1. Introduction

Thank you for purchasing the IEEE 802.11g Wireless 108Mbps USB Adapter that provides the easiest way to wireless networking. This User Manual contains detailed instructions in the operation of this product. Please keep this manual for future reference.

1.1 IEEE 802.11g Wireless 108Mbps USB Adapter

IEEE 802.11g Wireless 108Mbps 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 108 Mbps and auto-negotiated to 54, 48, 36, 24, 18, 12, 9, 6Mbps (IEEE 802.11g), or 11, 5.5, 2, 1Mbps (IEEE802.11b).

Wireless network security is protected with standard WEP encryption, Wi-Fi Protected Access (WPA) with PSK and WPA, and further enhanced with 802.1x authentication security.

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 LAN adapter is available to Microsoft Windows operating systems (Windows® XP/2000) and can be integrated into networking with either Ad-hoc mode (computer-to-computer, without an Access Point) or Infrastructure mode (computer-to-access point, an Access Point is required).

1.2 Product Features

Fully IEEE 802.11g and 802.11b standards compliant.

- Pen Size which is easy easy to carry provides users the most mobility and flexibility.
- Support USB2.0 and USB1.1 at the same time, especially for USB2.0 the data rate reaches 480Mbytes.

1.3 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.

4.3.1 Link Info

The Link Info screen shows you the status of the USB Adapter, it shows that where the device is connected to, the Network mode, the Channel, the transmit rate and the encryption mode.

There is another dialog box showing the data transmitted and data received. The two signal lines show the Signal Strength and the Link Quality of the device.

Status: Shows the SSID associated, which can be used to identify the wireless network.

SSID: Shows current SSID, which must be the same for the wireless client and AP in order for communication to be established.

Frequency: Shows the current frequency used for wireless network.

Wireless Mode: Shows the current wireless mode used for wireless communication.

Encryption: Shows the current encryption mode used for wireless network.

Tx Rate: Shows the current data rate used for transmitting.

Channel: Shows the current channel for communication.

Link Quality: Shows the link quality of the 108Mbps Wireless Network USB Dongle with the Access Point when operating under Infrastructure mode.

Wireless 108Mbps USB Adapter

Signal Strength: Shows the wireless signal strength of the connection between the 108Mbps Wireless Network USB Dongle with the Access Point.

Data Rate: Shows the statistics of data transfer, and the calculation is based on the number of packets transmitted and received.

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.

4.3.2 Configuration

This is the page where you can change the basic settings of the Access Point with the minimum amount of effort to implement a secure wireless network environment.

SSID: Service Set Identifier, which is a unique name shared among all clients and nodes in a wireless network. The SSID must be identical for each client and nodes in the wireless network.

Wireless Mode: There are two types available for selection

• Infrastructure - to establish wireless communication with LAN and other wireless clients through the use the Access Points.
• Ad-Hoc - to establish point-to-point wireless communication directly with other wireless client devices such as wireless network Adapter.

Hoc Band: There are 3 bands available for selection- 11B.11G and 11G Turbo Channel: The value of channel that AP will operate in. You can select the channel range of 1 to 11 for North America (FCC) domain and 1 to 13 for European (ETSI) domain and 1 to 14 for Japanese domain.

Power Mode: There are 3 modes to choose.

• Continuous Access Mode (default) - the USB Dongle is constantly operating with full power and it consumes the most power.
  Maximum Power Save - the USB Dongle consumes the least power and only operates when there is wireless network activity.
  Power Save - the USB Dongle consumes the moderate level of power.

Preamble: Select Long or Short Preamble type. Preamble is a sequence of bits transmitted at 1Mbps that allows the PHY circuitry to reach steady-state demodulation and synchronization of bit clock and frame start. Two different preambles and headers are defined: the mandatory supported Long Preamble and header, which interoperates with the 1 Mbit/s and 2 Mbit/s DSSS specification (as described in IEEE Std 802.11), and an optional Short Preamble and header (as described in IEEE Std 802.11b). At the receiver, the Preamble and header are processed to aid in demodulation and delivery of the PSDU. The Short Preamble and header may be used to minimize overhead and, thus, maximize the network data throughput. However, the Short Preamble is supported only from the IEEE 802.11b (High-Rate) standard and not from the original IEEE 802.11. That means that stations using Short-Preamble cannot communicate with stations implementing the original version of the protocol. Click "Apply" for the changes to take effect.

4.3.3 Advanced

This is the page where you configure advanced settings of your 108Mbps Wireless Network USB Dongle.

Security: the setting of the Network Encryption. This function is used to protect wireless communication from eavesdropping. A secondary function of encryption is to prevent unauthorized access to a wireless network, and it can be achieved by using the Encryption function.

Encryption Mode:

There are 4 kinds of encryption mode: Disable, Enable(WEP encryption), WPA-PSK, WPA.

1) Disable:

2) Enable(WEP):Click the Enable Encryption to activate the WEP security of the USB Adapter. WEP-Key: WEP (Wired Equivalent Privacy) relies on a secret key that is shared between a mobile station and a base station (Access Point).

Authentication Mode:

• 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.
• 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.
• Auto: It is recommended to select "Auto" if you are not familiar with the setting.

Default Key (Key 1 ~ Key 4):

You can type the key that you want to use from Key#1 to Key #4, and the key that you type will be the encryption between the stations that you connected with.

Key Length, Key Format and WEP Key:

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).

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

Note: After all the settings are completed, click Apply to save the setting.

WEP is not completely secure. If possible please use WPA-PSK.

3)WPA: if WPA is selected, configuration is enabled. Please click the "configuration". The below window is pop up. Then, please select the certificate that user wants to use and enter the server name and login name

4)WPA-PSK: WPA-PSK (Wi-Fi Protected Access pre-shared key) is a simpler version that does not support 802.1x and requires a separate RADIUS server for mutual authentication.

Enter a Passphrase in the WPA-PSK dialog box. This passphrase must be the same on each computer that is connected to the wireless network.

4.3.4 Site Survey

• Make sure that the notebook PC is powered on.
• Make sure that the Cardbus is configured with the same SSID and security options as the other computers in the infrastructure configuration.

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.
