2.2 Procedure of Hardware Installation
Figure 2-6
1. Decide how to place Bridge
Because this product is a radio device works in the 2.4 GHz frequency
range. For optimum utilization, installing this product away from microwave
ovens or other devices, operating in the 2.4 GHz frequency range, which can
cause signal interference. Otherwise, install this product’s antenna in an area
where the trees, buildings and large steel structures such as file cabinet and
bookshelves do not obstruct the signal to and from the antenna. In conclusion,
the antenna should be located in the higher direct line-of-sight space.
2. Lightning Protection
Radio transmitters, receivers and RF cables require protection when
attacked by lightning strikes.
The surge protectors contain fast response gas filled arrestors to provide
low let through voltage for fast rise time transients. The device is configured
to minimize circuit capacitance and the performance can be assured up to
2GHz. Standard models provide protection for receivers and transmitters up to
a 1KW power level.
Installing this device in outdoor may be subject to lightning strikes. To
properly protect your equipment, you should install the lightning arrestor to
10
prevent an electrical surge from traveling through the antenna cable and into
the building. Lightning protection for a building is more forgiving than
protection of electrical devices. A building can withstand up to 100,000 volts,
but electrical equipment may be damaged by just a few volts.
Direct earth grounding of the antenna and the Lightning Protector is
necessary to protect the installation from lightning and the build-up of static
electricity.
The ground terminal is located on the lightning protector that attached with
this unit. Connect one end of the grounding cable to the Ground terminal and
the other end to a good ground connection.
The package content contains a lightning arrestor, and should be installed
and grounded at the point where the cable enters the antenna.
3. Connect the Antenna and Lightning Protector
The bridge connects to a Lightning Protector directly and the Lightning
Protector connects to the outdoor antenna with a standard N(Mu)-N(Mu) type
low-loss cable. A longer cable may decrease the distance achievable between
antennas.
The picture of lightning protector is shown in Figure 2-7.
4. Antenna Mast Requirements
To accommodate the outdoor antennas, the antenna mast must satisfy the
following requirements:
Ÿ The construction of the mast must be of a sturdy, weatherproof and no
corrosive material like for example galvanized or stainless steel construction
pipe.
Ÿ Typical diameter of the mast should be between 35 mm (1.4 in.) and 41 mm
(1.625 in.). Subject to the type of antenna that you intend to install other
diameters may be possible as well.
Ÿ The height of the antenna mast must be sufficient to allow the antenna to be
installed at least 1.5 m (5 ft.) above the peak of roof. If the roof is metal,
then the height of the antenna should be a minimum of 3 m (10 ft) above the
roof.
Ÿ The mast or wall-bracket must be free from any substance that may prevent
a good electrical connection with the antenna; for example, paint.
5. Connecting the Ground Wire
Direct earth grounding of the antenna and the Lightning Protector is
necessary to protect the installation from lightning and the build-up of static
electricity.
The Ground terminal is located on the lightning protector that attached
with this unit as shown in Figure 2-7. Connect one end of the grounding cable
to the Ground terminal and the other end to a good ground connection.

Figure 2-7 Lightning Protector
6. Connect the Ethernet and Power Cable
Ÿ Connect the power code to the DC-IN port on the rear panel of the
DC-Injector.
Ÿ Connect an Ethernet cable to the RJ-45 port (To LAN) on the rear
panel of the DC-Injector. Use the straight cable to connect to the
HUB/SWITCHA or use the crossed cable to connect to the PC’s
Network Interface Card (NIC).
Ÿ Connect an Ethernet cable to the other RJ-45 port (To Bridge) on the
rear panel of the DC-Injector and connect the other end to the LAN1
(PoE) port on the side of DC-Converter.

9. Connect to the other Bridge
For some special reasons, you may need to install two bridges as a
wireless repeater to lengthen the coverage range. Connect two bridges using a
crossed cable and plug into the LAN2 port in the side panel of the
DC-Converter as shown in Figure 2-2. Refer to the Chapter 3.3 for creating
two of Bridges as a wireless repeater.
10. Antenna Alignment
In case Bridge A is connecting with network IP 192.168.123.100. Bridge
B is connecting with network IP 192.168.123.101.
1. Figure out the rough direction/ location for both of the communication
stations A and B by map finding or by experience in using GPS/
compass/ telescope first!!
2. Connect both station stations A and B, roughly fix the Antenna and
pointing to the station direction for each other.
3. In DOS Mode, Ping A computer to B computer. (command：ping
192.168.123.101 –t ).
4. Stay B ANT. in the same direction, Fine tune A Antenna only with small
angle (less than 5 degree) in up/down/right/left direction, please check
the result of IP being ping, make sure the system in linking condition as
well as the time out possibility and response time as low as possible, if
the system been tuned to this condition, it is time to fix the A Antenna.
5. If the A Antenna has been fixed, please tune and fix the B Antenna
according to procedure 4. (Command for B computer to Ping A
computer: ping 192.168.123.100 –t).
6. If the link quality and the signal strength not in reasonable performance,
please repeat step 4 and 5 until optimum condition.

Chapter 3 Create a Bridge Network Environment
3.1 Bridge Configuration
1. Login this device with the administrator’s password as “admin” (default).
2. Select Primary Setup.
3. In the Primary Setup page, make sure the Mode is Bridge.
4. Enter the address into IP Address field which is in the same subnet with your
network environment.
5. Set the “Channel” and “SSID” of this device and another one which you want
to connect in the same channel and SSID.
6. Save the settings above and then reboot this device.
Figure 3-1
3.2 Create a Bridge Network Environment
The bridge supports external gain antennas with omni-directional or directional
capabilities. Omni-directional antennas are suited for systems requiring a signal
distribution in more than one direction. High-gain directional antennas are best suited
for longer coverage range in a fixed direction.
Due to the differences in placement and physical environment, every network
application has their unique installation. Before installing multiple bridges, you
should implement a testing of each site to determine the optimum networking
components and to maximize coverage range and network performance.
Think about the operating and environmental conditions of following when
implement this testing:
18
1. Multipath propagation
Transmitted signals can combine with reflected ones to corrupt the signal
detected by the receiver. The PATH between two antennas is a straight line as
shown in Figure 3-2. Any obstacle in this PATH can redirect parts of the
transmitted signal as shown in Figure 3-3. The best propagation path is a clear
line of sight with good clearance between the PATH and any physical obstacle.
Figure 3-2
Figure 3-3
Clearance
19
2. Path loss
Path loss between the transmitter and receiver is a key consideration when
designing a wireless LAN solution. Expected levels of path loss, based on the
range between the transmitter and receiver, provide valuable information when
determining requirements for transmit power levels, receiver sensitivity and
signal-to-noise ratio. Actual path loss depends on the transmit frequency, and it
grows exponentially as the distance increases between the transmitter and receiver.
In addition, path loss is minimized when there exists a clear line of sight and is
lower when antennas are positioned higher. Refer to the potential obstacles to
Line of Sight as shown in Figure 3-4, Figure 3-5 and Figure 3-6.
Figure 3-4
Figure 3-5
Figure 3-6
20
3. Physical environment and Obstructions
Open areas provide better coverage range than closed areas. Also, the
obstructer such as steel buildings or trees can block or decrease communication
between bridges. To avoid this situation, the antennas should be located in where
is no or few obstruction between the sending and receiving antennas.
4. Rooftop Installation
Rooftop installations offer several advantages such as Fewer obstacles in
path, Increasing the range of antenna, reducing multipath problems and
Improving performance due to greater height. But please notice that Rooftop
Installations are extremely dangerous! Incorrect installation way may cause in
serious injury or death. Such installations should be performed by the professional
installer.
5. Throughput of Data
Coverage range is inversely proportional to data rates. The maximum radio
range is achieved at the lowest workable data throughput.
21
3.3 Connect Buildings by using Bridges
Wireless point-to-point networks use technologies very similar to wireless
LANs. A radio-based wireless point-to-point network as shown in Figure 3-7 and
Figure 3-8 is currently the most common method for providing connectivity
within a metropolitan area. All of these bridges have to use highly directional
antennas to focus the signal power in a narrow beam, in order to maximizing the
transmission distance. The actual transmission distance of a particular product,
depends on environment conditions and terrain. Rain, for example, causes
resistance to the propagation of radio signals, decreasing the effective range. A
mountainous area will also hamper the transmission range of the signals. Refer to
Chapter 3.2 for determining how to set up the wireless bridge environment.
3.3.1 Point to Point Configuration
In point-to-point configuration, a pair of bridges is set up to communicate only
with each other. In a typical point-to-point application, the bridge acts as a data
channel, providing a wireless link between sites separated by considerable
distances. Actual distance attained depends on the antennas used and their
installation. Both voice and data can be transmitted between sites.
Figure 3-7
22
Figure 3-8
23
3.3.2 Repeater Configuration
The repeater configuration extends maximum communication range beyond
the radio horizon. An additional pair of bridges is set up at an intermediate site,
one oriented towards each of the end points. Transmissions from one end point are
received by the intermediate bridge facing it, passed by wire to the other
intermediate bridge, and retransmitted to the other end point. This configuration
normally requires directional antennas for maximum range.
Figure 3-9
NOTE: To minimize the influence of obstacles, signal interference or reflections,
install the antennas at least 2 meters (6 feet) away from all other antennas. Use
the straight cable (RJ-45) to connect to the HUB/SWITCHA or use the crossed
cable to connect to the PC’s Network Interface Card (NIC).
