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 %
