WAB–2000 Chapter 1: Introduction
Chapter 1: Introduction
This manual covers the installation and operation of the Level One's WAB–2000 108Mbps Mesh
AP/Bridge. The WAB–2000 is a ruggedized access point/bridge which is intended for use in industrial
and external environments. It accommodates 802.11a/b/g, 802.11g Super, and 802.11a Turbo WLAN
access and uses Power over Ethernet (PoE) access to the Ethernet WAN to eliminate the need for
internal access point power supply units (AC-DC converters) and 110-220V cabling installations. The
wireless LANs can include mobile devices such as handheld Personal Data Assistants (PDAs), mobile
web pads, and wireless laptops.
If encryption is desired for the WLAN, you can select None, Static WEP, or WPA. WPA uses
TKIP or AES-CCMP so you can employ legacy client WEP cards and still secure the wireless band.
The WAB–2000 incorporates Power over Ethernet. The PoE interface on the WAB–2000 is
compatible with commercial vendor “injected power” hub units.
The WAB–2000 includes AES cryptographic modules for wireless encryption and HTTPS/TLS, for
secure web communication. In addition, it contains the capability to use the traditional WEP algorithm,
either as static WEP or managed under WPA. The WAB–2000 has an Ethernet WAN interface for
communication to the wired LAN backbone, Ethernet LAN local port for purposes of initial setup and
configuration, and two wireless AP antennas for communicating on the 802.11a/b/g frequencies. Further,
it has the capability for use of an external (remote) antenna, for bridging, using the 802.11b/g Mixed,
802.11a, 802.11g Super, 802.11a Turbo frequencies.
The WAB-2000 supports Auto-forming wireless bridging (AWB) - with a maximum number of
allowable bridges (the default is 40). When the wireless bridge is in auto-forming mode, the wireless
bridge sniffs for beacons from other wireless bridges and identifies APs that match a policy such as
SSID and channel. Instead of simply adding the APs with the same SSID/channel to the network, a
three-way association handshake is performed in order to control network access.
Basic Features
The WAB–2000 is housed in a sturdy case, which is not meant to be opened except by an
authorized technician for maintenance or repair. If you wish to reset to factory settings, use the reset
function available through the GUI-based management module or press and hold the reset button on the
front of the unit for 10 seconds.
The WAB–2000 is wall-mountable.
It has the following features:
1
WAB–2000 Chapter 1: Introduction
• Ethernet uplink WAN port/Local Ethernet LAN port (for configuration only)
• Wireless AP with operating range of 2000+ feet
• Auto-forming wireless bridging (AWB) ,up to 40 nodes.
• Power over Ethernet (PoE)
• Above average temperature range for extreme environments (with TEC option)
• HTTPS/TLS secure Web
• DHCP client
• Bandwidth control
• Adjustable Radio Power
• MAC address filtering
• Load Balancing
• Rogue AP Detection
The following security modules have been implemented in the WAB–2000.
• AES (128 bit) for Bridge
• WEP (64, 128, and 152 bit) for AP
• WPA (pre-share key and TKIP/AES-CCMP) for AP
• 802.11i/WPA2 (128 bit) for AP
Wireless Basics
Wireless networking uses electromagnetic radio frequency waves to transmit and receive data.
Communication occurs by establishing radio links between the wireless access point and devices
configured to be part of the WLAN.
For wireless devices to communicate with the WAB–2000 , they must meet the following
conditions:
• The wireless device and wireless access point must have been configured to recognize each other
using the SSID (a unique ID assigned in setup so that the wireless device is seen to be part of the
network by the WAB–2000 );
• Encryption and authentication capabilities and types enabled must conform; and
• If MAC filtering is used, the WAB–2000 must be configured to allow the wireless device’s MAC
address to associate (communicate) with the WAB–2000 wireless interface.

WAB–2000 Chapter 1: Introduction
802.11b
The IEEE 802.11b standard ratified by IEEE, establishes a stable standard for compatibility. A user
with an 802.11b product can use any brand of access point with any other brand of client hardware that
is built to the 802.11b standard for basic interconnection. 802.11b devices provide 11 Mbps transmission
(with a fallback to 5.5, 2 and 1 Mbps depending on signal strength) in the 2.4 GHz band.
802.11g
Because 802.11g is backwards-compatible with 802.11b, it is a popular component in LAN
construction. 802.11g broadens 802.11b’s data rates to 54 Mbps within the 2.4 GHz band using OFDM
(orthogonal frequency division multiplexing) technology.
802.11a
The IEEE 802.11a standard is an extension to 802.11 that applies to wireless LANs and provides up to 54 Mbps in the 5GHz band.
802.11a uses an orthogonal frequency division multiplexing encoding scheme rather than FHSS or DSSS.
802.11b/g Mixed
802.11b/g combines 802.11b and 802.11g data rates to offer a broader range. In this mode, all
transmissions will be at the highest data rate available.
802.11 Super G and Turbo A
802.11 Super G and 802.11 Turbo A technologies provide double speed and throughput of standard
11G/11A. Higher throughput is necessary for a variety of functions such as: streaming media (video,
DVD, MPEG), VoIP, etc., or for providing multiple users on a single WLAN with optimal speeds
despite network demand. 108 Mbps is the maximum link speed available and the typical MAXIMUM
end-user throughput ranges from approximately 40 Mbps to 60+ Mbps.
NOTE: Super G’s channel bonding feature can significantly degrade the performance of
neighboring 2.4GHz WLANs that don’t use Super G, because there isn’t enough room in the 2.4GHz
wireless LAN spectrum. Moreover, Super G doesn’t check to see if 11b or 11g standards-compliant
devices are in range before using its non-standard techniques.
NOTE: Due to the frequency regulation in Europe, Turbo A spectrums are reserved and not
available for the general users. Therefore European users may find that all the Turbo A functions
mentioned in this manual are not available.

Network Conguration
The WAB–2000 is an access point with bridging setup capability:
• Access point/Gateway plus:
• Wireless bridging with choice of:
- Point-to-point setup
- Point-to-multipoint setup
- Repeater setup
Bridging actually has more choices, but the above choices are popular
and are discussed later in this user guide (Chapter 4).
Access Point Congurations
When a WAB–2000 is used as an access point, IP addresses for wireless devices are typically assigned by the wired network’s DHCP server.
The wired LAN’s DHCP server assigns addresses dynamically, and the
AP virtually connects wireless users to the host wired network. All wireless devices connected to the AP are congured on the same subnetwork
as the wired network interface and can be accessed by devices on the
wired network.
Possible AP Topologies
1. An access point can be used as a stand-alone AP without any
connection to a wired network. In this conguration, it simply
provides a stand-alone wireless network for a group of wireless
devices.
4 29000156-001 A
WAB–2000 Wireless Access Point Chapter 1: Introduction
2. There can be multiple APs connected to an existing Ethernet
network to bridge between the wired and wireless environments.
Each AP can operate independently of the other APs on the LAN.
Multiple APs can coexist as separate individual networks at the
same site with a different network ID (SSID).
3. The last and most prevalent use is multiple APs connected to a
wired network and operating off that network’s DHCP server to
provide a wider coverage area for wireless devices, enabling the
devices to “roam” freely about the entire site. The APs have to use
the same SSID. This is the topology of choice today.
Bridging
The wireless bridging function in the WAB–2000 allows use as a
bridge, in a number of alternate congurations, including the following
popular congurations:
• Point-to-point bridging of 2 Ethernet Links;
• Point-to-multipoint bridging of several Ethernet links;
• Repeater mode (wireless client to wireless bridge.)

WAB–2000 Wireless Access Point Chapter 1: Introduction
29000156-001 A 7
Data Encryption and Security
The WAB–2000 Wireless Access Point includes advanced wireless security features. Over the AP band, you have a choice of no security, Static
WEP, or WPA. Some level of security is suggested. Static WEP gives you
a choice of 64-bit, 128-bit, or 152-bit encryption. WPA includes the option
of using a WPA pre-shared key or, for the enterprise that has a Radius
Server installed, conguration to use the Radius Server for key management with either TKIP or AES-CCMP. Bridging encryption is established
between WAB–2000’s and includes use of AES-ECB 128-bit encryption
(approved by the National Institute of Standards and Technology (NIST)
for U.S. Government and DoD agencies).
SSID
The Service Set ID (SSID) is a string used to dene a common roaming domain among multiple wireless access points. Different SSIDs on
access points can enable overlapping wireless networks. The SSID can
act as a basic password without which the client cannot connect to the
network. However, this is easily overridden by allowing the wireless AP
to broadcast the SSID, which means any client can associate with the AP.
SSID broadcasting can be disabled in the WAB–2000 setup menus.
WEP
WEP is an older encryption standard but is preferable to no encryption. If the WAB–2000 is congured with WEP encryption, it is compatible
with any 802.11b PC Card congured for WEP.
WPA with TKIP/ AES-CCMP(WPA2)
WPA, an interim standard developed by the WiFi Alliance, combines
several technologies. It includes the use of the 802.1x standard and the
Extensible Authentication Protocol (EAP). In addition, it uses, for encryption, the Temporal Key Integrity Protocol (TKIP) and WEP 128-bit encryption keys. Finally, a message integrity check (MIC) is used to prevent an
attacker from capturing and altering or forging data packets. In addition,
it can employ a form of AES called AES-CCMP.
WPA is a subset of the 802.11i standard and is expected to maintain
forward compatibility.
6 29000156-001 A
WAB–2000 Wireless Access Point Chapter 1: Introduction
AES
The Advanced Encryption Standard (AES) was selected by National
Institute of Standards and Technology (NIST) in October 2000 as an upgrade from the previous DES standard. AES uses a 128-bit block cipher
algorithm and encryption technique for protecting computerized information.
The WAB–2000 uses AES for the bridging channel.
MAC Address Filtering
The MAC address, short for Media Access Control address, is a hardware address that uniquely identies each node of a network. In IEEE 802
networks, the Data Link Control (DLC) layer of the OSI Reference Model
is divided into two sub-layers: the Logical Link Control (LLC) layer and the
Media Access Control (MAC) layer. The MAC layer interfaces directly with
the network media. Consequently, each type of network media requires a
unique MAC address.
Authentication is the process of proving a client identity. The
WAB–2000 access points, if set up to use MAC address ltering, detect
an attempt to connect by a client and compare the client’s MAC address
to those on a predened MAC address lter list. Only client addresses
found on the list are allowed to associate. MAC addresses are pre-assigned by the manufacturer for each wireless card.
DHCP Server
The DHCP function is accessible only from the local LAN port to be
used for initial conguration.
Operator Authentication and Management
Authentication mechanisms are used to authenticate an operator accessing the device and to verify that the operator is authorized to assume
the requested role and perform services within that role.
Access to the management screens for the WAB–2000 requires knowledge of the assigned operator ID and Password. The Factory defaults are:
• ID: crypto
• Password: ofcer
The Crypto Ofcer initially installs and congures the WAB–2000
after which the password should be changed from the default password.
The ID and Password are case sensitive.

WAB–2000 Chapter 2: Hardware Installation
Chapter 2: Hardware Installation
Preparation for Use
The WAB–2000 Wireless Access Point requires physical mounting and installation on the site,
following a prescribed placement design to ensure optimum operation and roaming.
FCC Regulations require that the WAB–2000 be professionally installed by an installer
certified by the National Association of Radio and Telecommunications Engineers or equivalent
institution.
The WAB–2000 operates with Power over Ethernet (PoE) which requires the installation of a
separate Power injector which “injects” DC current into the Cat5 cable. There are two versions of the
WAB–2000 available, the standard version with a temperature range of -5 degrees C to +50 degrees C,
and there is the extended temperature range product with a range of -30 degrees C to +70 degrees C. The
latter version of the product employs ThermoElectric Cooler (TEC) technology to extend the product
into the higher temperature environment.
The TEC Technology requires power to transfer the heat. Unfortunately, this raises the electric
current requirement to 25 watts, beyond the 802.3af specification of 15.4 watts. To ensure that the
WAB–2000 with TEC option is provided with the power it requires, an extended range PoE power
injector enclosed within the package is required.
The WAB–2000 package includes the following items:
• The WAB–2000 Wireless Access Point
• 2 attachable 5dBi omni-directional antennas
• 2 meter LAN Ethernet cable (RJ-45 to RJ-45)
• Documentation as PDF files (on CD-ROM)
• Registration and Warranty cards
• Power Injector, POE, 50W
• 3 meter antenna extension cable
• Outdoor Protection Kit

WAB–2000 Wireless Access Point Chapter 2: Hardware Installation
WAB–2000 Wireless Access Point Chapter 2: Hardware Installation
29000155-001 A 13
The bridge antenna port is used when conguring the unit to be used
as a bridge. The port uses an omni-directional antenna.
The WAB–2000 can be mounted outdoors on a high post to achieve
the best bridge result. If mounted outdoors, the outdoor protection kit
must be used to prevent lightning damage.
To comply with FCC RF exposure compliance requirements, the
antennas used with the WAB–2000 must be installed with a mini-
mum separation distance of 20 cm from all persons, and must
not be co-located or operated in conjunction with any other antenna or
transmitter. Installation should be accomplished using the authorized
cables and/or connectors provided with the device or available from the
manufacturer/distributor for use with this device. Changes or modications not expressly approved by the manufacturer or party responsible for
this FCC compliance could void the user’s authority to operate the equipment.
Installation Instructions
The WAB–2000 is intended to be installed as part of a complete wire-
less design solution.
This manual deals only with the WAB–2000 device. The purpose of
this chapter is the description of the device and its identiable parts so
that the user is sufciently familiar to interact with the physical unit. Preliminary setup information provided below is intended for information
and instruction of the wireless LAN system administration personnel.
It is intended that the user not open the unit. Any maintenance required is limited to the external enclosure surface, cable connections, and
to the management software (as described in chapter three through ve)
only. A failed unit should be returned to the manufacturer for maintenance.
Minimum System and Component Requirements
The WAB–2000 is designed to be attached to the wall at appropriate
locations. To complete the conguration, you should have at least the following components:
• PCs with one of the following operating systems installed: Windows NT 4.0, Windows 2000 or Windows XP;
• A Wi-Fi compatible 802.11a/b/g device for each computer that
you wish to wirelessly connect to your wireless network.
• Access to at least one laptop or PC with an Ethernet card and
cable that can be used to complete the initial conguration of the
unit.
• A Web browser program (such as Microsoft Internet Explorer 5.5
or later, or Netscape 6.2 or later) installed on the PC or laptop you
will be using to congure the Access Point.
• TCP/IP Protocol (usually comes installed on any Windows PC.)

29000155-001 A 15
Bridge Transmit Distance
Normally, the bridge need transmit RF signal to another bridge device
at long distance. You may need to calculate the RF link Budget as reference. The equation of RF link budget is:
Fade Margin = received signal – receiver threshold
Where
Received signal = Transmitter power – Transmitter cable loss + Trans-
mitter antenna gain – free space path loss + Receiver antenna gain
– Receiver cable loss
Received threshold = Received sensitivity
Free Space Path Loss
Using below Free Space Loss Formula to calculate free space path loss
Where
LP = free space path loss between antennas
F = frequency in GHz
D = path length in miles
Bridge Antenna Location
When as bridge device, the WAB-2000 may need to be mounted out-
doors on a high place to achieve the best bridge result. The Fresnel zone
and Earth bulge dominate to decide how high that the unit’s Antenna
need be put. The total antenna height equals the width of Fresnel zone
plus the height of earth bulge.
The Fresnel zone is the area around the visual line-of-sight that radio
waves spread out into after they leave the antenna. This area must be
clear or else signal strength will weaken. The rule of thumb is that 60% of
the Fresnel zone must be clear of obstacles. Typically, 20% Fresnel Zone
blockage introduces little signal loss to the link. Beyond 40% blockage,
signal loss will become signicant.
14 29000155-001 A
WAB–2000 Wireless Access Point Chapter 2: Hardware Installation
The equation of the width of Fresnel Zone is:
Where
W = Width of the Fresnel Zone (in feet)
D = Distance between the antennas (in miles)
F = Frequency in GHz
When the transmit distance of RF signal is longer than seven miles,
the curvature of the earth may be a factor and require the antenna put at
higher location. The additional antenna height can be calculated by below
formula:
Where
H = Height of earth bulge (in feet)
D = Distance between antennas (in miles)
Outdoor Protection Kit Installation
If any portion of this assembly, either the WAB–2000 unit or any attached antenna, is to be used outside, the proper Outdoor Protection Kit
must be installed. This kit contains lightning arrestors for each antenna
and the required cabling to connect these items to the common grounding
stud on the WAB–2000 unit.
NOTE: You (the user) are required to ensure that the connection to a
proper earth ground is made by properly certied and authorized personnel and must conform to all applicable codes and regulations. The materials required to connect to a proper ground are dened by local conditions
and must be procured locally to ensure the correct safety environment is
achieved. The cable used to connect to a proper ground must be AWG 10
or heavier. This cable should be kept as short as possible.
! WARNING
Do not attempt to install any outdoor equipment during hazardous conditions such as a
thunderstorm, where lightning could strike the
equipment or installer. Failure to follow this
warning could result in injury or death.

Earth Ground Connection
Attach the earth ground ring terminal to the WAB–2000's grounding
stud. Make sure the ring terminal is against the unit's metal case. The
earth ground ring terminal should be the rst connection on the unit's
grounding stud.
NOTE: The cable used to connect to a proper earth ground must be
AWG 10 or heavier. This cable should be kept as short as possible
Lighnting Arrestor Installation
To install the lightning arrestor option, attach one end of the lightning
arrestor to the WAB–2000's antenna connector. Attach the antenna (or the
antenna cable) to the other end of the lightning arrestor.
Attach the ring terminal from the Lightning Arrestors’ ground cable
to the grounding stud on the WAB–2000 unit. The lightning arrestor's
ring terminal should be attached to the unit after the earth ground ring
terminal is attached.
Perform this same procedure for every antenna installed on the unit.
It is recommended that this Outdoor Protection Kit be replaced every
three years. If the unit is operated in an area subject to intense lightning
activity, it is recommended that the Outdoor Protection Kit be replaced
every year.

Antenna Installation
The WAB–2000 ships with two 5dBi omni-directional antennas. These
antennas should be connected to the AP antenna connectors located on
the rear of the unit.
NOTE: Make sure a lightning arrestor is installed between the unit
and the antenna if any part of this assembly is located outdoors. See the
previous section.
If you are not using the access point function then you do not need
the AP antennas. Make sure during your conguration set up that you go
to the Wireless Access Point—General screen and set the Tx Pwr Mode
to Off (see Chapter 3).
Sealing Antenna Connections
Once all antennas have been installed, the connections should be
sealed to protect them from the exterior harsh environment. Use a self
amalgamating polyisobutylene tape which, over a period of hours, adheres to itself and forms a single amalgamated rubber molding conforming to the shape of the item it is covering. Once the tape is in place for
several hours, it forms a shaped rubber molding that is resistant to water
and most solvents. It remains stable over a wide temperature range and
degrades very slowly in sunlight. If you need to remove the tape after it
has sealed for 30 minutes or more, cut it away with a sharp knife.

The bridge antenna port is located on the front of the WAB–2000. To
obtain the best performance, the bridge antenna should be placed away
from the AP antennas. Use a 1.5 meter low loss antenna cable to connect
a directional antenna to the WAB–2000. The maximum gain for the directional antenna should be 14 dBi.
Mounting Kit Setup
To mount the WAB–2000 outdoors, you should choose a suitable
post to mount the unit high in the air. Use the U-ring, screws and nuts to
attach the mounting plate to the post. Next attach the WAB–2000 to the
mounting plate with screws.
The Indicator Lights
The top panel of the WAB–2000 contains a set of indicator lights (Light
Emitting Diodes or LEDs) that help describe the state of various networking and connection operations.

LED Description
Power The Power indicator LED informs you when the gate-
way is on or off. If this light is on, the gateway is on; if
it is not on, the gateway is off.
WAN This light indicates the state of your connection to the
organization's Ethernet LAN network. When on, the
WAN light indicates that the unit is connected to the
network. When the WAN light is off, the gateway does
not have an active connection to the network.
WLAN1 Activity This light may be steady or blinking and indicates that
information is passing through the AP connection.
WLAN2 Activity This light may be steady or blinking and indicates that
information is passing through the Bridge connection.
WLAN Signal Strength The Strength LED indicator indicates the strength of
the Bridge connection (WLAN2).
1. LED Off: means no connection on the bridge side, or
the signal is very weak
2. LED blinks slowly (every 1 second): means there is a
connection, and the signal quality is poor
3. LED blinks fast: means there is a connection, and the
signal quality is good
4. LED steady on: means there is a connection, and the
signal quality is excellent
