Chapter 1   Introduction 
1.    Introduction 
AWN11N-001 is  a wireless 1x1 802.11n  USB Adapter which enables wireless  networking 
systems to attain data communication speeds up to 150 megabits-per-second (Mbps), while 
remaining backward compatible to the existing installed base of Wi-Fi systems worldwide. It 
supports operation to the IEEE 802.11b and IEEE 802.11g ,and draft IEEE 802.11n standards. 
AWN11N-001 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.   
This Wire 802.11N wireless USB Adapter is for use only with compatible UL Listed 
Computer  that  installation  Instruction  detailing  user  installation  of  card  cage

Federal Communication Commission Interference Statement 
This equipment has been tested and found to comply with the limits for a Class B 
digital device, pursuant to Part 15 of the FCC Rules.    These limits are designed to 
provide reasonable protection against harmful interference in a residential installation.   
This equipment generates, uses and can radiate radio frequency energy and, if not 
installed  and  used  in  accordance  with  the  instructions,  may  cause  harmful 
interference  to  radio  communications.    However,  there  is  no  guarantee  that 
interference will not occur in a particular installation.    If this equipment does cause 
harmful  interference  to  radio  or  television  reception,  which  can  be  determined  by 
turning  the  equipment  off  and  on,  the  user  is  encouraged  to  try  to  correct  the 
interference by one of the following measures: 
-  Reorient or relocate the receiving antenna. 
-  Increase the separation between the equipment and receiver. 
-  Connect the equipment into an outlet on a circuit different from that 
to which the receiver is connected. 
-  Consult the dealer or an experienced radio/TV technician for help. 
This  device  complies  with  Part  15  of  the  FCC  Rules.  Operation  is  subject  to  the 
following two conditions: (1) This device may not cause harmful interference, and (2) 
this  device  must  accept  any  interference  received,  including  interference  that  may 
cause undesired operation. 
FCC  Caution:  Any  changes  or  modifications  not  expressly  approved  by  the  party 
responsible for compliance could void the user's authority to operate this equipment. 
IEEE 802.11b or 802.11g operation of this product in the U.S.A. is firmware-limited to 
channels 1 through 11. 
IMPORTANT NOTE: 
FCC Radiation Exposure Statement: 
This  equipment  complies  with  FCC  radiation  exposure  limits  set  forth  for  an 
uncontrolled environment. End users must follow the specific operating instructions 
for  satisfying  RF  exposure  compliance.  To  maintain  compliance  with  FCC  RF 
exposure  compliance  requirements,  please  follow  operation  instruction  as 
documented in this manual.

SAR compliance has been established in typical laptop computer(s) with USB slot, 
and product could be used in typical laptop computer with USB slot. Other application 
like handheld PC or similar device has not been verified and may not compliance with 
related RF exposure rule and such use shall be prohibited. 
The availability of some specific channels and/or operational frequency bands are 
country dependent and are firmware programmed at the factory to match the intended 
destination. The firmware setting is not accessible by the end user.
