17 IEEE 802.11 StandardThe IEEE 802.11 Wireless LAN standards subcommittee, which is formulating a standard for the industry. Access PointAn internetworking device that seamlessly connects wired and wireless networks together. Ad HocAn Ad Hoc wireless LAN is a group of personal computers, each with a WLAN adapter, connected as an independent wireless LAN. Ad Hoc wireless LAN isapplicable at a departmental scale for a branch or SOHO operation.BSSIDA specific Ad Hoc LAN is called a Basic Service Set (BSS). Personal computers in aBSS must be configured with the same BSSID.DHCPDynamic Host Configuration Protocol - a method in which IP addresses are assigned by server dynamically to clients on the network. DHCP is used for Dynamic 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 sequence spreads the data over one frequency range (channel) while frequency hopping jumps from one narrow frequency band to another many times per second. ESSIDAn Infrastructure configuration could also support roaming capability for mobile workers. More than one BSS can be configured as an ExtendedService Set (ESS). Users within an ESS could roam freely between BSSs while served as a continuous connection to the network wireless stations and Access Points within an ESS must be configured with the same ESSID andthe 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  .SVZZHY`
18 systems, such as a LAN and a mainframe. In Internet terminology, a gateway is another name for a router. Generally a gateway is used as a funnel for all traffic to the Internet.IEEEInstitute of Electrical and Electronics Engineers InfrastructureAn integrated wireless and wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers.ISM BandThe FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the so-called ISM (Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in the hands of users around the globe. Local Area Network (LAN)A LAN is a group of personal computers, each equipped with the appropriate network adapter 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 single building or campus.NetworkA network is a system of personal computers that is connected. Data, files, and messages can be transmitted over this network. Networks may be local or wide area networks. ProtocolA protocol is a standardized set of rules that specify how a conversation is to take place, including the format, timing, sequencing and/ or error checking.SSIDA Network ID unique to a network. Only clients and Access Points that share the same SSID are able to communicate with each other. This string is case-sensitive.Static IP AddressingA method of assigning IP addresses to clients on the network. In networks with Static IP address, the network administrator manually assigns an IPaddress to each personal computer. Once a Static IP address is assigned, a personal computer
19 uses the same IP address every time it reboots and logs on to the network, unless it is manually changed. Temporal Key Integrity Protocol (TKIP)The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the IEEE 802.11i encryption standard for wireless LANs. TKIP is the next generation of WEP, the Wired Equivalency Protocol, which is used to secure 802.11 wireless LANs. TKIP provides per-packet key mixing, amessage integrity check and a re-keying mechanism, thus fixing the flaws of WEP. Transmission Control Protocol / Internet Protocol (TCP/IP)TCP/IP is the protocol suite developed by the Advanced Research Projects Agency (ARPA). It is widely used in corporate Internet works, because of its superior design for WANs. TCP governs how packet is sequenced for transmission the network. The term “TCP/IP” is often used 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 1999 to certify interoperability of wireless Local Area Network products based on IEEE 802.11 specification. The goal of the Wi-Fi Alliance’s members isto enhance the user experience through product interoperability. The organization is formerly known as WECA.Wi-Fi Protected Access (WPA)The Wi-Fi Alliance put together WPA as a data encryption method for 802.11 wireless LANs. WPA is an industry-supported, pre-standard version of 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 telephone services 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 method used to protect the transmission between 802.11 wireless clients and APs. 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
20 cracked 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 uses radio 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 limited bandwidth, usually under 11Mbps, and users share the bandwidth withother devices in the spectrum; however, users can operate a spread spectrum device without licensing from the Federal Communications Commission (FCC).Fragment ThresholdThe proposed protocol uses the frame fragmentation mechanism defined in IEEE 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, the overlap is small and the spatial reuse ratio is low. However high fragment threshold leads to low fragment overhead. Hence there is a trade-off between spatial 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 fragmentation threshold. This will cause packets to be broken into smaller fragments. These small 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 isgoverned by the RTS/CTS transaction. The IEEE 802.11-1997 standard allows for short packets to be transmitted without RTS/CTS transactions.Each station can have a different RTS threshold. RTS/CTS is used when the data packet size exceeds the defined RTS threshold. With the CSMA/CA transmission
21 mechanism, the transmitting station sends out an RTS packet to the receiving station, 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 for networks with many clients. With many clients, and a high network load, there will be many more collisions. By lowering the RTS threshold, there may befewer collisions, and performance should improve. Basically, with a faster RTS threshold, the system can recover from problems faster. RTS packets consume valuable bandwidth, however, so setting this value too low will limitperformance.Beacon IntervalIn addition to data frames that carry information from higher layers, 802.11 includes management and control frames that support data transfer. The beacon frame, which is a type of management frame, provides the "heartbeat" of a wireless LAN, enabling stations to establish and maintain communications in an orderly fashion. Beacon Interval represents the amount of time between beacon transmissions. Before a station enters power save mode, the station needs 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 long preamble 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 the two is in the Synchronization field. The long preamble is 128 bits, and theshort is 56 bits.WPA2It is the second generation of WPA. WPA2 is based on the final IEEE 802.11i amendment to the 802.11 standard. Temporal Key Integrity Protocol (TKIP)The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the IEEE 802.11i encryption standard for wireless LANs. TKIP is the next generation of WEP, the Wired Equivalency Protocol, which is used to secure 802.11 wireless LANs. TKIP provides per-packet key mixing, a message integrity check and are-keying mechanism, thus fixing the flaws of WEP.
22 802.1x Authentication802.1x is a framework for authenticated MAC-level access control, defines Extensible Authentication Protocol (EAP) over LANs (WAPOL). The standard encapsulates 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 EAPOL messages 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 DES and 3DES. !
