NOTE: A transponder signal may repeated by several repeaters without
diminishing the efficiency of the network. The system is designed to handle
simultaneous reads.
4. Optimize for Network Efficiency
It is critical to verify at this stage that repeaters can actually be placed where
they have been located on the map. Checking in information gathered or
calling the site manager would be helpful at this stage to avoid having to
cancel the plan at arrival on site for installation. This includes access to attic
space or utility room, possibility to use a 20 feet cable between the repeater
and the antenna and possibility to install a power line (115 V AC).
Optimizing goal is to reduce the number of repeaters to be installed on the
site by reducing overlapping or moving repeaters to have a better coverage.
This is achieved by moving circles around the map.
While optimizing the design it is recommended to check furthermost
transponders to the repeaters (closer to the circle lines). They are the most
critical. It is recommended to check for factors that could reduce the range
(buildings, trees, height compared with repeater antenna). Refer to planning
factors table (figure 4).
It is also recommended to check lines of sight to verify the number and the
nature of obstacles between Transponders and Repeaters. For example 2
concrete buildings between a Transponder and a repeater will induce a high
risk not to receive the transponder.
NOTE: The idea is to eliminate repeaters while maintaining adequate
coverage of the transponder points.
Determining Cost Analysis.
The cost of the CellTrackIT system can be determined once the placement of
the repeaters is completed on the site map. Our sample in Figure 7 shows
that two repeaters were needed for the entire system to function properly.
Figuring total cost per point is a matter of identifying the various costs
associated with a CellTrackIT System installation.
CellTrackIT System Cost. The total CellTrackIT System cost is directly tied
to the number of repeaters used within the site. When designing the network
it becomes important that the number of CellTrackIT transceivers be
minimized.
The CellTrackIT transceiver antennas will need a bracket or possibly a metal
pipe for its installation. Depending on how each repeater is installed, the
antennas may also need brackets or metal pipe for setup.
