The following conditions may result in a
reduced range:
- Signal transmission through building
structures or vegeta tion.
- Interference from TVs, computer
monitors and mobile phones.
Under certain circumstances, this
may prevent the receiver from func-
tioning at all.
- Positioning of the transmitter at an
unfavourable distance from surfa-
ces which reflect radio waves, for
example floors and walls.
This may lead to the signal wave
being weakened 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 may be many other sources
of radio waves which can disrupt
the original signal.
- Having units operating at similar
frequencies located close to one
another may also result in mutual
interference.
