GE/AR80 Installation Manual  
2 Site Planning  
2.1 General  
Before the start of an installation a survey should be conducted of the proposed area of  
the deployment site(s). The survey personnel should be fully familiar with the details  
required to install the GE/AR80 radio system.  
2.2 Equipment Checklist  
We suggest the site survey team may need the following equipment:  
Binoculars (not always required)  
GPS location device  
Tape measure to determine distances for cable runs to ingress points  
Digital camera (not always required)  
Site survey report form to document and help assess site  
Signaling mirror (provided and not always required)  
70-90GHz Link Registration Datasheet. Contact BridgeWave Tech Support to  
learn where one can obtain the latest version of this form. You may E-mail  
support@bridgewave.com for this request.  
2.3 Line of Sight (LOS)  
The GE/AR80 Wireless Gigabit Ethernet link requires LOS for proper operation.  
Binoculars and spotting mirrors can be used to assist in confirming a LOS.  
Path planning should include an investigation into future building plans that could block  
the LOS path, and other long-term incremental obstructions such as tree growth.  
Intermittent obstructions such as aircraft at a nearby airport should also be considered.  
The following table details the minimum clearance needed from obstacles in order to  
ensure the radios will operate properly.

GE/AR80 Installation Manual  
2.4 Link Distance  
Measurement of the link distance is important in estimating the link availability and  
calculating expected Receive Signal Level (RSL). This measurement can be performed  
using the Latitude and Longitude coordinate readings from a Global Positioning System  
(GPS) device, which is placed near the proposed locations of the antennas. Additionally  
GPS reading will be required in order to comply with the FCC registration process.  
To quickly obtain estimated distances and availabilities for a given product and region,  
use BridgeWave’s path calculator. To obtain the latest version of BridgeWave’s Path  
calculator, contact BridgeWave’s Customer Service.  
2.5 Antenna Location  
The optimum location for the antennas must be determined. The ideal location should  
provide for ease of erecting and mounting the antenna, as well as providing unimpeded  
LOS to the remote location. The following factors should be taken into account:  
Type of mounting—fixed or roof-safe pole mounting  
Location where the fiber and DC power wiring will enter/exit the building  
Length of cable runs  
Grounding connection points  
Obstructions, including allowances for tree growth  
Accessibility of mounting location  
Access to building after regular working hours  
2.6 Cabling  
The installation site should be inspected to determine the run paths for the fiber cable and  
power cable from the radio equipment to the termination point. Locations for roof  
penetration should be identified. The routing and securing of all cables should conform to  
all applicable codes and requirements. Depending on the likelihood of damage due to foot  
traffic or equipment movement, cabling conduit may be required. The maximum cable  
run length as specified for the equipment being installed must not be exceeded.

GE/AR80 Installation Manual  
The radio requires LC type connectors on a pair of simplex multi-mode fibers to properly  
connect between the radio and the users network equipment. Single-mode fiber  
connections are not supported for use with the standard product. The network equipment  
end of the fibers should be terminated with connectors that match the user’s network  
equipment fiber interface.

The GE/AR80 radio includes a 100-240 VAC power adaptor suitable for indoor operation  
only that converts the AC voltage from a standard electrical outlet in the wall to DC  
voltage. The radio requires a minimum of 15.0 VDC at the connector on the radio unit  
(24.0 VDC maximum) to function properly. When planning the cable run from the indoor  
AC power adaptor to the radio unit, it is required to use the cable gauge (AWG) indicated  
below to ensure adequate voltage at the radio. The indoor and outdoor portions of the  
DC power cabling must conform to all respective indoor and outdoor national and local  
electrical and building codes; note that requirements may differ for the indoor and  
outdoor portions of the cabling and that a grounded surge protector is normally required  
at the point where the cable enters the building. The DC power cabling must consist of  
two 12 or 14 gauge conductors based on the required cable run length.

2.7 Grounding & Lightning Protection  
WARNING!  
Proper grounding of the outdoor equipment reduces electromagnetic interference,  
provides surge protection, and protects against electrical discharge. The source and  
connection points for the building-to-earth ground in the vicinity of the antenna location  
should be determined.  
It is recommended to connect the radio to the building ground by connecting the building  
ground to the conductive pole mount hardware structure. For wall or ungrounded pole  
mounts, connect a grounding wire to the grounding point on the radio. Select the size of  
the ground wire based on the National Electrical Code.  
In addition to grounding the equipment, BridgeWave strongly recommends, and local  
building codes may require, the DC electrical cable to be protected from electrical surges.  
You should use a Polyphaser surge suppressor, model # IS-PSP-24 or equivalent (not  
provided). The surge suppressor must be installed at the point where the DC electrical  
cables exit/enter the building.  
The Polyphaser device is available from the following companies:  
Hutton Communications  
TESSCO Technologies  
Winncom Technologies Corp.

3.6 Antenna and Radio Installation  
1.  
Install – Antenna and Radio  
Captive bolts  
Figures 3-7 and 3-8: The first letter of the designated Polarization is stamped onto each unit to  
identify orientations when the polarity mark is positioned on top: illustrations above are for  
Horizontal (left) and Vertical polarity right).  
CAUTION!  
It is critically important during installation to ensure the radios on each side of the  
link are in the same polarization (horizontal-horizontal or vertical-vertical). A link  
that has a radio on one side of the link set in the horizontal polarization and the  
other side of the link set in the vertical polarization will not operate properly.  
Further, it is also critically important that a high-band radio is paired with a low-  
band radio to ensure the system will operate properly. Prior to installation check  
each radio to verify one is a high-band and the other is a low-band version. The  
label on the radio will indicate the band (blue for high or red for low).  
2. Verify that the four (4) captive 3/8-16 bolts with lock and flat washer are in place.  
A 9/16-inch open-end wrench is required to tighten them. It is important that all  
four screws are tightened evenly (hand tight, 1 to 2 turns each until the lock  
washer is flattened)  
3. Adjust azimuth illustration (Side to Side)

3.7 Cable Installation  
Fiber Cabling  
1.  
Install a duplex multi-mode fiber from the radio to the network termination  
equipment (switch or router with 1000Base-SX port). The cable should be looped  
around the inside of the enclosure to provide strain-relief. Do not connect the fibers  
to the radio’s fiber ports at this time.  
The connectors on the radio end of the fiber require simplex LC connectors; the  
connectors on the switch/router end should mate to the network equipment.  
Note: The simplex LC connectors for the radio need to be inserted individually  
through the 3/4” conduit water tight connector fitting on the radio, as there is not  
sufficient room for both to fit through at the same time if connected with a duplex  
clip. If a duplex clip is used, it can normally be temporarily removed to complete  
the installation.  
2.  
Connect fibers at the network equipment. It is important not to connect the fibers  
to the radio until after aligning the radio as the radio performs an automatic  
calibration once the fiber is inserted into the radio and this calibration will not  
operate properly if the radio is not properly aligned.  
Power Cabling  
1.  
Select indoor location, with easy cable routing to the radio, for the AC power  
adaptor. Normally it is convenient, but not required, to place the adaptor near the  
network termination equipment.  
2.  
3.  
Ensure the DC wire used is 14-gauge type and no longer than 125 meters; or 12-  
gauge and no longer then 200 meters.  
Connect the provided DC Connectors onto the 14-guage wire using a  
splicing/crimping tool. For the use of 12-gauge wire it may be necessary to trim a  
few strands from the ends of thicker stranded cables to more easily fit the crimp  
connectors.  
4.  
5.  
Install the DC power cable and attach to the AC adaptor using the supplied crimp  
connectors. Do not connect the power jack to the radio at this time.  
IMPORTANT: Be sure to first connect the DC power crimp connectors before  
inserting the power plug into the power jack in the radio. No sparks should be  
expected with the new two conductor (green) power connector.

Note: The fiber and power cables are inserted through the straight through fitting, before the  
conduit is connected to the fitting. Ensure that the cables do not get pinched when the conduit is  
pushed onto the fitting. Both cables have been looped around the inside of the enclosure to  
minimize tension on the cables when connected to the radio and to maintain proper bend-radius  
of the fiber cable.  
Ground Cabling  
The preferred method for grounding the radio unit is to ground the mast to a ground  
source, since this provides the largest grounding surface contact possible. If this is not  
possible, then use the following procedure:  
1.  
Attach the lug of the ground cable (not provided) with the radio to one of the two #8  
holes at the bottom of the radio using a #8-32 x ½” long bolt, #8 lock washer and #8  
flat washers (not provided). Yes  
2.  
Connect other end of the ground cable to a nearby ground location.  
10/100BaseT Surge Suppressor  
If the 10/100BaseT port is permanently connected to other network equipment  
(not normally required), it should be connected using Cat5e cables rated for the  
outdoor and/or indoor environments where the cables will be run. It is essential  
that the cabling be connected to the radio unit through an Ethernet-rated surge  
suppressor inside of the plastic back cover of the unit, and a surge suppressor  
should also be used at the point where the cable enters a building or is connected  
to other outdoor equipment that does not already contain surge suppression  
hardware. BridgeWave recommends the Dehn model DPA-M-CAT6- RJ45S-48  
surge suppressor be used. See figure 3-15 below.

3.8 Turning the System On and Alignment  
1) Before Turning On the System  
a) Finish the installation as described in Chapter 3.6 and 3.7  
b) Ensure fiber cables are still disconnected!  
c) Connect DC power to the radio.  
d) Verify that the Power LED is lit. If the Power LED is not lit, use voltmeter to  
verify correct voltage and polarity at radio. To reverse the power polarity, unplug  
the power jack and swap the crimp connectors for the two conductors.  
e) Repeat steps 1 through 4 on the far-end of the link.  
2) Prepare to Rough Align the Radio  
a) Connect RSL test lead cable to radio and place voltmeter with readings in view  
b) Loosen the pole mount brackets enough to allow you to swing the unit  
horizontally.  
c) Reference Chapter 3.6 for illustration of antenna mount bolts and their purpose.  
3) Rough Align the Radio Antennas  
a) Set the radio terminal to the pre-defined azimuth if available. If not, you may  
utilize binoculars or mirror to locate the far end radio location.  
b) If you can see the far-end radio terminal estimate the alignment visually and  
tighten the pole mount brackets with fine adjustment bolt set to the middle of  
adjustment range.  
c) Ensure the horizontal adjustment bolts are snug; only tighten bolts one quarter of  
a turn.  
d) Slightly rotate each antenna up/down for best vertical alignment and left/right for  
best horizontal alignment by finding the maximum RSL voltage reading.  
e) To ensure that the antennas are not aligned on a side-lobe, they must be rotated at  
least ten degrees on each side of the visually-perceived alignment center to ensure  
that the true maximum RSL voltage is found; note that the width of the center  
beam is only 0.9 degrees and the first side-lobe beam is only 1 degree off from  
center.  
f) Set the antenna in the position that results in the highest RSL voltage reading.  
g) Repeat these steps on far end radio.  
4) Fine Adjustment  
a) Ensure to loosen the “fine adjustment” bolt (the small eye bolt)  
b) Pan antenna slowly from left to right and capture the highest RSL voltage peak  
i) See Figure 3-15 below to help guide you in obtaining the highest RSL voltage  
reading.  
c) Tighten down the Horizontal control bolts.

d) Loosen the two vertical control bolts holding the antenna to the antenna mount  
e) The Vertical Fine adjustment is not designed to be tightened; use the “hex nut” to  
fine (and rough) adjust the elevation (vertical position) to highest RSL value.  
f) While monitoring the Voltmeter, begin to align the Vertical position of the  
antenna to obtain the highest RSL voltage level.  
g) Once completed, this fine adjustment must be repeated at the remote end of the  
system, if you have not obtained the “target” RSL voltage for the given path  
distance (see RSL Vs. distance chart on Chapter 6).  
h) If you are have not obtained the “target” RSL voltage for the given path distance  
(or you want to further improve it), you will need to re-align the antenna, go back  
to the original site you started with and restart steps (a-f) and re-align again. See  
Figure 3-15 below of a conceptual illustration of and antenna beam to keep in  
mind while you perform a re-alignment.  
i) Once again, the very narrow beamwidth of this antenna (0.9º) makes it necessary  
to completely tighten the bolts of the azimuth adjustment while adjusting the  
elevation and vice versa.  
Note: Verify that the RSL voltage falls within the expected range based on the graph in  
Appendix A.

c) Always evenly tighten bolts in small fractions at a time to ensure minimum  
change to your completed alignment.  
6) Connecting the Fiber  
a) Connect the fiber cable to one of the radios at a time. The fibers should already be  
connected to active network equipment.  
b) Verify the fiber LED’s on each of the radios are illuminated solid  
Note: The fiber integrity indication on the network equipment could show up or  
down independent of the link status.  
7) Auto Calibration  
a) Once the fiber is connected to the radio, the radio will begin an internal link  
calibration.  
b) During this time the Link Up LED will blink for approximately 120 seconds.  
c) Wait until the Link Up LED is lit solid  
d) Verify the Link Quality voltage is 3.0-3.3V (i.e., error free). Repeat steps (a-c) for  
the far-end radio. For more details on Auto Calibration see section 3-9 below  
8) Removing the Test Cable  
Removing the test cable from the radio, replace the rear plastic cover and hand  
tighten the back cover nut to the point where the back cover stops (i.e., when it  
hits the metal ring on the back metal plate). The installation is now complete.  
The most important alignment "tools" for these models are care and patience! It is  
recommended that these models be aligned with personnel present at both ends of the  
link, and the installers should allow up to 90 minutes to optimally align these units.  
The GE/AR80 links have a narrower beamwidth (0.9 degrees) than the GE/AR60 radio  
beamwidth (1.4 degrees) and operate at much farther distances.  
3.9 Auto Calibration  
The Auto Calibration feature scans the RSL level of the system (after the system is  
aligned) on each radio terminal where the level is calibrated against an internal  
calibration table that corresponds to an expected receive power level. The radio system is  
said to be in Alignment Mode when it is first powered up and no fiber is connected. Once  
the alignment is completed; the Auto Calibration mode is triggered ON as soon as the  
fiber cable is connected. You will know the radio terminal has initialized the Auto  
Calibration when the Link LED is flashing on/off - this lasts for up to 120 seconds. The  
radio terminal needs to detect an optical signal of the appropriate Wavelength. For this,  
one would require having the fiber optic cables terminated to a fiber port on a switch or  
this can be accomplished with a fiber optic jumper cable by connecting the fiber output of  
the radio into the fiber input of the radio. Loopback should only be connected long  
enough for auto-calibration to start and should be removed immediately.

Losing RF connectivity  
When a system loses the RF connection for more than 5 minutes it will trigger the system  
to enter an Auto Calibration mode. You can disable this function on the AR80 units via  
the NMS. Please review the NMS Manual for further details on disabling this function.  
Force Calibration  
You can induce a force calibration at anytime by disconnecting DC power and fiber optic  
cables from the radio. Powering up the radio terminal while the fiber connectors are  
disconnected will induce a Force Calibration, as soon as the fiber optic cables are  
reconnected to the radio terminal will.  
Also, if using a loop back fiber connector at one end of the link for test purposes, note  
that the radio connected to actual network equipment must complete auto calibration  
prior to connecting the loop back cable at the other end.  
Power Cycling a Radio  
When a radio is power cycled and it’s fiber cable is disconnected, it will re-execute the  
calibration process. After this, the link will be functioning.

3.10 Test Cable  
The alignment procedure is optimized through the use of the provided test cable. This  
test cable is designed for use with a digital voltmeter (not provided) to read the Link  
Quality and Receive Signal Level (RSL) voltage generated by the radio’s receiver.  
1.  
To read the RSL value of the radio, insert GND (ground) and RSL banana plugs  
into the voltmeter. Note the RSL voltage. The voltage may be fluctuating; in this  
case, note the maximum value seen.  
Figure 3-15: Top view of test cable provided to check Link Quality & Receive Signal level  
2.  
To read the Link Quality value of the radio, insert GND (ground) and QUAL  
banana plugs into the voltmeter. Note the Link Quality voltage. After the radios  
have performed an auto calibration the quality voltage should read 3.0-3.3v if the  
link is aligned on the main antenna beam and there are no obstructions (i.e., trees,  
buildings, etc…) in the path, the link distance is within the operating parameters of  
the radio (see Section 2.4 above), and it is not raining heavily.

4.1 Configuring Network Equipment  
The networking equipment that is connected to the GE/AR80 should be checked to  
ensure it operates properly over a wired connection. Once this has been confirmed it will  
save troubleshooting steps after the radio is installed and connected to the network  
equipment.  
We strongly recommend the network equipment on both sides of the link be configured  
as follows:  
1000Mbps full-duplex  
Port configured not to enter error-disable state due to link up/down transitions  
(since these may occur during periods of very heavy rain)  
For AR model only, ensure to disable the, Installation Auto-Calibration selection  
via Set Up GUI section, post installation.  
4.2 Check Port Statistics on the Network Equipment  
In the event the network equipment connected to the GE/AR80 offers the capability  
below, we recommend you verify the following on the network equipment:  
Link integrity  
There are no receive errors on the link  
Network traffic is flowing in both directions
