AW-NU138 IEEE 802.11b/g/n USB Wireless Adapter User’s Manual
I. Introduction iiii. Overview. Overview. Overview. Overview Azurewave AW-NU138 USB 2.0 Wireless Adapter is a highly integrated wireless local area network (WLAN) solution to let users enjoy the digital content through the latest wireless technology without using extra cables and cords. It provides easy-to-use, high performance, cost effective and low power solution. Moreover, AW-NU138 enables compatible high-speed wireless connectivity within home, business and public access wireless networks. Compliant with the IEEE 802.11n/g/b standard, AW-NU138 uses Direct Sequence Spread Spectrum (DSSS), Orthogonal Frequency Division Multiplexing (OFDM), BPSK, QPSK, CCK and QAM baseband modulation technologies. When you are using AW-NU138, a high level of integration and full implementation of the power management functions specified in the IEEE 802.11 standard can minimize system power requirements. The AW-NU138 802.11n/g/b Wireless USB Adapter provides up to 128-bit level of WEP security to your wireless data transfers. It is able to run in the operating systems of Windows XP/Vista in either Infrastructure mode or Ad-Hoc mode. Comparing to previous wireless technology, AW-NU138 got great improvements on speed and range. AW-NU138 is able to double the data rate up to 150Mbps. ii.

iii. Product Review 1. Connection Mode ◎Infrastructure Mode Infrastructure mode needs an access point to establish the network, which can provide wireless accesses within valid range for users to communicate with others or transmit data with a wired network. There are several benefits of Infrastructure networking: √ Roaming: a wireless LAN enabled computer can physically move from the operating range of one access point to the other without losing connection. There is a quick association made between new access point and wireless device as the computer traverses from the coverage of one access point to another. √ Range Extension: each wireless LAN enabled computer within the range of access point can communicate with other wireless LAN enabled computers within the effective range from the access point. √ Wired to wireless LAN connection: the access point will establish a bridge between wireless LAN and other wired counterparts. Infrastructure Mode
◎Ad-hoc Mode The difference between Ad-hoc mode and Infrastructure mode is that Ad-hoc mode does not need the access point or router. When you use this mode, your computer will act as a server within the valid range and connect directly to others in the same LAN workgroup. It is recommended to choose this mode when there is no access point showed on your wireless network.
