Quick Installation Guide31Infrastructure Wireless LANThe WN3501C can also provide access to a wired LAN for wireless workstations. An 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 not only extends the accessibility of wireless PCs to the wired LAN, but also increases the effective wireless transmission range for wireless PCs by passing their signal through one or more 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.Setting the Communication DomainStationary Wireless PCsThe Basic Service Set (BSS) is the communication domain for each access point. For wireless PCs that do not need to support roaming, set the domain identifier (SSID) for the wireless adapter to the BSS ID of the access point to which you want to connect. Check with your administrator for the BSS ID of the access point to which he wants you to connect.Roaming Wireless PCsA infrastructure network also supports roaming for mobile workers. More than one access point may be configured with the same SSID 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.

11 Mbps Wireless USB Adapter38 TerminologyThe following is a list of terminology 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.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.Data Frame – Packets transmitted/received by the device that carry data (see Management Frame on the next page.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).Ethernet – A popular local area data communications network, which accepts transmissions from computers and terminals. Ethernet operates on a 10 Mbps baseband transmission rate, using shielded coaxial cable or twisted-pair cable.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”.Infrastructure – An integrated wireless and wired LAN is called an Infrastructure configuration.Management Frame – Control frame for establishing a link between an access point and a client station. It includes Beacon, Probe, Authentication, and Association frames.MSDUs – MAC Service Data Units.MMPDUs – MAC Management Protocol Data Units.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
Quick Installation Guide39other. 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.USB – The Universal Serial Bus allows complete Plug and Play connection of peripheral devices to a computer.WEP – “Wired Equivalent Privacy” is based on the use of keys and the popular RC4 encryption algorithm. Wireless devices without a valid WEP key are excluded from network traffic.
