2. Wi-Fi??? What is Wi-Fi ? Wireless Fidelity 2

3. WI-FI Radio Signal 300 feet range Based on IEEE 802.11 standard Trade name for wireless broadband technology Usually operates in range of 2.4Mhz 3

4. Wi-Fi Wi-Fi refers to an over-the-air connection with a wireless client and a base between two wireless clients it operates in unlicensed frequency bands, any one can set up a Wi-Fi network true freedom if your computer is Wi-Fi CERTIFIED radio (a PC Card or similar device) configured. Wi-Fi certification =ability to connect anywhere 4

5. Wi-Fi Wi-Fi certification comes from the Wi-Fi Alliance, a non-profit international trade organization tests 802.11-based wireless equipment to make sure it meets the Wi-Fi standard 5

6. IEEE wireless standards 6

8. Operates at 2.4GHz radio spectrum

9. 11 Mbps (theoretical speed) - within 30 m Range

10. 4-6 Mbps (actual speed)

11. 100 -150 feet range

12. Most popular, Least Expensive

13. Interference from mobile phones and Bluetooth devices which can reduce the transmission speed.7

14. Penetration of Wi-Fi 8

15. Question -1 What are the business benefits of Wi-Fi networks ? 9

16. United Parcel System Equipped worldwide distribution center with wireless service Cost $120 million 35% productivity gain 10

17. Wells dairy Manufacturers blue bunny brand of ice-cream Equipped with Wi-Fi .Serves 900 employees 10 hrs/week saved in technical support as not many data lines to maintain 11

18. Wi-Fi provides Freedom FREEDOM from WIRE 12

19. Wi-Fi provides Freedom freedom to physically move around your home or business freedom to grow and move an office or business without having to install new cables and wires freedom to be connected while travelling and on the road freedom from drilling holes in walls and floors freedom from dragging cables or hide them under rugs 13

20. Drivers of Wi-Fi Internet becomes part of our life E-mail Wireless devices like laptops Anywhere, anytime access. Wi-Fi components are now on a rapid cost reduction curve as volumes increase to remain constantly interconnected while roaming within the range of a base station 14

21. Benefits contd. Super fast wireless connection ¼ th cost compared to wired N/Ws Low cost and extensive availability of Wi-Fi products Mobility - users can move about almost without restriction Flexibility & scalability Convenience- seamless connectivity Time saving Customized 15

22. After Implementing Wi-Fi High user productivity - employees can work more effectively and efficiently Cost efficiency - accurate design means less wastage and more performance Maximum Return on Investment Improved Quality of Work reducing the costs of network deployment and expansion Competitive edge to business 16

23. Number of users by time of day 17

24. Question 2 What are some of the problems faced by the companies using that are using Wi-Fi networks? What are the solution to those problems? 18

25. GM & Marriot Hotel General Motors has deployed Wi-Fi in 90 manufacturing plants but is holding off on Wi-Fi at its headquarters until next year. Why? 19

26. Marriot hotel across the street Guests at hotel could log on GM N/W Can go away with vital info So GM waiting for new encryption code 20

27. Problems Problem of placement - Frequency spectrum used by IEEE 802.11b is shared by many other systems like Mic wave ovens, cordless phones ,BTetc. This causes interference problem. EmployeeLaptopWi-fiInternet effects productivity HT Brunch-Statistics 30% of employees spend at least an hour online doing personal things Security concern It has a limited bandwidth of about 83.5 MHz. Challenge for the IT dept 21

28. Challenges Two major challenges are Encryption Authentication 22

29. 23

30. Solutions 24

31. Solution Contd. Enhanced security standard 25

32. Solution Contd. No Laptop in important meetings 26

33. Question 3 What are some other business uses for Wi-Fi networks not mentioned in this case? What are their business benefits and challenges? 27

34. Uses Pubs , Restaurants, Coffee shops (e.g. Starbucks) Colleges and Universities (e.g. DTU) Stadiums, casinos, groceries, hospitals and department stores Train stations for Internet connectivity Logistics - Truck drivers can tap the Internet and communicate scheduling and other data back to home base without deviating from their routes(e.g. Walmart does this) VPN on the move in case the city is equipped with wifi 28

35. Benefits Wi-Fi uses unlicensed radio spectrum .So, no licenses to be purchased. reduce associated costs of network connection and expansions. Places where cables cannot be run, such as outdoor areas and historical buildings If sites are close by, such as across the street, a directional antenna can be used to avoid digging trenches under roads to connect the sites. 29

36. Drawbacks Power consumption is fairly high compared to some other standards, making the battery life and heat a concern to some users. Spectrum assignments and operational limitations are not consistent worldwide 30

37. Competing Technologies Bluetooth Wi-MAX 31

38. Conclusion Factors Ranking 32

39. “Once you go wireless, you will never want to use a cable again.” 33
