Se non viene installato all’interno del proprio fondo, l’utilizzo di prodotti wireless LAN richiede una “autorizzazione Generale.” Consultare www.communicazioni.it/it/ per maggiori dettagli.Noway, Switzerland and LiechtensteinAlthough Norway, Switzerland and Liechtenstein are not EU member states, the EU Directive 1999/5/EC has also been implemented in those countries.Calculating the Maximum Output PowerThe regulatory limits for maximum output power are specified in EIRP (radiated power). The EIRP level of a device can be calculated by adding the gain of the antenna used (specified in dBi) to the output power available at the connector (specified in dBm).
AntennasThe Xirrus Wireless LAN Array family of products employs integrated antennas that cannot be removed and which are not user accessible. Nevertheless, as regulatory limits are not the same throughout the EU, users may need to adjust the conducted power setting for the radio to meet the EIRP limits applicable in their country or region. Adjustments can be made from the product’s management interface—either Web Management Interface (WMI) or Command Line Interface(CLI).Operating FrequencyThe operating frequency in a wireless LAN is determined by the access point. As such, it is important that the access point is correctly configured to meet the local regulations. See National Restrictions in this section for more information.If you still have questions regarding the compliance of Xirrus products or you cannot find the information you are looking for, please contact us at:Xirrus, Inc.370 North Westlake Blvd, Suite 200Westlake Village, CA 91362USATel: 1.805.497.0955Fax: 1.805.449.1180www.xirrus.com

Wireless LAN ArrayIntroduction 5Why Choose the Xirrus Wireless LAN Array?In 2003 there were approximately 30,000 Wireless Local Area Networks (WLANs) operating in the public domain. Research suggests that the number will more than quadruple by 2006. Enterprise WLANs in the private sector are also becoming increasingly common as businesses strive for greater flexibility in the workplace and the need for employee mobility rises. The only requirements for an effective wireless deployment are a power source, a couple of screws, and an imagination.Wireless LAN is also fully compatible with standard Ethernet protocols, so connectivity with existing wired infrastructures is transparent to users—they can still access and use the same applications and network services that they use when plugged into the company’s wired LAN infrastructure (it’s only the plug that no longer exists).Wireless LAN has come a long way in the past few years and now offers the performance, reliability and security that Enterprise customers have come to expect from their networks. The technology is being driven by three major IEEE standards:z802.11aOperates in the 5 GHz range with a maximum speed of 54 Mbps.z802.11bOperates in the 2.4 GHz range with a maximum speed of 11 Mbps. It has a range of about 100 meters indoors and 300 meters outdoors.z802.11gSupports a higher transmission speed of 54 Mbps in the 2.4 GHz range and is backwards compatible with 802.11b.Whether you’re a small company with just a handful of employees, or a large corporation with thousands, wireless has the scalability and flexibility to serve your needs.
Wireless LAN Array6 IntroductionProduct OverviewPart of the family of Xirrus products, the Wireless LAN Array is a high capacity, multi-mode device designed for the Enterprise market, with twice the range and up to sixteen times the capacity of competitive wireless products.Figure 2. Wireless LAN Array (XS-3900)The Xirrus Array (regardless of the product model) is Wi-Fi® compliant and simultaneously supports 802.11a, 802.11b and 802.11g clients. Enterprise class features such as VLAN support and multiple SSID capability enable robust network compatibility and a high level of scalability and system control. The optional Xirrus Wireless Management System (XM-3300) allows global management of hundreds of Arrays from a central location.The XS-3700 and XS-3500 versions of the Wireless LAN Array deliver a correspondingly lower capacity than the XS-3900.Enterprise Class SecurityThe latest and most effective wireless encryption security standards, including WPA (Wi-Fi Protected Access) with 802.11i AES (Advanced Encryption Standard) are provided with the Xirrus Array. In addition, the use of an embedded RADIUS server (or 802.1x with an external RADIUS server) ensures user authentication—multiple Arrays can authenticate to the optional XM-3300 ensuring only authorized Xirrus Wireless LAN Arrays become part of the wireless network. Rogue AP detection and site monitoring is performed in the background by the Array automatically.
Wireless LAN ArrayIntroduction 7Deployment FlexibilityXirrus’ unique multi-radio architecture generates 360 degrees of sectored high-gain 802.11a/b/g coverage that provides extended range and the highest possible data rates for a large volume of clients. Each sector can be controlled automatically or manually, creating a pattern of wireless coverage perfectly tailored to individual customer needs. For example:Figure 3. Wireless Coverage PatternsFigure 2 depicts the following two scenarios:zFull pattern coverageAll radios are activated with coverage spanning 360 degrees. If within range, clients will always receive coverage regardless of their geographic position relative to the Array.zPartial pattern coverageIf desired, the Xirrus Array can be deployed close to an exterior wall. In this case, half of all available radios have been deactivated to prevent redundant signals from “bleeding” beyond the site’s perimeter wall. This configuration may also be used in those cases where you want to restrict wireless coverage to selected areas of the building’s interior.outside wall
Wireless LAN Array8 IntroductionRemote DC Power System (Optional)The Xirrus Remote DC Power System (XP-3100) provides distributed DC power to your Array (DC version) deployments, eliminating the need to provide an AC power outlet in close proximity to the unit(s).In the following example, DC power is supplied to four Xirrus Arrays while utilizing only one AC power outlet.Figure 4. Remote DC Power DistributionAC Input to XP-3100DC Output to Xirrus ArraysXP-3100
Wireless LAN ArrayIntroduction 9Enterprise Class Management The Xirrus Array can be configured with its default RF settings, or the RF settings can be customized using the Array’s embedded Web Management Interface (WMI). The WMI enables easy configuration and control from a graphical console, along with a full compliment of troubleshooting tools, reports and statistics.Figure 5. WMI: Array Status PageIn addition, a fully featured Command Line Interface (CLI) offers IT professionals a familiar management and control environment. SNMP (Simple Network Management Protocol) is also supported to allow management from an SNMP compliant management tool, such as the optional Xirrus Wireless Management System.#For deployments of more than two Arrays, we recommend that you use the Xirrus Wireless Management System (XM-3300). The XM-3300 offers a rich set of features for fine control over large deployments.
Wireless LAN Array10 IntroductionKey Features and BenefitsThis section describes some of the key product features and the benefits you can expect when deploying the Xirrus Array (the XS-3900 product is highlighted in this section).High Capacity and High PerformanceThe XS-3900 easily handles time-sensitive traffic, such as voice, and can enable wireless connectivity for 1,024 users. The unit includes two Gigabit uplink ports for connection to the wired network. A total of sixteen IAPs provides a maximum wireless capacity of 864 Mbps, which offers ample reserves for the high demands of current and future applications. Of the sixteen IAPs, twelve operate in the 802.11a mode and four operate in any combination of 802.11a, 802.11b and 802.11g.If desired, IAP (radio) abg2 can also be configured in RF monitoring and rogue AP detection mode.Figure 6.

Wireless LAN ArrayIntroduction 11Extended CoverageOne XS-3900 solution enables you to replace up to sixteen access points (includes one omnidirectional IAP for monitoring the network). Fifteen IAP radios with integrated directional antennas provide increased wireless range and enhanced data rates in all directions. With a Xirrus Array deployed, far fewer access points are needed for your wireless network. Radio abg2 (see Figure 6) can be switched to use an integrated omnidirectional antenna—for listening only—and can be dedicated to the tasks of site monitoring and rogue AP detection.Figure 7.

Wireless LAN Array12 IntroductionNon-Overlapping ChannelsComplete use of non-overlapping channels limits interference and delivers maximum capacity. On the XS-3900, all 16 non-overlapping channels are fully utilized across the 5Ghz and 2.4Ghz spectrums (12 across the 5GHz spectrum and 4 across the 2.4GHz spectrum).Secure Wireless AccessMultiple layers of authentication and encryption ensure secure data transmissions. The Xirrus Array is 802.11i compliant with encryption support for 64 bit and 128 bit WEP, and WPA with TKIP and AES encryption.Authentication support is provided via 802.1x, including PEAP, EAP-TLS, and EAP-TTLS.Applications EnablementQoS (Quality of Service) functionality combined with true switch capabilities enable high density Voice over Wireless LAN deployments. Compliant with 802.1p and 802.1q standards.SDMA OptimizationSDMA (Spatial Division Multiple Access) technology provides full 360° coverage while allowing independent channel and power output customization. Also supports fast inter-zone handoffs for time-sensitive applications and roaming support.Easy DeploymentThe Xirrus Wireless Management System (XM-3300) offers real time monitoring and management capabilities of the wireless network—ideal for the Enterprise market. It also allows you to import floor plans to help you plan your deployment. The Xirrus Wireless LAN Array chassis has a plenum rated, lockable and tamper resistant case.
