Chapter 1 Introduction

Complying with the IEEE 802.11g standard, WL-U356 provides simple, reliable, high-speed wireless connectivity for both desktop and laptop users. By combining two, state-of-the-art technologies—USB 2.0 and 802.11g—the gadget delivers data at speed up to 54Mbps, five times the speed of existing 802.11b devices, and spares the effort of opening up the case of your desktop computer.

WL-U356 contains an internal patch antenna. It takes advantage of the flexibility and convenience of USB connections without sacrificing performance. Support of 64, 128 and 256-bit WEP encryption plus WPA (Wi-Fi Protected Access) high-level encryption prevents your wireless communications from unauthorized access and ensures secure data transfer.

WL-U356 supports software AP function, which can turn the USB adapter into a compact Access Point instantly. The USB adapter is also backward compatible with 802.11b products, so both 11b and 11g clients can reside on the same network. Easy installation and Hot-plugging offers full mobility and high availability, making the device a perfect choice for users who are getting tired of running cables or in constant need of wireless access.

1.2 Application

Infrastructure

The major difference between Infrastructure network and Ad-hoc wireless network is that the former requires an Access point. For old buildings, open areas, or frequently changing environments, just install the WL-U356 on your desktop or laptop, and thus you can get connected to the wired Ethernet through a wireless Access Point. SOHO users can then access the Internet and share all kinds of data with the other wired or wireless clients within the coverage of wireless signals. For enterprise users, the installation of multiple Access Points to enlarge the coverage of wireless
