Guaranteed rectangular footprints can also be calculated

with the footprint calculation tool (available on the docu-

mentation CD-ROM).The given values are for one radia-

tor only, and therefore do not take into consideration the

beneficial effects of overlapping footprints. The beneficial

effects of reflections are also not included.

As rule of thumb can be given for systems with up to 4

carriers, that if the receiver can pick up the signal of two

adjacent radiators the distance between these radiators

can be increased by a factor 2.4 approximately (see figure

2.22).

2.4.2 Planning radiators

Use the following procedure to plan the radiators:

• Follow the recommendations in section 2.3 in order to

determine the positioning of the radiators

• Look up (in the table) or calculate (with the footprint

calculation tool) the applicable rectangular footprints

• Draw the rectangular footprints in the lay-out of the

room.

• If the receiver can pick up the signal of two adjacent

radiators in some areas, determine the overlap effect

and draw the footprint enlargement(s) in the lay-out of

the room.

• Check whether you have sufficient coverage with the

radiators at the intended positions.

• If not so,add additional radiators to the room.

• For larger systems and systems with more than 4 carri-

ers, use the Ease-IR simulation program for optimising

further the overlap effect and at the same time taking

into account the multi path effect.

See figure 2.15,figure 2.16 and figure 2.17 for examples of

a radiator lay out.

2.4.3 Cabling

Signal delay differences can occur due to differences in the

cable length from the transmitter to each radiator.In order

to minimize the risk of black spots, use equal cable length

from transmitter to radiator if possible (see figure 2.23).

Figure 2.23 Radiators with equal cable length

When radiators are loop-through connected, the cabling

between each radiator and the transmitter should be as sym-

metrical as possible (see figure 2.24 and figure 2.25).The

differences in cable signal delays can be compensated with

the signal delay compensation switches on the radiators.
