indicate the 11Mbps Mini PCI Wireless LAN Card/ PCMCIA Wireless LAN Card. Also, the following terms/abbreviations are used interchangeably: • • • • Base Station – Access Point – AP Peer-to-Peer – Ad Hoc Wireless LAN – WLAN Ethernet network – LAN – network III 11Mbps Wireless LAN Card User's Manual This User’s Manual contains information on how to install and configure your Wireless LAN Card. From now on, we will guide you through the correct configuration steps to get your device up and run. IV Chapter 1 Introduction This Wireless LAN Card is an IEEE 802.11b wireless LAN adapter. It allows your computer to connect to a wireless network and to share resources, such as files or printers without being bound to the network wires. Operating in 2.4GHz Direct Sequence Spread Spectrum (DSSS) radio transmission, the Wireless LAN Card transfers data at speeds up to 11Mbps. Both Peer-to-Peer Group (also referred to as Ad-Hoc mode) and Base Station connection (also referred to as Infrastructure mode) are supported. For network security concern, 64/128-bit Wired Equivalent Protection (WEP) algorithm is used. In addition, its standard compliance ensures that it can communicate with any 802.11b networks. 11Mbps Wireless LAN Card User's Manual Wireless LAN Basics This section conations some Wireless LAN basics to help you better understand how the product work together to create a wireless network. Local Area Network (LAN) Simply put, a LAN is a network that exists in a relatively limited area. A network is two or more computers connected together sharing files and peripheral devices such as printers. The Wireless LAN Card allows you to interact with other computers without having to run cables normally associated with networks. This lets you move your computer around while staying connected to your network. There are two ways to use the Wireless LAN Card. One way is to connect directly to one or more Wireless LAN Card equipped computers, forming a Peer-to-Peer (Ad-Hoc) wireless network. The second way is to connect to a Base Station (Access Point) that gives you access to an existing wired LAN, forming an Infrastructure wireless network. Ad-Hoc Mode Ad-Hoc mode offers peer-to-peer connections between workstations, allowing communication between computers within range that have an 802.11b DSSS compatible PC card installed. A wireless Peer-to-Peer Group can also access a wired LAN’s TCP/IP service (such as e-mail and the Internet) by using a TCP/IP software router on an Ethernet equipped PowerBook or notebook. Figure 1-1 Ad-Hoc Mode Chapter 1 Introduction Infrastructure Mode The Infrastructure network uses a Base Station (access point) or several Base Stations as a gateway, linking the wireless network to a wired LAN. As a result, portable workstations or desktops on your wireless network have access to all of the features of your wired LAN including e-mail, Internet access, network printers and files server. Figure 1-2 Infrastructure Mode 11Mbps Wireless LAN Card User's Manual Roaming Multiple Base Stations (Access Points) can be installed to extend the wireless service coverage area for seamless wireless access. Within an extended service area, all Base Stations and wireless clients must have the same Service Set Identity (SSID). Roaming among different Access Points is controlled automatically to maintain the wireless connectivity at all times.

Access Points combined with a distributed system support the creation of multiple radio cells that enable roaming throughout a facility. A network composed solely of stations within mutual communication range of each other (no Access Point connected). Basic Service Set. A set of stations controlled by a single coordination function. A medium used to pass protocol data units that can be used simultaneously in the same volume of space by other channels of the same physical layer, with an acceptably low frame error ratio due to mutual interference. Extended Service Set. A set of one or more interconnected Basic Service Sets (BSSs) and integrated Local Area Networks (LANs) can be configured as an Extended Service Set. Ethernet The most widely used medium access method, which is defined by the IEEE 802.3 standard. Ethernet is normally a shared media LAN; i.e., all the devices on the network segment share total bandwidth. Ethernet networks operate at 10Mbps using CSMA/CD to run over 10BaseT cables. Gateway A network component that acts as an entrance to another network. IEEE 802.11 The IEEE 802.xx is a set of specifications for LANs from the Institute of Electrical and Electronic Engineers (IEEE). Most wired networks conform to 802.3, the specification for CSMA/CD-based Ethernet networks or 802.5, the specification for token ring networks. 802.11 defines the standard for wireless LANs encompassing three incompatible (non-interoperable) technologies: Frequency Hopping Spread Spectrum (FHSS), Direct Sequence Spread Spectrum (DSSS), and Infrared. IEEE standards ensure interoperability between systems of the same type. Infrastructure A wireless network centered about an Access Point. In this environment, the Access Point not only provides communication with the wired network but also mediates wireless network traffic in the immediate neighborhood. IP Internet Protocol. The standard protocol within TCP/IP that defines the basic unit of information passed across an Internet connection by breaking down data messages into packets, routing and transporting the packets over network connections, then reassembling the packets at their destination. IP corresponds to the network layer in the ISO/OSI model. 61 11Mbps Wireless LAN Card User's Manual IP Address ISP Internet Service Provider. An organization that provides access to the Internet. Small ISPs provide service via modem and ISDN while the larger ones also offer private line hookups (T1, fractional T1, etc.). LAN Local Area Network. A communications network that serves users within a defined geographical area. The benefits include the sharing of Internet access, files, and equipment, such as printers and storage devices. Special network cabling (10BaseT) is often used to connect the PCs together. Radio Frequency RF, Terms: GHz, MHz, Hz —The international unit for measuring frequency is Hertz (Hz), equivalent to the older unit of cycles per second. One megahertz (MHz) is one Million-Hertz. One giga hertz (GHz) is one Billion-Hertz. The standard U.S. electrical power frequency is 60 Hz, the AM broadcast radio frequency band is 0.55–1.6 MHz, the FM broadcast radio frequency band is 88–108 MHz, and wireless 802.11 LANs operate at 2.4GHz. SSID Service Set ID. A group name shared by every member of a wireless network. Only client PCs with the same SSID are allowed to establish a connection. Subnet Mask A value that defines whether your computer communicates only within your LAN or communicates outside of your LAN, where it is routed out to the rest of the Internet. A Subnet Mask that has the same first three components (for example, 255.255.255.0) is the routing pattern for a Class C address. TCP 62 An IP address is a 32-bit number that identifies each sender or receiver of information sent across the Internet. An IP address has two parts: the identifier of a particular network on the Internet and an identifier of the particular device (which can be a server or a workstation) within that network. Transmission Control Protocol. The standard transport level protocol that provides the full duplex, stream service on which many applications’ protocols depend. TCP allows a process on one machine to send a stream of data to a process on another. Software implementing TCP usually resides in the operating system and uses the IP to transmit information across the network. Glossary WEP Wired Equivalent Privacy. The optional cryptographic confidentiality algorithm specified by 802.11. The algorithm is being used to provide data confidentiality that is subjectively equivalent to the confidentiality of a wired LAN medium that does not employ cryptographic techniques to enhance privacy.. 63
