12 Wireless BasicsWireless products are based on industry standards to provideeasy-to-use and compatible high-speed wireless connectivity withinyour home or business. Strictly adhering to the 802.11b and 802.11gstandards, our wireless family of products will allow you to accessthe data you want, when and where you want it. No longer will yoube limited to one location or forced to run new wiring through yourhome or office. You will be able to enjoy the freedom that wirelessnetworking delivers.A wireless local area network (WLAN) is a cellular computernetwork that transmits and receives data with radio signals instead ofwires. Wireless LANs are used increasingly in both home and officeenvironments, and public areas such as airports, coffee shops anduniversities. Innovative ways to utilize WLAN technology are helpingpeople to work and communicate more efficiently. Increased mobilityand the absence of cabling and other fixed infrastructure haveproven to be beneficial for many users.Wireless users can use the same applications they use on awired network. Wireless adapter cards used on laptop and desktopsystems, support the same protocols as Ethernet adapter cards.Under many circumstances, it may be desirable for mobilenetwork devices to link to a conventional Ethernet LAN in order touse servers, printers or an Internet connection supplied through thewired LAN. A Wireless Access Point (AP) is a device used to providethis link.
2The advantages of Wireless LAN are many and varied andinclude:z Mobility − Productivity increases when people haveaccess to data in any location within the operating range ofthe WLAN. Management decisions based on real-timeinformation can significantly improve worker efficiency.z Low Implementation Costs – WLANs (Wireless LocalArea Networks) are easy to set up, manage, change andrelocate. Networks that frequently change, both physicallyand logically, can benefit from WLANs ease ofimplementation. WLANs can operate in locations whereinstallation of wiring may be impractical.z Installation Speed and Simplicity − Installing a wirelessLAN system can be fast and easy and can eliminate theneed to pull cable through walls and ceilings.z Network Expansion − Wireless technology allows thenetwork to go where wires cannot go.z Reduced Cost-of-Ownership − While the initialinvestment required for wireless LAN hardware might behigher than the cost of wired LAN hardware, overallinstallation expenses and life-cycle costs will besignificantly lower. Long-term cost benefits are greatest indynamic environments requiring frequent moves, adds,and changes.z Scalability − Wireless Local Area Networks (WLANs) canbe configured in a variety of topologies to meet the needsof specific applications and installations. Configurationsare easily changed and range from peer-to-peer networkssuitable for a small number of users to full infrastructure
3networks of thousands of users that allow roaming over abroad area.
13 ConfigurationInsert WCB-G03H into the slot of MT841, and then enter theweb-based configuration of MT841. The layout of MT841 configuringpage shown as below when you first log in.z The left part of the page is wizard column, and you canenter the web page of configuration or managementthrough the hyperlink in wizard column.z The right part of the page is the practical domain ofconfiguration and management.Figure 3-3 Layout of Web-based Configuratio n ManagerClick the WLAN of Basic in the Wizard Column to set theWLAN configuration.
2Figure 3-4 Wireless ConfigurationThe illustration of this page as below:z SSID: The SSID identifies members of Service Set. If theSSID is changed, all other devices on the wireless networkmust use the same SSID.z Channel: The available channel for the MT841 isdepending on the local regulatory environment. Rememberthat all devices communicating with the device must usethe same channel (and use the same SSID). Use the dropdown menu to select the channel used for your wirelessLAN.z Module: MT841 provides multiple wireless bands, selectthe suitable band from the drop-down menu.z WEP Method: WEP (Wireless encryption Protocol)encryption can be enabled for security and privacy. WEPencrypts the data portion of each frame transmitted from
3the wireless adapter using one of the predefined keys. Ifnetwork Security is not used, click None, otherwise selectWEP or WPA-PSK.z WEP Key: The MT841 offers 64, 128, or 256-bitencryption with four keys available, select anencryption level from the drop-down menu on the right,and then enter the proper-length key.z WPA-PSK: Wi-Fi Protected Access was designed toprovide improved data encryption, perceived as weakin WEP, and to provide user authentication, largelynonexistent in WEP. There are two kinds of arithmetic:TKIP (Temporal Key Integrity Protocol) and AES(Advanced Encryption Standard), select arithmeticfrom the drop-down menu on the right, and then enterthe proper-length key.z WLAN connections: Select enable option, then theWALN connection will be enabled with above settings,otherwise it will be disabled.z SSID Hidden: Select enable option, and then the SSID willbe hided and can not be viewed by WLAN clients. It is toenable or disable SSID Hidden.Click the <Apply> button to save the settings while finished themodification.
14 WEP GlossaryThe following WEP parameters are be defined:Wireless Band − Select the environment you are configuring.Authentication − Select different authentication levels tomanage the data transmission.Open System − Using an open system with WEP enabledmeans the access point and wireless stations encrypt only the datain each packet. WEP is not used for the purpose of authentication,that is, encryption does not prevent any station from associating withthe access point.Share Key − With this setting only stations using a shared keyencryption identified by the access point are allowed to associatewith it. Shared key WEP prohibits non-WEP WLAN stations fromassociating with the access point. Shared key WEP uses encryptionfor both data and authentication.802.1X − Authenticator − controls the physical access to thenetwork based on the authentication status of the client. Theauthenticator acts as an intermediary (proxy) between the client andthe authentication server, requesting identity information from theclient, verifying that information with the authentication server, andrelaying a response to the client.WPA − A new security feature, Wi-Fi Protected Accessauthorizes and identifies users based on a secret key that changesautomatically at a regular interval. WPA uses TKIP (Temporal Key
2Integrity Protocol) to change the temporal key every 10,000 packets(a packet is a kind of message transmitted over a network.) Thisinsures much greater security than the standard WEP security.WEP − Wired Equivalent Privacy. You can select to [Enable] or[Disable] WEP.WEP Key Type − Select HexValue, and use Key Table forHexValue to define a HexValue.WEP Key Size − 64-bit, 128-bit, 152-bit length WEP encryption.Valid Key − Provides 4 groups of options respectively.Key Table for HexValue − A HexValue is strictly definedaccording to the WEP encryption level (WEP Key Size). TheHexValue consists of the numbers from 0-9 and letters A-F. Eachencryption level requires a different number of HexValues digits asfollows:z 64-bit encryption, type in 10 hexadecimal digits in theQuickKey String fieldz 128-bit encryption, type in 26 hexadecimal digitsz 152-bit encryption, type in 58 hexadecimal digitsType in 4 hexadecimal values in the spaces provided. Use theValid Index drop-down menu to select the number of the HexValuekey (Group Index) to activate the key. Caution:If you have made encryption operation in [Open System], you will have to changethe password if you switch to [Share Key] mode. Otherwise the network adaptercannot access the AP.
