OVERVIEW

This chapter introduces the Wireless LAN Array, including an overview of its key features and benefit s, and a
detailed listing of the product’s physical, environmental, techn ology and regulatory specifications. T opics discussed
in this chapter include:

• “Product Overview” on page 1-1

• “Key Features and Benefits” on page 1-3

• “Product S pecifica tions (WFX-3900 and WFX- 3700 )” on page 1-5

• “Product S pecifica tions (WFX-3500) ” on page 1-9

PRODUCT OVERVIEW

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.

Wireless LAN Array (WFX-3900/3700/3500)

The Array (regardless of 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 Wireless Management
System (WFX-3300) allows global management of hundreds of Arrays from a central location.

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 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 WFX-3300 ensuring only authorized 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

ADC’s 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 t ailored to individual customer
needs. For example:

AIWS-UM-4003-01 1-1

Chapter 1: Overview December 22, 2005

Figure 1-1 on the previous page depicts the following two scenarios:

• Full 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.

• Partial pattern coverage – If desired, the 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 Remote DC Power System (WFX-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 (Figure 1-2), DC power is supplied to four Arrays while utilizing only one AC power outlet.

AC Input to WFX-3100

DC Output to Arrays

Figure 1-2. Remote DC Power Distribution

Enterprise Class Management

The 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 contr ol from a graphical
console, along with a full compliment of troubleshooting tools, reports and statistics.

In addition, a fully featured Command Line Interface (CLI) of fers IT professionals a familiar management and contro l
environment. SNMP (Simple Network Management Protocol) is also supporte d to allow management from an
SNMP compliant management tool, such as the optional Wireless Management System.

Note: For deployments of more than two Arrays, ADC recommends you use the Wireless Management

System (WFX-3300). The WFX-3300 enables control of large deployments.

December 22, 2005 Chapter 1: Overview

KEY FEATURES AND BENEFITS

This section describes some of the key product features and the benefits you can expect when deploying the Array
(the WFX-3900 product is highlighted in this section).

High Capacity and High Performance

The WFX-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 tot al 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.

Mode(s) IAP number

Figure 1-3. Layout of IAPs (WFX-3900)

Extended Coverage

One WFX-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 pro vide increased wir eless range
and enhanced data rates in all directions. With an Array deployed, far fewer access points are needed for your
wireless network. Radio abg2 (see Figure 1-3) 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.

Non-Overlapping Channels

Complete use of non-overlapping channels limits interference and delivers maximum capacity. On the WFX-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 Access

Multiple layers of authentication and encryption ensure secure data transmissions. The 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 Enablement

QoS (Quality of Service) functionality combined with true switch capabilities enable high density Voice over Wireless
LAN deployments. Compliant with 802.1p and 802.1q st andards.

SDMA Optimization

SDMA (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 Deployment

The Wireless Management System (WFX-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 Wireless LAN Array chassis has a plenum rated, lockable and tamper resistant case.

INSTALLATION

This chapter defines the prerequisites for installing the Array and pro vides in struction s to help you complete a
successful installation. Topics addressed in this chapter include:

• “Installation Prerequisites” on page 2-1

• “Planning Your Installation” on page 2-2

• “Installation Workflow” on pa ge 2-13

• “Unpacking the Array” on page 2-13

• “Installing Your Wireless LAN Array” on page 2-14

• “Powering Up the Wireless LAN Array” on page 2-21

• “Establishing Communication with the Array” on page 2-22

• “Performing the Express Setup Procedure” on page 2-23

• “Installing the WFX-3900 Wall Mount Assembly” on page 2-26

INSTALLATI ON PREREQUISITES

Your Array deployment requires hardware and services in the host wired/wireless network, including:

• Dedicated AC power outlet – Unless you are using the Remote DC Power System (WFX-3100) with the DC
version of the Array, you need a dedicated power outlet to supply AC power to each unit deployed at the site. If
you are using the optional WFX-3100, then DC power is supplied to all units and only one AC outlet is required
for the WFX-3100.

• Ethernet port (read notes) – You need at least one 10/100/1000 BaseT port to est ablish wired Gigabit Ethernet
connectivity (via the product’s Gigabit 1 or Gigabit 2 port) and one 10/100 BaseT port (if desired) for product
management.

IMPORTANT

!

• Secure Shell (SSH) utilit y – To establish secure remote command line access to the Array, you need a Se cure
Shell (SSH) utility, such as PuTTY.

• Secure Web browser – Either Internet Explorer (version 6.0 or higher), Netscape Navigator (version 7.0 or
higher), or Mozilla Firefox (version 1.01 or higher) and it must be available on the same subnet as the Array. A
secure Web browser is required for Web-based management of the Array.

• Serial connection capability – To connect directly to the console port on the Array, your co mputer must be
equipped with a male 9-pin serial port and terminal emulation software (for example, HyperTerminal). Use the
following settings (Table 2-1) when establishing a seri al connection:

The Array’s Ethernet ports should be plugged into an Ethernet switch, not an Ethernet hub; if a
hub is used, we recommend you connect only one Ethernet port.

The Gigabit1 Ethernet interface is the primary port for both data and management traffic. If a
single Ethernet connection is used, it must be connected to the Gigabit1 Ethernet interface.

The 10/100 Ethernet Port can be used for managing the Array, and will only bridge manage me nt
traffic. See also, “Port Failover Protection” on page 2-10.

Optional Network Components

The following network components are optional.

• DHCP server – To distribute IP addresses and ancillary information to your Array.

• Wireless Management System (WFX-3300) – The optional WFX-3300 offers powerful management features
for small or large Array deployments.

• Remote DC Power System (WFX-3100) – The optional WFX-3100 provides distributed DC power to multiple
Arrays, eliminating the need to run dedicated AC power to each unit and facilitating backup power when con­nected via a UPS.

• External RADIUS server – Although your Array comes with an embedded RADIUS server, for 802.1x authenti­cation in large deployments you may want to add an external RADIUS server.

Client Requirements

The Array should only be used with Wi-Fi certified client devices.

PLANNING YOUR INSTALLATION

This section provides guidelines and examples to help you plan your Array deployment to achieve the best overall
coverage and performance. We recommend you conduct a site survey to determine the best location and settings
for each Array you install.

General Deployment Considerations

The Array’s unique multi-radio architecture generate s 360 degree s of sectored high-gain 802.11a/b/g coverage that
provides extended range. However, the number, thickness and location of walls, ceilings or other objects that th e
wireless signals must pass through may affect the range. Typical ranges vary depending on the types of materials
and background RF (radio frequency) noise at your location. To maximize wireless range, fo llo w these basic
guidelines:

1. Keep the number of walls and ceilings between the Array and your receiving devices to a minimum—each

wall or ceiling can reduce the wireless range from between 3 and 90 feet (1 to 30 meters). Position your
devices so that the number of walls or ceilings is minimized.

2. Be aware of the direct line between each device. For example, a wall that is 1.5 feet thick (half a meter) at

90° is actually almost 3 feet thick (or 1 mete r) when viewe d at a 4 5° angle. At an acute 2° degr ee angle the
same wall is over 42 feet (or 14 meters) thick! For best reception, try to ensure that your wireless devices
are positioned so that signals will travel straight through a wall or ceiling.

Figure 2-1. Wall Thickness Considerations

3. Building materials can make all the difference. For example, solid metal doors or aluminum wall studs may

adversely effect wireless signals. Try to position wireless client devices so that the signal passes through
drywall (between studs) or open doorways and not other materials.

Coverage and Capacity Planning

This section considers coverage and capacity for your deployment(s), including placement o ptions, RF patterns and
cell sizes, area calculations, roaming considerations, and channel allocations.

Placement

Use the following guidelines when considering placement options:

1. The best placement option for the Array is ceiling-mounted within an open plan environment (cubicles rather

than fixed walls).

2. Keep the Array away from electrical device s or appliances that generate RF noise. Because the Array is

generally mounted on ceilings, be aware of its position relative to lighting (especially fluorescent lighting)—
we recommend maintaining a distance of at least 3 to 6 feet (or 1 to 2 meters).

3. If using multiple Arrays at the same location, we recommend maintaining a distance of at least 100 feet

between units.

RF Patterns

The Array allows you to control—automatically or manually—the pattern of wireless coverage that best suits your
deployment needs. You can choose to operate with full coverage, half coverage, or custom coverage (by enabling
or disabling individual sectors).

Full (Normal) Coverage

In normal operation (see Figure 2-3), the Array provides a full 360 degrees of coverage.

Figure 2-3. Full (Normal) Coverage

Half Coverage

If installing a unit close to an exterior wall, you can deactivate half of the radios to preve nt red unda nt sign als fr om
“bleeding” beyond the wall and extending service into public areas. The same principle applies if you want to restrict
service to an adjacent room within the site.
