Chapter 1 Product Overview
1.1 Introduction
The W-Client delivers the performance and capabilities that every mobile user is
looking for. Embedded with Atheros chipset, it boasts network robustness, stability and
wider coverage for long-range connectivity. Despite its small size, the USB adapter is
big on features; compatibility with wireless 802.11 networks ensures that you can be
connected easily.
Bandwidth needs in the home are increasing rapidly with the introduction of new
devices and services. As broadband infrastructure becomes common in homes, the
demand for multimedia services such as video streaming or VoIP also increases.
Connecting to a wireless LAN without adequate security measures generally opens up
your shared folders to any casual snoopers. To protect your privacy, the USB adapter
is armed with many enhanced wireless security features such as Wi-Fi Protected
Access (WPA), IEEE 802.1x Authentication and 64/128/152-bit WEP (Wired Equivalent
Privacy) to ensure privacy for the heterogeneous mix of users within the same wireless
LAN while maintaining full access to the establishment’s resources.

1.2 Features and Benefits
•Compact and Mobile
The USB adapter is designed especially for the mobile generation. The
casing is compact and sleek, and the antenna is built-in to further preserve
the miniature footprint. Weighing just 20 grams, the device is light enough
to be carried around!
•Fast and Reliable Transmission
The USB adapter can deliver up to 108Mbps wireless throughput. At the
same time, the USB adapter provides reliable wireless transmission to all
wireless users with its auto rate fallback capability.
•USB powered and USB 2.0 fast transfer rate
Leveraging on the USB standard, the USB adapter is powered through its
USB connection and requires no additional power adapter. USB 2.0
standard allows a significant improvement in transfer rate, of up to 40
times that of USB 1.1. You have access to the full 108Mbps transfer rate
of Super-AG on USB 2.0. The small form factor of the USB adapter is
conveniently designed to fit exactly into a USB port without blocking up
neighboring USB ports.
Designed with a USB2.0 interface, the USB adapter can provide 40 times
higher throughput when connected to the USB2.0 slot of your
PC/notebook. It is also backwards compatible with USB1.1 though the
throughput will then be limited to the 12Mbps of the USB1.1 standard.
•Easy Set up
Using your wireless USB adapter is quick and convenient with USB plug-
and –play. The USB adapter is installed externally so you do not have to
open up your PC.
•Highly Secured Traffic
The USB adapter supports wireless security features such as 64/128/152-
bit WEP and the stronger industry standard WPA and 802.1x
authentication to ensure that your data remains secure while in transit.
