The AIRNET 54Mb Outdoor AP/Bridge series is a high-performance Access Point
and Bridge designed for enterprises and outdoor users. It is compatible with IEEE
802.11a/b/g and supports high-speed data transmission up to 54Mb. Housed in
a waterproof casing, AIRNET 54Mb Outdoor AP/Bridge series is designed to
withstand any extreme climatic conditions, making it the ideal solution for
outdoor applications.
The AIRNET 54Mb Outdoor AP/Bridge series has the ability to operate in 7
different modes and can be used in a wide variety of wireless applications like
Point-to-Point, Point-to-Multipoint, Wireless ISP, Hot Spot and Mesh Network
applications. The integrated WDS (Wireless Distribution System) feature creates
a virtually larger wireless network infrastructure by linking up other access points.
Perfect for applications requiring high bandwidth at a fraction of the cost of
T1/E1 leased-line, with the additional advantage of zero monthly recurring cost
from the service carrier. Typical usages include bridging satellite offices,
corporate LANs, school campus, as well as wireless Internet services, at
distances up to 25 miles or 40 Km (using 1 watt amplifier). The Airnet 54Mb
Outdoor Bridge High Power also represents the perfect solution for bridging
networks that are impossible to connect using wired alternatives, including
networks separated by difficult terrains, railroads, or bodies of water.
The AIRNET 54Mb Outdoor AP/Bridge series is based in Atheros eXtended Range
(XR) chipset and provides powerful features such as High Power, higher
throughput, Long Range Parameter Settings, high security 64/128/152 WEP and
WPA2, DHCP Server, Spanning Tree Protocol, Web-based Configuration and
QOS feature which allows media files to be delivered over the network more
efficiently.
Designed for outdoor use, the AIRNET 54Mb Outdoor AP/Bridge series is able to
draw power through Cat-5 Ethernet cable from our DC injector. This ensures
that power is available wherever you need it, without the need of expensive
electrical work often associated with outdoor installations.

The access point is versatile in the sense that it may operate in seven different
types of modes: Access Point Mode, Client Mode, Point to Point, Point to
Multiple Point, Wireless Routing Client , Gateway and Wireless Adapter.
This section presents a brief outline of the different network applications that
can be accommodated through the different modes of the access point.

This is the default mode of your access point. The Access Point mode enables
you to bridge wireless clients to access the wired network infrastructure and to
communicate with each other.
In the example above, the wireless users will be able to access the file server
connected to the switch through the access point in Access Point mode.

In Access Point Client mode, the access point acts as a wireless client that can
operate wirelessly with another access point to perform bridging between two
Fast Ethernet networks. The Access Point client cannot communicate directly
with any other wireless device.
In the example above, the workgroup PCs will be able to access the PCs
connected to the access point in Access Point Client mode.

In Point to Point mode, the access point allows point-to-point communication
between different buildings. It enables you to bridge wireless clients that are
miles or kilometers apart while unifying the networks.
In the example above, you may configure two access points (AP) to perform
transparent bridging between two buildings

In Point to Multiple Point mode, this mode is similar to that of the Point to Point
mode. But the access point located at one facility is able to connect to up to 8
access points (AP) installed in any direction from that facility.
The above illustration describes how this mode operates.

An application of this mode would be for the Ethernet port of the Wireless
Routing Client to be used for connection with other devices on the network
while access to the Internet would be achieved through wireless
communication with wireless ISP.

Or put it more simply, Broadband Internet sharing in a wireless network!
Since the access point supports several types of broadband connections, the
first step in setting up the access point as a Broadband Internet Gateway is to
identify the type of broadband Internet access you are subscribed to.
Static IP address
Use this type of connection if you have subscribed to a fixed IP address or to a
range of fixed IP addresses from your Internet Service Provider.
Dynamic IP address
When powered using this type of connection, the access point requests for an
IP address which will be automatically assigned to it by your Internet Service
Provider.
This type of connection applies for instance, to:
•Singapore Cable Vision subscribers
•@HOME Cable Service users

PPP over Ethernet (PPPoE)
Select this type of connection if you are using ADSL services in a country utilising
standard PPP over Ethernet for authentication.
For instance:
If you are in Germany which uses T-1 connection or
If you are using SingNet Broadband or Pacific Internet Broadband in Singapore.
PPTP
Select this type of connection if you are using ADSL services in a country utilising
PPTP connection and authentication.

Similarly to the Access Point Client mode, the access point used in this mode, is
able to communicate wirelessly with another access point to perform
transparent bridging between two networks.
However here, the Wireless Adapter connects a single wired workstation only.
No client software or drivers are required while using this mode.

• Do not work on the system or connect or disconnect cables during periods of
lightning activity.
• Do not locate the antenna near overhead power lines or other electric light
or power circuits, or where it can come into contact with such circuits. When
installing the antenna, take extreme care not to come into contact with such
circuits, as they may cause serious injury or death.
• Only trained and qualified personnel should be allowed to install, replace, or
service this equipment.
• To meet regulatory restrictions, the radio and the external antenna must be
professionally installed. The network administrator or other IT professional
responsible for installing and configuring the unit is a suitable professional
installer. Following installation, access to the unit should be password protected
by the network administrator to maintain regulatory compliance.
•The outdoor access point and PoE injector can be damaged by incorrect
power application. Read and carefully follow the installation instructions before
connecting the system to its power source.

Before starting, please verify that the following is available:
•CAT5/5e or FTP Outdoor Ethernet cable (from the Outdoor AP to PoE Injector)
•At least one computer is installed with a Web browser and a wired or wireless
network interface adapter
•TCP/IP protocol is installed and IP address parameters are properly
configured on all your network’s nodes
Important!
• Configure and verify the outdoor access point operations first before you
mount the unit in a remote location.
• You may need to install a lightning arrestor to protect your outdoor Access
Point from the lightning.
• For choosing the best location for your outdoor access point choose an
elevated location where trees, buildings and large steel structures will not
obstruct the antenna signals and which offers maximum line-of-sight
propagation with the users.
• Select an appropriate antenna to improve range and/or coverage and
the access point also lets you fine-tune parameters such as the transmit
power to achieve the best results.

The diagram below shows the overall setup of Outdoor Access Point.

Hardware Installation

S
St te ep p 1 1: :
Connect your UTP or FTP Outdoor cat.5 Ethernet cable with waterproof
connector to the RJ-45 connector on the outdoor access point. Then
connect the other end of the cable to the PoE injector.
For the Netkrom PoE, the recommended length of the RJ45 Category 5 cable
is up to 150 feet or 50 meters.
1.- Remove the thin enclosure nut
from the feedthru assembly. This
can be discarded. Loosen the
compression nut completely
2.- Insert the RJ45 connector thru
the feedthru assembly
3.- Tighten the compression nut
loosely to the feedthru assembly
4.- Screw the entire feedthru
assembly into the RJ45-ECS housing
which is already mounted in the
enclosure. There should be a rubber
gasket between the two
assemblies. Tighten the feedthru
assembly to create a seal.

5.- The final step is to tighten the
compression nut until the gaskets
are tight around the Cat5 cable.
Always push the cable toward the
connector while tightening to
ensure good strain relief of cable to
connector.

point.
Connect the RJ45 Ethernet cable attached to the Netkrom PoE Injector to a
switch or PC you will use to configure the access point.
