16-2 Learning Outcomes 16.1 Explain how a wireless device helps an organization conduct business anytime, anywhere, anyplace 16.2 Describe RFID and how it can be used to help make a supply chain more effective

16-3 Wireless Fidelity (wi-fi) Wireless fidelity (wi-fi) – a means of linking computers using infrared or radio signals Common examples of wireless devices include: –Cellular phones and pagers –Global positioning systems (GPS) –Cordless computer peripherals –Home-entertainment-system control boxes –Two-way radios –Satellite television

16-4 Business Drivers for Wireless Technologies Mobile and wireless are often used synonymously, but actually denote two different technologies –Mobile technology - means the technology can travel with the user, but it is not necessarily in real-time –Wireless technology - gives users a live (Internet) connection via satellite or radio transmitters

16-5 Business Drivers for Wireless Technologies Drivers of wireless technology growth include: –Universal access to information and applications –The automation of business processes –User convenience, timeliness, and ability to conduct business 24x7x365

16-6 Business Drivers for Wireless Technologies Wireless devices changing business include: –Wireless local area network (WLAN) –Cellular phones and pagers –Cordless computer peripherals –Satellite television –WiMax wireless broadband –Security sensor ( OnStar)

16-7 USING CELLULAR TECHNOLOGIES IN BUSINESS Cellular telephones (cell phones) work by using radio waves to communicate with radio antennas (or towers) placed within adjacent geographic areas called cells A telephone message is transmitted to the local cell by the cellular telephone and then is passed from antenna to antenna, or cell to cell

16-9 USING CELLULAR TECHNOLOGIES IN BUSINESS

16-10 Personal Data Assistants Personal digital assistants (PDA) are small, handheld computers capable of entirely digital communications transmission Smartphone - combines the functions of a cellular phone and a PDA in a single device

16-11 WiMAX The main problem with wi-fi access is that hot spots are very small, so coverage is sparse WiMAX - Worldwide Interoperability for Microwave Access is telecommunications technology aimed at providing wireless data over long distances in a variety of ways, from point-to-point links to full mobile cellular type access

16-12 WiMAX A WiMAX system consists of two parts: –A WiMAX tower - A single WiMAX tower can provide coverage to a very large area - as big as 3,000 square miles –A WiMAX receiver - The receiver and antenna could be built into a laptop the way wi-fi access is today

16-15 Wimax Demo Worldwide Interoperability for Microwave Access WiMAX has the potential to do to broadband Internet access what cell phones have done to phone access. WiMax: Next Generation Internet Revolution

16-16 Bluetooth Bluetooth – a telecommunications industry specification that describes how mobile phones, computers, and personal digital assistants (PDAs) can be easily interconnected using a short-range wireless connection

16-17 Bluetooth Bluetooth – an omnidirectional wireless technology/protocol that provides limited-range voice and data transmission over the unlicensed 2.4-GHz frequency band, allowing connections with a wide variety of fixed and portable devices that normally would have to be cabled together

16-18 Video Demo What Is Bluetooth?

16-19 Radio Frequency Identification (RFID) Radio frequency identification (RFID) - use active or passive tags in the form of chips or smart labels that can store unique identifiers and relay this information to electronic readers RFID tag - contains a microchip and an antenna, and typically work by transmitting a serial number via radio waves to an electronic reader, which confirms the identity of a person or object bearing the tag

16-20 New Trends -RFID Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a radio-frequency (RF) signal, and other specialized functions. The second is an antenna for receiving and transmitting the signal. Today, RFID is used in enterprise supply chain management to improve the efficiency of inventory tracking and management.

16-29 Global Positioning System (GPS) Global Positioning System (GPS) - is a "constellation" of 24 well-spaced satellites that orbit the Earth and make it possible for people with ground receivers to pinpoint their geographic location A GPS receiver is a device that determines current latitude, longitude, speed, and direction of movement The location accuracy is anywhere from 100 to 1 meters for most equipment

16-30 Global Positioning System (GPS)

16-31 Global Positioning System (GPS) Geographic information system (GIS) - is designed to work with information that can be shown on a map Some cell phone providers equip their phones with GPS chips that enable users to be located to within a geographical location about the size of a tennis court

16-32 Global Positioning System (GPS) Common GIS uses: –Finding what is nearby –Routing information –Information alerts –Mapping densities –Mapping quantities
