Wireless Interface -- Setting up WLANs Virtual AP (VAP) In this section, you can define and set-up a Virtual AP (VAP), as well as viewing the status of any VAPs that were previously defined.
WBSn-2400 User Guide Page - 19 - To define a VAP: 1. Navigate to Configuration => Wireless => VAP. 2. Specify the parameters according to the parameter value definitions in the below table. Parameter Description Name Name of the VAP Permitted length: 1-32 alphanumeric characters (all alphanumeric characters are allowed, with spaces, dashes, or underscores) Hidden Indicates whether these SSID parameters are broadcast to the public, or hidden, only accessible by authorized users. WMM Classification Packet prioritization over Wi-Fi is based on four access categories defined by the WMM standard: • Voice traffic • Video traffic • Best effort traffic • Background traffic A packet sent to the Ethernet interface of the base station is classified as one of the Access categories. This classification is performed based on DSCP or W8021p priorities. For information about classification configuration, please see QoS Packet Priority. BH SSID Indicates whether this SSID is configured as a backhaul SSID. Values: • Enabled • Disabled 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 Address List. Security Mode Choose between the following: • None (Open) • WEP (Shared key) • WPA (PSK and RADIUS) • WPA2 (PSK and RADIUS) For more information about authentication and encryption, please see the Security, Authentication and Encryption Modes table.

The limit can be set to any value between 0 and 50, regardless of the security of the VAP. QoS (Quality of Service) Packet Priority Wireless Multimedia Extensions (WME), also known as Wi-Fi MultiMedia (WMM), provide basic QoS features to IEEE 802.11n networks. WMM prioritizes traffic on the wireless interface using four Access Categories (AC): • Voice • Video • Best Effort • Background 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 Wi-Fi, (for example, Voice over IP (VoIP)).
WBSn-2400 User Guide Page - 21 - Note: In order to allow QoS through the WBSn-2400, both ends of the network (CPE on the wireless side and the switch/router 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 is selected, WBSn inspects the incoming layer-2 packets and determines the WMM priority according to the VLAN-priority 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 wire-line 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. To view the status of a VAP: To view the status of any or all defined VAPs, navigate to Status => Wireless => VAP. Authentication Combinations WBSn-2400 allows the following authentication types and combinations. • The WPA authentication automatically presumes that the basic 802.11 authentication is Open. WPA defines advanced authentications, either PSK (Pre-Shared Key) or RADIUS. The initial keys are determined during the last phase of the WPA authentication. • [To be supported in future versions.] When RADIUS Authentication is used, the RADIUS server can determine which VLAN belongs to which user. Note: WBSn-2400 supports multiple VLAN per VAP. • Each VAP can have a different RADIUS server configured. This allows for the transportation of several networks over the same infrastructure of WBSn-2400 Encryption Methods Legacy 802.11 clients can either connect using the Open authentication (see above), or WEP. In WEP, the encryption key can be either 40bit or 104bit. In WPA, WBSn-2400 supports TKIP and AES encryptions.

Network/Ethernet Interface – Setting up WLANs A WLAN is the combined entity of VAPs and VLANs. Each VLAN has a unique IP address, which you must configure. It is possible to create several networks that work in parallel on the same WBSn-2400. This can be done by creating several VAPs mapped to several VLAN. Each VAP will represent a different broadcast domain on the wireless interface, isolated from other VAPs by using different broadcast keys, with the broadcast domains on the Ethernet interface separated by the VLAN. To Configure the Default IP 1. Navigate to Configuration => Network => IP Configuration to specify the default IP for your VLAN. 2. Click Add (or to specify an existing IP configuration, click Edit). The following dialog is displayed:
WBSn-2400 User Guide Page - 25 - 3. Complete the fields according to the parameters described in the table below.

A maximum of 4096 VLANs can be configured on WBSn. Once you have configured the VLANs, you will then map them to different wireless parameters, to achieve different capabilities according to your requirements. You can also configure one VLAN as the Management VLAN in the WBSn-2400 system. The purpose of this is to segment the Management and the Clients data traffic. It also provides an option for customers to keep an Open SSID for public traffic and simultaneously manage the WBSn-2400 traffic over a separate VLAN (that can be linked to a secured SSID). The management VLAN can be selected out of the enabled VLAN list. To Configure a VLAN 1. To specify a new VLAN, navigate to Configuration => Network => Bridge. 2. Expand the VLANs Configuration window, and click Add (or Edit) to configure the VLAN Parameters. A pop-up box with the following parameters is displayed. Parameter Description and values VLAN ID This ID should be unique and must be supported by the backbone equipment that is connected to the WBSn through the Ethernet port. VLAN Name Edit the VLAN name as required. Ethernet Determine whether the VLAN is configured in the Ethernet interface, and define whether it is tagged or untagged. VAP 1-6 Determine whether the VLAN is configured in any of the VAP interfaces and define whether they are tagged untagged, or none. 3. Scroll back up to the VLANs section, and specify a VAP for the VLAN. Once you have at least one VLAN defined, you can then specify the Management VLAN. Tagging VLAN When configuring more than one VAP per WBSn unit, a VLAN can be created. Each VLAN should be tagged with a different VLAN ID so that networks can be identified at backbone entry. The default VLAN has a VLAN ID that is equal to 1, and has tagging disabled by default, leaving the data untagged.
WBSn-2400 User Guide Page - 26 - Bridge Enables you to configure how VLANs are defined and structured in the system, and with which VAP each VLAN is paired. For more information, see Configuring a VLAN. Mapping VLANs to VAPs VAPs are configured as Wireless interfaces. The table below shows the mapping of VLANs to VAPs. Interfaces Index VLAN ID Ethernet Management VAP1 VAP2 VAP 3 VAP4 1 3599 √ √ √ 2 101 √ √ 3 73 √ √ √ As displayed in the above table, a single VLAN can be mapped to multiple VAPs (e.g. VLAN 73), and multiple VLANs can be passed to a single VAP (e.g. both VLAN 101 and VLAN 73 are linked to VAP 1). In such a situation, one untagged VLAN can be defined per interface (e.g. Ethernet, VAP). When a VLAN is configured to be tagged on a VAP, a CPE that supports VLAN tagging on the wireless interface must be used.

WBSn-2400 User Guide Page - 34 - Appendix B: Frequently Asked Questions Q: Does the WBSn-2400 base station support standard off-the-shelf 802.11b/g/n NIC cards? A: Yes, the WBSn-2400 base station supports the 802.11b/g/n standard. Q: I have WEP configured on my radio but I am unable to connect to the Internet. A: WBSn base station supports all the security modes defined by 802.11 and Wi-Fi Alliance: Open, WEP, WPA and WPA2. In the case of WEP mode, both 64-bit (also known as 40-bit) and 128-bit WEP (also known as 104-bit) encryptions are supported. In addition, both Open and Shared Key Authentications are supported in WEP mode. Note: Security WEP can only be configured on VAP-1. Note: Both ends must have the same configuration for data transfer. The key length and the key itself must match at both ends, as must the Authentication type. WBSn requires that you enter the WEP key in hexadecimal format. Some devices allow ASCII text or a pass phrase. This value must be converted into hexadecimal format and entered into the WBS. If the devices have multiple keys, the same key number must be used on both devices. For example; if WEP Key 1 is used on one device, WEP Key 1 must be used on the WBSn. Q: How do I log in to the WBSn Management page? A: Access to the WBSn is gained through the following IP address and credentials: Default IP: http://192.168.1.1/24 Username: admin Password: admin To access WBSn, ensure that your computer is set to an IP address similar to 192.168.1.2, with a subnet mask of 255.255.255.0. Once you have configured your computer, open a web browser and browse to: http://192.168.1.1. The login prompt for the WBSn should now be displayed. Q: How do you set up an IP address on the WBS? A: See this section in the User Guide. Q: How do you extend the coverage of the WBS? A: There are several ways to extend the WBSn coverage area. These are the most important methods: 1. Increase the transmitter power level parameter of the existing WBSn in order to extend the coverage. 2. Position the WBSn base stations optimally at least 1m away from any metal object. 3. Use a strong transmission client (CPE). 4. Increase the transmission/reception capabilities of the client antenna by using an RF Booster. 5. Run ACS, and try working in a different channel in which there is less interference. Q: What is the typical range for a WBSn base station? A: The answer to this question depends on a number of factors including: • The data rate (bandwidth) that you expect to receive at remote locations • The device (CPE/NIC) that resides at the remote end • The level of interference at the active channel
WBSn-2400 User Guide Page - 35 - • The terrain of the covered area. In rural areas where the WBSn base station is installed relatively high (10m above other buildings), and there are no interferences, the range can be up to 20 km. Q: How can I determine the best channel to work in? A: Use the ACS feature to search for a clean frequency Q: Does WBSn base station support roaming? A: The Wavion Base Station supports the part of 802.11f, which supports handover between access points that reside on the same Layer-2 domain. The WBSn handover implementation sends a Layer-2 packet with the source address of a newly associated client. This packet is sent as broadcast message allowing all Layer-2 devices in the network to update their MAC address caches. This solution will work if the backhaul network is configured as a flat Layer-2 network. When the network is composed by multiple IP subnets, another device (e.g. a session controller) should handle roaming across subnets. Q: Is it possible to co-locate a number of WBSn base stations?? A: Yes, three WBSn units can be co-located. A minimum of 8 meters separation is recommended when all units are on the same RF channel. However, the units will suffer from throughput performance due to mutual interference. A one-meter separation is possible when units are operating on different RF channels 1,6,11. It is highly recommended to have as much distance as possible between units and to use RF channels 1,6,11 in order to reduce throughput degradation. We recommend that you avoid installing the units at the same height, by leaving a vertical distance of at least 1 meter between them. Q: What is the minimum distance required between two WBSn units? A: Two meters is the minimal recommended separation. Q: What are the tower installation requirements? A: WBSn must be installed at least 1 meter away from any adjacent metal object. Q: What are the pole installation requirements? A: WBSn must be installed with antenna higher than the end of the pole. Q: What is the nominal noise level for optimal performance of WBSn? A: Nominal noise level without interference is -97dBm. Utilize the ACS feature to search for a clean frequency with a noise level between -85dBm to -97dBm. Higher values indicate higher noise levels due to interference. Q: What is the maximum Ethernet cable length that can be used with a POE? A: The maximum cable length is 100 meters. Q: Where is the WBSn reset button? A: The reset pin hole button is located below the USB port. To reset the system to factory default parameters press the button until the STATUS LED is on steady with a red light.
WBSn-2400 User Guide Page - 36 - Q: How many clients can associate to WBSn? A: The WBSn can physically handle up to 250 MAC addresses. However, because Wi-Fi is a shared platform and every Wi-Fi base station acts as a wireless hub, the performance of each user decreases as the number of users increases. Q: Is it possible to limit the number of associated clients? A: Yes. The WBSn can support up-to 256 associated clients per radio (supported by v1.1 onwards). The WBSn can limit the number of clients associated to any value between 0 and 50. Client association will be refused after the limit is reached. For more information, see the Security, Authentication and Encryption Modes table. Q: How to deny association to specific MAC addresses? A: The list of MAC addresses you wish to block can be uploaded or enter manually. For more information, see MAC Access List. Q: Does the WBSn support QoS? A: Yes. The WBSn support QoS while implementing the WMM protocol. For more information, see the Security, Authentication and Encryption Modes table.
