IEEE 802.11 Shared Keyauthentication accomplishes this without the need to transmit thesecret key in clear. Requiring the use of the WEP privacy mechanism.
ViewSonic 3-in-1 Access Point 28• Transmission Rate: The rate of data transmission should be setdepending on the speed of your wireless network. You can select from arange of transmission speeds, or you can select AUTO to have the APautomatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possibleconnection speed between the AP and a wireless client. The defaultsetting is AUTO.• Beacon Interval: The Beacon Interval value indicates the frequencyinterval of the beacon. Enter a value between 20 and 1000. A beacon isa packet broadcast by the AP to synchronize the wireless network. Thedefault value is 100. • RTS Threshold: This value should remain at its default setting of 2346.Should you encounter inconsistent data flow, only minor modificationsare recommended.If a network packet is smaller than the preset RTS threshold size, theRTS/CTS mechanism will not be enabled. The AP sends Request toSend (RTS) frames to a particular receiving station and negotiates thesending of a data frame. After receiving an RTS, the wireless stationresponds with a Clear to Send (CTS) frame to acknowledge the right tobegin transmission. • Fragmentation Threshold: This value specifies the maximum size for apacket before data is fragmented into multiple packets. It should remainat its default setting of 2346. If you experience a high packet error rate,you may slightly increase the Fragmentation Threshold. Setting theFragmentation Threshold too low may result in poor networkperformance. Only minor modifications of this value are recommended. • DTIM Interval: This value indicates the interval of the Delivery TrafficIndication Message (DTIM). A DTIM field is a countdown field informingclients of the next window for listening to broadcast and multicastmessages. When the Access Point has buffered broadcast or multicastmessages for associated clients, it sends the next DTIM with a DTIMInterval value. Access Point Clients hear the beacons and awaken to receive thebroadcast and multicast messages. •Click Apply to save your settings.

ViewSonic 3-in-1 Access Point 34Wireless Security & Glossary10BaseT. An IEEE standard (802.3) for operating 10 Mbps Ethernetnetworks (LANs) with twisted pair cabling and a wiring hub.802.11 standard. 802.11 or IEEE 802.11 is a type of radio technology usedfor wireless local area networks (WLANs). It is a standard that has beendeveloped by the IEEE (Institute of Electrical and Electronic Engineers),http://standards.ieee.org. The IEEE is an international organization thatdevelops standards for hundreds of electronic and electrical technologies.The organization uses a series of numbers, like the Dewey Decimal systemin libraries, to differentiate between the various technology families. The 802subgroup (of the IEEE) develops standards for local and wide area networkswith the 802.11 section reviewing and creating standards for wireless localarea networks. Wi-Fi, 802.11 is composed of several standards operating indifferent radio frequencies: 802.11b is a standard for wireless LANsoperating in the 2.4 GHz spectrum with a bandwidth of 11 Mbps;802.11a is adifferent standard for wireless LANs, and pertains to systems operating inthe 5 GHz frequency range with a bandwidth of 54 Mbps. Another standard,802.11g, is for WLANS operating in the 2.4 GHz frequency but with abandwidth of 54 Mbps.802.11a. An IEEE specification for wireless networking that operates in the5 GHz frequency range (5.725 GHz to 5.850 GHz) with a maximum 54Mbps data transfer rate. The 5 GHz frequency band is not as crowded asthe 2.4 GHz frequency, because the 802.11a specification offers more radiochannels than the 802.11b.These additional channels can help avoid radioand microwave interference.802.11b. International standard for wireless networking that operates in the2.4 GHz frequency range (2.4 GHz to 2.4835 GHz) and provides athroughput of up to 11 Mbps. This is a very commonly used frequency.Microwave ovens, cordless phones, medical and scientific equipment, aswell as Bluetooth devices, all work within the 2.4 GHz frequency band.802.11g. Similar to 802.11b, but this standard provides a throughput of up to54 Mbps. It also operates in the 2.4 GHz frequency band but uses a differentradio technology in order to boost overall bandwidth.Access point. A wireless LAN transceiver or "base station" that canconnect a wired LAN to one or many wireless devices. Access points canalso bridge to each other. There are various types of access points andbase stations used in both wireless and wired networks. These includebridges, hubs, switches, routers and gateways. The differences between
ViewSonic 3-in-1 Access Point 35them are not always precise, because certain capabilities associated withone can also be added to another. For example, a router can do bridging,and a hub may also be a switch. But they are all involved in making suredata is transferred from one location to another. A bridge connects devicesthat all use the same kind of protocol. A router can connect networks thatuse differing protocols. It also reads the addresses included in the packetsand routes them to the appropriate computer station, working with any otherrouters in the network to choose the best path to send the packets on. Awireless hub or access point adds a few capabilities such as roaming andprovides a network connection to a variety of clients, but it does not allocatebandwidth. A switch is a hub that has extra intelligence: It can read theaddress of a packet and send it to the appropriate computer station. Awireless gateway is an access point that provides additional capabilitiessuch as NAT routing, DHCP, firewalls, security, etc.Ad-Hoc mode. A client setting that provides independent peer-to peerconnectivity in a wireless LAN. An alternative set-up is one where PCscommunicate with each other through an AP.Applet. An application or utility program that is designed to do a veryspecific and limited task.Backbone. The central part of a large network that links two or more subnetworks and is the primary path for data transmission for a large business orcorporation. A network can have a wired backbone or a wireless backbone.Bandwidth. The amount of transmission capacity that is available on anetwork at any point in time. Available bandwidth depends on severalvariables such as the rate of data transmission speed between networkeddevices, network overhead, number of users, and the type of device used toconnect PCs to a network. It is similar to a pipeline in that capacity isdetermined by size: the wider the pipe, the more water can flow through it;the more bandwidth a network provides, the more data can flow through it.Standard 802.11b provides a bandwidth of 11 Mbps; 802.11a and 802.11gprovide a bandwidth of 54 Mbps.Bits per second (bps). A measure of data transmission speed overcommunication lines based on the number of bits that can be sent orreceived per second. Bits per second-bps-is often confused with bytes persecond-Bps. While "bits" is a measure of transmission speed, "bytes" is ameasure of storage capability. 8bits make a byte, so if a wireless network isoperating at a bandwidth of 11 megabits per second (11 Mbps or 11 Mbits/sec.), it is sending data at 1.375 megabytes per second (1.375 MBps).
ViewSonic 3-in-1 Access Point 36Bluetooth wireless technology. A technology specification for linkingportable computers, personal digital assistants (PDAs) and mobile phonesfor short-range transmission of voice and data across a global radiofrequency band without the need for cables or wires. Bluetooth is afrequency-hopping technology in the 2.4 GHz frequency spectrum, with arange of 30 feet.Bridge. A product that connects a local area network (LAN) to another localarea network that uses the same protocol (for example, wireless, Ethernetor token ring). Wireless bridges are commonly used to link buildings incampuses.Broadband. A comparatively fast Internet connection. Services such asISDN, cable modem, DSL and satellite are all considered broadband ascompared to dial-up Internet access. There is no official speed definition ofbroadband but services of 100Kbps and above are commonly thought of asbroadband.Bus adapter. A special adapter card that installs in a PC's PCI or ISA slotand enables the use of PC Card radios in desktop computers. Somecompanies offer one-piece PCI or ISA Card radios that install directly into anopen PC or ISA slot.Cable modem. A kind of converter used to connect a computer to a cableTV service that provides Internet access. Most cable modems have anEthernet out-cable that then attaches to the user's Wi-Fi gateway.Client. Any computer connected to a network that requests services (files,print capability) from another member of the network.Client devices. Clients are end users. Wi-Fi client devices include PCCards that slide into laptop computers, mini-PCI modules embedded inlaptop computers and mobile computing devices, as well as USB radios andPCI/ISA bus Wi-Fi radios. Client devices usually communicate with hubdevices like access points and gateways.Collision avoidance. A network node characteristic for operativelydetecting that it can transmit a signal without risking a collision.Crossover cable. A special cable used for networking two computerswithout the use of a hub. Crossover cables may also be required forconnecting a cable or DSL modem to a wireless gateway or access point.Instead of the signals transferring in parallel paths from one set of plugs toanother, the signals "cross-over." If an eight-wire cable was being used, forinstance, the signal would start on pin one at one end of the cable and end
ViewSonic 3-in-1 Access Point 37up on pin eight at the other end. They "cross-over" from one side to theother.CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance).The principle medium access method employed by IEEE 802.11 WLANs. Itis a "listen before talk": method of minimizing (but not eliminating) collisionscaused by simultaneous transmission by multiple radios. IEEE 802.11 statescollision avoidance method rather than collision detection must be used,because the standard employs half duplex radios-radios capable oftransmission or reception-but not both simultaneously. Unlike conventionalwired Ethernet nodes, a WLAN station cannot detect a collision whiletransmitting. If a collision occurs, the transmitting station will not receive anACK knowledge packet from the intended receive station. For this reason,ACK packets have a higher priority than all other network traffic. Aftercompletion of a data transmission, the receive station will begintransmission of the ACK packet before any other node can begintransmitting a new data packet. All other stations must wait a longer pseudorandomized period of time before transmitting. If an ACK packet is notreceived, the transmitting station will wait for a subsequent opportunity toretry transmission.CSMA/CD (Carrier Sense Multiple Access/Collision Detection). Amethod of managing traffic and reducing noise on an Ethernet network. Anetwork device transmits data after detecting that a channel is available.However, if two devices transmit data simultaneously, the sending devicesdetect a collision and retransmit after a random time delay.DC power module. Modules that convert AC power to DC. Depending onmanufacturer and product, these modules can range from typical "wall wart"transformers that plug into a wall socket and provide DC power via a tinyplug to larger, enterprise-level Power Over Ethernet systems that inject DCpower into the Ethernet cables connecting access points.DHCP (Dynamic Host Configuration Protocol). A utility that enables aserver to dynamically assign IP addresses from a predefined list and limittheir time of use so that they can be reassigned. Without DHCP, an ITManager would have to manually enter in all the IP addresses of all thecomputers on the network. When DHCP is used, whenever a computer logsonto the network, it automatically gets an IP address assigned to it.Dial-up. A communication connection via the standard telephone network,or Plain Old Telephone Service (POTS).
ViewSonic 3-in-1 Access Point 38Diversity antenna. A type of antenna system that uses two antennas tomaximize reception and transmission quality and reduce interference.DNS (Domain Name System, or Service, or Server). A program thattranslates URLs to IP addresses by accessing a database maintained on acollection of Internet servers. The program works behind the scenes tofacilitate surfing the Web with alpha versus numeric addresses. A DNSserver converts a name like mywebsite.com to a series of numbers like107.22.55.26. Every website has its own specific IP address on the Internet.DSL (Digital Subscriber Lines). Various technology protocols for high-speed data, voice and video transmission over ordinary twisted-pair copperPOTS (Plain Old Telephone Service) telephone wires.Encryption key. An alphanumeric (letters and/or numbers) series thatenables data to be encrypted and then decrypted so it can be safely sharedamong members of a network. WEP uses an encryption key thatautomatically encrypts outgoing wireless data. On the receiving side, thesame encryption key enables the computer to automatically decrypt theinformation so it can be read.ESSID (Extended Service Set ID). The identifying name of an 802.11wireless network. When you specify your correct ESSID in your client setupyou ensure that you connect to your wireless network rather than anothernetwork in range. (See SSID.) The ESSID can be called by different terms,such as Network Name, Preferred Network, SSID or Wireless LAN ServiceArea.Ethernet. International standard networking technology for wiredimplementations. Basic 10BaseT networks offer a bandwidth of about 10Mbps. Fast Ethernet (100 Mbps) and Gigabit Ethernet (1000 Mbps) arebecoming popular.Firewall. A system that secures a network and prevents access byunauthorized users. Firewalls can be software, hardware or a combinationof both. Firewalls can prevent unrestricted access into a network, as well asrestrict data from flowing out of a network.Gateway. In the wireless world, a gateway is an access point with additionalsoftware capabilities such as providing NAT and DHCP. Gateways may alsoprovide VPN support, roaming, firewalls, various levels of security, etc.Hotspot. A place where you can access Wi-Fi service. This can be for freeor for a fee. HotSpots can be inside a coffee shop, airport lounge, trainstation, convention center, hotel or any other public meeting area.
ViewSonic 3-in-1 Access Point 39Corporations and campuses are also implementing Hotspots to providewireless Internet access to their visitors and guests. In some parts of theworld, HotSpots are known as Cool Spots.Hub. A multipart device used to connect PCs to a network via Ethernetcabling or via WiFi. Wired hubs can have numerous ports and can transmitdata at speeds ranging from 10 Mbps to multi-gigabyte speeds per second.A hub transmits packets it receives to all the connected ports. A small wiredhub may only connect four computers; a large hub can connect 48 or more.Wireless hubs can connect hundreds.HZ (Hertz). The international unit for measuring frequency, equivalent to theolder unit of cycles per second. One megahertz (MHz) is one million hertz.One gigahertz (GHz) is one billion hertz.

New York,www.ieee.org. A membership organization that includes engineers,scientists and students in electronics and allied fields. It has more than300,000 members and is involved with setting standards for computers andcommunications.IEEE802.11. A set of specifications for LANs from The Institute of Electricaland Electronics Engineers (IEEE). Most wired networks conform to 802.3,the specification for CSMA/CD based Ethernet networks or 802.5, thespecification for token ring networks. 802.11 defines the standard forwireless LANs encompassing three incompatible (non-interoperable)technologies: Frequency Hopping Spread Spectrum (FHSS), DirectSequence Spread Spectrum (DSSS) and Infrared. WECA's focus is on802.11b, an 11 Mbps high-rate DSSS standard for wireless networks.Infrastructure mode. A client setting providing connectivity to an AP. Ascompared to Ad-Hoc mode, whereby PCs communicate directly with eachother, clients set in Infrastructure Mode all pass data through a central AP.The AP not only mediates wireless network traffic in the immediateneighborhood, but also provides communication with the wired network.See Ad-Hoc and AP.Internet appliance. A computer that is intended primarily for Internetaccess, is simple to set up and usually does not support installation of third-party software. These computers generally offer customized web browsing,touch-screen navigation, e-mail services, entertainment and personal
ViewSonic 3-in-1 Access Point 40information management applications. An Internet appliance can be Wi-Fienabled or it can be connected via a cable to the local network.IP (telephony). Technology that supports voice, data and videotransmission via IP-based LANs, WANs, and the Internet. This includesVoIP (Voice over IP).IP address. A 32-bit number that identifies each sender or receiver ofinformation that is sent across the Internet. An IP address has two parts: anidentifier of a particular network on the Internet and an identifier of theparticular device (which can be a server or a workstation) within thatnetwork.IPX-SPX (Internet work Packet Exchange-Sequenced PacketExchange). IPX is a networking protocol used by the Novell NetWareoperating systems. Like UDP/IP, IPX is a datagram protocol used forconnectionless communications. Higher-level protocols, such as SPX andNCP, are used for additional error recovery services. SPX is a transportlayer protocol (layer 4 of the OSI Model) used in Novell Netware networks.The SPX layer sits on top of the IPX layer (layer 3) and provides connection-oriented services between two nodes on the network. SPX is used primarilyby client/server applications. Whereas the IPX protocol is similar to IP, SPXis similar to TCP. Together, therefore, IPX-SPX provides connection servicessimilar to TCP/IP.ISA (Industry Standard Architecture). A type of internal computer bus thatallows the addition of card-based components like modems and networkadapters. ISA has been replaced by PCI and is not very common anymore.ISO Network Model (International Standards Organization). A networkmodel developed by the ISO that consists of seven different levels, orlayers. By standardizing these layers, and the interfaces in between,different portions of a given protocol can be modified or changed astechnologies advance or systems requirements are altered. The sevenlayers are:•Physical•Data Link•Network•Transport•Session•Presentation•Application
ViewSonic 3-in-1 Access Point 41The IEEE 802.11 Standard encompasses the physical layer (PHY) and thelower portion of the data link layer. The lower portion of the data link layer isoften referred to as the Medium Access Controller (MAC) sub layer.ISS (Internet Security Services). A special software application that allowsall PCs on a network access to the Internet simultaneously through a singleconnection and Internet Service Provider (ISP) account.LAN (Local Area Network). A system of connecting PCs and other deviceswithin the same physical proximity for sharing resources such as an Internetconnections, printers, files and drives. When Wi-Fi is used to connect thedevices, the system is known as a wireless LAN or WLAN.MAC (Medium Access Controller). Every wireless 802.11 device has itsown specific MAC address hard-coded into it. This unique identifier can beused to provide security for wireless networks. When a network uses a MACtable, only the 802.11 radios that have had their MAC addresses added tothat network's MAC table will be able to get onto the network.Mapping. Assigning a PC to a shared drive or printer port on a network.NAT (Network Address Translation). A network capability that enables ahouseful of computers to dynamically share a single incoming IP addressfrom a dial-up, cable or xDSL connection. NAT takes the single incoming IPaddress and creates new IP address for each client computer on thenetwork. NAT provides a type of firewall by hiding internal IP addresses.Network name. Identifies the wireless network for all the sharedcomponents. During the installation process for most wireless networks, youneed to enter the network name or SSID. Different network names are usedwhen setting up your individual computer, wired network or workgroup.NIC (Network Interface Card). An expansion board you insert into acomputer so the computer can be connected to a network. A NIC is a type ofPC adapter card that either works without wires (Wi-Fi) or attaches to anetwork cable to provide two-way communication between the computerand network devices such as a hub or switch. Most office wired NICsoperate at 10 Mbps (Ethernet), 100 Mbps (Fast Ethernet) or 10/100 Mbpsdual speed. High-speed Gigabit and 10 Gigabit NIC cards are alsoavailable. See PC Card.PC Card. A removable, credit-card-sized memory or I/O device that fits intoa Type 2 PCMCIA standard slot, PC Cards are used primarily in PCs,portable computers, PDAs and laptops. PC Card peripherals include Wi-Ficards, memory cards, modems, NICs, hard drives, etc.
ViewSonic 3-in-1 Access Point 42PCI (Peripheral Component Interconnect). A high-performance I/Ocomputer bus used internally on most computers. Other bus types includeISA and AGP. PCIs and other computer buses enable the addition ofinternal cards that provide services and features not supported by themotherboard or other connectors.PCMCIA (Personal Computer Memory Card International Association).Expansion cards now referred to as "PC Cards" were originally called"PCMCIA Cards" because they met the standards created by the PCMCIA.Peer-to-peer network. A wireless or wired computer network that has noserver or central hub or router. All the networked PCs are equally able to actas a network server or client, and each client computer can talk to all theother wireless computers without having to go through an access point orhub. However, since there is no central base station to monitor traffic orprovide Internet access, the various signals can collide with each other,reducing overall performance.PHY (Physical Layer). The lowest layer within the OSI Network Model. Itdeals primarily with transmission of the raw bit stream over the Physicaltransport medium. In the case of wireless LANs, the transport medium isfree space. The PHY defines parameters such as data rates, modulationmethod, signaling parameters, transmitter/receiver synchronization, etc.Within an actual radio implementation, the PHY corresponds to the radiofront end and base band signal processing sections.Proxy server. Used in larger companies and organizations to improvenetwork operations and security, a proxy server is able to prevent directcommunication between two or more networks. The proxy server forwardsallowable data requests to remote servers and/or responds to data requestsdirectly from stored remote server data.Range. How far will your wireless network stretch? Most Wi-Fi systems willprovide a range of a hundred feet or more. Depending on the environmentand the type of antenna used, Wi-Fi signals can have a range of up to mile.Residential gateway. A wireless device that connects multiple PCs,peripherals and the Internet on a home network. Most Wi-Fi residentialgateways provide DHCP and NAT as well.RJ-45. Standard connectors used in Ethernet networks. Even though theylook very similar to standard RJ-11 telephone connectors, RJ-45 connectorscan have up to eight wires, whereas telephone connectors have only four.
ViewSonic 3-in-1 Access Point 43Roaming. Moving seamlessly from one AP coverage area to another withno loss in connectivity.Router. A device that forwards data packets from one local area network(LAN) or wide area network (WAN) to another. Based on routing tables androuting protocols, routers can read the network address in each transmittedframe and make a decision on how to send it via the most efficient routebased on traffic load, line costs, speed, bad connections, etc.Server. A computer that provides its resources to other computers anddevices on a network. These include print servers, Internet servers and dataservers. A server can also be combined with a hub or router.SSID (Service Set Identifier). A 32-character unique identifier attached tothe header of packets sent over a WLAN that acts as a password when amobile device tries to connect to the BSS. (Also called ESSID.) The SSIDdifferentiates one WLAN from another, so all access points and all devicesattempting to connect to a specific WLAN must use the same SSID. Adevice will not be permitted to join the BSS unless it can provide the uniqueSSID. Because an SSID can be sniffed in plain text from a packet, it doesnot supply any security to the network. An SSID is also referred to as aNetwork Name because essentially it is a name that identifies a wirelessnetwork.SSL (Secure Sockets Layer). Commonly used encryption scheme used bymany online retail and banking sites to protect the financial integrity oftransactions. When an SSL session begins, the server sends its public keyto the browser. The browser then sends a randomly generated secret keyback to the server in order to have a secret key exchange for that session.Sub network or Subnet. Found in larger networks, these smaller networksare used to simplify addressing between numerous computers. Subnetsconnect to the central network through a router, hub or gateway. Eachindividual wireless LAN will probably use the same subnet for all the localcomputers it talks to.Switch. A type of hub that efficiently controls the way multiple devices usethe same network so that each can operate at optimal performance. Aswitch acts as a networks traffic cop: rather than transmitting all the packetsit receives to all ports as a hub does, a switch transmits packets to only thereceiving port.TCP (Transmission Control Protocol). A protocol used along with theInternet Protocol (IP) to send data in the form of individual units (calledpackets) between computers over the Internet. While IP takes care of
ViewSonic 3-in-1 Access Point 44handling the actual delivery of the data, TCP takes care of keeping track ofthe packets that a message is divided into for efficient routing through theInternet. For example, when a web page is downloaded from a web server,the TCP program layer in that server divides the file into packets, numbersthe packets, and then forwards them individually to the IP program layer.Although each packet has the same destination IP address, it may getrouted differently through the network. At the other end, TCP reassemblesthe individual packets and waits until they have all arrived to forward themas a single file.TCP/IP (Transmission Control Protocol/Internet Protocol).Theunderlying technology behind the Internet and communications betweencomputers in a network. The first part, TCP, is the transport part, whichmatches the size of the messages on either end and guarantees that thecorrect message has been received. The IP part is the user's computeraddress on a network. Every computer in a TCP/IP network has its own IPaddress that is either dynamically assigned at startup or permanentlyassigned. All TCP/IP messages contain the address of the destinationnetwork as well as the address of the destination station. This enables TCP/IP messages to be transmitted to multiple networks (subnets) within anorganization or worldwide.UPnP. A networking architecture that provides compatibility amongnetworking equipment, software and peripherals of the 400+ vendors thatare part of the Universal Plug and Play Forum. UPnP works with wired orwireless networks and can be supported on any operating system. UPnPboasts device-driver independence and zero-configuration networking.USB (Universal Serial Bus). A high-speed bidirectional serial connectionbetween a PC and a peripheral that transmits data at the rate of 12megabits per second. The new USB 2.0 specification provides a data rate ofup to 480 Mbps, compared to standard USB at only 12 Mbps. 1394,FireWire and iLink all provide a bandwidth of up to 400 Mbps.VoIP (Voice Over Internet Protocol). Voice transmission using InternetProtocol to create digital packets distributed over the Internet. VoIP can beless expensive than voice transmission using standard analog packets overPOTS (Plain Old Telephone Service).VPN (Virtual Private Network). A type of technology designed to increasethe security of information transferred over the Internet. VPN can work witheither wired or wireless networks, as well as with dial-up connections overPOTS. VPN creates a private encrypted tunnel from the end user's
ViewSonic 3-in-1 Access Point 45computer, through the local wireless network, through the Internet, all theway to the corporate servers and database.WAN (Wireless Area Network). A communication system of connectingPCs and other computing devices across a large local, regional, national orinternational geographic area. Also used to distinguish between phone-based data networks and Wi-Fi. Phone networks are considered WANs andWi-Fi networks are considered Wireless Local Area Networks (WLANs).WEP (Wired Equivalent Privacy). Basic wireless security provided by Wi-Fi. In some instances, WEP may be all a home or small business userneeds to protect wireless data. WEP is available in 40-bit (also called 64-bit), or in 108-bit (also called 128-bit) encryption modes. As 108-bitencryption provides a longer algorithm that takes longer to decode, it canprovide better security than basic 40-bit (64-bit) encryption.Wi-Fi (Wireless Fidelity). An inter-operability certification for wireless localarea network (LAN) products based on the Institute of Electrical andElectronics Engineers (IEEE) 802.11 standard.WLAN (Wireless Local Area Network). Also referred to as LAN. A type oflocal-area network that uses high-frequency radio waves rather than wiresto communicate between nodes.WPA-Enterprise (Wi-Fi Protected AccessTM - Enterprise). It is Wi-Fi'sencryption method that protects unauthorized network access by verifyingnetwork users through a server. WPA-Personal (Wi-Fi Protected AccessTM - Personal). It is Wi-Fi'sencryption method that protects unauthorized network access by using aset-up password.
