Introduction The Nortel Networks Wireless LAN Access Point 2220 (Access Point 2220) is an access point that provides transparent, wireless high-speed data communications between the wired LAN and fixed, portable or mobile devices equipped with an 802.11a/802.11b (or A only card or B only card) wireless adapter employing the same radio modulation. This solution offers fast, reliable wireless connectivity with considerable cost savings over wired LANs (which include long-term maintenance overhead for cabling). Using 802.11a,11b technology, the Access Point 2220 can easily replace a 10 Mbps Ethernet connection or seamlessly integrate into a 10/100 Ethernet LAN. Package Checklist The Access Point 2220 package includes: • • • One Access Point 2220 Driver & Utility CD Documentation CD Hardware Description Ethernet Compatibility The Access Point 2220 can attach directly to 10BASE-T/100BASE-TX (twisted-pair) Ethernet LAN segments. These segments must conform to the IEEE 802.3 specification. Using the Nortel Networks Wireless LAN Access Point 2220 AccessPointUG.book Page 14 Thursday, February 27, 2003 12:22 PM [Final Draft—Nortel Confidential] 14 Preface The access point appears as an Ethernet node and performs a routing function by moving packets from the wired LAN to remote workstations on the wireless infrastructure. Radio Characteristics For the A radio, the Access Point 2220 uses a radio modulation technique known as Orthogonal Frequency Division Multiplexing (OFDM), and a shared collision domain (CSMA/CA). It operates at the 5GHz Unlicensed National Information Infrastructure (UNII) band with turbo mode. Data is transmitted over a half-duplex radio channel operating at up to 108 Megabits per second (Mbps) in turbo mode. The default mode is 54 Mbps. Power over Ethernet The Access Point 2220 supports Power over Ethernet (PoE). You need not configure anything to access power from a IEEE 802.3af-draft-compliant switch. To use PoE to power your Access Point 2220, plug in a cable to the RJ-45 port on the back of the Access Point 2220 and connect the other end of the RJ-45 cable to a switch that delivers IEEE 802.3af-draft-compliant power. When you are using PoE, you do not require separate AC power. The Access Point 2220 draws 8.5 W. The Access Point 2220 uses both spare and signal RJ-45 power pairs. LED Indicators The Access Point 2220 includes four status LED indicators, as described in the following figure and table. 214853-A AccessPointUG.book Page 15 Thursday, February 27, 2003 12:22 PM [Final Draft—Nortel Confidential] Preface 15 Figure 1 LED indicators Power Ethernet Link/Activity 802.11b 802.11a Wireless Wireless Link/Activity Link/Activity Table 1 LED Indicators LED Status Description Ready On Indicates that power is being supplied.

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 Map (DTIM) packet interval value. The DTIM indicates how often the MAC layer forwards multicast traffic. This parameter is necessary to wake up stations that are using Power Save mode. The DTIM is the interval between two synchronous frames with broadcast information. If you set the value to 2, the access point will save all multicast frames for the BSS and forward them after every second beacon. Having smaller DTIM intervals delivers multicast frames in a more timely manner, causing stations in Power Save mode to wake up more often and drain power faster. Having higher DTIM values reduces the power used by stations in Power Save mode, but delays the transmission of multicast frames. (Default: 5 Beacons) Fragment Length (256-2347) The “Fragment Length” 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 speed up the retransmission of smaller frames. 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: 2347) 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 enabled 214853-A AccessPointUG.book Page 41 Thursday, February 27, 2003 12:22 PM [Final Draft—Nortel Confidential] Chapter 2 System Configuration 41 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 medium may not be aware of each other. The RTS/CTS mechanism can solve this “Hidden Node Problem.” (Default: 2347) Preamble Setting The 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 the NIC.

(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 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 medium may not be aware of each other. The RTS/CTS mechanism can solve this “Hidden Node Problem.” (Default: 2347) Using the Nortel Networks Wireless LAN Access Point 2220 AccessPointUG.book Page 46 Thursday, February 27, 2003 12:22 PM [Final Draft—Nortel Confidential] 46 Chapter 2 System Configuration Security WEP (Wired Equivalent Privacy) Figure 23 Security screen Authentication Type Setup You may choose either “Open System” or “Shared Key.” (Default: Open System) If Shared Key is enabled, WEP should be enabled and at least one shared key should be defined. 214853-A AccessPointUG.book Page 47 Thursday, February 27, 2003 12:22 PM [Final Draft—Nortel Confidential] Chapter 2 System Configuration 47 Data Encryption You may choose “Enable” to enhance your network security with WEP data encryption (Default: Disable) If Shared Key is enabled, WEP should be enabled and at least one shared key should be defined.

The wireless network cards, adapters, access points and wireless access point can be configured as: • • • Ad hoc for departmental or SOHO LANs Infrastructure for wireless LANs Infrastructure wireless LAN for roaming wireless PCs Network Topologies Ad Hoc Wireless LAN (no AP or Bridge) 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 or SOHO operation.

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. Wired LAN Extension to Wireless Adapters File Server Desktop PC Switch Notebook with Wireless PC Card Adapter Access Point PC with Wireless PCI Adapter Infrastructure Wireless LAN for Roaming Wireless PCs The 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. 214853-A AccessPointUG.book Page 55 Thursday, February 27, 2003 12:22 PM [Final Draft—Nortel Confidential] Chapter 3 Network Configuration and Planning 55 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.
