1 Introduction
Thank you for purchasing the 802.11g Wireless LAN USB Adapter. This USB adapter is designed to
comply with IEEE 802.11g Wireless LAN standard and easy to carry with the Mini size. It is suitable for
any Laptop or Desktop computers.
This adaptor supports higher data throughput than the IEEE 802.11g standard (up to 54Mbps). It
supports specific ways to increase the data transfer rate at a time; compress the data and decrease the
waiting time to send the next data to the Routers or APs. This feature is called Turbo Mode. When the
adaptor is connecting to the Routers or APs with the proprietary feature, the wireless network will be
more effective.
For WLAN security issues, this adaptor supports 64/128-bit WEP data encryption that protects your
wireless network from eavesdropping. It also supports WPA (Wi-Fi Protected Access) feature that
combines IEEE 802.1x and TKIP (Temporal Key Integrity Protocol) technologies. Client users are
required to authorize before accessing to APs or AP Routers, and the data transmitted in the network is
encrypted/decrypted by a dynamically changed secret key. Furthermore, this adaptor supports WPA2
function, WPA2 provides a stronger encryption mechanism through AES (Advanced Encryption
Standard), which is a requirement for some corporate and government users.
This adapter is cost-effective, together with the versatile features; it is the best solution for you to build
your wireless network.
