NAVIGATING THE WEB BROWSER INTERFACE19Advanced SettingsOperation Mode: This may be set to Access Point, Repeater or Ethernet Converter.These modes are described below:•Access Point – functions as a standard IEEE 802.11b access point•Repeater – repeats an access point’s signals to extend the acess points coverage•Ethernet Converter – provides a wireless connection to an access point via an RJ-45 connection to devices such as Microsoft Xbox and Ethernet ready embedded devices
SYSTEM CONFIGURATION20The parameters that follow may be configured in any of the three modes descibed above but the user is advised to leave them at their default settings.Transmission Rate: Set the data rate transmitted from the Wireless Access Point. The lower the data rate, the longer the transmission distance. (Default: Fully Automatic.)RTS Threshold: Set the RTS (Request to Send) frame length. You may configure the access point to initiate an RTS frame. If the packet size is smaller than the preset RTS threshold size, the RTS/CTS mechanism will NOT be enabledThe access point sends Request to Send (RTS) frames to a particular receiving station to negotiate the sending of a data frame. After receiving an RTS, the station sends a CTS (Clear to Send) frame to acknowledge the right of the sending station to send data frames. The access points contending for the medium may not be aware of each other. The RTS/CTS mechanism can solve this “Hidden Node Problem.” (Default: 2347)Fragmentation Threshold: The Fragmentation Threshold can be set between 256 and 2,346. If the packet size is smaller than the preset Fragment size, the packet will not be segmented.Fragmentation of the PDUs (Package Data Unit) can increase the reliability of transmissions because it increases the probability of a successful transmission due to smaller frame size. If there is significant interference present, or collisions due to high network utilization, try setting the fragment size to send smaller fragments. This will enable the retransmission of smaller frames much faster. However, it is more efficient to set the fragment size larger if very little or no interference is present because it requires overhead to send multiple frames. (Default: 2346)
NAVIGATING THE WEB BROWSER INTERFACE21Basic Rate: The highest rate specified is the rate the Wireless Access Point will use when transmitting broadcast/multicast and management frames. (Default: 1, 2 Mbps.)Preamble Type: The access points and client card drivers have a radio setting for RF Preamble. Enabling it can boost your throughput. Preamble Type offers a drop-down list with two options: Long or Short. If you are not sure whether all the clients and access point radios in your wireless network support the Short RF preamble, then leave this setting on Long (default).Transmit Power: Set the signal strength transmitted from the access point. The longer the transmission distance, the higher the transmission power required. (Default: Super)Selections - Weak, Medium, Normal, High and Super
SYSTEM CONFIGURATION22FilterThe MAC Filtering feature of the SMC2671W allows you to control access to your network clients based on the MAC (Media Access Control) Address of the client machine. This ID is unique to each network adapter. If the MAC address is listed in the table, that client machine will not have access to the network.

35NETWORK CONFIGURATIONAND PLANNINGThe Wireless Solution supports a stand-alone wireless network configuration, as well as an integrated configuration with 10 Mbps Ethernet LANs. For a list of the maximum distances between the AP/Bridge and wireless clients, refer to page 40.The wireless network cards and adapters can be configured as:•Ad hoc – for small departmental or SOHO LANs•Infrastructure – for enterprise LANsNetwork TopologiesAd Hoc Wireless LANAn ad hoc wireless LAN consists of a group of computers, each equipped with a wireless adapter or Ethernet converter, connected via radio signals as an independent wireless LAN. Computers in a specific ad hoc wireless LAN must be configured to the same radio channel.An ad hoc wireless LAN can be used for a small branch office or SOHO operation.Ad Hoc Wireless LANNotebook withWireless USB AdapterNotebook withWireless PC CardSMC2671 in EthernetConverter Mode
NETWORK CONFIGURATION AND PLANNING36Infrastructure Wireless LANAn integrated wired and wireless LAN is called an Infrastructure configuration. A Basic Service Set (BSS) consists of a group of wireless PC users, and an access point that is directly connected to the wired LAN. Each wireless PC in this BSS can talk to any computer in its wireless group via a radio link, or access other computers or network resources in the wired LAN infrastructure via the access point.The infrastructure configuration permits wireless clients to access the wired LAN and also increases the effective wireless transmission range for wireless clients as their signal can be passed through multiple access points.A wireless infrastructure can be used for access to a central database, or for connection between mobile workers, as shown in the following figure.FileServerSwitchDesktop PCWired LAN Extensionto Wireless AdaptersNotebook with WirelessPC Card AdapterPC with WirelessPCI AdapterSMC2671W inAccess Point Mode
NETWORK TOPOLOGIES37Infrastructure Wireless LAN for Roaming Wireless PCsThe Basic Service Set (BSS) is the communications domain for each wireless access point. For wireless PCs that do not need to support roaming, set the domain identifier (SSID) of the wireless card to the SS ID of the access point to which you want to connect. Check with your administrator for the SS ID of the access point to which he wants you to connect.A wireless infrastructure can also support roaming for mobile workers. More than one access point can be configured to create an Extended Service Set (ESS). By placing the Access Points so that a continuous coverage area is created, wireless users within this ESS can roam freely. All wireless network cards, adapters, and the wireles access point within a specific ESS must be configured with the same SSID.Note: If Access Point 2 is replaces by an SMC2671W set to Repeater mode then the SMC2761W will not establish its own BSS, but will repeat data messeges between Acess Point 1 and end users, thus extending the coverage area of Access Point 1.FileServerSwitchDesktop PC<BSS2>Seamless Roaming<ESS>Switch<BSS1>Notebook with WirelessPC Card AdapterAccess Point 1PC with WirelessPCI AdapterAccess Point 2Notebook with WirelessPC Card Adapter

43TERMINOLOGYThe following is a list of terminology that is used in this document.Access Point – An internetworking device that seamlessly connects wired and wireless networks.Ad Hoc – An ad hoc wireless LAN is a group of computers each with LAN adapters, connected as an independent wireless LAN.Backbone – The core infrastructure of a network. The portion of the network that transports information from one central location to another central location where it is unloaded onto a local system.Base Station – In mobile telecommunications, a base station is the central radio transmitter/receiver that maintains communications with the mobile radio telephone sets within its range. In cellular and personal communications applications, each cell or micro-cell has its own base station; each base station in turn is interconnected with other cells’ bases.BSS – BSS stands for “Basic Service Set.” It is an Access Point and all the LAN PCs that are associated with it.CSMA/CA – Carrier Sense Multiple Access with Collision Avoidance.ESS – ESS (ESS-ID, SSID) stands for “Extended Service Set.” More than one BSS is configured to become an Extended Service Set. LAN mobile users can roam between different BSSs in an ESS (ESS-ID, SSID).
TERMINOLOGY44Ethernet – A popular local area data communications network, which accepts transmission from computers and terminals. Ethernet operates on a 10 Mbps baseband transmission rate, using a shielded coaxial cable or shielded twisted pair telephone wire.Infrastructure – An integrated wireless and wired LAN is called an Infrastructure configuration.Fragmentation Threshold – In the 802.11 Standard, the MAC Layer may fragment and reassemble directed MSDUs or MMPDUs. The fragmentation and defragmentation mechanisms allow for fragment re-transmission.Preamble Type – Some access points and client card drivers have a radio setting for “Short” RF Preamble. If all the clients and access points in your wireless network have this feature, then enabling it can boost your throughput. However, if a radio does not support this feature, then it will not be able to communicate with any other radios that have this set to “Short.”Roaming – A wireless LAN mobile user moves around an ESS and maintains a continuous connection to the Infrastructure network.RTS Threshold – Transmitters contending for the medium may not be aware of each other. RTS/CTS mechanism can solve this “Hidden Node Problem.” If the packet size is smaller than the preset RTS Threshold size, the RTS/CTS mechanism will NOT be enabled.WEP – “Wired Equivalent Privacy” is based on the use of 64-bit or 128-bit keys and the popular RC4 encryption algorithm. Wireless devices without a valid WEP key will be excluded from network traffic.
