See Lightning Protection. 2 6 diameter pole (on which to mount the unit) Extender (optional) Ensure a safe and secure environment Warning Follow these guidelines to ensure safe operation of the WBSn 2450 base station: Connect the PoE injector to the unit using only a straight Ethernet cable. Do not use crossed cables between the PoE injector and the unit! Do not touch or move the antennas while the unit is switched on. Make sure the antennas are connected when operating the radio or attempting to transmitt data, otherwise, the radio may be damaged. Do not hold the antenna close to or touching any exposed parts of the body, especially the face or eyes, while transmitting. The use of wireless devices on airplanes is governed by the Federal Aviation Administration (FAA). (US only) The use of wireless devices in hazardous locations is limited to the constraints posed by the safety directors of such environments. The use of wireless devices in hospitals is restricted to the limits set forth by each hospital. Do not operate a portable transmitter near unshielded blasting caps or in an explosive environment. The Alvarion WBSn2450 must be used only with Alvarionapproved components and antennas. Note: The Federal Communications Commission (FCC) with its action in ET Docket 968 has adopted a safety standard for human exposure to RF electromagnetic energy emitted by FCC certified equipment. Proper operation of the Alvarion WBSn according to the instructions found in this manual, results in user exposure that is substantially below the FCC recommended limits. 10

11 To ensure optimal performance for WBSn, select the location for the equipment using the following guidelines: The antenna should be directed towards the area intended to be covered, with maximum possible lines of sight for client locations. Generally speaking, the higher the placement of the antenna, the better the link quality achievable, however, the higher the installation the greater interference that the base station is exposed to. Consider best installation spot that maximizes coverage and minimizes interference. Two meters is the minimal recommendedd separation for Sector base station units (back to back). If omnidirectional units are in use, the minimum separation is 10 meters. The location of the unit should enable easy access for installationn and testing. When installing in locations where other devices exist that operate in the same frequency range, ensure that recommended distances are adhered to. For more information, see here. The ideal height at which a base station should be installed is a minimum of 3 meters above the rooftops of the buildings within the coverage zone. The omnidirectional unit should be installed at the highest point the pole. This is to ensure that there is no interference caused by the close proximity of the antenna to other objects. Where this is not possible, the unit should be kept at least 1 meter from the pole, using a horizontal bar. Keeping the maximum distance possible from an RF radiating source is recommended. Preparing the installation site Only experienced installation professionals who are familiar with local building and safety codes and are licensed, wherever applicable, by the appropriate government regulatory authorities, should install outdoor units and antennas. Warnings Important! This device should be installed in an area with restricted access. Do not modify the construction of this product. Modifying the operating frequency or enhancing the transmit output power through the use of external amplifiers or other equipment is illegal. This device is for outdoor or indoor use on the conditionn that operation of this device causes no harmful interference to authorized radio stations. This device shall not influence aircraft security and/ /or interfere with legal communications. If this device is found to cause interference, the operator of this equipment shall cease operating this device immediately. How to prepare the site: Ascertain the existence of potential posts or poles to which a base station could be attached. Consider the axis of the post, its placement, and whether extenders are required. Follow the appropriate electrical and building codes to ensure safe and durable wiring. The total length of the Ethernet cable connecting the unit to the network device (PC, switch, router, and so on) should not exceed 100 meters. Theree is no limitation on the length of the cable connecting the PoE to the unit, as long as the combined length of the cables from the network device through the PoE and to the unit does not exceed 100 meters. 111

Specify the longitude of the base station location. Specify the latitude of the base station location. Specify the direction to which the base station is directed Setting Management VLAN The management VLAN enables administrators to manage the WBSn over a dedicated VLAN. The management VLAN can be selected from the enabled VLAN list. Note: The management VLAN can be linked to a secured SSID/VAP if the administrator so requires. In such a case, the VAP can have additional security properties assigned to it. Note: Only one VLAN can be defined as the Management VLAN in the WBSn system. Prior to specifying the management VLAN, you must have at least one VLAN defined. See Bridge Configuration for more information. WBSn also supports the assignment of dynamic VLANs to WiFi clients. This mode is supported per VAP (Virtual AP). In this mode, the VLANs are determined by a RADIUS server, at the time of association and authentication of clients to a specific VAP. 26

27 3.33 Wireless Interface Virtual AP (VAP) In this section, you can define and setup a Virtual AP (VAP), as well as viewing the status of any VAPs that were previously defined. To define a VAP: 1. Navigate to Configuration => Wireless => VAP. 2. Specify the parameters according to the parameter value definitions in the below table. Name Parameter Description Name of the VAP to be used as the SSID (Service Set Identifier) Permitted length: 132 alphanumeric characters (all alphanumeric characters are allowed, with spaces, dashes, or underscores) Hidden WMM Classification Indicates whether these SSID parameters are broadcast to the public, or hidden, only accessible by authorized users that know the SSID Values: DSCP Auto W8021p (IEEE 802.1p) Packet prioritization over WiFi is based on four access categories defined by the WMM standard: Voice traffic Video traffic Best effort traffic Background traffic A packet sent after being classified as one of the Access categories. The classification on the Ethernet interface is performed based on DSCP or W8021p priorities, while the classification in the Wireless interfacee is performed based on WMM Access Categories. For information about classification configuration, please seee QoS Packet Priority. Dynamic VLAN WBSn supports the assignment of dynamic VLANs to WiFi clients. This mode is supported per VAP (Virtual AP). In this mode, the VLANs are determined by a RADIUS server, at the time of association and authentication of clients to a specific VAP. Values: Enabled Disabled 27

28 QinQ Parameter Description WBSn supports IEEE 802.1ad QinQ allowing two VLAN tags, external and internal, to be inserted into a single Ethernet frame. The internal VLAN tag is determinedd by RADIUS Server at the time of CPE authentication, and the external VLAN tag is determined upon the VAP to which the CPE is connected. This feature is supported and configured per VAP. Enabled Disabled Note: Can only be enabled when DynamicVLAN is enabled. ACL Group The ACL (Access Control List) controls who can access the VAP. A list is created according to specific parameters, and given a unique name, and will either define an Accept group (those users permitted VAP access), or a Reject group (those users denied VAP access). For more information, see MAC Addresss List. Limit Number of Stations Security Mode Enables you to limit the number of users per VAP. Note: There is not validation on aggregated VAPs. Choose between the following: None (Open) WEP (Shared key) WPA (PSK and RADIUS) WPA2 (PSK and RADIUS) For more informationn about authentication and encryption, please see the Security, Authentication, Encryption Modes and Maximum Associations table. Limit number of stations Controls the number of clients associated to the base station. If Enable Limit is selected, a numerical limit can be specified. If Enable Limit is not selected, any number of clients can associate to the base station. (Default) There is no default limitation on the number of associations supported. WBSn supports up to 256 associated clients per radio, utilizing the Open security mode. In other security modes the maximum number of associated clients is different. For more information, please refer to the Security, Authentication, Encryption Modes and Maximumm Associations table. WBSn supports the capability of limiting the number of maximum associations per VAP. The limit can be set to any value between 0 and 50, regardlesss of the security of the VAP. To view the status of a VAP: To view the status of any or all defined VAPs, navigate to Status => Wireless => VAP QoS (Quality of Service) Packet Priority Wireless Multimedia Extensions (WME), also known as WiFi MultiMedia (WMM), provide basic QoS features to IEEE a/b/g/n networks. WMM prioritizes traffic on the wireless interface using four Access Categories (AC): Voice Video Best Effort Background 28

29 Traffic is prioritized by these access categories, and the implementation defined by the WMM standard. Traffic is therefore suitable for applications that require QoS over WiFi, for example, Voice over IP (VoIP). Note: In order to allow QoS through the WBSn, both ends of the network (CPE on the wirelesss side and the switch/routerr on the Ethernet side) should support the same priority tagging. This permits the marking of a specific packet with a specific priority. WBSn supports DSCP, 802.1p and Auto priority tagging. When DSCP is selected, WBSn inspects the incoming IP packets and determines the WMM priority according to the DSCP priority bits. When W8021p ( IEEE 802.1p) is selected, WBSn inspects the incoming layer2 packets and determines the WMM priority according to the VLANpriority bits. When Auto mode is selected, WBSn checks whether a VLAN tag exists, and if it does, it determines the priority according to the VLAN priority. Otherwise, the priority is determined by the DSCP value. Downlink (data sent from the network to the user), a packet from the wireline network is received by the WBSn, and its priority detected. The packet will be prioritized over the air according to WMM AC prioritization. When the packet reaches the CPE, the CPE passes it to its LAN interface according to the packet definition. Uplink (data sent from the user to the network), the CPE will detect the priority (as defined at the CPE) and will pass the frame with the correct WMM AC characteristics, thus providing the priority classification on the wireless side. 3.4 Security WBSn security capabilities utilize various levels of authenticationn and encryption methodologies Authentication WBSn allows the following authentication types and combinations. Each VAP can have a different RADIUS server configured. This allows for the authentication of several networks over the same infrastructure of WBSn base stations. When RADIUS Authentication is used, the RADIUS server can determine which VLAN belongs to which user. Note: WBSn supportss multiple VLAN per VAP. The WPA/WPA2 authentication automatically presumes that the basic authentication is Open. WPA/WPA2 defines advanced authentications, either PSK (PreShared Key) or RADIUS. The initial Encryption keys are determined during the last phase of the authentication. For the 802.1x with RADIUS Server authentication framework, the following EAP methods are supported: EAPTLS, PEAP, EAPTTLS, EAPSIM, EAPAKA. For more details regarding EAPSIM, see EAP for GSM Subscriber Identity Module (EAPSIM). MAC Authentication with RADIUS server for open sessions. To configure this option select "Open (802.1x + MAC Auth)". EAP Authentication for Open session. For more information, see Unique Enhancements for Open Security Sessions EAP for GSM Subscriber Identity Module (EAPSIM) EAPSIM is used for authentication and session key distribution using the Subscriber Identity Module (SIM) from the Global System for Mobile Communications (GSM), by communicating with the Authentication Centre (AuC), and thereby replacing the need for a preestablished password between the client and the AAAA server. GSM cellular networks use a subscriber identity module (SIM) card to authenticate users. EAPSIM uses a SIM authentication algorithm between the client and an Authentication, Authorization and Accounting (AAA) server, enabling mutual authentication between the client and the network. 29

30 In terms of WBSn, the VAP is configured according to the specifications of the WPA2RADIUS authentication, and the rest of the authentication is performed in a transparent manner, by WBSn Unique Enhancements for Open Security Sessions Generally, for WPA and WPA2 security mechanisms, RADIUS authentication (802.1x) is available only for encrypted sessions (WPA or WPA2). With this enhancement, x authentication is also supported for the open session mode (by setting Open (802.1x Auth) ). When such authentication is in use a supplicant SW on the client device is required to handle EAP (Extended Authentication Protocol) over the open session Encryption Methods Legacy clients can either connect using the Open authentication, or WEP. In WEP, the encryption key can be either 40bit or 104bit. In WPA, WBSn supports TKIP and AES encryptions. In WPA and WPA2, WBSn supports TKIP and AES encryptions. Note: The n standard only permits the use of AES keys when operating within a secured network. Therefore, it is strongly recommended that the VAPs will be either Open or WPA2 AES secured. Note: In case TKIP or WEP clients are expected to connect, they must connect using their g interface. Additionally, a WEPsecured VAP can only be configured for first VAP (i.e. VAP 1) Security, Authentication, Encryption Modes and Maximum Associations The table below describes the number of maximum associationss according to the security mode in use. Security Mode Authenticationn Mode Encryption Mode Max Associations (per band) None Open system None 256 WEP (Only available for the first defined VAP) Shared key WEP/40 WEP/ WPA PSK (Preshared key) TKIP 55 Radius TKIP + AES 110 WPA2 PSK (Preshared key) AES 110 Radius AES + TKIP None 802.1x None 256 None 802.1x +MAC None Radius Accounting Accounting is required for billing and statistical purposes. With an internal Access Controller license installed, a WBSn provides peruser time and throughput RADIUS accounting messages, without the need for any additional external hardware. This feature is currently available for all wireless clients whether associated to secured (e.g. WPA2RADIUS) or nonsecured (i.e. Open) VAPs. In future versions Accounting will also be available for nonwireless clients connected through wireless CPEs, and for users authenticated using WebAuthentication portal. The Accounting Start and Interim messages include information about the connected wireless client, including its IP address, if known to the base station (base on DHCP messages exchanged with the client). 30
