ezWAVE Cards Users’ Guide Version 1.6 Copyright© Widelink 2000 DOC – 2001.02.01Page 4 of 36 Chapter 1 Introduction To The Wireless LANA wireless LAN (WLAN) is a flexible data communication system implemented as anextension to, or as an alternative for, a wired LAN within a building or campus. Usingelectromagnetic waves, WLANs transmit and receive data over the air, minimizing theneed for wired connections. Thus, WLANs combine data connectivity with user mobility,and, through simplified configuration, enable movable LANs. WLANs have gained strongpopularity in a number of vertical markets, including the health-care, retail,manufacturing, warehousing, and academic arenas. These industries have profited fromthe productivity gains of using hand-held terminals and notebook computers to transmitreal-time information to centralized hosts for processing. Today WLANs are becomingmore widely recognized as a general-purpose connectivity alternative for a broad rangeof business customers.1.1 What is Wireless LAN?Wireless LANs use electromagnetic airwaves (radio and infrared) to communicateinformation from one point to another without relying on any physical connection. Radiowaves are often referred to as radio carriers because they simply perform the function ofdelivering energy to a remote receiver. The data being transmitted is superimposed onthe radio carrier so that it can be accurately extracted at the receiving end. This isgenerally referred to as modulation of the carrier by the information being transmitted.Once data is superimposed (modulated) onto the radio carrier, the radio signal occupiesmore than a single frequency, since the frequency or bit rate of the modulatinginformation adds to the carrier.Multiple radio carriers can exist in the same space at the same time without interferingwith each other if the radio waves are transmitted on different radio frequencies. Toextract data, a radio receiver tunes in (or selects) one radio frequency while rejecting allother radio signals on different frequencies.In a typical WLAN configuration, a transmitter/receiver (transceiver) device, called anaccess point, connects to the wired network from a fixed location using standardEthernet cable. At a minimum, the access point receives, buffers, and transmits databetween the WLAN and the wired network infrastructure. A single access point cansupport a small group of users and can function within a range of less than one hundred
ezWAVE Cards Users’ Guide Version 1.6 Copyright© Widelink 2000 DOC – 2001.02.01Page 5 of 36 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 aslong as the desired radio coverage is obtained.End users access the WLAN through wireless LAN adapters, which are implemented asPC cards in notebook computers, or use PCI adapters in desktop computers. WLANadapters provide an interface between the client network operating system (NOS) andthe airwaves (via an antenna). The nature of the wireless connection is transparent tothe NOS.1.2 Wireless LAN Standard and Structure{{{{Wireless LAN Standard – IEEE802.11bThe widespread acceptance of WLANs depends on industry standardization to ensureproduct compatibility and reliability among the various manufacturers. The Institute ofElectrical and Electronics Engineers (IEEE) ratified the original 802.11 specifications in1997 as the standard for wireless LANs. That version of 802.11 provides for 1 Mbps and2 Mbps data rates and a set of fundamental signaling methods and other services. Themost critical issue affecting WLAN demand has been limited throughput. The data ratessupported by the original 802.11 standard are too slow to support most general businessrequirements and have slowed adoption of WLANs. Recognizing the critical need tosupport higher data-transmission rates, the IEEE recently ratified the 802.11b standard(also known as 802.11 High Rate) for transmissions of up to 11 Mbps.With 802.11b, WLANs will be able to achieve wireless performance and throughputcomparable to wired Ethernet. Outside of the standards bodies, wireless industry leadershave united to form the Wire-less Ethernet Compatibility Alliance (WECA).WECA’s mission is to certify cross-vendor interoperability and compatibility of IEEE802.11b wireless networking products and to promote that standard for the enterprise,the small business, and the home. Members include WLAN semiconductormanufacturers, WLAN providers, computer system vendors, and software makers.{{{{Wireless LAN Network Equipment802.11 defines two pieces of equipment, a wireless station, which is usually a PCequipped with a wireless network interface card (NIC), and an access point (AP), whichacts as a bridge between the wireless and wired networks. An access point usually
ezWAVE Cards Users’ Guide Version 1.6 Copyright© Widelink 2000 DOC – 2001.02.01Page 6 of 36 consists of a radio, a wired network interface (e.g., 802.3), and bridging softwareconforming to the 802.1d bridging standard. The access point acts as the base stationfor the wireless network, aggregating access for multiple wireless stations onto the wirednetwork. Wireless end stations can be 802.11 PC Card, PCI.{{{{Wireless LAN Network ConfigurationThe 802.11 standard define two modes: infrastructure mode and ad hoc mode (orindependent or peer-to-peer).yAd Hoc ModeAd hoc mode (also called peer-to-peer mode or an Independent BasicService Set, or IBSS) is simply a set of 802.11 wireless stations thatcommunicate directly with one another without using an access point or anyconnection to a wired network. This mode is useful for quickly and easilysetting up a wireless network anywhere that a wireless infrastructure does notexist or is not required for services, such as a hotel room, convention center,or airport, or where access to the wired network is barred (such as forconsultants at a client site).Figure 1. Ad Hoc ModeyInfrastructure ModeIn infrastructure mode, the wireless network consists of at least one accessIndependent BasicService Set (IBSS)
ezWAVE Cards Users’ Guide Version 1.6 Copyright© Widelink 2000 DOC – 2001.02.01Page 7 of 36 point connected to the wired network infrastructure and a set of wireless endstations. This configuration is called a Basic Service Set (BSS). An ExtendedService 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.Figure 2. Infrastructure Mode{{{{RoamingWireless communication is limited by how far signals carry for given power output.WLANs use cells, called microcells, similar to the cellular telephone system to extendthe range of wireless connectivity. At any point in time, a mobile PC equipped with aWLAN adapter is associated with a single access point and its microcell, or area ofcoverage. Individual microcells overlap to allow continuous communication within wirednetwork. They handle low power signals and “hand off” users as they roam through agiven geographic area.The 802.11 MAC layer is responsible for how a client associates with an access point.Distribution System (DS)Service Set (SS) – MultipleAccess Point (AP)Ethernet (802.3)
ezWAVE Cards Users’ Guide Version 1.6 Copyright© Widelink 2000 DOC – 2001.02.01Page 8 of 36 When an 802.11 client enters the range of one or more APs, it chooses an access pointto associate with (also called joining a Basic Service Set), based on signal strength andobserved packet error rates. Once accepted by the access point, the client tunes to theradio channel to which the access point is set. Periodically it surveys all 802.11 channelsin order to assess whether a different access point would provide it with betterperformance characteristics. If it determines that this is the case, it reassociates with thenew access point, tuning to the radio channel to which that access point is set.Reassociation usually occurs because the wireless station has physically moved awayfrom the original access point, causing the signal to weaken. In other cases,Reassociation occurs due to a change in radio characteristics in the building, or duesimply to high network traffic on the original access point. In the latter case this functionis known as “load balancing,” since its primary function is to distribute the total WLANload most efficiently across the available wireless infrastructure. This process ofdynamically associating and reassociating with APs allows network managers to set upWLANs with very broad coverage by creating a series of overlapping 802.11b cellsthroughout a building or across a campus. To be successful, the IT manager ideally willemploy “channel reuse,” taking care to set up each access point on an 802.11 DSSSchannel that does not overlap with a channel used by a neighboring access point.Figure 3.

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 asyour WEP key value. And all the users who want to communicate with you must usethe same WEP key value.You can select WEP key Disable in Configuration dialog box, then communicationbetween clients and AP are not secured.There are two ways to generate the WEP key. One is by entering any text in thePassphrase: And click on Generate button. It will generate four WEP keys; Key 1, Key2, Key 3, Key 4. You can select any key for the security. If you do not select any key,Key 1 is selected in default.The other way is by entering Key value directly from the keyboard: Select the Keynumber and use that Key for accessing the AP. If the Key is not entered correctly, aclient cannot access any other client or AP. This Key value protects the illegal access tothe wireless network resources. As the wireless channel is more prone to the illegalaccess, WEP provides the users safe wireless LAN network access.CautionIf you use WEP function, your network throughput degrades (your will experience slowtransmission. This case is applied to all different brands of wireless LAN products).

Before installing the system, usersshould perform a site survey to determine the optimum utilization of network componentsand to maximize range, coverage and network performance.Here are some operating and environmental conditions you should consider:•Data RatesRadio signal sensitivity and range are inversely proportional to data bit rates. Themaximum radio range is achieved at the lowest workable data rate. There will be adecrease in receiver threshold sensitivity as the radio data rate increases.•Antenna Type and Placement(PCI card only)Proper antenna configuration is a critical factor in maximizing radio range. As a generalguide, range increases in proportion to antenna height. For a detailed explanation ofantenna types and configurations along with guidelines on selecting antennas forspecific environments, see the documentation that comes with your antenna.•Physical EnvironmentsClear or open areas provide better radio range than closed or filled areas. Also, the lesscluttered the work environment, the greater the range.•ObstructionsA physical obstruction such as metal shelving or a steel pillar can hinder theperformance of the client adapter. Avoid locating the computing device in a locationwhere there is a metal barrier between the sending and receiving antennas.

Forexample, drywall construction allows greater range than concrete blocks. Metal or steelconstruction is a barrier to radio signals.Enhancing CoverageThe system architecture options of the wireless station and ezWAVE Access Pointsprovide for a variety of coverage alternatives and flexibility. The system can be designedto provide a wide coverage area with minimal overlap or coverage with heavy overlap.The latter improves system performance and protection against downtime in the event ofa component failure. By arranging the ezWAVE Access Points so the overlap incoverage area is minimized, a large area can be covered with minimal system cost. Thetotal bandwidth available to each mobile station will depend on the amount of data eachmobile station desires to transfer and the number of stations located in each cell.Seamless roaming is supported as mobile station moves in and out of range of eachezWAVE Access Point, thereby maintaining a constant connection to the wired LAN.Each device in the radio network must be configured with the same Service Set Identifier(SSID) to provide the roaming capability. Multiple systems can operate in the samevicinity. The architecture provides multiple channels, which can coexist in the same areawith virtually no interference to each other. In this mode, each system must beconfigured with different Service Set Identifiers (SSID) and different channels, whichprevent clients from roaming to ezWAVE Access Points from a different wireless system.
