Chapter 2 Network Configuration and Planning 21Using the Nortel Networks Wireless LAN Access Point 2220/2221 Chapter 2Network Configuration and PlanningThe wireless solution supports a stand-alone wireless network configuration as well as an integrated configuration with 10/100 Mbps Ethernet LANs.The wireless network cards, adapters, access points and wireless access point can be configured as:• Ad hoc for departmental LANs• Infrastructure for wireless LANs• Infrastructure wireless LAN for roaming wireless PCsNetwork TopologiesAd Hoc Wireless LAN (no AP or Bridge)Ad-hoc mode is also called “peer-to-peer mode” or “Independent Basic Service Set (IBSS).” In ad hoc mode, devices communicate directly with each other without using an access point.An ad hoc wireless LAN consists of a group of computers, each equipped with a wireless adapter, connected via radio signals as an independent wireless LAN. Computers in a specific ad hoc wireless LAN must therefore be configured to the same radio channel. An ad hoc wireless LAN can be used for a branch office operation.Ad Hoc Wireless LANNotebook withWireless USB AdapterNotebook withWireless PC CardPC with WirelessPCI Adapter
22 Chapter 2 Network Configuration and Planning214853-B Infrastructure Wireless LANThe access point can also provide access to a wired LAN for wireless workstations. An integrated wired/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.Infrastructure 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) for the wireless card to the SSID of the access point to which you want to connect. Check with your administrator for the SSID of the access point or bridge to which he wants you to connect.FileServerSwitchDesktop PCAccess PointWired LAN Extensionto Wireless AdaptersPC with WirelessPCI AdapterNotebook with WirelessPC Card Adapter
Chapter 2 Network Configuration and Planning 23Using the Nortel Networks Wireless LAN Access Point 2220/2221 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 Nortel Networks Wireless LAN--Series 2200 wireless network cards and adapters and Access Point 2220/2221 wireless access points within a specific ESS must be configured with the same SSID.FileServerSwitchDesktop PCAccess Point<BSS2>Notebook with WirelessPC Card AdapterSeamless Roaming<ESS>SwitchAccess Point<BSS1>PC with WirelessPCI AdapterNotebook with WirelessPC Card Adapter

46 Chapter 3 System Configuration214853-B Radio ChannelThe radio channel (Figure 20) is the channel number used for communication between the access point and its BSS. (Default: channel 11) Maximum Station Data RateSelect the appropriate data rate from the drop-down list for the data transfer speed running on your network. (Default: 11 Mbps)Beacon Interval (20-1000)Sets the beacon signal interval. The beacon signals allow the wireless devices to maintain contact with each other. They may also carry power-management information. (Default: 100 TU)DTIM Period (1-16384)Sets the Delivery Traffic Indication Message (DTIM) packet interval value. The DTIM informs the client that the access point has broadcast and multicast traffic to send. This parameter is necessary to wake up stations that are using Power Save mode.Note: The available channel settings are limited by local regulations, which determine the number of channels that are available. (For more information specific to each country’s configuration, refer to Country-specific Configuration for the Nortel Networks Wireless LAN Access Point 2220/2221 (part number 215293-B).

Chapter 3 System Configuration 47Using the Nortel Networks Wireless LAN Access Point 2220/2221 The DTIM is the interval between two synchronous frames with broadcast information. If you set the value to 2, the access point saves broadcast and multicast packets and forwards them after every second beacon. Having smaller DTIM intervals delivers broadcast and multicast frames in a more timely manner; however, by causing stations in Power Save mode to wake up more often, smaller DTIM intervals drain power faster. Conversely, having higher DTIM values delays the transmission of broadcast and multicast frames, but the larger DTIM intervals reduces the power used by stations in Power Save mode. (Default: 5 Beacons)RTS Threshold (0-2347)Set the RTS (Request to Send) frame length. You may configure the access point to initiate an RTS frame sequence always, never, or only on frames longer than a specified length. If the packet size is smaller than the preset RTS threshold size, the RTS/CTS mechanism will NOT be enabledWhen the RTS/CTS mechanism is enabled, the 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 frame, 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 media may not be aware of each other. The RTS/CTS mechanism allows other access points in the vicinity to see the CTS and become quiet while the first access point transmits frames. (This mechanism should be enabled on both the clients and the access points.) (Default: 2347)Preamble SettingThe access points and client card drivers have a radio setting for RF Preamble. Set it to short for better throughput; although this setting may cause interoperability issues with some NICs. (Default: Long)
