Chapter 1   Introduction 
1.  Introduction 
WN8522B 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. 
WN8522B 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.

installed and operated. The end user has to be informed that the FCC 
radio-frequency exposure guidelines for an uncontrolled environment can be 
satisfied. The end user has to also be informed that any changes or 
modifications not expressly approved by the manufacturer could void the user's 
authority to operate this equipment. If the size of the end product is smaller 
than 8x10cm, then additional FCC part 15.19 statement is required to be 
available in the users manual: This device complies with Part 15 of FCC rules.
