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

“ 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.

“ 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.

“ 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.

“ Copyright 2005 John Wiley & Sons Inc.” Chapter 610 The landscape of mobile computing and commerce

“ Copyright 2005 John Wiley & Sons Inc.” Chapter 611 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

“ Copyright 2005 John Wiley & Sons Inc.” Chapter Mobile Intrabusiness Applications Support of mobile workers with wearable devices such as: Screen, Camera, Touch- panel display, Keyboard, and Speech Translator Job Dispatch

“ Copyright 2005 John Wiley & Sons Inc.” Chapter 616 Intrabusiness Workflow Application Before WirelessWith Wireless Work orders are manually assigned by multiple supervisors and dispatchers Work orders are automatically assigned and routed within minutes for maximum efficiency.. Field service technician commute to dispatch center to pick up paper work orders Home-based filed services technicians receive first work order via mobile terminal and proceed directly to first assignment. Manual record keeping of time, work completed, and billing information. Automated productivity tracking, record keeping and building updates Field service technicians call for new assignments and often wait because of radio traffic or unavailable dispatcher. Electronic transmittal of additional work orders with no waiting time Completed work orders are dropped off at the dispatch center at the end of the day for manual entry into the billing tracking system. Uncompleted orders are manually distributed to available technicians. Overtime changes often result. Technicians close completed work orders from the mobile terminals as they are completed. At the end of shift. The technicians sign off and go home.

“ Copyright 2005 John Wiley & Sons Inc.” Chapter Location-Based Commerce Location based commerce (l. commerce):M- commerce transactions targeted to individuals in specific locations, at specific times.

“ Copyright 2005 John Wiley & Sons Inc.” Chapter 619 L-commerce Technologies Providing location- based services requires the following technologies. Position- determining equipment (PDE): This equipment identifies the location of the mobile device. Mobile positioning center (MPC): The MPC is a server that manages the location information sent from the PDE Location-based technology: The technology consist of groups of servers that combine the position information with geographic- and location- specific content to provide an l- commerce service Geographic content: Geographic content consists of streets, road map, addresses, routes, landmarks, land usage, Zip codes and the like. Location-specific content: Location-specific content is used in conjunction with the geographic content to provide he location of particular services.

“ Copyright 2005 John Wiley & Sons Inc.” Chapter 620 Global Positioning Systems (GPS). A wireless system that uses satellites to enable users to determine their position anywhere on the earth Geographical Information System (GIS). System that integrate GSP data onto digitized map displays. GPS and GIS

“ Copyright 2005 John Wiley & Sons Inc.” Chapter 621 Telemetry Applications Telemetry is the science that measures physical remoteness by means of wireless transmission from a remote source (such as a vehicle) to a receiving station.

“ 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.

“ Copyright 2005 John Wiley & Sons Inc.” Chapter 624 Contextual Computing and Context Awareness Context awareness.

“ Copyright 2005 John Wiley & Sons Inc.” Chapter 627 Technical and other limitations of mobile computing LimitationDescription Insufficient bandwidth Sufficient bandwidth is necessary for widespread use and it must be inexpensive. It will take a few years until 3G is in many places.Wi-FI solves some of the problem. Security standardsUniversal standards were not available in It may take 3 or more years to have them. Power consumption Batteries with long life are needed for mobile computing. Color screens and Wi-FI consume more electricity, but new chips are solving some of the power-consumption problems. Transmission interferences Weather and terrain problems as well as distance-limited connection exist with some technologies. Reception in tunnel and some building is poor GPS accuracyGSP may be accurate in a city with tall buildings WAP limitations According to mofileinfo.com, in 2002 there were only about 50,000 WAP sites (compared to millions of Web sites). WAP still is a cumbersome process to work with. Potential health hazards Potential health damage from cellular radio frequency emission is not known yet. However, more car accidents are related to drivers who were talking (some places bar the use of cell phones while you drive ) also, cell phones may interfere with sensitive medical devices. Legal issues Potential legal issues against manufactures of cell phones and against service provides exist, due to the potential health problems Human interface with deviceScreen and keyboards are too small and uncomfortable and tedious for many people to use Complexity Too many optional add-ons are available (e.g., battery chargers, external keyboards, headset, microphone, cradles). Storing and using the optional add-ons can be a problem
