Chapter 3 Wireless LAN Network

This chapter provides background information on wireless LAN network.

This section describes applications of IEEE 802.11n Wireless LAN USB Adapter.

The SSID is the unique ID used by Access Points and stations to identify a wireless Network.

Wireless clients associating to any Access Point must have the same SSID. The default setting is

ANY, which allows your IEEE 802.11n Wireless Network USB Adapter to automatically associate

to any Access Point (Infrastructure mode) in the vicinity of your wireless adapter. The ESS ID can

be set up to 32 characters and is case sensitive.

A radio frequency used by a wireless device is called a channel.

The IEEE 802.11n Wireless Network USB Adapter support various transmit (data) rate. It includes

Auto, 1 or 2 Mbps, 5.5 Mbps, 11 Mbps and up to 300Mbps. In most networking scenarios, the

factory default "Auto" setting proves the most efficient. This setting allows your IEEE 802.11n

Wireless Network USB Adapter to operate at the maximum transmit (data) rate. When the

communications quality drops below a certain level, the Wireless Network USB Adapter will

automatically switch to a lower data rate. Transmission at lower data speed is usually more

reliable. However, when the communications quality improves again, the Wireless Network USB

Adapter will gradually increase the transmit (data) rate again until it reaches the highest available

transmit rate.

Note: Actual speeds attained also depend on the distance from the AP, noise, etc.
