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.

Access Point Mode: PC with Wireless USB Adapter work as an Access Point (only with WEP). You can save money and make a little network using Your PC+Adapter as an Access Point.

1.2 System Requirements

Before installing the Adapter, your PC should meet the following:

■ PC with available USB V2.0/1.1* slot
Intel® Pentium®III 600Mhz or compatible processor with 128MB RAM
■ Windows 98SE/ME/2000/XP or Vista operating system
■ Minimum 15 Mbytes free disk space for installing the driver and utilities
- CD-ROM drive

*When plug the device in the USB 1.1/1.0 port, the real throughput will be up to 6Mbps only when running 11Mbps or higher speed

- Bridge Adapter: Select the device where you want the wireless packets to be sent to.

The range of radio frequencies used by IEEE 802.11g wireless devices is called a “channel”. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel than an adjacent AP (access point) to reduce interference. Interference occurs when radio signals from different access points overlap causing interference and degrading performance.

Adjacent channels partially overlap however. To avoid interference due to overlap, your AP should be on a channel at least five channels away from a channel that an adjacent AP is using. For example, if your region has 11 channels and an adjacent AP is using channel 1, then you need to select a channel between 6 or 11.

How to configure WEP security:

This function is used to protect wireless communication from eavesdropping.

- Open System: with the same WEP key between the stations, the stations don't need to be authenticated, and this algorithm was set to default. Please select WEP or 802.11x Settings in order to complete the configuration.

- Shared Key: with the same WEP key between the stations in this Authentication algorithm, this type will use packets with encryption by transferring a challenge text which will be acknowledge by both side of the stations. In order to choose which authentication algorithm will be used, you must know which one the station supports this algorithm first. Please select WEP or 802.11x Settings in order to complete the configuration.

If you select 64bit in Hex format, you must type 10 values in the following range (0\~F, hexadecimal), or 64bit in ASCII format, you must type 5 values in the following range (0\~9, A\~Z and a\~z Alphanumeric). If you select 128bit in Hex format, you must type 26 values (0\~F, hexadecimal), or 128bit in ASCII format, you must type 13 values in the following range (0\~9, A\~Z and a\~z Alphanumeric).

	ASCII	HEX
64 bit 5*X	10*Y
128 bit 13*X	26*Y
256bit	29*X	58*Y

X=[(0\~9, A\~Z, a\~z Alphanumeric]

Y=[0\~9, A\~F Hexadecimal]

Be sure that the USB Adapter and the wireless station (AP) were set in the same key.

5 Uninstallation (Windows ME/XP/2000)

To uninstall the Wireless USB Adapter:

- Select Start->All programs->Atlantis->NetFly U54 Wireless Utility and select Uninstall.

• Click OK, then Finish.
• Now You can remove the Adapter.

Frequently Asked Questions

1. Can I run an application from a remote computer over the wireless network?

This will depend on whether or not the application is designed to be used over a network. Consult the application's user guide to determine if it supports operation over a network.

2. Can I play computer games with other members of the wireless network?

Yes, as long as the game supports multiple players over a LAN (local area network). Refer to the game's user guide for more information.

3. What is Spread Spectrum?

Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband transmission, but the trade-off produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned to the right frequency, a spread-spectrum signal looks like background noise. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).

4. What is DSSS? What is FHSS? And what are their differences?

Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier that changes frequency in a pattern that is known to both transmitter and receiver. Properly synchronized, the net effect is to maintain a single logical channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct-Sequence Spread-Spectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip (or chipping code). The longer the chip, the greater the probability that the original data can be recovered. Even if one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can recover the original data without the need for retransmission. To an unintended receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most narrowband receivers.

5. Would the information be intercepted while transmitting on air?

WLAN features two-fold protection in security. On the hardware side, as with Direct Sequence Spread Spectrum technology, it has the inherent security feature of scrambling. On the software side, WLAN offers the encryption function (WEP) to enhance security and access control.

6. What is WEP?

WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 64-bit or 128-bit shared key algorithm, as described in the IEEE 802.11 standard.

7. What is infrastructure mode?

When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with a wired network through a wireless access point.

8. What is roaming?

Roaming is the ability of a portable computer user to communicate continuously while moving freely throughout an area greater than that covered by a single access point. Before using the roaming function, the workstation must make sure that it is the same channel number with the access point of dedicated coverage area.

9. What is ISM band?

The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in the hands of users around the globe.

10. What is the IEEE 802.11g standard?

Approved in June, 2003 as an IEEE standard for wireless local area networks (WLANs), 802.11g offers wireless transmission over relatively short distances at up to 54 megabits per second (Mbps) compared with the 11 megabits per second of the 802.11b (Wi-Fi) standard. Like 802.11b, 802.11g operates in the 2.4 GHz range and is thus compatible with it.
