3. LEARNING OBJECTIVES
Discuss the various types of wireless devices and wireless transmission media.
BUSINESS OPPORTUNITIES: Smart phones could be part of a new marketing campaign, based upon location or user preferences.
BUSINESS RISKS: Smart wireless phones may be unable to access regular websites, causing loss of revenue to the target website.

4. LEARNING OBJECTIVES (continued)
Describe wireless networks according to their effective distance.
BUSINESS OPPORTUNITIES: Appropriate wireless systems can enable the organization to effectively handle new products and equipment as the organization grows.
BUSINESS RISKS: Wireless systems purchased may be unable to keep up with organizational growth, to physically send the signal the required distance.

5. LEARNING OBJECTIVES (continued)
Define mobile computing and mobile commerce.
BUSINESS OPPORTUNITIES: Customer service and employee flexibility can be improved through the use of innovative forms of wireless devices.
BUSINESS RISKS: Wireless devices can be used to blur the boundary between personal and work time, increasing the amount of time engaged in work.

6. LEARNING OBJECTIVES (continued)
Discuss the major M-commerce applications.
BUSINESS OPPORTUNITIES: Sales, marketing and geographic information systems can be linked, improving the ability to track products and provide rapid service.
BUSINESS RISKS: Employees may feel an invasion of privacy if geographic positioning and wireless systems are used to track their movements.

7. LEARNING OBJECTIVES (continued)
Define pervasive computing and describe two technologies that underlie this technology.
BUSINESS OPPORTUNITIES: RFID tags or chips in products can result in a better ability to track products, improving customer service and reducing costs.
BUSINESS RISKS: New technologies may be incorrectly installed, increasing costs and reducing effectiveness.

8. LEARNING OBJECTIVES (continued)
Discuss the four major threats to wireless networks.
BUSINESS OPPORTUNITIES: Restrictive wire-based systems can be replaced with more flexible wireless systems, lowering cost and improving productivity.
BUSINESS RISKS: Data communicated could be exposed to unauthorized access.

9. LEARNING OBJECTIVES (continued)
Explain how wireless threats can be mitigated.
BUSINESS OPPORTUNITIES: Reasonable controls can prevent unauthorized access to information, avoiding privacy violations.
BUSINESS RISKS: Excessive controls can slow down employees, making activities cumbersome and more expensive.

13. Wireless Transmission Media (continued)
Radio
Radio transmission uses radio-wave frequencies to send data directly between transmitters and receivers.
Satellite Radio
Satellite radio (digital radio) offers uninterrupted, near CD-quality music that is beamed to your radio from space. XM satellite radio and Sirius have agreed to merge as of mid-2007. 13

14. 7.2 Wireless Computer Networks and Internet Access
Short-range wireless networks
generally have a range of 100 feet or less.
Medium-range wireless networks
are the familiar wireless local area networks (WLANs).
The most common type of medium-range wireless network is Wireless Fidelity (Wi-Fi).
Wide-area wireless networks
connect users to each other and to the Internet over geographically dispersed distances. 14

15. Wide-Area Wireless Networks
Cellular Radio
uses radio waves to provide two-way communication
1st Generation
2nd Generation
2.5 Generation
3rd Generation
Wireless Broadband or WiMax
access range up to 31 miles and data-transfer rate up to 75 Mbps 15

16. 7.3 Mobile Computing and Mobile Commerce
refers to real-time, wireless connection between a mobile device and other computing environments, such as the Internet and an intranet.
Mobility
users carry a mobile device and can initiate a real-time contact with other systems from wherever they happen to be.
Broad reach
users can be reached instantly when they carry an open mobile device. 16

17. Mobile Computing
The characteristics, mobility and broad reach, create five value-added attributes that break the barriers of geography and time:
Ubiquity
Convenience
Instant connectivity
Personalization
Localization of products and services 17

18. Mobile Commerce Mobile Commerce
The development of m-commerce is driven by the following factors:
Widespread availability of mobile devices
No need for a PC
The “Cell phone culture”
Declining prices
Bandwidth improvement 18

19. Mobile Commerce Applications
Financial Services
Mobile Banking
Wireless Electronic Payment Systems
Micropayments
Mobile (Wireless) Wallets
Wireless Bill Payments 19

20. Intrabusiness Applications
Accessing Information
Mobile Portal
aggregates and provides content and services for mobile users that include news, sports, , entertainment, travel and restaurant information; community services; and stock trading.
Voice Portal
a Web site with an audio interface and can also be accessed through a standard phone or cell phone. 20

21. Location-Based Applications
Shopping from Wireless Devices
Location-based Advertising
Location-based Services 21

22. Telemetry Applications
Technicians can use telemetry to identify maintenance problems in equipment;
Doctors can monitor patients and control medical equipment from a distance;
Car manufacturers use telemetry for remote vehicle diagnosis and preventive maintenance. 22

23. 7.5 Wireless Security Four major threats Rogue access point
War driving
Eavesdropping
RF (Radio frequency) jamming 23
