802.11N WIRELESS
USB ADAPTER
The 802.11N Wireless USB Adapter (WN7122G) is
another cutting edge introduction in 2.4GHz wireless
communication for 11n wireless network connection. Designed
for both the home and office, this wireless USB2.0 adapter

provides the speed, coverage and security expected by today’s
wireless users. The W220 is IEEE 802.11n
compliant while maintaining full backwards compatibility with the
802.11g and 802.11b standards. This standard utilizes advanced
MIMO (Multiple-In, Multiple-Out) technology to deliver incredible
speed and range. The W220 provides better
performance than existing 802.11g technology. Upgrading to
wireless 11n network provides an excellent solution for sharing
an Internet connection and files such as video, music, photos,
and documents. With security being a key consideration,
W220 supports the WPA and WPA2 wireless
encryption standards, which prevent unauthorized access to
wireless networks and ensure data is secure. Once installed the
WLAN utility allows you to scan for available wireless networks
and manage multiple network profiles so connecting becomes
instantaneous.
