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 know as
Infrastructure Mode. This is the default configuration for WLAN in the UT.
P
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

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.
