WLAN

Wireless Local Area Networking (WLAN) enables two or more computers equipped with wireless adapter
cards to share resources.
A wireless network comprises of two or more computers each equipped with wireless adapter cards
forming a network. When the computers are within range of each other each computer has access only to
the resources of the other computer but not to any central server or other resource. This type of basic
configuration is known as an ad hoc network.
A more common and efficient use of a wireless network is one in which two or more computers equipped
with wireless adapter cards are linked to a WLAN Access Point. The Access Point allows each computer
to have access to shared resources, such as a broadband Internet connection, as well as to other
computers on the network. Such a configuration is known as Infrastructure Mode. This is the default
configuration for WLAN in the UT.

ERFORMANCE ERFORMANCE ERFORMANCE ERFORMANCE
The performance of a WLAN network will be influenced by several factors including the number of users
on the network, the location of the antenna, the distance from the antenna and the degree of blocking
from buildings and other infrastructure. Typical operating ranges are 200-300 meters outdoors and 30-60
meters indoors, the performance degrades gradually as the signal strength decreases.

SSID

SSID SSID SSID
A wireless network is identified by a Service Set Identifier or SSID. An SSID is also referred to as a
Network Name because it is a name that identifies a wireless network. Wireless devices that wish to
communicate with each other must be configured with the same SSID. Several Access Points can be set
up using the same SSID so that users can roam from one Access Point to the other without losing
network access. The SSID is broadcast so that any wireless device in range can read the SSID and ask
permission to associate with it. The SSID is not intended as a security measure − it is used only to identify
different networks.
