wireless building-to-building
bridge solution, BR5811 provide
the data rate up to 108 Mbps that
is best suited for enterprises,
campus or off-site locations that
require LAN or Internet access
without the availability of wired
networks to extend the network
coverage. BR5811 provides the
point to point and point to
multi-point connection.
The wireless building-to-building
bridging solution contains a state
of the art wireless Bridge, high
gain performance 17dBi flat panel
antenna and Power over Ethernet.
For further protection, the bridge
and Power over Ethernet adapter
have build in lightning protector.
Supporting up to 16 station
associations including the Bridge itself. Rates of 6 to 54 Mbps are supported in standard
IEEE 802.11a modes, and up to 108 Mbps in Atheros Turbo Mode. All 802.11a transmission
rates are supported across the 5.15 to 5.85 GHz spectrum.
1-1 System Requirements
The Bridge contains a small boot executive that allows the main operating system software to
be downloaded using the Ethernet port over an FTP connection. The Operating system
software can also reside in the Flash memory of the Bridge, which allows booting without the
need to download the operating system from the host PC over an FTP connection. A
configuration file is created in Flash memory to store user-configurable parameters such as
WEP keys. A terminal or PC with an Ethernet connection is required to perform the initial
Bridge configuration. An FTP server is required for firmware update to the Bridge.

1-4 Hardware Architecture
WARNING: If end users are allowed to upgrade firmware through the FTP server, confirm that the End
User License Agreement (EULA) covers upgrades to the firmware. The Reference Design upgrade code
permits direct upgrades of the Bridge from the configuration screen if a web browser is used. As a
precaution, also use the EULA as the FTP startup text in the event some end users log in to the FTP
server manually.
Use the Bridge Web Server for firmware updates. Refer to “Firmware Update Configuration
Window”for information on the web server.

Chapter 2 Hardware Installation
This chapter provides installation procedures are generally outlined as follows:
 Verify system configuration
 Installing the ODU
 Installing the POE
 Mounting and alignment the antenna
 Connecting external equipment
You may need to use Web Browser to
change or set the MTI BR5811 system’s
operating parameters. Refer to chapter 3,
Bridging network attachment and configuration, for more information.
2-1 Unpacking the Equipment
The tools required for unpacking the system equipment are:
 Utility knife
 Clean, flat working surface
Open the shipping containers, carefully remove the equipment and place it on a clean, flat
working surface. Save the shipping and packing material in case the equipment has to be
returned.
Check the equipment and installation kits against the packing list to ensure that the equipment
part numbers, parts, and ancillary equipment included in the shipment match what is specified
on the packing list. Shipments consist of an ODU and an installation kit in one container. Verify
the configuration as described in verifying the System Configuration. If there are discrepancies
between the packing list and the equipment received, contact your sales representative.
Inspect the equipment for any type of shipping damage. If any part of the shipment is damaged,
contact your sales representative for repair or replacement instructions.
2-2 Verifying the System Configuration
The MTI BR5811 system consists of an Outdoor Unit (ODU), POE and an installation kit.

802.11a Bridge BR5811 MTI Proprietary Page 15
2-3 Installation Kit
Most of the materials needed for installation are supplied with the system. Some tools and
equipment must be supplied by the user. Table lists materials in a typical installation kit. Refer
to the packing list for a description of the exact contents.
Table Installation Kits (for 2” Steel or Stainless Steel Tube)
Item Description Quantity
1 M-TYPE PLATE 1EA
2 L-TYPE PLATE 1EA
3 U-TYPE PLATE 1EA
4 NUT FLANGE M8-1.25 SS (PLATE ASM) 3EA
5 NUT FLANGE M8-1.25 SS (HOUSING ASM) 4EA
2-4 Grounding
Proper grounding of equipment and structures is essential to prevent electrical damage to the
MTI BR5811 system.
Grounding of all equipment at a radio site is required. Without proper grounding, voltage
potentials between components of the system can cause electrical damage when
interconnecting cables are installed.
It is recommended that the ODU be installed with lightning rod protection. Also, to avoid surge
current caused by lightning circulating to the equipment earth system, connect the equipment
earth system (true ground) to the lightning rod ground.
Please connect the ground node to the existing ground.
Note: Ground wires and hardware are not provided in the installation kit.
2-5 ESD Protection
ESD (electrostatic discharge) can damage electronic components. Even if components remain
functional, ESD can cause latent damage that results in premature failure. Personnel and
equipment must be properly grounded. Always wear proper ESD grounding straps during
equipment installation, maintenance and repairs. Connect your ESD grounding strap to the
ESD connector.

ODU Configuration
You can refer the photo here for installation.

802.11a Bridge BR5811 MTI Proprietary Page 18
2-8 Connecting the cable
An Ethernet cable connects the ODU to the POE output port. The cable connects power to the ODU
and allows Ethernet data to flow between Stations with Bridge system. Another Ethernet cable
connects the station to POE input port. AC power is applied to the bridge system by connect it to POE
AC adapter.
2-9 Align the Antenna (TBD)
Notices
The RSSI BNC connector is still not function well now. Please use the RSSI
reading from the statistics window in WEB -base browser.
Antenna alignment is performed with both the near-end and the far-end terminals operating.
The antenna position is adjusted while monitoring the RSSI for antenna alignment voltage. The
higher the RSSI voltage reading is, the stronger the signal. The range of the RSSI voltage
reading is from 0 to 3.28VDC, and the resolution is 256 divisions.
Caution: To ensure optimum system performance, the main lobe of the antenna must be aligned with the center
of the far end antenna. Rotate the antenna through the range of radiated power so the main lobe can be positively
identified. Each side lobe is approximately 20 dB lower than the preceding lobe as you move away from the main
lobe.
This antenna alignment procedure is applicable to both protected and non-protected system
configurations. Align the antenna as follows:
Note: Repeat this procedure if the initial alignment does not produce the correct RSSI reading.
1. Consult your path calculation and adjust the radio’s attenuation level, so do not exceed
the maximum receiving signal level.
2. Verify that the Bridge at the far end is operational.
3. At the near-end Bridge, remove the protective cap from the RSSI BNC connector.
4. Connect a voltmeter to the RSSI connector and set the voltmeter to measure VDC.
5. Pivot the antenna slowly in the azimuth direction. Monitor the voltmeter and locate the
position where the voltage is minimum (null) and record the reading.
6. Monitor the voltmeter and pivot the antenna in the elevation direction. Pivot the antenna
to the position where the voltage is minimum on the voltmeter and record the reading.
7. Repeat these steps as necessary to get an accurate reading.
8. Tighten all fasteners and check that the null has not changed. If the null has changed,
repeat the procedure until the null is maintained after tightening the fasteners.
9. Disconnect the voltmeter and replace the RSSI protective cap.
Note: The signal level over the link is not optimal until both antennas are correctly aligned.
