    802.11n  Wireless  USB  Adapter 

Chapter 1 Introduction 

 
 

1.1 Welcome 

 
Thank  you  for  purchasing  Zonet  ZEW2542-802.11n  wireless  USB  adapter.  ZEW2542 
connects you with IEEE802.11n(Draft 2.0) networks at receiving rate up to an incredible 
300Mbps! By using the reflection signal, 802.11n's “Multiple In, Multiple Out” (MIMO) 
technology increases the range and reduces “dead spots” in the wireless coverage area. 
Unlike  ordinary  wireless  networking  of  802.11b/g  standards  that  are  confused  by 
wireless  reflections,  MIMO  can  actually  use  these  reflections  to  increase  four  times 
transmission range of 802.11g products. Besides, when both ends of the wireless link are 
802.11n products, MIMO technology can utilize twice radio band to increase three times 
transmission  speed  of  ordinary  802.11g  standard  products,  and  can  comply  with 
backwards 802.11b/802.11g standards.                                                           

 

Soft  AP  supported  by  ZEW2542  can  help  you  establish  wireless  LAN  networking  with 
lowest  cost.  Besides,  WPS  (PBC  and  PIN)  encryption  method  can  free  you  from 
remembering the long passwords. Complete WMM function makes your voice and video 
more smooth.
