2.3 Preparing for installation
The following are general considerations and preparations that should
be looked at before installing the SpotCell 100.
2.3.5 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.
2.3.6 DDU Height
In fringe or densley built-up areas, locating the DDU as high as possible
will provide optimal performance.
2.3.7 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.
2.3.8 Proximity to power source
The indoor unit must be located within 20 feet of a power source.
2.3.9 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
cable, may be inserted, to a maximum of 50 meters total length.
