Product Description
The AT-WL2411 Access Point forwards data from wireless end devices to
the wired Ethernet network. The AT-WL2411 can be used as an access
point or as a point-to-point bridge. An access point is connected to a
wired network and provides network access for wireless end devices. A
point-to-point bridge connects two wired LANs and is often used to
provide wireless communications in locations where running cable is
difficult, such as across roads or between buildings. The AT-WL2411
accommodates one 802.11b radio. The AT-WL2411 is ideal for use in
networks that do not need mixed radios or when configured as a station
at the remote end of a wireless hop to a secondary LAN.
Summary of Features
❑ Supports IEEE 802.11b radios
❑ Installed 802.11b radio is Wi-Fi certified
❑ 10 Mbps Ethernet port with an RJ-45 connector
❑ Status LEDs
❑ Serial port for initial configuration and management
❑ Version 1.80 configuration firmware
❑ 5 V DC external power supply input port
❑ Configuration via serial connection, Web browser, and Telnet
❑ Can be used a DHCP server or client
❑ Can support 256 wireless end devices

An external AC/DC power adapter is included with the access point. The
power adapter supplies 5V DC to the access point. The power required
for the access point is 5V DC, 2.0 A.

Product Description
Network Configurations
The AT-WL2411 Access Point supports a variety of network
configurations that are explained in this section.
A Simple
Wireless
Network
You can use the access point to extend your existing Ethernet network
to include wireless end devices. The access point connects directly to
your wired network and the end devices form a network that functions
as a wireless extension of the wired LAN.
In a simple wireless network, a single access point on the wired network
serves as a transparent bridge between the wired network and end
devices. The end devices communicate exclusively with devices on the
wired network; they do not communicate with other end devices. This
kind of simple wireless network is illustrated in Figure 4.

AT-WL2411 Version 1.80 Installation and User’s Guide
Using Multiple
APs and
Roaming End
Devices
For larger or more complex environments, you can install multiple
access points so end devices can roam from one access point to another.
Multiple access points establish coverage areas or cells similar to those
of a cellular telephone network. End devices can connect with any
access point that is within range and belongs to the same network.
With the access point multichannel architecture, you can have more
than one access point within the same cell area to increase throughput.
In addition, overlapping radio coverage cells offer redundancy for critical
applications so that coverage is not lost if a single access point or radio
fails. This kind of network is illustrated in Figure 5.

Product Description
Using APs to
Create a Point-
to Point Bridge
You can use access points to create a wireless or point-to-point bridge
between two LANs. You can have a access point wired to a network in
one building and have a second access point wired to a network in
another building. Wired clients in both buildings can then communicate
with each other over the wireless bridge created by the access points.
This configuration is useful in a campus environment where pavement
or other objects prevent installation of a wired link. For information
about configuring access points for point-to-point bridging, see
Configuring Wireless Hops. Figure 6 illustrates a network with a point-topoint bridge.

Installation Safety Precautions
Please review the following safety precautions before you begin to
install the access point. Refer to Translated Electrical Safety and Emission
Information on page 221 for statements in your language.
Warning
Power to the access point must be sourced only from the
adapter:
Europe—EC
Use TÜV licensed AC adapter of 5 V DC, min 2.0 A.
Other Countries
Use a Safety Agency Approved AC adapter of 5 V DC, min 2.0 A. 4
Warning
Power cord is used as a disconnection device: To de-energize
equipment, disconnect the power cord. 5
Warning
Lightning Danger: Do not work on this equipment or cables
during periods of lightning activity. 6
Caution
Air vents: The air vents must not be blocked on the unit and must
have free access to the room’s ambient air for cooling. 7
Caution
Operating Temperature: This product is designed for a maximum
ambient temperature of 65°C. 8
Caution
All Countries: Install this product in accordance with local and
national electric codes. 9
26
Selecting a Site for the Access Point
Allied Telesyn recommends that you have Allied Telesyn or other
certified providers conduct a site survey to determine the ideal locations
for all of your network components. A proper site survey requires special
equipment and training.
Observe the following requirements when choosing a site for your
access point:
❑ If you are installing the access point on a table, be sure that the
table is level and secure.
❑ The power outlet for the access point should be located near the
unit and should be easily accessible.
❑ The site should provide for easy access to the ports on the access
point. This will make it easy for you to connect and disconnect
cables.
AT-WL2411 Version 1.80 Installation and User’s Guide
❑ Try to position the access point so that its LEDs are visible. The
LEDs are useful for troubleshooting.
❑ To allow proper cooling of the access point, air flow around the
unit and through its vents on the side and rear should not be
restricted.
❑ Do not place objects on top of the access point.
❑ Do not expose the access point to moisture or water.
❑ Make sure that the site is a dust-free environment.
❑ You should use dedicated power circuits or power conditioners to
supply reliable electrical power to the access point.
❑ Locate access points centrally within areas requiring coverage.
❑ Overlap access point coverage areas to avoid coverage holes.
❑ Access points configured for the frequency in the same coverage
area may interfere with each other and decrease throughput. You
can reduce the chance of interference by configuring your access
points so they are configured 5 channels apart, such as Channels
1, 6, and 11.
❑ Install wired LAN cabling within de vice limit and cable length
limitations.
27
Installation
❑ Microwave ovens operate in the same frequency band as the
802.11b HR radio; therefore, if you use a microwave within range
of your Allied Telesyn RF network, you may notice network
performance degradation. Both your microwave and your RF
network will continue to function, but you may want to consider
relocating your microwave out of range of your access point.
The access point features an advanced configuration
parameter for the 802.11b HR radio called microwave oven
robustness. You can enable this parameter to minimize
potential interference between your microwave oven and
your RF network.

Installing the Access Point
You can install the AT-WL2411 horizontally on a desk or counter, or you
can install it vertically to a wall using the wall bracket that ships with it.
An optional cubicle bracket is also available for mounting the
AT-WL2411 on a cubicle wall.
Wall-mounting the AT-WL2411
To install the mounting bracket and AT-WL2411 on a sturdy surface in
accordance with local building codes, you need the following tools and
materials:
❑ Two #5 or M3 screws.
❑ Drill and drill bit appropriate for the mounting screws
❑ Screwdriver
To wall-mount the AT-WL2411, perform the following procedure:
1. Using the mounting bracket as a template, mark the location of the
mounting holes on the wall.
2. Drill the mounting holes.
3. Position the wall-mounting bracket on the wall and using the M3
screws (not provided), secure the bracket to the wall, as shown in
Figure 7.
