- This document focuses on applications using two utility poles. The use of two utility poles is typical for a ‘right-of-way’ (ROW...
- There are 4 elements to an installation, 1) infrastructure installation, 2) HPCU and ARU installation, 3) DU alignment and system optimization and 4) installation completion.
- Because utility pole installations often do not have AC power available at the pole, the infrastructure work is usually greater ...
- However for locations where the repeater location is uncertain, the performance at two or more locations may wish to be checked and compared before any installation work starts.
- 3.1.1 Aerial Cable vs. Buried Cable
- 3.1.2 ROW Infrastructure Installation
  - Includes:
3.2 Performance Factors
- The following should be considered when installing a SpotCell system.
- 3.2.1 Mounting Height
- 3.2.2 Signal Strength
  - The SpotCell system brings signals from an area of adequate coverage to an area with poor or non-existent coverage. It is the DU which captures a good signal, and the HPCU that provides the signal to the area with poor cell phone coverage.
  - Note: For maximum coverage, a receive signal strength (RSS) of - 85-dBm at the DU or higher is preferred. Although, not all installations require maximum coverage a RSS below -90-dBm is NOT recommended.
- 3.2.3 Unwanted Obstacles
  - General placement of the DU and HPCU must be in unobstructed areas. Neither the front of the DU or the front of the HPCU should ...
- 3.2.4 Power Source
  - To reduce cost the SC612 repeater should be close to a suitable AC power source. If this is not practical, install a solar power system.
- 3.2.5 Azimuth Differential
  - Although ideally the DU and HPCU should face in opposite directions, i.e. a back to back configuration and azimuth differential of 180-dg. an azimuth difference between the two units of 90-dg or greater is recommended.
- 3.2.6 Wanted Obstacles
- 3.2.7 Aerial or Direct Bury Cable
3.3 Approved Installation Methods
- When planning an installation, consult the Carrier for approved installation methods. When arranging for the use of utility poles the Carrier and utility company will have developed a set of approved methods. Such methods may define:
3.4 Geographic Coordinates and Azimuth
- The Carrier will specify the existing utility poles to be used. The general location may be defined using town names and street ...
- Geographic coordinates are needed as not all streets or roads are named or numbered, and poles do not have addresses. Also the Carrier’s engineering database uses geographic coordinates.
- Latitude and longitude coordinates have 3 parts - Latitude, Longitude and Datum. UTM coordinates have 4 parts - Northing, Easting, UTM Zone and Datum. UTM coordinates permit fast map location.

PERFORMANCE CONSIDERATIONS adding coverage to street and highway routes where coverage was previously not provided, such as down in a dip in the road for example. There are 4 elements to an installation, 1) infrastructure installation, 2) HPCU and ARU installation, 3) DU alignment and system optimization and 4) installation completion. Because utility pole installations often do not have AC power available at the pole, the infrastructure work is usually greater than for a roof-top application.

installed such that the Carrier specified ground clearance and power line separation distances are strictly observed. Figure 3.1 shows an aerial cable installation c/w the ARU mounted on an optional new stub pole. Alternatively the ARU would be mounted on the HPCU support pole where permitted by the utility pole owner. Other installations will use direct bury type coaxial cable . - see Figure 3.2. Figure 3.2 Buried cable c/w ARU Stub Pole Said cable may be direct buried or installed in duct below grade.

PERFORMANCE CONSIDERATIONS 3.1.2 ROW Infrastructure Installation Includes: 1. Site acquisition. 12 2. New pole installation (if required). 3. New electrical service installation (if required). 4. Grounding network preparation. 5. DU and HPCU support pipe installation. 6. Installation of conduit or duct for the coaxial cable (as required).
PAGE 23
3.2 Performance Factors The following should be considered when installing a SpotCell system. 3.2.1 Mounting Height Locating the DU as high as possible often provides a better connection to the service pr ovider’s PCS basestation. A DU mounting height above 18-ft above ground level (AGL) is recommended. L o c a t i n g t he H P C U a t a h i g h h e i g h t a l s o u s u a l l y i mp r o v e s coverage. The standard ARU to HPCU cable is 40-ft in length.
PAGE 24
PERFORMANCE CONSIDERATIONS apparatus such as transformers on utility poles or HVAC equipment found on building rooftops may also degrade performance. 3.2.4 Power Source To reduce cost the SC612 repeater should be close to a suitable AC power source. If this is not practical, install a solar power system. 3.2.5 Azimuth Differential Although ideally the DU and HPCU should face in opposite directions, i.e. a back to back configuration and azimuth differential of 180-dg.
PAGE 25
3.2.7 Aerial or Direct Bury Cable Standard cable for the SC612 is RG-11. When ordering from Spotwave be sure to inquire about the cable installation type preferred. Note: Some Carriers prefer that cable installed below grade be placed within a conduit, duct or poly-pipe to simplify replacement and protect against ground freezing. Aerial cable requires an integrated steel support wire for hanging the cabl e bet ween ut il it y poles. Al ternati vel y cabl e may be installed in steel supported duct.
PAGE 26
PERFORMANCE CONSIDERATIONS 3.3 Approved Installation Methods When planning an installation, consult the Carrier for approved installation methods. When arranging for the use of utility poles the Carrier and utility company will have developed a set of approved methods. Such methods may define: 1. Procedures for contacting and coordinating work with local Carrier or Utility personnel. 1. Minimum separation distances between SpotCell equipment and high voltage electrical lines. 16 2.
PAGE 27
3.4 Geographic Coordinates and Azimuth The Carrier will specify the existing utility poles to be used. The general location may be defined using town names and street addresses, but the specific location is defined using geographic c o o r d i n a t e s . GP S a c c u r a c y i s t o a r e s o l u t i o n o f 3 0 - f t . P o l e numbers will also usually be provided.

3.4.6 Azimuth (Bearing) The azimuth of a DU or HPCU is the direction that it points. It is given in degrees East (clockwise) from True North. True North is typically several degrees different from Magnetic North. This is called magnetic declination. It varies by location and changes a small amount each year. The Carrier typically gives you the Azimuth in degrees relative to True North. This doesn’t help if you want to align the HPCU using your magnetic compass. and you don’t know what the declination is.

Otherwise bond the ground wire to an ARU ground rod installed at the base of the ARU support. For addition details see the Grounding Note below. Note: If the grounding infrastructure work was not done earlier, contact the Carrier to confirm ground wire size and type, and the grounding network requirements for both the HPCU and DU.
PAGE 37
4.3 HPCU Installation 1. Fasten the HPCU mount to the HPCU mounting pipe at the Carrier specified mounting height, using the provided clamps - see Figure 4.6 (same mounting hardware for both the HPCU and the DU). Figure 4.6 HPCU and DU Pipe Mount Using a magnetic compass orient the mounting bracket so that when the HPCU is attached it will be aimed at the Carrier specified azimuth. Provide for the angular difference between True North and Magnetic North. When aimed correctly tighten the pipe clamp. 2.
PAGE 38
INSTALLATION 4. Connect the HPCU coaxial cable (the 40-ft cable with green boots) to the green RF port on the underside of the ARU cabinet - see Figure 4.7. A drip loop in the coaxial cable is needed if the cable at the back of the HPCU does not slope down from the HPCU. Maintain a minimum bend radius of 3-in. A drip loop is shown on the right in Figure 4.7. Figure 4.7 ARU to HPCU Cable and Drip Loop Include slack for minor alignment adjustments.

DISPLAY INFORMATION LED IS YELLOW: the captured signal is within range and the system will function, but the DU is NOT aligned to capture the strongest signal available at its current location. NOTE: the service provider (Carrier) may specify that the DU be aligned to a basestation site (azimuth) that does not produce the strongest signal. LED IS GREEN: during the second rotation of the DU this indicates that the DU is nearly optimally aligned for the current location.

labelled as back-off on the LCD Display 2. Back-off is displayed in dB units. When isolation is high, ACT RSS is high, ALT RSS is not excessive and fading is minimum, and isolation is adequate - the adaptive algorithm will deliver rated output power. However, maximum coverage will be delivered, if and only if, the installer has located and oriented the HPCU such that it provides the coverage where it is needed.
