Hardware Description
Ethernet Compatibility
The AI108 wireless bridge can attach directly to 10Base-T/100Base-TX (twisted-pair)
Ethernet LAN segments. These segments must conform to the IEEE 802.3
specification.
The AI108 appears as an Ethernet node and performs a bridging function by moving
packets from the wired LAN in one building to a wired LAN in a different building.
Radio Characteristics
The AI108 wireless bridge employs a radio modulation technique known as Orthogonal
Frequency Division Multiplexing (OFDM), operating in the 5 GHz Unlicensed National
Information Infrastructure (U-NII) band. Data is transmitted over a half-duplex radio
channel at up to 108 Mbps speed.
Antenna Type – Purchase of external antennas is required for this product.
AI108-2-xxx wireless bridges contain N-Type connectors for attaching external
antennas. Available antenna options include a 18.4 dBi patch antenna - maximum
operating range of 1 mile (1.6km) or a 23.9 dBi patch antenna - maximum operating
range of 2.5 miles (4km) under FCC and Industry Canada rules. For international
markets other antennas options (both integrated and external) may be available
based on local regulations. Please contact AIRAYA for additional antenna options.
Enclosure
The molded fiberglass polyester enclosure of the AI108 outdoor unit has been
designed for maximum weatherability and durability in outdoor settings. It is
watertight and meets the NEMA/EEMAC Type 4, 4X, 12, and 13 specification.

AI108 Architecture and Topology
The following diagram illustrates a typical usage scenario of an AI108 wireless bridge
to interconnecting two local area networks.

- 10 -
System Requirements
Before you install the AI108 wireless bridge, be sure you have the following items on-
hand:
• An AC power outlet (100 to 240 V, 50 to 60 Hz) which will supply power to the
indoor units on both sides of the wireless connection
• An outdoor unit mast with a diameter of 1.9 inches (50 mm) to 4.5 inches (115
mm)
• An available RJ-45 (UTP) port on a 10/100Mbps Ethernet hub or switch
• Web browser for software configuration
The AI108 wireless bridge has been designed to withstand normal handling
procedures, but reasonable precautions should be exercised during the installation,
particularly with regard to static discharge.
• Make sure that you are adequately grounded by touching the bare metal
surface on the back of a computer or networking device before installing the
indoor and outdoor units.
• Avoid moving around the work area in order to eliminate static charge buildup.
• If possible, do not work on a carpeted area.

Follow these steps to install the indoor unit:
1. Connect the DATA port to your 10/100 Mbps Ethernet hub or switch using a
straight-through category 5 UTP cable.
2. Connect the power cable to the 12 VDC power socket on the rear panel, and
plug the power adapter into the wall outlet. Warning: Use only the power
adapter supplied with the AI108 wireless bridge in order to prevent damage.
3. You are now ready to apply power to the outdoor unit. Connect the DATA/PWR
port to the outdoor unit using the included Category 5E cable that came
attached to the outdoor unit. The DETECT and 48 V OUT LEDs will light to
indicate that the outdoor unit is connected to your network and receiving
power.

Installing and Aligning the External Antennas
To ensure maximum performance and stability of your wireless connection, it is crucial
that you determine the right locations for the external antennas based on the
following two criteria:
1. Establish a good signal path, ideally with visual line of sight, between the two
end points.
2. Minimize the distance between the two end points.
Pole mast mounting of the external antennas and outdoor units can be accomplished
using the included mounting brackets with full elevation adjustment, as illustrated in
the figure to the right.
Follow these steps to install the outdoor units and external antennas:
1. Attach the outdoor unit to the mast using the two included pole mounting
clamps. Attach the external antennas using the same technique.

- 14 -
2. Align the external antenna horizontally. Loosen the pole mounting clamps just
enough to visually aim the external antenna at the remote end point. Set the
appropriate horizontal angle and tighten the pole mounting clamps so that the
angle is locked in place.
3. Align the external antenna vertically. Loosen the elevation control bolts on the
mounting bracket and point the antenna towards the remote end point.

- 15 -
4. Set the appropriate elevation angle and tighten the bolts so that the angle is
locked in place. The bracket design allows for up to 20°tilt of the antenna.
5. Secure both the cable between the external antenna and the outdoor unit, and
the Category 5E cable between the outdoor unit and the indoor unit to the mast
using UV-rated tie-wraps (4 are included). Note: It is recommended that you
secure the entire cable length to the mast every 10 feet.
6. Repeat steps one through five for the second outdoor unit in the remote
location.
7. If necessary, use the AI108 antenna alignment tool to fine tune your received
signal strength (RSS). Loosen the pole mounting clamps and elevation control
bolts again, and rotate the antenna slowly around its mast. As the antenna
slews towards the remote device, the RSS indicator will show an increase. Keep
rotating the unit until the maximum strength signal has been obtained, then
tighten all fasteners and bolts to secure the assembly.
8. Repeat step seven for the second external antenna.

Software Configuration
The network and security parameters of your wireless bridge pair are configured by
using the built-in AI108 web server. The AI108 web server greatly simplifies the
configuration process by allowing the user to access all parameters and settings
through a single, consistent user interface.
Note: For added security, this configuration utility is only accessible within two
minutes of power-up. This utility is not available during normal bridge operation.
Getting Started
The factory default IP address and port number of the AI108 wireless bridge is
192.168.1.70:8080. Type that string into the address field of your browser and press
the Return key to load the AI108 web server. You will be prompted for a user name
and password at that point. Note: See section Logging in to the AI108 Web Server
below for information on default settings.
Logging in to the AI108 Web Server
The AI108 requires you to enter a user name and password to gain access to the
configuration utility. The default value for the fields User Name and Password is
“Airaya”.

- 17 -
Once you are logged in to the AI108 web server, you will have access to all
configuration options available in the AI108. The web interface is organized into tabs
that facilitate different categories of parameters and functions, including Current
Settings, Link Setup, Link Security, System Password, Download Updates, and Help.
The first screen you see is the Current Settings tab.
Current Settings Tab
The Current Settings tab allows you to view, but not change, the system information
and current setup of your AI108 unit.

- 18 -
The following parameters can be viewed from the Current Settings tab:
• Software Version - Current software (firmware) version installed and
running on the bridge you are working with. This value is formatted as a
date code.
• Hardware Version - Current hardware revision of the local bridge.
• IP Address - Current IP address of the local bridge you are working with.
• Subnet Mask - Current subnet mask of the local bridge you are working
with.
• Gateway Address - Current gateway address of the local bridge you are
working with.
For a detailed description of the IP Address, Subnet Mask, and Gateway Address
parameters, please refer to section Link Setup Tab.
• Local Bridge MAC Address - MAC address of the local bridge you are
working with.
• Remote Bridge MAC Address - MAC address of the remote bridge this
local bridge is currently paired with.
For additional information on the Bridge MAC Address parameters, please refer
to MAC Address Authentication in section Link Setup Tab.
• Active Encryption Key - WEP key currently providing data encryption over
the wireless link.
• Active Encryption Key Length -Length of the encryption key currently
being utilized on this pair of bridges.
For a detailed description of the WEP protocol and related parameters, please
refer to section Link Security Tab.

- 19 -
Link Setup Tab
The Link Setup screen is used to enter parameters related to the configuration of your
network, radio channel, and data rate of the AI108.
The following parameters can be accessed and modified from the Link Setup tab:
• IP Address - The IP address for each AI108 wireless bridge must be unique, so
please check with the network administrator for the correct IP address to be
assigned to this device. The format of an IP address is a 32-bit numeric address
written as four numbers separated by periods. Each number can be zero to 255.
Note: The updated IP address will replace the default IP address listed in the
Getting Started section. After activating your changes with the Restart or Start
Bridge command, you can access the AI108 web interface by specifying the
updated IP address and port number.

- 20 -
• Subnet Mask - The subnet mask allows networking software to determine which
parts of the IP address specify the network address and which parts specify the
host address. If your device is using the wrong subnet mask for the network to
which you are attached, it will therefore not be able to communicate with all
users on that network. The factory programmed subnet mask of the AI108
wireless bridge is 255.255.255.0.
Gateway Address - IP packets destined for other subnets are automatically sent to the
default gateway, which routes the traffic to the correct network. The gateway address
must be specified following the same convention as the IP address.
Antenna Alignment Tool - The antenna alignment tool displays your current
connection status based on received signal strength (RSS). The RSS indicator is a
useful diagnostic tool for you to test the transmission quality between the local and
remote AI108 bridge unit and to optimize antenna alignment. Please refer to section
Installing and Aligning the Outdoor Units for detailed instructions on antenna
alignment.
Note: Remember to save your new configuration settings before selecting another tab
by pressing the Submit button. If you are finished making changes to the local bridge
configuration, press the Restart button to save the new configuration settings and
reboot the local bridge, activating all new settings. You can also use the Start Bridge
button to activate the new settings and immediately put the unit in bridging mode,
without re-entering the configuration utility.
Note: If settings are modified inadvertently, the Restore System Defaults button can
be used to return to the factory default settings of all networking, radio, and security
parameters. All modified data will be lost.
