Computers in a specific Ad-Hoc wireless LAN must be configured at thesame radio channel and ESSID.Ad-Hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation.InfrastructureFig. 2 An Example of Infrastructure Wireless LANDesktop PCwithGL241101Desktop PCwithGL241101NotebookwithGL241101NotebookwithGL241101Ad HocWireless LANEthernetDesktop PC with ethernet Desktop PC with ethernet SeverGL2411AP-0A GL2411AP-0ANotebookwithGL241101NotebookwithGL241101NotebookwithGL241101Desktop PCwithGL241101Desktop PCwithGL241101Desktop PCwithGL241101InfrastructureWireless LAN InfrastructureWireless LAN
20GL2411AP-0A provides access to a wired LAN for wireless workstations. An integrated wireless andwired LAN is called an Infrastructure configuration. A group of LAN PC users and a GL2411AP-0AAccess Point construct a Basic Service Set (BSS). Each LAN PC in the BSS can talk to any computer inthe wired LAN infrastructure via the GL2411AP-0A Access Point.Infrastructure configuration not only extends the accessibility of a LAN PC to the wired LAN, but alsodoubles the effective wireless transmission range for 2 LAN PCs. Since GL2411AP-0A is able toforward data within its BSS, the effective transmission range in an infrastructure LAN is doubled.BSS ID is, in essence, the ID of each independent GL2411AP-0A. All LAN PCs configured withoutroaming options in the independent BSS must be configured with the BSS ID of the GL2411AP-0A.Infrastructure is applicable in an enterprise scale for wireless access to central databases, or wirelessaccess for mobile workers.A-2 RoamingFig. 3 Roaming in an Extended Service Set (ESS)An Infrastructure configuration also supports roaming capability for mobile workers. More than one BSScan be configured to be an Extended Service Set (ESS). On account of a continuous connection to thenetwork, users within an ESS can roam freely. All LAN PCs and GL2411AP-0As within one ESS must beconfigured with the same ESS ID and at the same radio channel.EthernetDesktop PC with ethernet Desktop PC with ethernet SeverGL2411AP-0A GL2411AP-0ANotebookwithGL241101NotebookwithGL241101NotebookwithGL241101Desktop PCwithGL241101BSS1 BSS2ESSNotebookwithGL241101Roaming

22Appendix C GlossaryAccess 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 anindependent wireless LAN.Backbone ― The core infrastructure of a network. The portion of the network transports information from onecentral location to another central location where it is unloaded onto a local system.Bridge ― An internetworking function that incorporates the lowest 2 layers of the OSI network protocol model.BSS ― BSS stands for “Basic Service Set”. It is an Access Point and all the LAN PCs that associated with it.ESS ― ESS stands for “Extended Service Set”. More than one BSS is configured to become Extended ServiceSet. LAN mobile users can roam between different BSSs in an ESS.Ethernet ― A popular local area data communications network, originally developed by Xerox Corp., thataccepts transmission from computers and terminals. Ethernet operates on a 10 Mbps baseband transmission rate,using a shielded coaxial cable or over shielded twisted pair telephone wire.Infrastructure ― An integrated wireless and wired LAN is called an Infrastructure configuration.Roaming ― A LAN mobile user moves around an ESS and enjoys a continuous connection to the Infrastructurenetwork.RTS Threshold ― Transmitters contending for the medium may not be aware of each other. RTS/CTSmechanism can solve this “ Hidden Node Problem”. If the packet size is smaller than the preset RTS Thresholdsize, the RTS/CTS mechanism will NOT be enabled.DSSS ― direct sequence spread spectrumPLCP ― physical layer convergence protocolPPDU ― PLCP protocol data unitPSDU ― PLCP service data unitEthernet Mac Address ― Don’t change it, as this will disable the AP.Ethernet IP Address and SubMask ― Please setup them to match your network environment.For example : If your IP address is 192.168.99.127 and your SubMask is 255.255.255.0. Please set theIP address of the AP to 192.168.99.xx which will not have conflict with other IP addressand set the SubMask of the AP to 255.255.255.0.Channel ― The AP and the with it associated stations will work in this channel. You must set the channel byconsulting Appendix B from violating the Specifications.Basic Rate ― the data rate of the AP with the value 1,2,5.5 or 11 Mbps for your selection.
23ESSID ― In infrastructure association , the stations will link to the AP with the same ESSID as they have.WEP ― Wired Equivalent Privacy (Wep) is an encryption scheme used to protect wireless data communication.To enable the icon will prevent other stations without the same WEP key from linking with the AP.Preamble Type ― During transmission, the PSDU shall be appended to a PLCP preamble and header to createthe PPDU. Two different preambles and headers are defined : the mandatory supported long preamble and headerwhich interoperates with the current 1 and 2 Mbit/s DSSS specification as described in IEEE Std 802.11-1999,and an optional short preamble and header. At the receiver, the PLCP preamble and header are processed to aid indemodulation and delivery of the PSDU. The optional short preamble and header is intended for applicationwhere maximum throughput is desired and interoperability with legacy and non short preamble capable equipmentis not consideration. That is, it is expected to be used only in networks of like equipment that can all handle theoptional mode. (IEEE 802.11b standard)Authentication Type ― Indication of an authentication algorithm which can be supported by this node:1. Open System : Open System authentication is the simplest of the available authentication algorithms.Essentially it is a null authentication algorithm. Any station that requests authentication with thisalgorithm may become authenticated if dot11AuthenticationType at the recipient station is set to OpenSystem authentication.2. Shared Key : Shared Key authentication supports authentication of STAs as either a member of thosewho know a shared secret key or a member of those who do not.Open System authentication is the default authentication algorithm.
