· Wi-Fi or wireless fidelity is meant for to be used when referring any type of 802.11 network, whether 802.11, 802.11a and dual band.
· Wi-Fi devices tested by the “Wi-Fi alliance” are used around the world and allow users to have Wi-Fi capable device like a PDA or Laptop to connect anywhere there is availability of Wi-Fi access point.
· There are currently three standards that are used to signify the speed of the connection.
o 802.11a and 802.11b are the capable of 54 Mbps
o 802.11b/second because it can transmit the data at 11 Mbps.
· Wireless Fidelity is a fastest growing wireless technology that will probably be as common as phone lines and electric devices.
· Wireless fidelity is planned to be used with the wireless devices but it is most commonly used for internet access.
· Wi-Fi you can connect computers in your home, office or anywhere without the need of wires.
· The computers can just connect to the network that uses radio waves.
How does WI-FI work?
· Wi-Fi is the wireless technology to handle the networking/communication.
· Wi-Fi allocates internet connection globally and to be transmitted by the radio waves.
· Radio waves are transmitted from antenna and Wi-Fi receivers pick them up.
· When a user receives the Wi-Fi signals, a wireless internet connection is produced and a user is prompted to provide the user name and password if required to establish a wireless connection.
What is Wi-Fi Security?
· Wi-Fi maintains certain security issues.
· WEP or Wired Equivalent Privacy is used in the physical and data link layers.
· WEP was planned to provide the wireless security by protecting the data, while it transmits from one point to another.
· Wi-Fi networking usually maintained inside a building premises.
· The data transmission in the Wi-Fi is protected by Wireless LANs but due to the fact that data travels over the radio waves so there are chance that data can be exposed and capture.
