improved life?
By:-

2. DEFINITION
Wi-Fi (or WiFi) is a Local Area Wireless
Technology that allows an electronic device
to participate in computer networking using
2.4 GHz UHF and 5 GHz SHF ISM radio bands.

3. FUNCTIONALITY
• Many devices can use Wi-Fi, e.g. personal computers, video-game
consoles, smartphones, digital cameras, tablet computers and digital audio
players. These can connect to a network resource such as the Internet via
a wireless network access point.
• Such an access point (or hotspot) has a range of about 20 meters (66 feet)
indoors and a greater range outdoors.
• Hotspot coverage can comprise an area as small as a single room with walls that
block radio waves, or as large as many square kilometres achieved by using
multiple overlapping access points.

4. WIFI TODAY
Now we have WiFi, it’s sometimes harder to
think what we can’t do, rather than what we can.
With WiFi we have the internet instantly at our
fingertips, as long as we have a smartphone,
mobile device or laptop close to hand.

5. LIFE WITHOUT INTERNET
• Nowadays, it’s hard to imagine what life would be like without
the internet.
• Staying in touch with people far away would require posting a
letter.
• Banking involved lengthy queues in the local branch.
• Literature would be taken out from the library, a book to read to
pass the time or some educational content to help with studies.

6. LIFE WITHOUT INTERNET
• Application forms might take several attempts to get spelling and
grammar accurate.
• To plan a journey you would take out a map. A trip into town was
the only way to check out the latest fashions and comparing
prices would require you to visit all the shops and look around.
• Party invites went out by paper, word of mouth or a phone call.

7. WIFI USED AT VARIOUS PLACES
• Wi-Fi provides service in private homes, businesses, as well as in public
spaces at Wi-Fi hotspots set up either free-of-charge or commercially,
often using a captive portal webpage for access.
• Organizations and businesses, such as airports, hotels, and restaurants,
often provide free-use hotspots to attract customers. Enthusiasts or
authorities who wish to provide services or even to promote business in
selected areas sometimes provide free Wi-Fi access.

8. CITY – WIDE WIFI
In the early 2000s, many cities around the world announced
plans to construct city-wide Wi-Fi networks. There are
many successful examples; in 2004, Mysore became India's
first Wi-Fi-enabled city. A company called WiFiyNet has set
up hotspots in Mysore, covering the complete city and a
few ne arby villages.

9. WIFI IN CAMPUS
• Like in our college, there is wifi network connectivity that is easily accessible by
all students.
• The wifi helps students providing internet services for free and helps students in
studies by letting them search and study on internet.
• Students also get the chance to do online courses and the global English
programs in the university itself by the use of internet available through the wifi.
