  1. CHAPTER SEVEN Networks, Telecommunications, and Mobile Technology

  2. The Telecommunications Revolution • It began with the deregulation of AT&T in 1986 • AT&T sold long distance • 7 baby bells were formed • Since then, there has been much M & A activity • At this point, it was all POTS • Sprint was formed and sold long distance • MCI was formed and sold long distance • Natural gas pipeline companies and others selling bandwidth • Cable TV is not just for television anymore • VOIP (Vonage, Skype and others)

  3. Trends and Focus Items • From proprietary networks to open systems • TCP/IP • XML • From analog signals to digital signals • From copper wires to fiber • Wireless, wireless, wireless • There are different wireless standards

  4. Key Terms (1) • Telecommunication system - enable the transmission of data over public or private networks • Network - a communications, data exchange, and resource-sharing system created by linking two or more computers and establishing standards, or protocols, so that they can work together

  5. Key Terms (2) • Local area network (LAN) - is designed to connect a group of computers in close proximity to each other such as in an office building, a school, or a home. • Wide area network (WAN) - spans a large geographic area, such as a state, province, or country • Metropolitan area network (MAN) - a large computer network usually spanning a city

  6. Key Terms (3) • Virtual private network (VPN) - a way to use the public telecommunication infrastructure (e.g., Internet) to provide secure access to an organization’s network • Valued-added network (VAN) -a private network, provided by a third party, for exchanging information through a high capacity connection

  7. The Internet Revolution • The Internet changes everything (Jeff Bezos – Amazon.com) • The Internet changes nothing (Len Bosac - Cisco)

  8. Metcalfe’s Law • The usefulness of a network equals the square of the number of users • 2,300,000,000(2,300,000,000 – 1)

  9. Using the Net for a Competitive Advantage • Voice over IP (VOIP) • Networking business • Increasing the speed of business • Optimizing business efficiency

  10. Voice Over IP • Skype was one of the first • Vonage • AT&T and Cable providers • Cisco • Many companies use VOIP to reduce telephony charges

  11. Voice Over IP (Illustration)

  12. Increasing the Speed of Business • Bandwidth - is the difference between the highest and the lowest frequencies that can be transmitted on a single medium, and it is a measure of the medium's capacity

  13. Types of Channels • Physical • Twisted pair 2MB to 100MB • Coax (Ethernet) 200MB to 500mb • Fiber 320+ GB • Wireless • Microwave 200MB • Satellite 200+MB • Bluetooth (1MB)

  14. Network Security • Encryption • Dedicated (leased) lines • VPN

  15. Mobility (Terms) • Mobile means the technology can travel with the user, but it is not necessarily in real-time • Hand-held devices that dock when the user returns to the office • Wireless gives users a live (Internet) connection via satellite or radio transmitters

  16. Mobility (Examples) • FedEx and UPS hand-held devices (real-time wireless connections) • Budweiser (Hand-held devices with docking stations) • Season pass scanners

  17. Cell Phones and PDAs • In 10 years, the PC might be obsolete • Blackberries have permeated business • The iPhone • A 25 billion dollar industry in apps • Bandwidth allows for the convergence of voice, video, and data

  18. Cellular Service (Illustration)

  19. The Cellular Revolution

  20. Satellite Technologies • They use microwaves • Terrestrial microwaves • Geosynchronous satellites • Require line of sight • Good for remote locations • Slow upload speeds • Iridium http://www.iridium.com/

  21. Global Positioning Systems • 24 satellites transmit constantly • Your GPS receives these signals and triangulates your position

  22. GPS Illustration

  23. Geographical Information Systems (Introduction) • GIS integrates: • Spatial database • Query engine • Rendering and mapping engine • Use with GPS • Demo at • http://www.esri.com/software/arcgis/arcinfo/about/demos.html

  24. WiMAX • Wide area wi-fi • Sprint, AT&T, Google • WiMAX cells can cover up to 3000 square miles

  25. RFID • This is a hot topic • My Heavenly ski pass has an RFID tag • Retailers used RFID in certain items for loss prevention • Use on shipping containers • Wal-Mart uses RFID on all palletized shipments • Wynn uses them in it’s casino chips

  26. RFID (Privacy Concerns) • Imagine what I could learn with an RFID tag embedded into your credit card

  27. RFID (Types) • Active tags have their own power source • Passive tags get power from the RFID reader

  28. Mobile Workforce Trends • Social networking gets mobilized • Mobile TV • Multi-function devices become cheaper and more versatile • Location-based services • Mobile advertising • Wireless providers move into home entertainment • Wireless security moves to the forefront • Enterprise mobility
