Tip 3
■
Important factors that reduce the radio range:
– Metal partitions or hollow walls with fiberglass
insulation on metal foil
– False ceilings with panels made of metal or carbon
fiber
– Steel furnishings or metal-coated glass
– Switch mounted on a metal wall
(typically 30 percent loss in range)
– Use of metallic switch plate series
(typically 30 percent loss in range)
■
Fire walls, elevator shafts, stairwells and supply
areas should be regarded as barriers.
■
Barriers can be removed from the radio shadow
by repositioning the transmitting and/or receiving
antenna – or by using a repeater.
Tip 4
Based on experience with practical applications, unfa-
vorable conditions and all typical shortcomings must be
planned for. Planning a range radius of 10 ‒ 12 m pro-
vides adequate safety – even if common changes to the
ambient conditions are made later on (lightweight walls,
furnishings, people in the room, etc.). Due to the reserve,
one meter more or less hardly matters when it comes to
positioning the gateway as well as during later execution.
Tip 5
An extremely robust wireless system can be created by
implementing a redundant radio reception path. This
can be achieved by programming two adjacent wireless
gateways for parallel reception of a wireless transmitter.
Tip 6
Even with careful planning, range tests using a field
strength test instrument should be carried out on site
during installation. Unfavorable conditions can be im-
proved by suitably repositioning the device (antennas) or
by using a repeater.
