell phone. Global Positioning System (GPS): A satellite- based tracking system that enables the determination of GPS device’s location. Bluetooth: Chip technology that enables temporary, short- range connection ( data and voice) between wireless devices. Wireless Application Protocol ( WAP): A set of communication protocols designed to enable different kinds of wireless devices to talk to a server installed on a mobile network, so users can access the Internet. Smartphone: Internet- enabled cell phone that can support mobile application

7 “ Copyright 2005 John Wiley & Sons Inc.” Chapter 67 The Attributes of M-computing and M-commerce Mobility implies portability: user can carry a mobile device with them Broad reach: people can be reached at any time. These two characteristics create five value- added attributes that break the barriers of geography and time, ubiquity, convenience, instant connectivity, personalization, and localization of products and services.

8 “ Copyright 2005 John Wiley & Sons Inc.” Chapter 68 The Attributes of M-computing cont… Ubiquity: fill the need for real- time information and communication, independent of the user’s location. Convenience and instant connectivity: easy and fast access the web, intranets, and other mobile devices without booting up a PC or placing a call via a modem. Customization: Information can be customized and sent to individual consumers as an SMS. Localization: knowing where a user is physically at any particular moment is key to offering relevant products and services.

9 “ Copyright 2005 John Wiley & Sons Inc.” Chapter 69 Drivers of M-computing and M- commerce Widespread availability of mobile devices. No Need for a PC. The “ Cell Phone Culture”. Vendor Marketing. Declining Prices and Increasing. Functionalities. Improvement of Bandwidth.

10 “ Copyright 2005 John Wiley & Sons Inc.” Chapter 610 Wireless LAN(WLAN): A local area network (LAN) without the cables; used to transmit and receive data over the airwaves. Wireless access point: An antenna connecting a mobile device ( Laptop or PDA) to a wired local area network. Hotspot: A small geographical perimeter within which a wireless access point provides service to a number of users b: Technical standard developed by the IEEE, on which most of today’s WLANs run; WLANs employing this standard have communication speed of 11 mbps. (Wi-Fi): wireless fidelity. Another name for the b standard on which most WLANs run. 6.2 Wireless Local Area Networks, WI-FI, and Voice Portals

12 “ Copyright 2005 John Wiley & Sons Inc.” Chapter Pervasive Computing The term pervasive computing also goes by the names ubiquitous computing, embedded computing or augmented computing. Pervasive computing: invisible, everywhere computing that is embedded in the objects around us. (RFID) radio frequency identification. Generic term for technologies that use radio waves to automatically identify individual items.

13 “ Copyright 2005 John Wiley & Sons Inc.” Chapter 613 Contextual Computing and Context Awareness Context awareness. Capturing a broad rang of contextual attributes to better understand what the consumer needs and what products or service might be interest. Contextual computing.
