Networks using the TCP/IPprotocol route messages based on the IP address of the destination. The format of an IP address isa 32-bit numeric address written as four numbers separated by periods. Each number can be zero to255. For example, 191.168.1.254 could be an IP address.The MAC (Media Access Control) address is your computer's unique hardware number. (On anEthernet LAN, it's the same as your Ethernet address.) When you're connected to the Internet fromyour computer (or host as the Internet protocol thinks of it), a correspondence table relates your IPaddress to your computer's physical (MAC) address on the LAN.To find your PC’s IP and MAC address,üOpen the Command program in the Microsoft Windows.üType in ipconfig /all then press the Enter button. ØYour PC’s IP address is the one entitled IP Address and your PC’s MAC address is the oneentitled Physical Address.5.2 What is Wireless LAN?A wireless LAN (WLAN) is a network that allows access to Internet without the need for any wiredconnections to the user’s machine.5.3 What are ISM bands?ISM stands for Industrial, Scientific and Medical; radio frequency bands that the FederalCommunications Commission (FCC) authorized for wireless LANs. The ISM bands are located at915 +/- 13 MHz, 2450 +/- 50 MHz and 5800 +/- 75 MHz.5.4 How does wireless networking work?The 802.11 standard define two modes: infrastructure mode and ad hoc mode. In infrastructuremode, the wireless network consists of at least one access point connected to the wired networkinfrastructure and a set of wireless end stations. This configuration is called a Basic Service Set(BSS). An Extended Service Set (ESS) is a set of two or more BSSs forming a single subnetwork.Since most corporate WLANs require access to the wired LAN for services (file servers, printers,Internet links) they will operate in infrastructure mode.
FREQUENTLY ASKED QUESTIONS (FAQ)-55-Example 1: wireless Infrastructure Mode Ad hoc mode (also called peer-to-peer mode or an Independent Basic Service Set, or IBSS) issimply a set of 802.11 wireless stations that communicate directly with one another without using anaccess point or any connection to a wired network. This mode is useful for quickly and easily settingup a wireless network anywhere that a wireless infrastructure does not exist or is not required forservices, such as a hotel room, convention center, or airport, or where access to the wired networkis barred (such as for consultants at a client site).Example 2: wireless Ad Hoc Mode5.5 What is BSSID?A six-byte address that distinguishes a particular a particular access point from others. Also knowas just SSID. Serves as a network ID or name.5.6 What is ESSID?The Extended Service Set ID (ESSID) is the name of the network you want to access. It is used toidentify different wireless networks.5.7 What are potential factors that may causes interference?Factors of interference:OObstacles: walls, ceilings, furniture… etc.OBuilding Materials: metal door, aluminum studs.OElectrical devices: microwaves, monitors and electrical motors.Solutions to overcome the interferences:
-56-üMinimizing the number of walls and ceilings.üPosition the WLAN antenna for best reception. üKeep WLAN devices away from other electrical devices, eg: microwaves, monitors, electricmotors, … etc.üAdd additional WLAN Access Points if necessary. 5.8 What are the Open System and Shared Key authentications?IEEE 802.11 supports two subtypes of network authentication services: open system and sharedkey. Under open system authentication, any wireless station can request authentication. The stationthat needs to authenticate with another wireless station sends an authentication management framethat contains the identity of the sending station. The receiving station then returns a frame thatindicates whether it recognizes the sending station. Under shared key authentication, each wirelessstation is assumed to have received a secret shared key over a secure channel that is independentfrom the 802.11 wireless network communications channel.5.9 What is WEP?An optional IEEE 802.11 function that offers frame transmission privacy similar to a wired network.The Wired Equivalent Privacy generates secret shared encryption keys that both source anddestination stations can use to alert frame bits to avoid disclosure to eavesdroppers.WEP relies on a secret key that is shared between a mobile station (e.g. a laptop with a wirelessEthernet card) and an access point (i.e. a base station). The secret key is used to encrypt packetsbefore they are transmitted, and an integrity check is used to ensure that packets are not modifiedin transit.5.10 What is Fragment Threshold?The proposed protocol uses the frame fragmentation mechanism defined in IEEE 802.11 to achieveparallel transmissions. A large data frame is fragmented into several fragments each of size equal tofragment threshold. By tuning the fragment threshold value, we can get varying fragment sizes. Thedetermination of an efficient fragment threshold is an important issue in this scheme. If the fragmentthreshold is small, the overlap part of the master and parallel transmissions is large. This means thespatial reuse ratio of parallel transmissions is high. In contrast, with a large fragment threshold, theoverlap is small and the spatial reuse ratio is low. However high fragment threshold leads to lowfragment 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 thesize programmed in this field will be fragmented.If you find that your corrupted packets or asymmetric packet reception (all send packets, forexample). You may want to try lowering your fragmentation threshold. This will cause packets to bebroken into smaller fragments. These small fragments, if corrupted, can be resent faster than alarger fragment. Fragmentation increases overhead, so you'll want to keep this value as close to themaximum value as possible.5.11 What is RTS (Request To Send) Threshold?The RTS threshold is the packet size at which packet transmission is governed by the RTS/CTStransaction. 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 datapacket size exceeds the defined RTS threshold. With the CSMA/CA transmission mechanism, thetransmitting station sends out an RTS packet to the receiving station, and waits for the receivingstation to send back a CTS (Clear to Send) packet before sending the actual packet data.
FREQUENTLY ASKED QUESTIONS (FAQ)-57-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 be fewer collisions,and performance should improve. Basically, with a faster RTS threshold, the system can recoverfrom problems faster. RTS packets consume valuable bandwidth, however, so setting this value toolow will limit performance.5.12 What is Beacon Interval?In addition to data frames that carry information from higher layers, 802.11 includes managementand control frames that support data transfer. The beacon frame, which is a type of managementframe, provides the "heartbeat" of a wireless LAN, enabling stations to establish and maintaincommunications in an orderly fashion.Beacon Interval represents the amount of time between beacon transmissions. Before a stationenters power save mode, the station needs the beacon interval to know when to wake up to receivethe beacon (and learn whether there are buffered frames at the access point).5.13 What is Preamble Type?There are two preamble types defined in IEEE 802.11 specification. A long preamble basically givesthe decoder more time to process the preamble. All 802.11 devices support a long preamble. Theshort preamble is designed to improve efficiency (for example, for VoIP systems). The differencebetween the two is in the Synchronization field. The long preamble is 128 bits, and the short is 56bits.5.14 What is SSID Broadcast?Broadcast of SSID is done in access points by the beacon. This announces your access point(including various bits of information about it) to the wireless world around it. By disabling thatfeature, the SSID configured in the client must match the SSID of the access point.Some wireless devices don't work properly if SSID isn't broadcast (for example the D-link DWL-120USB 802.11b adapter). Generally if your client hardware supports operation with SSID disabled, it'snot a bad idea to run that way to enhance network security. However it's no replacement for WEP,MAC filtering or other protections.5.15 What is Wi-Fi Protected Access (WPA)?Wi-Fi’s original security mechanism, Wired Equivalent Privacy (WEP), has been viewed asinsufficient for securing confidential business communications. A longer-term solution, the IEEE802.11i standard, is under development. However, since the IEEE 802.11i standard is not expectedto be published until the end of 2003, several members of the WI-Fi Alliance teamed up withmembers of the IEEE 802.11i task group to develop a significant near-term enhancement to Wi-Fisecurity. Together, this team developed Wi-Fi Protected Access.To upgrade a WLAN network to support WPA, Access Points will require a WPA software upgrade.Clients will require a software upgrade for the network interface card, and possibly a software updatefor the operating system. For enterprise networks, an authentication server, typically one thatsupports RADIUS and the selected EAP authentication protocol, will be added to the network.5.16 What is WPA2?It is the second generation of WPA. WPA2 is based on the final IEEE 802.11i amendment to the802.11 standard.
-58-5.17 What is 802.1x Authentication?802.1x is a framework for authenticated MAC-level access control, defines Extensible AuthenticationProtocol (EAP) over LANs (WAPOL). The standard encapsulates and leverages much of EAP, whichwas defined for dial-up authentication with Point-to-Point Protocol in RFC 2284.Beyond encapsulating EAP packets, the 802.1x standard also defines EAPOL messages thatconvey the shared key information critical for wireless security.5.18 What is Temporal Key Integrity Protocol (TKIP)?The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the IEEE 802.11i encryptionstandard 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 messageintegrity check and a re-keying mechanism, thus fixing the flaws of WEP.5.19 What is 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.5.20 What is Inter-Access Point Protocol (IAPP)?The IEEE 802.11f Inter-Access Point Protocol (IAPP) supports Access Point Vendor interoperability,enabling roaming of 802.11 Stations within IP subnet.IAPP defines messages and data to be exchanged between Access Points and between the IAPPand high layer management entities to support roaming. The IAPP protocol uses TCP for inter-Access Point communication and UDP for RADIUS request/response exchanges. It also uses Layer2 frames to update the forwarding tables of Layer 2 devices.5.21 What is Wireless Distribution System (WDS)?The Wireless Distribution System feature allows WLAN AP to talk directly to other APs via wirelesschannel, like the wireless bridge or repeater service.5.22 What is Universal Plug and Play (uPNP)?UPnP is an open networking architecture that consists of services, devices, and control points. Theultimate goal is to allow data communication among all UPnP devices regardless of media, operatingsystem, programming language, and wired/wireless connection.5.23 What is Maximum Transmission Unit (MTU) Size?Maximum Transmission Unit (MTU) indicates the network stack of any packet is larger than thisvalue will be fragmented before the transmission. During the PPP negotiation, the peer of the PPPconnection will indicate its MRU and will be accepted. The actual MTU of the PPP connection will beset to the smaller one of MTU and the peer’s MRU. The default is value 1400.
FREQUENTLY ASKED QUESTIONS (FAQ)-59-5.24 What is Clone MAC Address?Clone MAC address is designed for your special application that request the clients to register to aserver machine with one identified MAC address. Since that all the clients will communicate outsideworld through the WLAN Broadband Router, so have the cloned MAC address set on the WLANBroadband Router will solve the issue.5.25 What is DDNS?DDNS is the abbreviation of Dynamic Domain Name Server. It is designed for user own the DNSserver with dynamic WAN IP address.5.26 What is NTP Client?NTP client is designed for fetching the current timestamp from internet via Network Time protocol.User can specify time zone, NTP server IP address.5.27 What is VPN?VPN is the abbreviation of Virtual Private Network. It is designed for creating point-to point privatelink via shared or public network.5.28 What is IPSEC?IPSEC is the abbreviation of IP Security. It is used to transferring data securely under VPN.5.29 What is WLAN Block Relay Between Clients?An Infrastructure Basic Service Set is a BSS with a component called an Access Point (AP). Theaccess point provides a local relay function for the BSS. All stations in the BSS communicate withthe access point and no longer communicate directly. All frames are relayed between stations bythe access point. This local relay function effectively doubles the range of the IBSS.5.30 What is WMM?WMM is based on a subset of the IEEE 802.11e WLAN QoS draft standard. WMM adds prioritizedcapabilities to Wi-Fi networks and optimizes their performance when multiple concurringapplications, each with different latency and throughput requirements, compete for networkresources. By using WMM, end-user satisfaction is maintained in a wider variety of environmentsand traffic conditions. WMM makes it possible for home network users and enterprise networkmanagers to decide which data streams are most important and assign them a higher traffic priority.5.31 What is WLAN ACK TIMEOUT?ACK frame has to receive ACK timeout frame. If remote does not receive in specified period, it will beretransmitted.5.32 What is Modulation Coding Scheme (MCS)?MCS is Wireless link data rate for 802.11n. The throughput/range performance of a AP will dependon its implementation of coding schemes. MCS includes variables such as the number of spatialstreams, modulation, and the data rate on each stream. Radios establishing and maintaining a linkmust automatically negotiate the optimum MCS based on channel conditions and then continuouslyadjust the selection of MCS as conditions change due to interference, motion, fading, and other
-60-events.5.33 What is Frame Aggregation?Every 802.11 packet, no matter how small, has a fixed amount of overhead associated with it. FrameAggregation combines multiple smaller packets together to form one larger packet. The largerpacket can be sent without the overhead of the individual packets. This technique helps improve theefficiency of the 802.11n radio allowing more end user data to be sent in a given time. 5.34 What is Guard Intervals (GI)?A GI is a period of time between symbol transmission that allows reflections (from multipath) fromthe previous data transmission to settle before transmitting a new symbol. The 802.11n draftspecifies two guard intervals: 400ns (short) and 800ns (long). Support of the 400ns GI is optional fortransmit and receive.
