Chapter 1 Introduction
Thank you for purchasing WL-U350 USB Wireless LAN Adaptor. This device is an IEEE 802.11b
Wireless USB Adapter. It can operate in either Ad-Hoc mode (Point to Point/Point to Multipoint
without Access Point) or Infrastructure mode (Point to Point/Point to Multipoint with Access Point).
It operates in 2.4GHz unlicensed ISM band in the home or office environment.
WL-U350 provided with a built-in dipole antenna and is connected to computer through 1 meter USB
cable. Thus, it is capable of being placed practically anywhere on or around your computer to get
better signal quality and longer connection distance.
The WL-U350 is compatible with Windows 98, Me, 2000 and XP. It supports 64-bit and 128-bit WEP
(Wired Equivalent Privacy) Encryption for securing wireless network connection. Its data rate
support 11, 5.5, 2 and 1 Mbps. With its auto-fallback function, the data rate can be move to lower
speed if signal quality is not good enough.
The WL-U350 provides full mobility and seamless roaming feature for mobile users to keep network
connection across access points. Its range of coverage is up to 300 feet indoor and 800 feet
outdoors.

Application
Infrastructure
The WL-U350 provides access to a wired LAN for wireless workstations. An integrated wireless
and wired LAN is called an Infrastructure configuration. A group of WL-U350 PC users and an
Access Point compose a Basic Service Set (BSS). Each WL-U350 PC in a BSS can talk to any
computer in the wired LAN infrastructure via the Access Point.
An Infrastructure configuration extends the accessibility of a WL-U350 equipped PC to a wired
LAN, and doubles the effective wireless transmission range for 2 WL-U350 PCs. Since the Access
