2 WI-FI???

What is Wi-Fi ?

Wireless Fidelity

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

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

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

6IEEE WIRELESS

STANDARDS

7 IEEE 802.11B

• Appear in late 1999

• Operates at 2.4GHz radio spectrum

• 11 Mbps (theoretical speed) - within 30 m Range

• 4-6 Mbps (actual speed)

• 100 -150 feet range

• Most popular, Least Expensive

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

8PENETRATION OF

WI-FI

9 QUESTION -1

What are the business benefits of Wi-Fi networks ?

10UNITED PARCEL

SYSTEM

Equipped worldwide distribution center with wireless service

Cost $120 million

35% productivity gain

11 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

12WI-FI PROVIDES

FREEDOM

FREEDOM from WIRE

13WI-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

14 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

15 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

16AFTER 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

17NUMBER OF USERS

BY TIME OF DAY

18 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?

19GM & 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?

20

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

21 PROBLEMS

Problem of placement - Frequency spectrum used by IEEE 802.11b is shared by many other systems like Mic wave ovens, cordless phones ,BT etc. This causes interference problem.

EmployeeLaptopWi-fiInternet 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

22 CHALLENGES

Two major challenges are Encryption Authentication

23

24 SOLUTIONS

Tool of intrusion

Powerful, productive

tool

25 SOLUTION CONTD.

Enhanced security standard

26 SOLUTION CONTD.

No Laptop in important meetings

27 QUESTION 3

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

28 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

29 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.

30 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
