1.3 Safety The following general safety precautions must be observed during all phases of operation and service of the products covered in this manual. Failure to comply with these precautions or with specific warnings elsewhere in this manual can void the user’s authority to operate the equipment.
Do not stand directly in front of an energized antenna. Do not install or operate the equipment in the presence of or close to flammable fumes or gases. E-Band radios meet all applicable FCC safety requirements for general population exposure to radio frequency emissions; however, it is best to avoid prolonged, unnecessary exposure to the front of the radio while it is operating Please refer to Articles 810 and 830 of the National Electrical Code, ANSI/NFPA No. 70, for installations in the U.S.A for information regarding proper grounding and applicable lightning protection for DC cables. Outdoor equipment must be properly grounded to provide some protection against voltage surges and built-up static charges. In the event of a short circuit, grounding reduces the risk of electrical shock. Changes or modifications not expressly approved by E-Band can void the user’s authority to operate the equipment. For installations in all other countries, implement protection in accordance with the safety standards and regulatory requirements of the country where the equipment is to be installed.
1.3.1 Protection from Lightning Article 810 of the US National Electric Department of Energy Handbook 1996 specifies that radio and television lead-in cables must have adequate surge protection at or near the point of entry to the building. The code specifies that any shielded cable from an external antenna must have the shield directly connected to a 10 AWG wire that connects to the building ground electrode.

1.3.2 Protection from RF Emissions It is hazardous to look into or stand in front of an active antenna aperture. Do not stand in front of or look into an antenna without first ensuring the associated transmitter or transmitters are switched off. Do not look into the waveguide port of an ODU (if applicable) when the radio is active. 1.3.3 LASER SAFETY NOTICE This product complies with CFR 1040.10, 1040.11 and EN (IEC) 608251 regulations and safety standards. The product may include a Class 1 laser utilized as a fiber optic driver. Class 1 lasers do not emit radiation at known hazardous levels. However, it is recommended that maintenance or service personnel should never look at an open fiber end or connector that is carrying a live signal. During use, this optical fiber communications system is completely enclosed except if an accidental break occurs in the system cable, or if the patch cable becomes accidentally disconnected from the demarcation box. There are no controls or adjustments other than power ON/OFF that may be accessed by the user.
Risk of Personal Injury from Fiber Optics DANGER: Invisible laser radiation. Avoid direct eye exposure to the end of a fiber, fiber cord, or fiber pigtail. The infrared light used in fiber optics systems is invisible, but can cause serious injury to the eye. WARNING: Never touch exposed fiber with any part of your body. Fiber fragments can enter the skin and are difficult to detect and remove.
CAUTION: Use of controls or adjustments or performance of procedure other than those specified in this Manual may result in hazardous radiation exposure. 1.3.4 CONSTRUCTION SAFETY NOTICE Note that locality has its own codes of safety and construction. Equipment installations like this must comply with these codes. It is the installer/user’s responsibility to understand what codes apply and to ensure that the installation conforms to these codes.

4 Product Overview E- Link millimeter wave transmission systems provide a cost effective solutions for ultra-high capacity point-to-point wireless network connections. E-Link operates in the 71-76 and 81-86 GHz millimeterwave bands supporting a tributary data rate of 1,250 Mbps (i.e. line data rate of GigE) in full duplex mode. Like most high frequency radio transmission systems, millimeter wave systems require line-of-sight. In the United States and other countries the operational frequency band covers two band segments from 71-76 and 81-86 GHz. In order to operate in this band requires a license to operate from the Federal Communications Commission (FCC) or local regulatory body. Please consult the regulator in your area for operating requirements.

5 Site Planning Before the start of an installation a site survey should be conducted of the proposed area of the deployment of the link. The survey personnel should be fully familiar with the details required to install the E-Link radio system. Section 9 and Section 10 contain site survey process and check list to aid in determining the applicability of E-Link for your site. E-Band can also help you with the feasibility and calculate the link availability in your area. Please contact your E-Band representative for link feasibility and availability support.
5.1 Line-of-Sight (LOS) The E-Link Wireless Gigabit Ethernet link requires line-of-sight (LOS) for proper operation. Binoculars and signaling mirrors or strobe lights can be used to assist in confirming LOS condition exists. Path planning should include research into future building plans that could block the LOS path, and other long-term incremental obstructions such as tree growth, and intermittent obstructions such as aircraft possibly flying through the path should be considered. Additionally, no obstacles should be situated in the vicinity of the signal propagation line (inside the first Fresnel region). Because the link distances are usually within 6 miles (10 km), obstructions in the path can easily be identified using binoculars. The characteristics of a radio signal cause it to occupy a broad crosssection of space, called the Fresnel Zone, between the antennas. Figure 3 shows the area occupied by the strongest radio signal, called the First Fresnel Zone, which surrounds the direct line between the antennas. Because of the shape of the First Fresnel Zone, what appears to be a clear line-of-sight path may not be line-of-sight. As long as 60 percent of the First Fresnel Zone is clear of obstructions, the link behaves essentially the same as a clear free-space path. The first Fresnel zone radius is the greatest at mid-path (r).

5.2 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. The GPS readings are required to comply with the FCC registration process. The maximum usable link distance is controlled by the rain rate where the link will be located. Rain attenuation of millimeter wave signals has been the subject of numerous studies which has resulted in several mathematical models being developed to predict link availability. These models take into the account the attenuation and scattering of the millimeterwave signal during a rain event. The intensity of the rain event determines the maximum link distance based on specific link availability. The International Telecommunications Union has published charts dividing the world into various rain regions (see Figure 4, Figure 5, and Figure 6 for the charts of the world). These charts can be used as an aid in predicting availability performance of millimeterwave transmission systems. These regions are labeled by using an alpha notation with region A having the least and region P having the highest rain rate. Based on the rain region charts it is possible to calculate the link availability for an E-Link system in a specific rain region. The following chart estimates the link availability for given link availability and rain region within the United States.

5.3 Site Survey The following equipment may be useful in conducting the survey:
Binoculars WAAS-capable GPS location device determine latitude and longitude of each site Tape measure to determine distances for cable run lengths to ingress points Digital camera take pictures of the installation sites to reduce the need for return visits Site survey report for or sketch pad to document and help assess site Signaling mirror or battery powered strobe light for determining line-of-sight where it is difficult to determine each end of the link.
When performing the site survey that are a few important steps to follow ensuring a successful installation of the E-Link system. 1. Measure the point-to-point distance using GPS coordinates. 2. Determine the rain region the equipment will be located. 3. Ensure the antenna has sufficient path clearance. Table 1 shows the minimum path clearance required for operation of an E-Link radio. 4. Swaying vegetation or obstacles in the line-of-sight which can momentary interruptions. 5. Work activities or people passing in front of the antennas that could cause interference with the line-of-sight.
typically the radio terminal should be mounted near a roof edge mounting near roof edge reduces the chance of people interfering with the path and reduce the chance for RF exposure safe for damage by vandals
6. Verify mounting location for the antenna is stable and vibration free. 7. Evaluate the foundation at the mounting location is not susceptible to change due to humidity or temperature variations. 8. Adequate earth ground for the equipment is available for safety and lightning protection. Refer to local and national electrical codes for proper equipment grounding. 9. Determine the location that provides safe access to the radio and a stable standing platform.

6.3 Fiber Signal interface: A duplex Amphenol female PT/LC terminated fiber optic connection is the standard interface for the E-Link radio. For applications using the Gigabit Ethernet standard, it is recommended most customers should use Single Mode 1310nm interface although a Multimode 850n fiber connection is available. Figure 11 illustrates the required LC fiber plug to be used with the fiber outlet shown in Figure 7: Optical and Electrical Connections located on the ring of the radio enclosure. E-Band provides a preassembled weather resistant cable in the Installation Accessory Kit (ISK) with the required PT/LC connector on one end with a standard LC male on the other end. Using this pre-terminated cable will ensure a weatherproof connection.

6.4 Copper Signal interfaces: An RJ45 is the standard interface for the Copper E-Link radio tributary and the management port on all E-Link radios. The radio comes with a Amphenol boot (located in the ISK) for weatherproofing the RJ-45 interfaces. 25 of 60
6.5 Craft Interface Connection: When the hardware installation is complete, the units are ready to be configured using either a workstation or laptop running an HTML web browser. Initial setup of the radio terminal is through the use of the Craft RJ-45 port located on the ring of the radio closure. When connecting directly from a workstation or laptop an Ethernet crossover cable may be required. If connecting to a switch or hub prior to connecting to the radio a straight through cable is needed. E-BAND has verified User Interface operation with Microsoft® Internet Explorer 7 and Mozilla Firefox™ 2 Windows OS only supported. The easy-to-use browser based user interface UI allows configuration of the physical interface, display link status, set passwords, obtain statistics, and perform maintenance operations. At a minimum, the user should ensure that passwords and other security parameters are appropriately set. After logging on, the Operational Status screen will be displayed. The navigation bar across the left side of the screen provides links to the various management functions: The Operational Status page shows basic unit information including model and serial numbers, as well as the current state of the unit and its physical interfaces. Green, yellow and red status indicators Stop Light motif provides a quick visual summary of the terminal’s operating condition. Under normal operating conditions, the indicator should be green. Red indicator signifies a unit failure, unconnected network interfaces, or abnormal operating conditions. Yellow indicator signifies marginal operating conditions, which may impact unit operation. The displayed information is updated with every refresh of the Status page. Refresh of the page is automatic or a manual update can be requested by clicking on the browser’s refresh button.
6.6 Interfacing to the RSSI Port The RSSI Received Signal Strength Indicator voltage is a measure of received signal strength which is used in addressing link alignment. To measure the RSSI voltage, remove the weather cap for the BNC connector labeled RSSI, refer to Figure 7. Connect a Fluke DM Series 77 or similar to the BNC connector and note the RSSI voltage reading provides the correlation between volts and receiver signal level in dBm. The UI displays RSSI in Volts for E-Link 1000 prior to software revision 1.32. The E-Link 1000EXR with software revision 2.0 or higher reads directly in dBm.
26 of 60
Note: On the E-Link 1000 and E-Link 1000EXR the RSSI port will read a higher value if the internal BERT feature is enabled. The E-Link 1000 terminals are provided with curve which maps RSSI volts to dB when equipped with software revision 1.10p1 or lower. E-Link 1000EXR terminals provide RSSI voltage at the BNC test point and display RSL in dB through the UI.

7.4 How to adjust Azimuth left and right.
1. Slightly loosen the 4 Azimuth lock bolts
3. Secure the 4 Azimuth lock bolts (tighten until lock washers are flattened).
1. Adjust eyebolt length using a 9/16” open-end wrench to required position. Figure 23: Antenna Azimuth Adjustments
7.5 How to adjust the Elevation up and down. CAUTION! It is very important that the azimuth bolts are tightened before any elevation adjustment is done. The very narrow beamwidth of these antennas makes it necessary to completely tighten the bolts of the azimuth adjustment while adjusting the elevation and vice versa.
35 of 60
1. Loosen (2) antenna mounting bolts slightly so antenna is able to move. Loosening bolts excessively will cause difficulty during the alignment
2. Rotate Elevation Adjust Hex nut as require to set the correct elevation. Adjustment is easier when adjusting beam upward. Drive antenna down past desired location and adjust while driving antenna up.
Figure 24: Antenna Elevation Adjustments
When the antenna orientation is satisfactory recheck all hardware and torque to 15 lb-ft 203.3 N-m.
7.6 Radio Enclosure Mounting The Antenna Mount Bracket and Antenna as shown in Figure 25 is mounted to the pole. Supplied with the antenna is a small tube of silicon lubricant. Apply a small amount to the rubber “O”-ring located on the antenna feed. By applying this grease will aid in sliding the RF unit to the antenna and help seal against moisture from entering the feed.

Note: Drape cables with drip loop to keep water from collecting around connectors.
CAUTION! It is critically important during installation to ensure the radios on each side of the link are in the same polarization verticalvertical or horizontal-horizontal. That is, a link has a radio on one end of the link set in the vertical polarization and the other side of the link set in the horizontal polarization will not operate properly. Furthermore, it is critically important that a high-band radio is paired with a low-band radio to ensure the system will operate properly. Prior to installation verify each radio is a highband and the other is a low-band version. Vertical is the default polarization. The label Figure 27: ODU Product Label Figure 27: on the radio indicates high or low band operation.
Figure 27: ODU Product Label
38 of 60
Note: It is recommended that personnel be present at both ends equipped with either two-way radios or cell phones for communication and the installers should allow at 1 hour to optimally aligning the link.
Note: Handle orientation determines polarity. Top is horizontal, left/right is vertical.

8 Turn on and Link Alignment 8.1 Visually align the radios. Visually align the radios to each other. Be as accurate as possible. The beamwidth of the signal is approximately 0.9 degrees for the 1 ft 0.3m and 0.4 degrees for the 2 ft 0.6m, which is approximately equivalent to an index finger width when the arm is fully extended. Align as closely to the center of the main lobe as possible. Loosen the pole mount bracket enough to allow the unit to be swung horizontally with only slight resistance to movement azimuth. Visually align one end of the point-to-point link. Repeat this procedure for the other end; an aid in aligning longer paths where it may be difficult to see the other end of the link use of a small mirror or strobe light to “flash” the location. This concludes the visual alignment steps.
Caution! Lightning protection is required by the E-Band Warranty Statement. Failure to provide proper lightning protection can result in the Product Warranty being void. Lightning protection regulations and standards for proper protection are covered under the national or regional electrical safety codes such as the National Electrical Code in the United States. Follow your national or regional electrical safety codes! The outdoor components are to be grounded, and lightning arrestors are to be connected in accordance with local, regional and national codes. All local building and electrical codes specified by local civil authorities must be followed. Standard safety procedures for installing and working with this type of equipment must also be followed.

8.2 Rough link alignment. 8.2.1
Do not connect tributary fiber cable until link is aligned.
8.2.2
Connect a DV to the RSSI BNC connector on the RF Unit at each end of the link. The RSSI will vary between 0 and 5V with increasing RSSI resulting in an increasing voltage.
8.2.3
Verify -48 VDC power is connected to each radio and the radio is powered.
8.2.4
Using the User Interface UI set transmit power output to the value determined by the Link Calculation tool or from the UI ATPC Setup webpage. Refer to User Interface manual for additional information on this function. If aligning an E-Link 1000EXR radio navigate to the ATPC setup page and select “Disable” for the combo box and “Submit”.
8.2.5
Loosen the pole mount brackets enough to allow you to swing the unit horizontally azimuth.
8.2.6
Reference Figure 23 and Figure 22 for illustration of antenna mount bolts and their purpose.
8.2.7
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.
8.2.8
Ensure the horizontal adjustment bolts are snug; only tighten bolts one quarter of a turn.
8.2.9
Slightly rotate each antenna up/down for best vertical alignment and left/right for best horizontal alignment by finding the maximum RSSI voltage reading.
8.2.10
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 RSSI voltage is found.

8.2.11
Set the antenna in the position that result in the highest RSSI voltage.
8.2.12
Repeat alignment steps on the far end radio.
8.3 Fine link alignment. 8.3.1
Loosen the 4 each Azimuth Lock bolts so the mounting plate can move. Failure to loosen the bolts before adjusting will result in damage to the mount.
8.3.2
Adjust mounting plate using eyebolt and nuts to drive antenna to the peak RSSI indicated on the voltmeter. Swing antenna through the main lobe and out through the 1st right and left side lobe. Return to the main lobe as indicated by the RSSI value.
Note: It may be necessary to reduce the transmit power level during link alignment in each radio. This will keep the RSL at the distant radio fro saturating the Receiver which causes the RSSI to be near its maximum value on short links reducing the accuracy of aligning to the main lobe of the antenna. In addition, by monitoring the bit error rate of the link using internal BERT will significantly reduce the possibility of aligning the antennas to a side lobe.
42 of 60
8.3.3
Tighten down the azimuth adjustment bolts.
8.3.4
Loosen the two elevation bolts slightly holding the antenna to the antenna mount. Excessively loosening these bolts will cause difficultly during alignment. Caution failure to loosen these two bolts before adjustment will cause damage to the mount.
8.3.5
While monitoring the RSSI voltmeter and built-in BER indicator available from the UI. Begin Elevation adjustment by rotating the Elevation Adjustment Nut. Alignment is obtained by monitoring for peak RSSI and minimum BER. Again, swing the antenna through the main lobe and proceed to 1st side lobe confirming the alignment is on the main lobe. Then lock down the 2 elevation bolts when the RSSI is peaked and minimum BER is achieved.
8.3.6
Repeat procedure at remote end.
8.3.7
It may be necessary to repeat the procedure at both ends of the link obtaining the optimum signal strength and minimum bit error rate.
8.3.8 Figure 28: Antenna Pattern with Side Lobes
8.3.9
When link alignment is complete, if required for link performance, enable ATPC on each radio terminal for the UI. Refer to User Interface manual for additional information on setting ATPC.

8.3.10
Tighten the bolts to lock the antenna in place.
8.3.11
Always evenly tighten the bolts in small increments at a time ensuring minimum change to the completed alignment.
Note: While tightening the bolts continue monitoring the RSSI and BER values confirming the antenna s remain aligned. 8.3.12
Set link to normal operating mode: a. Remove fiber jumper from RF Unit b. Set radio to standard operating mode. This may be accomplished through the UI or briefly power cycling the radio terminal. c. Connect the optical cable for the network equipment. The link is now operational.
45 of 60
8.3.13
(E-Link 1000EXR Only) When complete, if required for link performance, enable ATPC on each radio terminal for the UI. Refer to E-Link 1000EXR User Interface manual for additional information.
8.4 Possible Issues encountered while aligning the link. The RSL level should be within 3 dB of predicted levels. Factors that contribute to low RSL levels are: 8.4.1
Incorrect antenna alignment - aligned to side lobe and not main lobe. While aligning the E-Band radios it is best to sweep the azimuth in a grid pattern. Make sure that all the side lobes are identified. Often times a side lobe will appear to be the main lobe. It is recommended that if you do not reach the target RSSI on what is believed to be the main lobe, try aligning to a side lobe.
Figure 32: Antenna Correctly Aligned
46 of 60
8.4.2
Improper polarization of antennas - Horizontal vs. Vertical.
Figure 33: Polarity Setting
8.4.3 Double check, make sure that both ends of the link have the correct polarization as indicated on link budget. Caution in shorter distances the link budget may recommend cross polarization. 8.4.4
Path issues.
Obstructions such as trees, hills, or buildings within the beamwidth
Figure 34: Path Obstructions
There can be many different obstructions that can block the path. Paths that are installed in the winter can be obstructed come spring when the 47 of 60
leaves grow back, cranes, ships, power lineman, window washers, hills, construction can all be potential obstructions to line of site 8.4.5 The mounting pole is not vertical.
Figure 35: Verify Mounting Pole is Plumb
It is very important to have the mast straight and plumb. If the mast is not plumb this can cause polarization decoupling which can cause additional signal loss up to 10 dB or more on a link.
48 of 60
8.4.6 Install mounting hardware evenly onto mast. If mounts are not evenly tighten this will cause the vertical plate to bind while panning the azimuth. This will also limit the adjustment range available.
Figure 36: Square Antenna Mount
8.4.7 Remove any foreign objects from the waveguide on the antenna. There is a small piece of tape which acts as a dust cover on every antenna. This dust cover must be removed before installation of the E-Link 1000 ODU.

9 Site Survey 9.1 Planning When installing an E-Link 1000EXR radio, proper link and site planning is required. E-Band can assist in feasibility and link availability analysis. Please contact your E-Band representative for support. The following items should be addressed during the planning process:
RF path engineering Site preparation, including power, tributary, and management connections Installation issues for E-Link Radio Unit Link licensing including frequency coordination FCC etc. Check local, regional, and national building and electrical codes Lightning and ground protection Surge protection Outdoor cabling requirement
9.2 Site Survey A site visit must be done prior to installation ensuring that proper lineof-sight path clearance exists and that the necessary facilities exist at the site as listed below. Line–of–Sight and Path Clearance: Determining the optimum location for the radio. The radio and antenna location are important to ensure optimum radio range:
Install the antenna as high as possible to maximize the range of a building-to-building connection Maintain a clear line–of–sight between E-Link antennas. Obstructions can impede performance and reduce signal strength. Maintain maximum path clearance at both ends of the link. When determining maximum path clearance, be aware of objects that restrict performance such as: Buildings Trees Rooftop objects such as air conditioning and heating HVAC units; Reflective surfaces
50 of 60
9.3 Site Preparation During the site visit, be sure to record all installation requirements including taking pictures of the site. It will be necessary to determine the following:
Other equipment in the area which can potentially interfere with the E-Band radios Ability to install the E-Link radios. Pole with a diameter between OD of 2.25 – 4.5 inches for mounting E-Link and Antenna and meet ANSI Schedule 40. A mast or tower mount exists and is there sufficient room clearance to install the unit The mast or tower has the ability to withstand wind load due to mounting of the E-Link Radio Unit + Antenna without deflecting more 1 degree from vertical. Permits that may be required Documentation required by building or site owner/landlord. Obstructions, such as tree growth or new buildings that may be a problem in the future.
The tributary, power, and alarm cables may have to penetrate the outside wall and terminate on customer supplied equipment located inside the building. Determine the following:
Cable distance between E-Link, network equipment, and the distance to the DC power source. Location of building penetration point drainage or service openings, elevator service sheds, other rooftop openings, or a new penetration through an outside wall. Size diameter of hole at the building access point. Check for other cables and clearance for E-Link cables.
Location of the nearest AC power outlet if AC to -48 VDC Power Supply is used for powering the radio: a. Location of the nearest ground bar or ground plane bus b. Power backup, such as Uninterruptible Power Supply UPS c. Location and ease of access to wiring closets
51 of 60
d. Location and ease of access of network equipment switch, router, etc e. Grounding points for lightning arrestors and cable shields at building entry point f. Locations and grounding points for surge protectors. g. Check local electrical codes for requirements for lightning rods. h. If possible, ensure that the E-Link installation is lower in height than the existing lightning rods Note: Record all installation requirements, including cable lengths, GPS co-ordinates elevation, latitude, longitude and distance between the sites.
