4. Wireless Technology is an alternative to wired
technology, which is commonly used for
connecting devices in wireless mode
Wi-fi a generic term that refers to IEEE 802.11
communication standard for Wireless Local Area
Network
Wi-fi allows an electronic device to exchange
data wirelessly over a computer
Network,including a high-speed internet
connections
5. Wi-Fi Networks use Radio Technologies to transmit
and receive data at high speed:
IEEE 802.11b
IEEE 802.11a
IEEE 802.11g
6. Access Point (AP) - The AP is a wireless LAN
transceiver or “base station” that can connect one or
many wireless devices simultaneously to the Internet.
Wi-Fi cards - They accept the wireless signal and
relay information. They can be internal and external.
Safeguards - Firewalls and anti-virus software protect
networks from uninvited users and keep information
secure
7. A Hotspot is a geographical area that has a readily
accessible wireless network.
Hotspots are equipped with Broad band Internet
connection and one or more Access points that
allow users to access the internet wirelessly
Hotspots can be setup in any public location that
can support an Internet connection.
8. A Wi-Fi hotspot is created by installing an access point
to an internet connection.
An access point acts as a base station.
When Wi-Fi enabled device encounters a hotspot the
device can then connect to that network wirelessly.
A single access point can support up to 30 users and
can function within a range of 100 – 150 feet indoors
and up to 300 feet outdoors.
Many access points can be connected to each other via
Ethernet cables to create a single large network.
10. Speed-slower than cable
Range-affected by various medium
Travels best through open space
Reduced by walls,glass etc..
11. Set Router to Reboot on a Schedule.
Turn an Old Router Into a Wi-Fi Repeater.
Boost Router's Signal with a Bit of Hacking
to find whats the vulnerability if someone
can try to break security system.
Control Bandwidth-Hogging Applications
Thwart Wi-Fi Thieves with Better Security
Get Rid of Interference from Other
Appliances
Use the Latest Wi-Fi Technologies
12. Wi-Fi is a simple and cost effective way to connect
to internet without the need of wires.
It is growing in popularity because of decreasing
costs and the freedom it gives to users.
Wi-fi is one of the fastest growing
technologies.The Demand for Connecting Devices
without the use of cables is increasing everywhere.
Wi-fi can be found on colleges,campus,offices and
in public areas.
