Chapter 1 Introduction
For higher wireless transfer performance, we are glad to introduce the PLANET 802.11n wireless USB
adapter – WNL-U552. It is a USB 2.0 wireless adapter that can operate in either Ad-Hoc mode (Point to
Point/Point to Multipoint without an Access Point) or Infrastructure mode (Point to Point / Point to
Multipoint with an Access Point) 2.4GHz frequency band; it’s backward compatible with 802.11b and
802.11g for users to create a new wireless environment based on the existing wireless network. With
integrating the latest innovative 802.11n technology, the maximum data rate of WNL-U552 is up to
300Mbps which is almost six times of standard G.
Featuring smart antenna technology, the 802.11n design helps combat distortion and interference, so
the Network Card can send its data streams with greater distances and be more reliable. The
WNL-U552 supports the most convenient security, ” Wi-Fi Protected Setup (WPS) “which is the way to
build connection between wireless network clients and this wireless router. This WNL-U552 supports
two types of WPS, Push-Button Configuration (PBC) and PIN code (key Wireless adapter card pin
number)
For WLAN security issues, the WNL-U552 supports both 64/128-bit WEP (Wired Equivalent Privacy)
and WPA/WPA2 (Wi-Fi Protected Access) for securing wireless network connections. The driver and
utility support most popular operating systems, Windows 2000 / XP and Vista. With advanced features
and high performance capability, the WNL-U552 is an excellent choice for constructing a wide range of
wireless solutions.
The power consumption of the card is also very low. This card provides several levels of power saving
modes allowing user customizes the way of saving the power from his/her portable or handheld
devices.
