This manual will assist you in the installing WLAN USB Dongle.
6 2. Wireless LAN basics Wireless LAN network defined by IEEE 802.11b standard committee could be configured as: • Ad Hoc wireless LAN or • Infrastructure wireless LAN Ad Hoc network is a group of notebooks with WLAN PC cards or USB dongles called a BSS (Basic Service Set). These notebooks use their WLAN PC cards or USB dongles to communicate with each other, and notebooks can not connect to the Internet. Figure 2-1 Ad Hoc wireless network The most obvious differentiation between Infrastructure wireless network and Ad Hoc wireless network is that the notebooks in Infrastructure wireless network can make use of the resource in the Internet through Access Point. STA 3STA 1STA 2Access PointInternet Figure 2-2 Infrastructure wireless network To set up your notebook’s network as the type of “Ad Hoc” or “Infrastructure” wireless network depends completely on your requirement. Generally, if your network environment has an Access Point, we recommend that you set it as “Infrastructure” to connect to the Internet. STA 1STA 2STA 3

15 3.2 Configuration Utility WLAN USB dongle uses its own management software. All functions controlled by user are provided by this application. When you plug WLAN USB dongle into the USB port, a new icon- should appear in your icon tray automatically wait a while. If the icon is in red, it means that WLAN USB Dongle configuration is invalid or incomplete. Double click on that icon the screen is shown below. User can navigate through “cards”, by clicking or tapping them with a stylus. In the following we explain the use and meanings of the various card. Monitor The field shows the association to available Access Point with Operating Mode, Channel, Tx Rate Power Management mode and MAC Address of WLAN USB Dongle. When the state is “Associated” means normal flow of operation in infrastructure mode. The PC is connected to Access Point. BSSID is chose in the form of hex digits.
16 “Change” / “Submit” button This button becomes active only when one of the fields has been modified. Pressing “Change” button applies the changed values to the driver. Than pressing “Submit” button saves them to the registry. Network Mode This field allows you to select from a list of supported Network “Modes”. The modes displayed will have two values: “Ad Hoc” and “Infrastructure”. Ad Hoc - This is the 802.11b peer-to-peer mode of operation. All communication is done from Client to Client without the use of an Access Point. 802.11 Ad Hoc networking uses the same SSID for establishing the wireless connection. Infrastructure -This mode of operation requires the presence of an 802.11b Access Point. All communication is done via the Access Point, which relays packets to other wireless Clients in the BSS as well as to modes on a wired network such as Ethernet. Channel There are 14 channels available. The channels differ from country to country. Select the channel to be used. SSID SSID is the group name that will be shared by every member of your wireless network. You will be able to connect with an Access Point, which has the same SSID. Tx Rate The transmission rate at which the data packets are transmitted by client of AP. You can set this to 1Mbps, 2Mbps, 5.5Mbps, 11Mbps or Fully Automatic. Signal Strength / Link Quality The Link Quality and Signal Strength bar graph is only active when the node is in Infrastructure Mode. The bar graph displays the quality and strength of the link between the node and its Access Point. A label summarizes the quality of the Link over the bar graph.
17 Statistics To check the packets status, uses can press the “Statistics” tab and get related statistical figures of data and management packets.
18 Site Survey Click on the site survey tab, all access point within detectable range will be found and their related information will be displayed.
19 Encryption An encryption function can avoid unintended users who are not at the same wireless LAN user group to access or get information. The “Encryption” options allow you to enable 64-bit or 128-bit WEP (wired equivalent privacy) encryption. If an encryption function is not needed, you can just simply tick on the “Disable” box to disable it. By choosing this option you must define the encryption key values of your choice. There are four 5 Hex digit encryption keys available if you select 64 bit WEP or there are four 13 Hex digit encryption keys available if you select 128 bit WEP. WEP Key to use is a mechanism to enable the encryption function. After enabling the WEP users need to select the authentication type, open system key or shared key. Open System with this setting any station in the WLAN can associate with this device to receive and transmitted data. Shared Key with this setting only stations using a share key encryption identified by this device are allowed to associate with it.
20 Advanced In advanced tab, you can change configuration setting such as Preamble Type, Fragmentation Threshold, and RTS/CTS Threshold. Before selecting Short Preamble, make sure that the other stations and AP’s are also supporting this feature. Preamble Type (Short/Long) Preamble is the first subfield of PPDU, which is the appropriate frame format for transmission to PHY (Physical layer). There are two options, Short Preamble and Long Preamble. The Short Preamble option improves throughput performance. Fragmentation Threshold The size at which packets will be fragmented. Choose a setting within a range of 256 to 2346 bytes. RTS/CTS Threshold Minimum packet size requires an RTS/CTS. For packets smaller than this threshold, and RTS/CTS is not sent and the packet is transmitted directly to the WLAN. This is the option for the RTS/ CTS Threshold activation.

23 Glossary IEEE 802.11 Standard The IEEE 802.11 Wireless LAN standards subcommittee, which is formulating a standard for the industry. The objective is to enable wireless LAN hardware from different manufacturers to enteropera. Access Point An internetworking device that seamlessly connects wired and wireless networks together. Ad Hoc An Ad Hoc wireless LAN is a group of computers, each with a WLAN adapter, connected as an independent wireless LAN. Ad Hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation. BSSID A specific Ad Hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be configured with the same BSSID. DHCP Dynamic Host Configuration Protocol - a method in which IP addresses are assigned by server dynamically to clients on the network. DHCP is used for Dynamic IP Addressing and requires a dedicated DHCP server on the network. Direct Sequence Spread Spectrum This is the method the wireless cards use to transmit data over the frequency spectrum. The other method is frequency hopping. Direct sequence spreads the data over one frequency range (channel) while frequency hopping jumps from one narrow frequency band to another many times per second. ESSID An Infrastructure configuration could also support roaming capability for mobile workers. More than one BSS can be configured as an Extended Service Set (ESS). Users within an ESS could roam freely between BSSs while served as a continuous connection to the network wireless stations and Access Points within an ESS must be configured with the same ESSID and the same radio channel. Ethernet Ethernet is a 10/100Mbps network that runs over dedicated home/office wiring. Users must be wired to the network at all times to gain access.
24 Gateway A gateway is a hardware and software device that connects two dissimilar systems, such as a LAN and a mainframe. In Internet terminology, a gateway is another name for a router. Generally a gateway is used as a funnel for all traffic to the Internet. IEEE Institute of Electrical and Electronics Engineers Infrastructure An integrated wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers. ISM Band The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the so-called 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. Local Area Network (LAN) A LAN is a group of computers, each equipped with the appropriate network adapter card connected by cable/air, that share applications, data, and peripherals. All connections are made via cable or wireless media, but a LAN does not use telephone services. It typically spans a single building or campus. Network A network is a system of computers that is connected. Data, files, and messages can be transmitted over this network. Networks may be local or wide area networks. PCMCIA Personal Computer Memory Card International Association. Also a PCMCIA card is also referred to PC Card. Protocol A protocol is a standardized set of rules that specify how a conversation is to take place, including the format, timing, sequencing and/ or error checking.
25 Roaming In an infrastructure network, this is when a wireless PC moves out of range of the previously connected access point and connects to a newly connected access point. Throughout the network environment where access point are deployed, PCs can always be connected regardless of where they are located or roam. SSID A Network ID unique to a network. Only clients and Access Points that share the same SSID are able to communicate with each other. This string is case-sensitive. Simple Network Management Protocol (SNMP) Simple Network Management Protocol is the network management protocol of TCP/IP. In SNMP, agents-which can be hardware as well as software-monitor the activity in the various devices on the network and report to the network console workstation. Control information about each device is maintained in a structure known as a management information block. Static IP Addressing A method of assigning IP addresses to clients on the network. In networks with Static IP address, the network administrator manually assigns an IP address to each computer. Once a Static IP address is assigned, a computer uses the same IP address every time it reboots and logs on to the network, unless it is manually changed. Transmission Control Protocol / Internet Protocol (TCP/IP) TCP/IP is the protocol suite developed by the Advanced Research Projects Agency (ARPA). It is widely used in corporate Internet works, because of its superior design for WANs. TCP governs how packet is sequenced for transmission the network. The term “TCP/IP” is often used generically to refer to the entire suite of related protocols. Transmit / Receive The wireless throughput in Bytes per second averaged over two seconds. Wide Area Network (WAN) A WAN consists of multiple LANs that are tied together via telephone services and / or fiber optic cabling. WANs may span a city, a state, a country, or even the world.
26 Wireless LAN (WLAN) A wireless LAN does not use cable to transmit signals, but rather uses radio or infrared to transmit packets through the air. Radio Frequency (RF) and infrared are the commonly used types of wireless transmission. Most wireless LANs use spread spectrum technology. It offers limited bandwidth, usually under 11Mbps, and users share the bandwidth with other devices in the spectrum; however, users can operate a spread spectrum device without licensing from the Federal Communications Commission (FCC)
