Chapter 1   Introduction 
1.  Introduction 
WN8122A 65 is a dual band wireless 802.11n USB Adapter which enables wireless 
networking systems to attain data communication speeds up to 300 megabits-per-second 
(Mbps), while remaining backward compatible to the existing installed base of Wi-Fi systems 
worldwide. It supports operation to the IEEE 802.11a/b and IEEE 802.11g ,and draft IEEE 
802.11n standards. 
WN8122A 65 will enable a next generation of high-data-rate platforms for operation in the 
2.4 GHz band that deliver a five-fold speed increase. The cost and performance advantages 
will make it an ideal solution for high bandwidth enterprise applications, such as wireless 
video conferencing and large file transfers. It is compatible with 802.11g standard's 
mandatory modulation schemes—Complementary Code Keying (CCK), which is used in 
802.11b, and Orthogonal Frequency Division Multiplexing (OFDM), used in 802.11g and 
draft 802.11n. Using CCK ensures backward-compatibility with the installed Wi-Fi 802.11b 
base, while OFDM provides the speed required for today's high-bandwidth applications. 
1.1  Product Features 
 High speed for wireless LAN connection, RX up at 300 Mbps data rate. 
 Backward compatible to the existing IEEE 802.11a/b/g WLAN infrastructure. 
 User-friendly utility to configure SSID, security setup and site survey.   
 Wireless data encryption with 64, 128 encryption for security. 
 Support USB   
1.2  Applications 
 Home networking for device sharing. 
 Wireless multimedia.
