The footprint of the radiator

The coverage area of a radiator depends on the number of transmitted carriers and the output
power of the radiator. The coverage area of the LBB 4512/00 radiator is twice as large as the
coverage area of the LBB 4511/00. The coverage area can also be doubled by mounting two
radiators side by side. The total radiation energy of a radiator is distributed over the
transmitted carriers. When more carriers are used, the coverage area gets proportionally
smaller. The receiver requires a strength of the IR signal of 4 mW/m
without errors (resulting in a 80 dB S/N ratio for the audio channels). The effect of the number
of carriers on the coverage area can be seen in the next two figures. The radiation pattern is
the area within which the radiation intensity is at least the minimum required signal strength.
