10. Ranges and radio interference
• The radio transmission from the base unit to the remote sensor is possible
in the range of 433 MHz, also used by other devices. This can affect the
range and operation of the station.
• The specified range of 30 m is a free field range, i. e., a range within a line-
of-sight contact between the remote sensor and the base unit. But in
practice, walls, ceilings etc. between the transmitter and receiver may affect
and reduce the range.
Other causes for reduced range:
• Any radio frequency interference
• Any housing and vegetation
• Conductive metal parts which are located near the units or within or near
their transmission path, e. g. heaters, metallized insulation glass windows,
reinforced concrete ceilings etc.
• Influence on the radiation pattern of antennas caused by the distance from
the remote sensor and base unit to conductive surfaces or objects (to
human bodies or ground also)
• Broadband interference in urban areas which reduces the signal-to-noise-
ratio; the signal will not be recognized due to this "noise"
• Interference radiation resulting from insufficiently shielded electronics, e. g.
open computers or the like
