Important Safety Information
Warning!
For your safety, beware of power lines and ensure
appropriate separation distances, and safety measures, are
maintained at all times during the SpotCell equipment
installation. If equipment supplied by others is to be used during
installation or mounting, follow all equipment manufacturer’s
instructions to ensure injury is avoided.
If you are installing the SpotCell near high voltage power lines,
or in any way are not sure about a safe installation, do not
attempt to install it yourself. Call a professional installer for
help.
The DU and HPCU of the SpotCell are low power transmitters. As
with a cell phone antenna, avoid unneccessary contact with the
front of the units after installed. Mount the units in a location
where people will not approach within 1 meter of the front of the
DU or HPCU.

1.3 Product Overview
The purpose of the SpotCell 612 is to enable personal wireless
communications in specific locations within a wireless service
area where cell phones do not work, or works poorly, for example
along a highway right-of-way where it dips down into a valley,
coulee or draw, or the signal is obstructed by buildings or trees.
Figure 1.1 Base station signal does not reach wireless subscriber
The SpotCell system receives signals from a wireless base station
and re-transmits them to areas where cell phones do not work
well due to obstructions or the remoteness of the location.

Chapter 3 – Performance Considerations
3.1 Overview
The DU is typically attached to a utility pole or tower, a non-
penetrating roof mount support pipe, or the exterior wall of a
building.
The HPCU is typically attached to a second utility pole or tower,
a second non-penetrating roof mount support pipe, or the
exterior wall of a building. For inside building coverage the
HPCU may be wall or ceiling mounted.
This document focuses on applications using two utility poles.
The use of two utility poles is typical for a ‘right-of-way’ (ROW)
application. The goal of a ROW application is typically that of

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. Where this is the case, it would
be best to have the infrastructure work complete before the
SpotCell repeater installation begins. This permits the repeater
installers to complete the installation in one visit and in
minimum time.
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
For some installations aerial coaxial cable c/w a steel support wire
will be used. The steel support wire is attached to the pole using
Carrier recommended hardware and methods. The aerial span is

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.
Consult the Carrier with respect to the requirements for the
specific installation location.
For the vertical runs of the coaxial cable and ground wire, the
Carrier may require one or both to be strapped directly to the
pole, or installed in conduit attached to the pole. The means and
method for attaching the cable to the pole, or the conduit to the
pole may also be specifically specified by the Carrier.

Spotwave Wireless Inc. 13
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 provider’s PCS basestation. A DU
mounting height above 18-ft above ground level (AGL) is
recommended.
Locating the HPCU at a high height also usually improves
coverage. The standard ARU to HPCU cable is 40-ft in length.
The ARU is located on or adjacent to the HPCU support pole.
In addition, increasing the DU to HPCU separation distance will
increase isolation - this may also increase the coverage.
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 be directly obscured by buildings or trees. Large metal
![](/img.php?id=464415&img=bg18.png)
PERFORMANCE CONSIDERATIONS
14 SpotCell 612 Adaptive Repeater
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. an azimuth difference between the two
units of 90-dg or greater is recommended.
3.2.6 Wanted Obstacles
For a pole mounted SC612 repeater, the opportunity of selecting
pole locations in order to take advantage of a physical obstacle
between the DU and HPCU to improve RF isolation is not often
practical.
For a roof-top located SC612 this is possible and should be done.
The two units should be located on opposite exterior walls of the
building, or opposite exterior walls on the roof-top penthouse.
For the two utility pole application with no obstacle between the
poles, separate the poles 85-ft or more apart. The standard DU to
ARU cable is 164-ft in length.
Walls constructed of dense materials (concrete, brick or metal
provide high isolation. However, such walls may also be a source
of reflections and antenna pattern degradation. When locating
the DU and HPCU avoid placement where such adjacent walls are
significantly within the view of the antenna.
![](/img.php?id=464415&img=bg19.png)
Spotwave Wireless Inc. 15
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 cable between utility poles. Alternatively cable may be
installed in steel supported duct.
‘Filled’ cable is needed for direct burial below grade, i.e. not in
conduit, duct or poly-pipe. Such cable is flooded with a
petroleum compound or a dry-fill powder for protection from
water ingress.
The supply of suitable aerial and direct bury cables is limited.
Call Spotwave for availability.

16 SpotCell 612 Adaptive Repeater
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.
2.
Acceptable locations for new support poles and procedures
for approval and installation.
3.
Grounding network materials and installation methods -
ground wire, ground rod, lightning arrestor and bonding.
4.
Pole attachment methods for coaxial cables, ground wire and
SpotCell equipment (DU, HPCU and ARU), and approved
methods for aerial and direct buried cable installation.
5.
AC power equipment, solar power equipment and installation
methods.

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
coordinates. GPS accuracy is to a resolution of 30-ft. Pole
numbers will also usually be provided.
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.
3.4.1 Map Datum
The earth is not a perfect sphere. The map datum is a means for
adjusting for this. For the USA and Canada 2 map datums are
used NAD27 and NAD82. The default datum for the world is
WGS84. For the USA and Canada WGS84 and NAD83 are usually
identical.
When using coordinates to find your location on a map you need
to have your GPS receiver set to the datum that is printed on the
map that you are using.
If the Carrier provides the coordinates in a datum different from
the map datum, your GPS receiver may be used to translate them
for you. This is done by entering the coordinates as a waypoint
with the GPS configured for the datum which the carrier uses,
then reconfiguring the GPS to the map datum and then recalling
the waypoint from memory. The waypoint will then show the
coordinates as per the map datum.

Lat.: 40.63192, Long: 104.93756, Datum: NAD27
This is the same location as above but in decimal degree format.
3.4.4 UTM Coordinates
UTMs are sometimes referred to as military grid references. The
following is the same location as given above:
Northing: 4497.687, Easting: 505.300, Zone:13, Datum: NAD27
Northing is the distance in kilometers from the equator, Easting
is the distance in kilometers from the East boundary of Zone 13.
Topographic maps are divided up into 1-km squares with
Northings and Eastings labelled. Using a scale of 2-cm = 1-km any
location can be quickly and accurately plotted on the map. This
is difficult using Latitude and Longitude.
3.4.5 Topographic Map and GPS Receiver
Prior to visiting a site it is recommended that you acquire the
applicable 1:50,000 scale topographic map and become familiar
with setting your GPS receiver to NAD27 and NAD83 Datums.
![](/img.php?id=464415&img=bg1d.png)
Spotwave Wireless Inc. 19
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. However there is a method of determining the
declination using your GPS receiver.
If you know the coordinates for the basestation that the Carrier
wants the DU to be served by and the coordinates for the DU
location, your GPS will tell you the magnetic azimuth that the
DU should be aimed at, if your GPS is set for magnetic azimuths.
On this setting it automatically takes into account the magnetic
declination. So, if the Carrier specifies the azimuth for the DU to
be 90-dg relative to true North (i.e. aimed due East) but your GPS
gives you an azimuth of 100-dg magnetic. Then the declination is
10-dg.
So if the Carrier specifies that the HPCU is to be aimed at 270-dg
(i.e. due West) then you will use you compass to aim the HPCU at
an azimuth of 280-dg magnetic.
When using a compass be sure not to be close to large steel
objects or a false alignment will result.

4.4.3 Alignment Overview
This work locates and aims the DU so that for maximum coverage
potential is provided. For some installations this work may also
result in a minor HPCU alignment change being made.
A bucket truck is recommended for lifting the DU and installer up
to the proposed DU location(s). Observe all appropriate safety
measures.
4.4.4 Coverage Potential
For maximum coverage potential, a receive signal strength (RSS)
of -85-dBm at the DU or better is needed. When the RSS is weak
DU to HPCU isolation is very important. The more the DU and
HPCU approach a back-to-back orientation and/or the further the
two units are apart, the greater the isolation and coverage
potential.
4.4.5 Alignment Options
If the Carrier has specified that the DL basestation signal that the
DU is to use will be a non-dominant signal (i.e. non-dominant PN
code), then skip Section 3.5 (Dominant Alignment) and jump to
Section 3.6 (Non-Dominant Alignment).

Standard Display 1 - Active & Alternate RSS
Display 1 indicates the carrier level into the DU as measured at
the ARU. The ACTive carrier is the wanted in-band signal and the
ALTernate is the unwanted out-of-band signal level (before filter-
ing).
Standard Display 2 - Signal Quality Index & Back-Off
Display 2 confirms the quality of the installation with respect to
it’s potential to deliver rated coverage. Coverage may require the
installer to optimize the DU and HPCU locations. An optimal DU
location will deliver a strong, high quality downlink signal that
exhibits minimum fading. Success in this is indicated on the ARU
display via the Signal Quality Index or SQI on Display 2 (as
shown in Table 2 ). On the LCD, SQI is labelled as “ISOLATION
(
nn
)”. High quality downlink signals have an SQI less than 60.
An optimal HPCU location will provide coverage where it is
required while satisfying the HPCU to DU isolation need.
Where available isolation is less than the gain required to achieve
rated output power, the system gain is reduced by the adaptive
algorithm to ensure stability. The resulting gain reduction is

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. That is, located where the HPCU antenna pattern
matches the required coverage area with no significant RF dense
materials in the way.
