1 Wireless 54Mbps USB Adapter

The Wireless USB Adapter (hereafter called the Adapter) is a high-efficiency wireless LAN Adapter for wireless networking at home, in office or in public places. The data rate can be up to 54 Mbps and auto-negotiated to 48, 36, 24, 18, 12, 9, 6Mbps (IEEE 802.11g), or 11, 5.5, 2, 1Mbps (IEEE802.11b).

With the Adapter, you can roam between conference room and office without being disconnected the LAN cables; in addition, sharing files and printers can be easy tasks. The Wireless USB Adapter is available to Microsoft Windows operating systems (Windows® XP/2000/ME/98SE and Vista) and can be integrated into networking with either Ad-hoc mode (computer-to-computer, without an Access Point), Infrastructure mode (computer-to-access point, an Access Point is required) or Access Point Mode.

The device offers quick and easy access among wired network and wireless network. The Wireless USB Adapter also supports WPA/WPA2 security, it increases the level of data protection and access control for Wireless LAN.

1.1 How the Adapter works

Ad-hoc Mode: An Ad-hoc network is a local area network or other small network, especially one with wireless or temporary plug-in connections, in which some of the network devices are part of the network only for the duration of a communications session. Users in the network can share files, print to a shared printer, and access the Internet with a shared modem. In this kind of network, new devices can be quickly added; however, users can only communicate with other wireless LAN computers that are in this wireless LAN workgroup, and are within range.

Infrastructure Networking Mode: The difference between Infrastructure network and Ad-hoc network is that the former one includes an Access Point. In an Infrastructure network, the Access Point can manage the bandwidth to maximize bandwidth utilization. Additionally, the Access Point enables users on a wireless LAN to access an existing wired network, allowing wireless users to take advantage of the wired networks resources, such as Internet, email, file transfer, and printer sharing. The scale and range of the Infrastructure networking are larger and wider than that of the Ad-hoc networking.
