Chapter 1 Introduction 

Complying  with  the  IEEE  802.11g  standard,  WL-U356  provides  simple,  reliable,  high-speed  wireless 

connectivity for both desktop and laptop users. By combining two, state-of-the-art technologies

USB 2.0 

and 802.11g

the gadget delivers data at speed up to 54Mbps, five times the speed of existing 802.11b 

devices, and spares the effort of opening up the case of your desktop computer. 

WL-U356  contains  an  internal  patch  antenna.  It  takes  advantage  of  the  flexibility  and  convenience  of 

USB connections without sacrificing performance. Support of 64, 128 and 256-bit WEP encryption plus 

WPA  (Wi-Fi  Protected  Access)  high-level  encryption  prevents  your  wireless  communications  from 

unauthorized access and ensures secure data transfer. 

WL-U356 supports software AP function, which can turn the USB adapter into a compact Access Point 

instantly. The USB adapter is also backward compatible with 802.11b products, so both 11b and 11g 

clients can reside on the same network. Easy installation and Hot-plugging offers full mobility and high 

availability, making the device a perfect choice for users who are getting tired of running cables or in 

constant need of wireless access. 

 

1.1 Features 

2.4GHz ISM band, unlicensed operation 

Wireless connectivity without the hassles and cost of running cables 

IEEE 802.11b/g standard compliant 

USB 2.0 A-type standard connector, compatible with USB 1.1 

Up to 54Mbps data rate 

Utilization of Direct Sequence Spread Spectrum plus OFDM modulation to provide 
robust, interference-resistant solution in a multi-user environment 

Support of 64/128/256-bit WEP encryption and WPA (Wi-Fi Protected Access) 
high-level encryption 

Support of Ad-Hoc / Infrastructure mode 

Support of software AP function. 

Support of most popular operating systems including Windows 
98SE/ME/2000/XP/Server 2003 

Plug-and -Play installation

 

 

1.2 Application 

Infrastructure   

The major difference between Infrastructure network and Ad-hoc wireless network is that the former 

requires an Access point. For old buildings, open areas, or frequently changing environments, just 

install  the  WL-U356  on  your  desktop  or  laptop,  and  thus  you  can  get  connected  to  the  wired 

Ethernet through a wireless Access Point. SOHO users can then access the Internet and share all 

kinds of data with the other wired or wireless clients within the coverage of wireless signals. For 

enterprise  users,  the  installation  of  multiple  Access  Points  to  enlarge  the  coverage  of  wireless
