GLOSSARY ................................................................................................................................ 30 4 1. INTRODUCTION Wireless LAN is local area networking without wires, which uses radio frequencies to transmit and receive data between PCs or other network devices. Wireless LAN is able to configure independent networks and infrastructure networks. The former is suitable for small or temporary peer-to-peer configurations, and the later is offering fully distributed data connectivity via micro cells and roaming. The WLAN PC Card is designed to meet the mobility, performance, security, interoperability, management, and reliability requirements of IEEE 802.11b high data rate standard. It is easy to install the WLAN PC Card on various devices with PCMCIA TYPE II card slot. It is able to communicate with other IEEE 802.11b compatible products to create a wireless LAN in your office or home. 1.1 Features

Typical applications include hard-to-wire buildings, campuses, hospitals/medical offices, warehouse, security huts, exhibition centers, etc.

Temporary LANs for special projects or occasions - Auditors require workgroups at customer sites. Trade shows, exhibitions, retailers, airline, and shipping companies need additional workstations for a peak period of data traffic. 5 1.3 Wireless LAN System 1.3.1 802.11 Ad-Hoc Configuration An 802.11 Ad-Hoc wireless LAN is a group of computers, each equipped with one WLAN PC Card, connected as an independent wireless LAN. Computers in a specific 802.11 Ad-Hoc wireless LAN must be configured at the same radio channel. 802.11 Ad-Hoc wireless LAN is applicable to a departmental scale for a branch or SOHO operation. Figure 1-1 802.11 Ad-Hoc Configuration 1.3.2 Infrastructure Configuration An integrated wireless and wired LAN is called an infrastructure configuration. A group of WLAN PC Cards and an Access Point (AP) is called a Basic Service Set (BSS). Each WLAN PC Card in this BSS can be linked to any computer in the wired LAN infrastructure via the AP. Infrastructure configuration not only extends the accessibility of a WLAN PC Card to the wired LAN, but also doubles the effective wireless transmission range between two WLAN PC Cards. BSS ID is, in essential, the ID of each independent WLAN PC Card. All WLAN PC Cards configured without roaming options in this independent BSS must be configured with BSS ID of that AP. You may need to check BSS ID of your AP by using its vendor supplied program. Infrastructure configuration is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers. Two APs can be used as a point-to-point link between two LANs. LAN interconnection is applicable to a wireless backbone between buildings. 6 Figure 1-2 Infrastructure Configuration The infrastructure configuration supports roaming capability for mobile workers. More than one BSS can be jointly configured as an Extended Service Set (ESS). On account of a continuous connection to the network, users within this ESS can roam freely. All WLAN PC Cards and APs within one ESS must be configured with the same ESS ID. Before setting up an ESS for roaming, it would be helpful to achieve good performance by choosing a feasible radio channel and right places for APs. 7 Figure 1-3 Seamless Roaming 8 2.

GLOSSARY The following glossary is for your reference only, and is not need for the installation of your Wireless LAN PC Card. Wireless Access Point (AP) Any entity that has station functionality and provides access to the distribution services via the wireless medium (WM) for associated stations. Ad-Hoc A network is composed solely of stations within mutual communication range of each other via the wireless medium (WM). An ad hoc network is typically created in a spontaneous manner. The principal distinguishing characteristic of an ad hoc network is its limited temporal and spatial extent. These limitations allow the act of creating and dissolving the ad hoc network to be sufficiently straightforward and convenient so as to be achievable by non-technical users of the network facilities; i.e., no specialized technical skills are required and little or no investment of time or additional resources is required beyond the stations that are to participate in the ad hoc network. The term ad hoc is often used as slang to refer to an independent basic service set (IBSS). BSS (Basic Service Set) An AP associated with several wireless stations. ESS (Extended Service Set) More than one BSS can be configured as an Extended Service Set. An ESS is basically a roaming domain. Ethernet A popular local area data communications network, originally developed by Xerox Corp., which accepts transmission from computers and terminals. Ethernet operates on 10 Mbps baseband transmission over shielded coaxial cable or over shielded twisted pair telephone wire. Fragmentation Threshold Indicates how much of the network resources is devoted to recovering packet errors. The value should remain at its default setting of 2,436. If you experience high packet error rates, you can decrease this value but it will likely decrease overall network performance. Only minor modifications of this value are recommended. Infrastructure The infrastructure includes the distribution system medium (DSM), AP, and portal entities. It is also the logical location of distribution and integration service functions of an extended service set (ESS). An infrastructure contains one or more APs and zero or more portals in addition to the distribution system (DS). IEEE Institute of Electrical and Electronic Engineering LAN Local Area Network Roaming A function that allows one to travel with a mobile end system (wireless LAN mobile station, for example) through the territory of a domain (an ESS, for example) while continuously connecting to the infrastructure. RTS (Request To Send) Threshold It should remain at its default setting of 2,347. A preamble is a signal used to synchronize the transmission timing between two or more systems. A series of transmission pulses are sent before the data to indicate that someone is going to transmit data. This ensures that systems receiving the information correctly when the data transmission starts. SOHO Small Office Home Office SSID Service Set Identifier 30 Wired Equivalent Privacy (WEP) The optional cryptographic confidentiality algorithm specified by IEEE 802.11 is used to provide data confidentiality that is subjectively equivalent to the confidentiality of a wired local area network medium that does not employ cryptographic techniques to enhance privacy. 31
