ezWAVE Cards Users’ Guide Version 1.6 Chapter 1 Introduction To The Wireless LAN A wireless LAN (WLAN) is a flexible data communication system implemented as an extension to, or as an alternative for, a wired LAN within a building or campus. Using electromagnetic waves, WLANs transmit and receive data over the air, minimizing the need for wired connections. Thus, WLANs combine data connectivity with user mobility, and, through simplified configuration, enable movable LANs.
ezWAVE Cards Users’ Guide Version 1.6 to several hundred feet. The access point (or the antenna attached to the access point) is usually mounted high but may be mounted essentially anywhere that is practical as long as the desired radio coverage is obtained. End users access the WLAN through wireless LAN adapters, which are implemented as PC cards in notebook computers, or use PCI adapters in desktop computers.
ezWAVE Cards Users’ Guide Version 1.6 consists of a radio, a wired network interface (e.g., 802.3), and bridging software conforming to the 802.1d bridging standard. The access point acts as the base station for the wireless network, aggregating access for multiple wireless stations onto the wired network. Wireless end stations can be 802.11 PC Card, PCI. { Wireless LAN Network Configuration The 802.11 standard define two modes: infrastructure mode and ad hoc mode (or independent or peer-to-peer).
ezWAVE Cards Users’ Guide Version 1.6 point connected to the wired network infrastructure and a set of wireless end stations. This configuration is called a Basic Service Set (BSS). An Extended Service Set (ESS) is a set of two or more BSSs forming a single sub-network. Since most corporate WLANs require access to the wired LAN for services (file servers, printers, Inter-net links) they will operate in infrastructure mode. Distribution System (DS) Ethernet (802.
ezWAVE Cards Users’ Guide Version 1.6 When an 802.11 client enters the range of one or more APs, it chooses an access point to associate with (also called joining a Basic Service Set), based on signal strength and observed packet error rates. Once accepted by the access point, the client tunes to the radio channel to which the access point is set. Periodically it surveys all 802.11 channels in order to assess whether a different access point would provide it with better performance characteristics.
ezWAVE Cards Users’ Guide { Version 1.6 BSS, ESS and SS ID The basic service set (BSS) is the basic building block of WLAN network. Minimum WLAN BSS may be consist of only two stations. Using access point (AP) and network distribution systems (DS), WLAN service set can be extended arbitrary size – extended service set (ESS). Each service set has its network ID (SSID). All the service sets within an ESS network can have same service ID so that the ESS can support inter-cell ROAMING.
ezWAVE Cards Users’ Guide Chapter 2 Version 1.6 Before You Start ezWAVE To use the ezWAVE adapter with a computing device (desktop personal computer, notebook, laptop computer, portable or hand-held device), the device must be equipped with an internal or external PC Card Type II or Type III slot. All drivers and supporting software (card and socket services) for the client adapter slot must be loaded and configured.
ezWAVE Cards Users’ Guide Chapter 3 Version 1.6 Installing the PC/PCI Card Adapter on a Windows OS This section provides instructions for installing a PC/PCI adapter on a computer using one of the Windows operating systems. Caution The following procedures and physical connections apply generally to normal and conventional client adapter slots. In the cases of custom or non-conventional equipment, be alert to possible differences in client adapter slot configurations. 3.

ezWAVE Cards Users’ Guide Version 1.6 3.1.2 PC Card (PCMCIA) Network Configuration If you have completed PC card installation, insert the PC card. If you PC detects the PC card, you can find glittering LED and PC sound. Also you will see the PC card icon on the right bottom of your screen. When you install Widelink’s wireless LAN card, all the setup process runs automatically. If you reinstall the install program, it asks the positions of “ezWAVE.inf” and cw10sys.
ezWAVE Cards Users’ Guide Version 1.6 Caution This Process could cause serious problem on your network if you edit wrong data. So, if you do not know how to configure your network option, ask for help from your network administrator. Click on the TCP/IP option for setting the IP address for your computer. Static or DHCP setting. You can select either If you use static IP address then enter the IP value assigned for you, Subnet masking, DNS, Domain/Workgroup name and Gateway address value.

You can see the icon at the right bottom of your screen. Click on that icon will show you the screen as show below. Wireless Link Status Status shows wireless LAN card’s MAC address information. Current Status shows selected channel number and transmit data rate.
ezWAVE Cards Users’ Guide Version 1.6 Throughput (Byte/sec) shows transmission/receiving data rate. Link Quality shows measured radio link quality. If the link quality is bad, your computer may not communicate with other client computers. Otherwise (fair/good/excellent), there will be no problems in communicating with other clients. Signal Strength is almost similar to Link Quality information except for a slight difference. Usually, the quality level moves simultaneous with the Link Quality level.
ezWAVE Cards Users’ Guide Version 1.6 SSID: The Service Set Identifier (SSID) controls access to a given wireless network. This value MUST match the SSID of any and all ezWAVE Access Points that you want to communicate with. If the value does not match, access to the system is not granted. The SSID can be formed by up to 32 case-sensitive characters. Tx Rate: The transmission rate at which the data packets are transmitted by the client or AP. You can set this value to 1~2Mbps, 5.
ezWAVE Cards Users’ Guide Version 1.6 In order to do secure communication over the wireless LAN network, wireless LAN module provides encryption function - WEP. There are two ways to generate WEP key. This key is important in protecting the illegal access to the wireless networks. If you want to use WEP function, the AP’s WEP key value must be set exactly same as your WEP key value. And all the users who want to communicate with you must use the same WEP key value.
ezWAVE Cards Users’ Guide Version 1.6 3.2 PCI Card Installation This section describes the procedures for installing the client adapter. Before You Start For the client adapter to be used with a computing device, the device must be equipped with a PCI or ISA expansion slot. Check the documentation that came with your computer for details on the differences between PCI and ISA expansion slots.
ezWAVE Cards Users’ Guide Version 1.6 faced out of your computer and be visible when you put the cover back on. The bottom edge of the card is a connector, which you will insert into an empty expansion slot in your computer. 3.2.1 Installing PCI Card Adapter 1. Turn off the computer and all its components. 2. Remove the computer cover. 3. Remove the screw from the top of the CPU back panel above an empty expansion slot. This screw is used to hold the metal bracket on the back panel. 4.
ezWAVE Cards Users’ Guide Version 1.6 Caution Do not force the client adapter into the slot. Forcing it will damage both the card and the slot. If the card does not go in easily, remove the card and reinsert it. 6. Reinstall the screw to the top of the CPU back panel. 7. The client adapter comes with one 2dBi dipole antenna. With the unit powered off, attach the antenna to the antenna connector on the client adapter. Caution Do not over-tighten the antenna connector; finger-tight is sufficient.
ezWAVE Cards Users’ Guide Version 1.6 3.2.2 Installing PCI Card Driver The installation process of PCI card driver program is the same as that of PC card installation. So, you may refer above 3.1.1 Installing the PC Card Driver for Windows Operating Systems. 3.2.3 PCI Card Network Configuration The installation process of PCI card driver program is the same as that of PC card installation. So you may refer to the above 3.1.
