Radio range
The lisa transmitters are designed to
have a radio signal range of 80 me-
ters under optimum conditions.
The following conditions may result in
a reduced range:
- Signal transmission through building
structures or vegetation
- Interference from TVs, computer
monitors and mobile phones. Under
certain circumstances, this may
prevent the receiver from functio-
ning at all.
- Positioning of the transmitter at an
unfavorable distance from surfaces
which reflect radio waves, for ex-
ample floors and walls. This may
lead to the signal wave being wea-
kened or even cancelled out by the
reflected wave.
- Metallic objects reduce the range
due to the shielding effect of the
metal.
- Particularly in towns and cities, there
maybe many other sources of radio
waves which can disrupt the original
signal.
- Having units operating at similar fre-
quencies located close to one an-
other may also result in mutual inter-
ference.
