Important Safety Information
Warning! For your safety, beware of power lines and ensure appropriate
safety measures are maintained at all times during the installation of the
SpotCell equipment. If equipment not shipped with the SpotCell system
is to be used during installation or mounting, follow all equipment
manufacture’s instructions in proper use to ensure injury is avoided.
The DDU unit of the SpotCell 100 emits approximately the same power
as a cell phone. As with a cell phone antenna, avoid unneccessary contact
with the front of the unit after installed. Mount in a location where
people will not approach within one meter of the front of the unit.
This manual outlines installation instructions and the appendix offers
practical safety tips (see page 43 entitled ‘Safety Hints’).
If you are not sure about a safe installation, do not attempt to install it
yourself. Call a professional installer for help.

poorly, for example inside a building, or at the cell boundary.
![](/img.php?id=228518&img=bg8.png)
INTRODUCTION
2SpotCell 100, Release 1.0
The SpotCell 100 system receives signals from one or more cellular base
stations and re-transmits the signal to areas where cell phones do not
work or work poorly due to obstructions or the remoteness of the
location.

3 – Installation
3.1 Preparing for installation
The following are general considerations and preparations that should
be looked at before installing the SpotCell 100.
3.1.1 Signal Strength
The SpotCell 100 system brings signals from an area of adequate
coverage to an area with poor or non-existent coverage. It is the DDU
which captures a good signal, and the SCU that provides the signal to
the area with poor cell phone coverage. The DDU can be mounted
inside or outside, as long as it is in an area where your cell phone works
(even if your cell phone is only marginally working). Generally, the
better your cell phone works at the location the DDU is mounted, the
better the system will perform.
3.1.2 DDU Height
In fringe or densely built-up areas, locating the DDU as high as possible
will provide optimal performance.
![](/img.php?id=228518&img=bge.png)
INSTALLATION
8SpotCell 100, Release 1.0
3.1.3 Avoid obstructions
General placement of the DDU and SCU must be in unobstructed
areas. For example, the SCU should not be placed on a wall behind any
type of furniture (behind items such as metal filing cabinets would be a
particularly poor location). Similarly for the DDU, the front of the unit
should not be directly facing any type of metal structures, which are
often found on building rooftops.
3.1.4 Proximity to power source
The indoor unit must be located within 20 feet of a power source.
3.1.5 Distance between DDU and SCU
Although you should separate the DDU and SCU as much as possible,
there are only 25 meters of cabling provided to connect the two units.
Make sure the general location of the two units is within 25 meters.
Note: An additional cable or extension, made from copper core RG6
quad shield cable, may be inserted, to a maximum of 50 meters total
length.
3.1.6 Orientation of DDU relative to SCU
If possible face the DDU and SCU in opposite directions, and back to
back. While not a requirement, some installations will perform better if
the units are positioned in this manner.
3.1.7 Barrier between DDU and SCU
The greater the physical obstruction between the DDU and SCU, the
better the performance. Dense obstructions such as brick, concrete or
metal walls are better than wooden or plaster walls.
3.2 Positioning the SpotCell 100 DDU (outward facing unit)
It may not be possible to install the DDU indoors when installing the
SpotCell 100 in remote areas. An effort should be made to install the
DDU outdoors and the DDU should be installed as high as possible
when the installation is in a remote area,
![](/img.php?id=228518&img=bgf.png)
Spotwave Wireless Inc. 9
3.2.8 Installing the DDU
Three methods of positioning the DDU (based on location) are outlined
in the following procedure. Specifically they refer to installing inside
buildings, on external walls, and on rooftops.
1. Position the DDU (but do not mount it) as close to the final desired
mounting location as possible. The SCU does not have to be in its
final location while positioning the DDU and it is usually helpful to
have the SCU near the DDU.
2. Connect the DDU and SCU with the enclosed RF cable.
3. Connect the power supply wires to the SCU by holding down the
blue tab and pushing the positive wire (marked with text) into the
positive (+) side of the connector. While still holding down the blue
tab, push the remaining negative wire (identified by no text) into
the negative (-) side of the connector. Release the tab to secure the
power supply wires.
Figure 3.1: Inserting wires in SCU to supply power
Indoors Roof External wall
While not strictly
required, it is highly
recommended the
DDU be installed
facing a window
when installed
indoors.
The SCU does not have to be in its final
position at this time, but it should not be
brought outdoors.
![](/img.php?id=228518&img=bg10.png)
INSTALLATION
10 SpotCell 100, Release 1.0
4. Plug the power supply adapter into a wall socket
5. Ensure the switch on the SCU is in the ‘Install’ position.
Figure 3.2: SCU switch location
6. To align, hold the DDU upright and:
7. As you are rotating, you will notice that the LED on the back of the
DDU will light up green, red or amber; this is normal.
Indoors Roof External wall
Rotate the face of
the DDU from left
to right in front of
the window.
If not in front of a
window, rotate the
DDU in a complete
circle.
Rotate it in a full
circle. A time of 10
seconds is
appropriate to fully
complete the
rotation.
Rotate the face of
the unit from left to
right within the
constraints allowed
by the wall.

8. Again, rotate the DDU as in step 6, this time stopping each time the
LED is green and note the direction the DDU is facing (the LED
may turn green once or multiple times). This is an indication of
the signal strength the DDU is receiving from the cellular phone
tower. The DDU should be mounted facing the direction the DDU
was pointed for the longest period of time the LED was green
during its rotation.
9. For inside installation and exterior wall mountings, it is
recommended that various walls and locations within the structure
be tested as suitable locations to position the DDU. For each
location the DDU is tested and the LED is green, the display on the
bottom of the SCU indicates the relative signal strength that the
DDU is receiving.
Figure 3.3: Displayed signal strength
Mount the DDU in the location that has the highest indicated
signal level.
Note: With some tall buildings, it may be necessary to tilt the DDU
down to get a good signal (green LED).
10. Proceed to page 15 for mounting instructions once the DDU
location has been optimized.

3.3 Choosing a location for the SpotCell 100 SCU (indoor unit)
The SCU should be optimized and mounted, after the DDU has been
optimized and mounted. Generally, the SCU should be mounted in a
location as far as possible from the DDU, while being within the area to
have improved coverage.
If mounted on a ceiling, the unit should be downward facing, and in the
center of the area requiring cell phone coverage.
If mounted on a wall, the unit should be positioned in the middle of the
area to be covered side-to-side, and off-centered slightly front-to-back,
approximately as shown below in Figure 3.4:“SCU position and signal
coverage.”. The unit should be mounted as high on the wall as possible.
Figure 3.4: SCU position and signal coverage.
3.3.11 Positioning the SCU
1. Ensure that the DDU position has been optimized and has been
mounted in place.
2. Move the switch on the SCU from ‘Install’ to ‘Active’.
3. Hold the SCU in the position it is to be mounted. In an ideal
application, the display on the SCU will show 5 bars. If the display
is not showing 5 bars and there are alternate possible mounting
locations, move the SCU to the alternate locations and check the
![](/img.php?id=228518&img=bg13.png)
Spotwave Wireless Inc. 13
display. Place the SCU in the location showing maximum number
of bars (see Figure 3.5:“Displayed Signal Strength”). In the event the
number of bars is not changing, which is very possible, choose a
location that is most convenient.

6 – Trouble Shooting Information
1. Status: The display on the bottom of the SCU dynamically displays
information regarding the SpotCell system and environment during
installation and operation.
Action: Look at the information display to determine if the
SpotCell system is indicating a fault.
2. Status: The LED on the DDU is not illuminating during the
installation.
Action: Ensure the following:
The provided white cable is connected to the SCU and DDU.
The power supply is connected to the SCU.
The power supply is plugged into an electrical outlet.
The switch on the back of the SCU is in the ‘Install’ position.
If the LED is still not illuminating, contact technical support.
3. Status: My cell phone does not work around the location I would

4. Status: While optimizing the DDU for installation, you found that
the LED turned green in multiple locations, indicating each had
adequate signal strength. How do you determine which location is
optimal for the DDU?
Action: Look at the signal level indicated on the display on the
bottom of the SCU each time the green light appears on the DDU
during alignment. Mount the DDU in the location as indicated
having the highest signal level. Figure 6.1:“Displayed signal
strength.” below shows an example of the signal strength display.
Figure 6.1: Displayed signal strength.
5. Status: The DDU and SCU installed properly, but your cell phone
still does not work.
Action: There are three factors that may be affecting coverage as
described below:
Visually inspect the area around the SCU. Ensure that there are
not any large metallic objects directly between the SCU and the
area where cell phone coverage is not adequate. Remount the
SCU so that it is out in the open.
If the signal the DDU is receiving is very weak (although still
strong enough to allow operation), the area around the SCU
within which a cell phone can function will be relatively small.
An effort can be made to improve system performance by
raising or otherwise repositioning the DDU in an effort to
obtain a stronger signal. In Install mode, signal strength is
shown on the SCU display.
check with your cellular provider if your phone is A or B band in
800 MHz. Verify on the back of the SCU or DDU that the system
is SpotCell 100 A or B. It should be the same as your phone.
![](/img.php?id=228518&img=bg25.png)
Spotwave Wireless Inc. 31
6. Status: The coverage area around the SCU suddenly shrinks after a
long period of reliable operation.
Action: This is most likely due to man made environmental
influences such as a large building being erected somewhere in
between the DDU and the location the DDU is receiving a signal
from. Going through the install procedure with the DDU in its
current position may improve system performance (i.e. Putting the
SCU switch into ‘Install’ and spinning the DDU around twice,
aligning it in the direction indicated by the green LED on the
second spin.). If this does not help, the DDU may have to be
physically repositioned at a different location; going through the
install procedure starting at page 7 is necessary at this point.
7. Status: The SpotCell 100 has been installed and your cell phone
coverage has not improved.
Action: Check with your carrier to determine if your cell phone is a
duel band PCS/Analogue phone. If the answer is yes, and your
phone is digital, you will have to manually change the phone to
analogue while in the poor coverage area.
8. Information: Remote installation SpotCell 100 characteristics.
In order for the SpotCell 100 system to function, there are two basic
parameters that must be met. The DDU must receive a minimum
amount of cellular signal, and a physical environment that blocks
cellular signals must be in between the DDU and SCU (i.e. a wall).
If the DDU is not receiving an adequate signal, the system will not
work, or, it will work but provide a very limited area around the
SCU in which a cell phone will function. In this instance, it may be
possible that only one cell phone will be capable of using the system
at a time. This is typical of applications that are on the fringe, or
outside of a Cellular providers advertised coverage area. Improved
performance will typically only be attained by moving the DDU to
a higher location.

ROUBLE SHOOTING INFORMATION
32 SpotCell 100, Release 1.0
9. Information: Residential (or building) installations that do not
provide for brick, concrete, metal, or other dense material between
the DDU and SCU.
Action: In this situation it is possible that the signal emitted by the
DDU will be received by the SCU. This will result in the system
lowering the power of the signal it is emitting; and therefore the area
around the SCU in which a cell phone will function will become
smaller. To improve performance in this scenario, it is important to:
Maximize the height of the DDU
Separate the DDU and SCU horizontally as much as possible
Mount the DDU and SCU in a back-to-back manner.
It is recommended to use 50 meters of cable in between the
DDU and SCU if possible in an effort to vertically and
horizontally separate the system units.
10. Information: Proper alignment rotation
Action: Make sure the DDU is rotated once completely within the
area available for rotation, and then move through the same rotation
again. DDU alignment is based on optimizing the direction the
DDU is facing after initially establishing the range of signal available
by rotating the DDU in a circle. Once the DDU has been rotated in
a circle and established the level of signal available, it now sets a
threshold based on the surroundings to determine when the LED
will illuminate green. If the DDU is not pointing in a direction that
is within a certain range of the highest signal it encountered since
being in ‘Install’ mode, the LED will not turn green. Additionally,
the LED will not illuminate green if a minimum signal level is not
achieved during the initial rotation.

Appendix A – Applications overview
SpotCell 100 operates in the 800 MHz cellular frequency band, is A or
B sub-band specific, installed in a location where a cellular handset has
poor or non-existent coverage. Poor coverage may be a result of signal
degradation due to terrain or urban environmental influences such as
buildings, tunnels or underground garages. It may also be a result of
the user being in a fringe area or outside of the known existing cellular
coverage area.
The coverage area provided is typically up to 10,000 square feet (930
square metres) for an office area and up to 20,000 square feet (1,850
square metres) for an open area, and varies depending on a number of
factors.
A.1 Components and Installation
SpotCell 100 complements the existing cellular infrastructure, filling in
coverage holes in buildings within a base station coverage area.

APPLICATIONS OVERVIEW
36 SpotCell 100, Release 1.0
A.2 Operation
SpotCell 100 will be used in existing cellular networks, and will function
transparently to both the end user and the operator in terms of the
services provided by the cellular network. The adaptive algorithms
employed in SpotCell 100 allow it to be a non-engineered solution – i.e.,
installed and operated without engineering intervention or support.
SpotCell 100 operates with the following circuit-switched air interface
protocols that are used in the North American (800 MHz) cellular band:
AMPS and NAMPS (analog)
IS-136 NA TDMA
IS-95 CDMA
SpotCell 100 uses two units (DDU and SCU), each supporting full
duplex communications. The DDU is typically located outdoors, at an
elevation higher than the SCU to help reduce the path loss to the base
station. The SCU is located indoors in an area requiring improved
coverage.
The SpotCell 100 system provides a net increase in system gain between
the mobile subscriber and the base station. This gain is distributed
between the active antennas located in the Donor Unit and Indoor Unit
to maximize overall system performance and stability.
The gain is adjusted by the signal processing stages located in the Indoor
Unit to account for the local RF environment changes.
SpotCell 100 uses three main adaptive algorithms to control the system
operation. The first algorithm is used during the system installation, and
determines the position of the optimum base station that the unit
should be aligned toward. This position is presented to the installer as a
green light when the unit is being installed.
The second algorithm performs “intelligent” gain control. This
determines the minimum reliable wireless link to the base station and
the maximum coverage area that can be realized using the available
uplink and down-link gains, so that the system gain is balanced in either
direction.
![](/img.php?id=228518&img=bg2b.png)
Spotwave Wireless Inc. 37
The third algorithm works to maintain adequate isolation to
unconditionally ensure system stability at all times and therefore
preserve the integrity of the cellular network.

Appendix C – Safety Hints
Customer safety is a concern we would like to address in a sensible and
proactive manner. To this end, the following notes have been provided
as a reference to help installers remain safe and think about safety in all
aspects of the installation.
The following notes are to be considered as informational only, and not
exhaustive or complete.
C.1 Lightning
Never attempt to install the DDU outdoors while a lightning storm is
in progress in your immediate or neighboring vicinity. The National
Lightning Institute says for every five seconds between the flash of
lightning and a thunderclap, the lightning is one mile away. If lightning
is within 3 miles (15 second count between flash and thunder) of your
location, do not attempt an installation.
C.2 Working Aloft
When working aloft, it is best to work in pairs. Avoid attempting
procedures alone that are best carried out with a spotter or by two
people.

SAFETY HINTS
44 SpotCell 100, Release 1.0
C.2.1 Power Tools
Proper eye protection should be worn when using a drill or any other
type of power tool.
C.2.2 Working with Ladders
Properly secure your ladder and work in pairs. Make sure the ladder is
properly tied off and use an insulated ladder when working around
power lines.
C.2.3 Grounding
Ensuring the DDU is properly grounded in external installations will
help to prevent property damage and personal injury during lightening
storms.
C.3 Overhead Power Lines
While overhead power lines may appear to be insulated, they most likely
are not insulated. Always thoroughly investigate your surroundings prior
to installing masts or the DDU in an outdoor location.
Never attempt installation without adequate lighting, as shadows and
trees can obscure power lines.

Ranges between approximately 50 to 600
mwatts
dB The difference (or ratio) between two signal
levels. Named after Alexander Graham Bell.
(That is why the "B" is capitalized. ) Used to
describe the effect of system devices on sig-
nal strength. For example, a cable has 6 dB
loss or an amplifier has 15 dB of gai n. This is
very useful because system gains and losses
can be calculated by adding and subtracting
dBi The gain a given antenna has over a theoreti-
cal isotropic (point source) antenna. Unfortu-
nately, an isotropic antenna cannot be made
in the real world, but it is useful for calculating
theoretical fade and System Operating
Margins.
A dipole antenna has 2.14 dB gain over a 0
dBi isotropic antenna. Thus, a simple dipole
antenna has a gain of 2.14 dBi or 0 dBd.

dBm A signal strength or power level. 0 dBm is
defined as 1 mW (milliWatt) of power into a 50
ohm load such as an ante nna. Small signals
are negative numbers. This is useful since
dB shows values in a logarithmic scale, not
linear.
RULE OF THUMB: Every time you double (or
halve) the power level; you add (or subtract) 3
dB. For example, 125 mW is 21 dBm and
250 mW is 24 dBm.
Directional Donor
Unit DDU
This is the SpotCell 100 system element that
is installed with a directional antenna aimed at
the nearest cellular base-station. This unit
may often be installed outdoors. The term
donor is widely used in the repeater industry
for the antenna that supports the air interface
to the network.
Effective Radi-
ated Power
(ERP)
Effective radiated power. It is equal to the sum
of the antenna gain (in dBi) plus the power (in
dBm) into that antenna. For example, a 12
dBi gain antenna fed directly with 15 dBm of
power has an Effective Radiated Power (ERP)
of:
12 dBi + 15dBm = 27 dBm or 500mW.
Isolation RF isolation is a measure of the path loss or
attenuation between two antennas. Path loss
typically must be 15dB or higher than the
required system gain for a repeater to function
properly.
