CHAPTER SIXTEEN INTEGRATING WIRELESS TECHNOLOGY IN BUSINESS LEARNING OUTCOMES 1. Explain the different wireless network categories 2. Explain the different wireless network business applications WIRELESS NETWORK CATEGORIES PERSONAL AREA NETWORK ?Personal area networks (PAN) Provide communication over a short distance that is intended for use with devices that are owned and operated by a single user ?Bluetooth - Wireless PAN technology that transmits signals over short distances between cell phones, computers, and other devices WIRELESS LAN ?Wireless LAN (WLAN) - A local area network that uses radio signals to transmit and receive data over distances of a few hundred feet ?Wireless fidelity (Wi-Fi) - A means by which portable devices can connect wirelessly to a local area network, using access points that send and receive data via radio waves WIRELESS LAN ?Access point – The computer or network device that serves an as interface between devices and the network ?Wireless access point – Enables devices to connect to a wireless network to communicate with each other ?Multiple-in/multiple-out technology – Multiple transmitters and receivers allowing them to send and receive greater amounts of data than traditional networking devices WIRELESS MAN ?Wireless MAN (WMAN) - A metropolitan area network that uses radio signals to transmit and receive data WIRELESS MAN ?Worldwide Interoperability for Microwave Access (WiMAX) - A communications technology aimed at providing high-speed wireless data over metropolitan area networks WIRELESS WAN - CELLULAR ?Wireless WAN (WWAN) - A wide area network that uses radio signals to transmit and receive data WIRELESS WAN - CELLULAR ?Smart phone - Offer more advanced computing ability and connectivity than basic cell phones ?3G - A service that brings wireless broadband to mobile phones ?Streaming – A method of sending audio and video files over the Internet WIRELESS WAN - SATELLITE ?Satellite - A space station that orbits the Earth receiving and transmitting signals from Earth-based stations over a wide area PROTECTING WIRELESS CONNECTIONS ?Wired equivalent privacy (WEP) - An encryption algorithm designed to protect wireless transmission data ?War chalking - The practice of tagging pavement with codes displaying where Wi-Fi access is available ?War driving - Deliberately searching for Wi-Fi signals while driving by in a vehicle BUSINESS APPLICATIONS OF WIRELESS NETWORKS ?Areas experiencing tremendous growth using wireless technologies include RADIO FREQUENCY IDENTIFICATION (RFID) ?Radio frequency identification (RFID) - Uses electronic tags and labels to identify objects wirelessly over short distances RADIO FREQUENCY IDENTIFICATION (RFID) ?RFID tag - An electronic identification device that is made up of a chip and antenna ?RFID reader (RFID interrogator) - A transmitter/receiver that reads the contents of RFID tags in the area ?Passive RFID tag - Does not have a power source ?Active RFID tag - Contains a transmitter and a power source (typically a battery) RADIO FREQUENCY IDENTIFICATION (RFID) ?Semipassive RFID tag - Uses a battery to run the microchip’s circuitry, but communicate by drawing power from the RFID reader ?Asset tracking - Occurs when a company places active or semi-passive RFID tags on expensive products or assets to gather data on the items’ location with little or no manual intervention ?RFID accelerometer - A device that measures the acceleration (the rate of change of velocity) of an item and is used to track truck speeds or taxi cab speeds ?Chipless RFID tag - Uses plastic or conductive polymers instead of silicon-based microchips, allowing them to be washed or exposed to water without damaging the chip GLOBAL POSITIONING SYSTEM ?Global positioning system (GPS) - A satellite-based navigation system providing extremely accurate position, time, and speed information ?Automatic vehicle location (AVL) – Uses GPS tracking to track vehicles ?Latitude - Represents a north/south measurement of position ?Longitude - Represents an east/west measurement of position GLOBAL POSITIONING SYSTEM ?Geocache - A GPS technology adventure game that posts the longitude and latitude location for an item on the Internet for users to find ?Geocoin - A round coin-sized object uniquely numbered and hidden in geocache ?Estimated time of arrival (ETA) - The time of day of an expected arrival at a certain destination and is typically used for navigation applications ?Estimated time enroute (ETE) - The time remaining before reaching a destination using the present speed and is typically used for navigation applications GEOGRAPHIC INFORMATION SYSTEMS (GIS) ?Geographic information system (GIS) Consists of hardware, software, and data that provide location information for display on a multidimensional map GEOGRAPHIC INFORMATION SYSTEMS (GIS) ?Cartography - The science and art of making an illustrated map or chart ?Edge matching (warping, rubber sheeting) - Occurs when paper maps are laid edge to edge and items that run across maps but do not match are reconfigured to match ?GIS map automation - Links business assets to a centralized system where they can be tracked and monitored over time GEOGRAPHIC INFORMATION SYSTEMS (GIS) ?Spatial data (geospatial data or geographic information) - Identifies the geographic location of features and boundaries on Earth, such as natural or constructed features, oceans, and more ?Geocoding - A spatial databases coding process that assigns a digital map feature an attribute that serves as a unique ID or classification GEOGRAPHIC INFORMATION SYSTEMS (GIS) ?Location based services (LBS) - Applications that use location information to provide a service BENEFITS OF BUSINESS MOBILITY BENEFITS OF BUSINESS MOBILITY ?Enhance mobility ?Provides immediate data access ?Increases location and monitoring capability ?Improves work flow ?Provides mobile business opportunities ?Provides alternative to wiring CHALLENGES OF BUSINESS MOBILITY CHALLENGES OF BUSINESS MOBILITY ?Protecting against theft ?Protecting wireless connections ?Preventing viruses on a mobile device ?Addressing privacy concerns with RFID and LBS LEARNING OUTCOME REVIEW ?Now that you have finished the chapter please review the learning outcomes in your text
