4.0 What are the factors to look out for?
Regardless of the method, radio transmission is subject to a range of outside factors
which can impede it or interfere with it. Equipment characteristics can also influence
the range.
Upon what is the range dependent?
• Transmission output power
• Antennas
• Sensitivity of receiver
• Environment (air humidity, temperature)
• Position of installation
• Frequency
• Structural surroundings (walls, ceilings, etc.)
Transmission range can also be limited by obstacles. The following table provides
some guidelines:
Material Energy transmittance
Wood, plaster, plasterboard 90–100 %
Brick, particle board 65–95 %
Reinforced concrete (transmitter on metal) 10–70 %
Metal, metal mesh, aluminium cladding,
underfloor heating
0–10 %
