Italy
This product meets the National Radio Interface and the requirements
specified in the National Frequency Allocation Table for Italy. Unless this
wireless LAN product is operating within the boundaries of the owner’s
property, its use requires a “general authorization.” pplease check with
www.communicazioni.it/it/ for more details.
Questo prodotto é conforme alla specifiche di Interfaccia Radio Nazionali e rispetta il

Noway, Switzerland and Liechtenstein
Although 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 Power
The 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).
Antennas
The 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 Frequency
The 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.

Why 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:
z802.11a
Operates in the 5 GHz range with a maximum speed of 54 Mbps.
z802.11b
Operates 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.
z802.11g
Supports 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.

6 Introduction
Product Overview
Part 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 Security
The 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.

Deployment Flexibility
Xirrus’ 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 Patterns
Figure 2 depicts the following two scenarios:
zFull pattern coverage
All 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 coverage
If 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.

Remote 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.

Enterprise 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 Page
In 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.

10 Introduction
Key Features and Benefits
This 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 Performance
The 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.

Extended Coverage
One 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.
