3Wireless LAN network defined by IEEE 802.11a/b/g standard committeecould be configured as :Ad Hoc wireless LAN.Infrastructure wireless LAN.Ad Hoc network is a group of PCs installed with wireless LAN cards, this groupof PCs is called a BSS (Basic Service Set). PCs in this group can use theirwireless LAN cards to communicate with each other, but can notconnect to the Internet.Ad Hoc Wireless Network Infrastructure Wireless NetworkThe most obvious difference between Infrastructure wireless network and AdHoc wireless network is that the PCs in Infrastructure wireless network canaccess the resource in the Internet through Access Point.Depending on your requirement, you can easily set up your PC’s network to bea “Ad Hoc” or “Infrastructure” wireless network. Generally speaking, if in yournetwork, there is an Access Point in it, we recommend you to set yournetwork as an “Infrastructure”, so it can connect to the Internet.

4To use the WLAN 11n USB Client Adapter with a computing device, the WLANAdapter must be equipped with a proper Interface. All drivers and supportingsoftware for the WLAN Adapter must be installed and configured first.Ask your system administrator for the following information, whichyou may need to provide during driver installation :Your Wireless Client Name.Your Wireless SSID.Your computer’s unique client name and workgroup name. For yournetwork account, your user name and password.Your IP address, gateway address, and subnet mask if you’re notusing a DHCP client.Any computer on a network is identified by a unique network address. Thereare two methods to assign a network address to a computer on a TCP/IPnetwork :Static IP addressing.Dynamic IP addressing (DHCP Client).In network with static IP addressing, the network administrator manuallyassigns 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 thenetwork. You may manually change the IP address in theNetwork Propertiesdialog box.Network using static IP address is easy to set up and do notrequire additional network management software.In network with dynamic IP addressing, a DHCP server in the networkdynamically assigns IP addresses to all clients every time they log on to thenetwork. Network using dynamic IP address requires setting up and running aDHCP Server.

17IEEE 802.11 StandardThe IEEE 802.11 Wireless LAN standards subcommittee, which is formulatinga standard for the industry.Access PointAn internetworking device that seamlessly connects wired and wirelessnetworks together.Ad HocAn Ad Hoc wireless LAN is a group of computers, each with a WLANadapter, connected as an independent wireless LAN. Ad Hoc wireless LANis applicable at a departmental scale for a branch or SOHO operation.BSSIDA specific Ad Hoc LAN is called a Basic Service Set (BSS). Computers in aBSS must be configured with the same BSSID.DHCPDynamic Host Configuration Protocol - a method in which IP addresses areassigned by server dynamically to clients on the network. DHCP is used forDynamic IP Addressing and requires a dedicated DHCP server on thenetwork.Direct Sequence Spread SpectrumThis is the method the wireless cards use to transmit data over the frequencyspectrum. The other method is frequency hopping. Direct sequencespreads the data over one frequency range (channel) while frequencyhopping jumps from one narrow frequency band to another manytimes per second.ESSIDAn Infrastructure configuration could also support roaming capability formobile workers. More than one BSS can be configured as an ExtendedService Set (ESS). Users within an ESS could roam freely between BSSswhile served as a continuous connection to the network wireless stationsand Access Points within an ESS must be configured with the same ESSIDand the same radio channel.EthernetEthernet is a 10/100Mbps network that runs over dedicated home/officewiring. Users must be wired to the network at all times to gain access.GatewayA gateway is a hardware and software device that connects two dissimilar

18systems, such as a LAN and a mainframe. In Internet terminology, a gatewayis another name for a router. Generally a gateway is used as a funnelfor all traffic to the Internet.IEEEInstitute of Electrical and Electronics EngineersInfrastructureAn integrated wireless and wired LAN is called an Infrastructureconfiguration. Infrastructure is applicable to enterprise scale for wirelessaccess to central database, or wireless application for mobile workers.ISM BandThe FCC and their counterparts outside of the U.S. have set aside bandwidthfor unlicensed use in the so-called ISM (Industrial, Scientific andMedical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is beingmade available worldwide. This presents a truly revolutionary opportunityto place convenient high-speed wireless capabilities in the hands of usersaround the globe.Local Area Network (LAN)A LAN is a group of computers, each equipped with the appropriate networkadapter 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 singlebuilding or campus.NetworkA network is a system of computers that is connected. Data, files, andmessages can be transmitted over this network. Networks may be local orwide area networks.ProtocolA protocol is a standardized set of rules that specify how a conversationis to take place, including the format, timing, sequencing and/ or errorchecking.SSIDA Network ID unique to a network. Only clients and Access Points thatshare the same SSID are able to communicate with each other. This stringis case-sensitive.Static IP AddressingA method of assigning IP addresses to clients on the network. In networkswith Static IP address, the network administrator manually assigns an IPaddress to each computer. Once a Static IP address is assigned, a computer

19uses the same IP address every time it reboots and logs on to thenetwork, unless it is manually changed.Temporal Key Integrity Protocol (TKIP)The Temporal Key Integrity Protocol, pronounced tee-kip, is part of theIEEE 802.11i encryption standard for wireless LANs. TKIP is the nextgeneration of WEP, the Wired Equivalency Protocol, which is used tosecure 802.11 wireless LANs. TKIP provides per-packet key mixing, amessage integrity check and a re-keying mechanism, thus fixing theflaws of WEP.Transmission Control Protocol / Internet Protocol (TCP/IP)TCP/IP is the protocol suite developed by the Advanced ResearchProjects Agency (ARPA). It is widely used in corporate Internet works,because of its superior design for WANs. TCP governs how packet issequenced for transmission the network. The term “TCP/IP” is oftenused generically to refer to the entire suite of related protocols.Transmit / ReceiveThe wireless throughput in Bytes per second averaged over two seconds.Wi-Fi AllianceThe Wi-Fi Alliance is a nonprofit international association formed in 1999to certify interoperability of wireless Local Area Network products basedon IEEE 802.11 specification. The goal of the Wi-Fi Alliance’s members isto enhance the user experience through product interoperability. Theorganization is formerly known as WECA.Wi-Fi Protected Access (WPA)The Wi-Fi Alliance put together WPA as a data encryption method for802.11 wireless LANs. WPA is an industry-supported, pre-standard versionof 802.11i utilizing the Temporal Key Integrity Protocol (TKIP),which fixes the problems of WEP, including using dynamic keys.Wide Area Network (WAN)A WAN consists of multiple LANs that are tied together via telephoneservices and / or fiber optic cabling. WANs may span a city, a state, acountry, or even the world.Wired Equivalent Privacy (WEP)Now widely recognized as flawed, WEP was a data encryption methodused to protect the transmission between 802.11 wireless clients andAPs. However, it used the same key among all communicating devices.WEP’s problems are well-known, including an insufficient key length andno automated method for distributing the keys. WEP can be easily

20cracked in a couple of hours with off-the-shelf tools.Wireless LAN (WLAN)A wireless LAN does not use cable to transmit signals, but rather usesradio 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 limitedbandwidth, usually under 11Mbps, and users share the bandwidth withother devices in the spectrum; however, users can operate a spreadspectrum device without licensing from the Federal CommunicationsCommission (FCC).Fragment ThresholdThe proposed protocol uses the frame fragmentation mechanism defined inIEEE 802.11 to achieve parallel transmissions. A large data frame isfragmented into several fragments each of size equal to fragment threshold.By tuning the fragment threshold value, we can get varying fragment sizes.The determination of an efficient fragment threshold is an important issue inthis scheme. If the fragment threshold is small, the overlap part of the masterand parallel transmissions is large. This means the spatial reuse ratio ofparallel transmissions is high. In contrast, with a large fragment threshold, theoverlap is small and the spatial reuse ratio is low. However high fragmentthreshold leads to low fragment overhead. Hence there is a trade-off betweenspatial re-use and fragment overhead.Fragment threshold is the maximum packet size used for fragmentation.Packets larger than the size programmed in this field will be fragmented If youfind that your corrupted packets or asymmetric packet reception (all sendpackets, for example). You may want to try lowering your fragmentationthreshold. This will cause packets to be broken into smaller fragments. Thesesmall fragments, if corrupted, can be resent faster than a larger fragment.Fragmentation increases overhead, so you'll want to keep this value as closeto the maximum value as possible.RTS (Request To Send) ThresholdThe RTS threshold is the packet size at which packet transmission is governedby the RTS/CTS transaction. The IEEE 802.11-1997 standard allows for shortpackets to be transmitted without RTS/CTS transactions. Each station canhave a different RTS threshold. RTS/CTS is used when the data packet sizeexceeds the defined RTS threshold. With the CSMA/CA transmission

21mechanism, the transmitting station sends out an RTS packet to the receivingstation, and waits for the receiving station to send back a CTS (Clear to Send)packet before sending the actual packet data. This setting is useful fornetworks with many clients. With many clients, and a high network load, therewill be many more collisions. By lowering the RTS threshold, there may befewer collisions, and performance should improve. Basically, with a faster RTSthreshold, the system can recover from problems faster. RTS packetsconsume valuable bandwidth, however, so setting this value too low will limitperformance.Beacon IntervalIn addition to data frames that carry information from higher layers, 802.11includes management and control frames that support data transfer. Thebeacon frame, which is a type of management frame, provides the "heartbeat"of a wireless LAN, enabling stations to establish and maintain communicationsin an orderly fashion. Beacon Interval represents the amount of time betweenbeacon transmissions. Before a station enters power save mode, the stationneeds the beacon interval to know when to wake up to receive the beacon(and learn whether there are buffered frames at the access point).Preamble TypeThere are two preamble types defined in IEEE 802.11 specification. A longpreamble basically gives the decoder more time to process the preamble. All802.11 devices support a long preamble. The short preamble is designed toimprove efficiency (for example, for VoIP systems). The difference between thetwo is in the Synchronization field. The long preamble is 128 bits, and theshortis 56 bits.WPA2It is the second generation of WPA. WPA2 is based on the final IEEE 802.11iamendment to the 802.11 standard.Temporal Key Integrity Protocol (TKIP)The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the IEEE802.11i encryption standard for wireless LANs. TKIP is the next generation ofWEP, the Wired Equivalency Protocol, which is used to secure 802.11 wirelessLANs. TKIP provides per-packet key mixing, a message integrity check and are-keying mechanism, thus fixing the flaws of WEP.

22802.1x Authentication802.1x is a framework for authenticated MAC-level access control, definesExtensible Authentication Protocol (EAP) over LANs (WAPOL). The standardencapsulates and leverages much of EAP, which was defined for dial-upauthentication with Point-to-Point Protocol in RFC 2284.Beyond encapsulating EAP packets, the 802.1x standard also defines EAPOLmessages that convey the shared key information critical for wireless security.Advanced Encryption Standard (AES)Security issues are a major concern for wireless LANs, AES is the U.S.government’s next-generation cryptography algorithm, which will replace DESand 3DES.
