12. Tips and Notes

Ranges and disturbances
• The product works in the 868MHz range which is also used by other radio services. This
is why there may be a restrictive operation and range due to devices that work on the same
or a neighboring frequency.
• The specified range of up to 100m is the so-called free field range, i.e. the range within
visible contact between the transmitter and receiver. But in practice, walls, ceilings etc.
between the transmitter and receiver may affect and reduce the range.
Other causes for reduced range:
• High frequency interferences of all sorts
• Any kind of housing and vegetation
• Cables and conductive metal parts which are located near the devices or within or near their
transmission path, e.g. heaters, metallized insulation glass windows, reinforced concrete
ceilings etc.
• There is an influence on the radiation pattern of antennas due by the distance from
transmitter or receiver 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 no longer be recognized due to this "noise".
• Interference radiation resulting from insufficiently shielded electronics e.g. turned on
computers or the like.
