Introduction to Wi-Fi
Wi-Fi (or wifi,WiFi) stands for “wireless
Fidelity”. It was introduced by IEEE standard Organisation.Wi-Fi was intended to be used for wireless LAN’s, but is now often also used forInternet access.A wireless n/w standard for Transmitting high speed video & multi media Information.
IEEE 802.11:
• Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the IEEE. This is a standard defining all aspects of Radio Frequency Wireless networking
Wireless Networking
The term wireless networking refers to technology that enables two or more computers to communicate using standard network protocols, but without network cabling. There are two kinds of wireless net Workings.those are:
Types of wireless Networkings
Ad-Hoc or Peer-to Peer Networking
A wireless network can also use an access point, or base station.
• Ad-hoc or peer to peer net working:
• Each computer with a wireless interface can communicate directly with all of the others
• A wireless network can also use an access point, or base station.
There are two types of access points:
Hardware Access Point
Software Access Point
Hard ware access point
• Wireless connected computers using a Hardware Access Point.
Soft ware access point
• Wireless connected computers using a Software Access Point.
• Can I have more than one access point ??
Yes, multiple access points can be connected to a wired LAN.
Roaming
• LAN to LAN Wireless Communications :
RANGE OF A WIRELESS NETWORK:
• Typical indoor ranges are 150-300 feet, but can be shorter if the building construction interferes with radio transmissions.
• Outdoor ranges are quoted up to 1000 feet, but again this depends upon the environment.
Advantages
• We get greater mobility
• We get quick,easy installation
• Its fairly fast
DisAdvantages
• Degradation in performance
• Power consumption is high
• Privacy concerns
