Wireless LAN

Components of a Wireless LAN are

1) Wireless Router
2) Wireless Network card
3) Access point or Repeater

Wireless LAN uses 802.11a,b, and g standards .

WLANs have data transfer speeds ranging from 1 to 54 mbps.

The 802.11n standard can reach 300 to 600 mbps.

A WLAN signal can be broadcast to cover an area with radius of 65 to 300 feet.

Because the wireless signal is broadcast so everybody nearby can share it, several security precautions are necessary so that only authorized users can access WLAN.
