Radio link possible?
Distance between devices is more than 400 m. No
Line-of-sight link between devices that are
about 200 m apart. Devices have been
optimally installed and configured.
Yes
Two plaster or brick walls are located between
the devices; distance between devices is
around 30 m.
Yes. Links are also possible
without line of sight, but the
range is substantially reduced,
depending on the obstacle (e.g.,
a wall).
A fire protection wall or a steel-reinforced
concrete ceiling is located between the devices.
No. Reinforced concrete and
other similar materials cannot
be penetrated by radio waves
when they are too thick.
The devices are located less than 50 m apart in
a plant building, with the line of sight being
obstructed by numerous machines or vehicles.
Possible. Building ceilings or
other metallic or steel-reinforced
large objects may permit an
indirect link by reflecting the
radio waves.
