1 Introduction

Thank you for purchasing the 802.11g Turbo Wireless LAN USB Adapter with Reverse SMA Connector.
This USB adapter is designed with a Reverse SMA connector to accommodate attachable antenna,
providing user the flexibility to change with suitable antenna in different environments. It also 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 adapter 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
adapter is connecting to the Routers or APs with the proprietary feature, the wireless network will be
more effective.

For WLAN security issues, this adapter 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 adapter supports WPA2
function, WPA2 provides a stronger encryption mechanism through AES (Advanced Encryption
Standard), which is a requirement for some corporate and government users.

When you use the devices with services such as Voice over Internet Protocol (VoIP) phones,
televisions and MP3 players, how can you speed up the audio, video and voice data to pass through
the wireless network? IEEE 802.11e Quality of Service (QoS) (The Wi-Fi Alliance defined WMM as a
profile of the IEEE 802.11e) extensions for 802.11 networks will help to define the priorities of the data
traffics by the data categories to provide enhanced multimedia support. This adapter supports the
advanced technology for sure.

This adapter is cost-effective, together with the versatile features; it is the best solution for you to build
your wireless network.
