5.0 WHAT ARE THE BASIC INFLUENCING FACTORS?
Regardless of the transmission procedure, radio transmission is subject to various
environmental factors which can disrupt or hinder transmission. Device characteristics
can also have an effect on range.
What does range depend on?
• Transmission power
• Antennas
• Sensitivity of receiver
• Environment (air humidity, temperature, external interference)
• Installation site
• Frequency
Structural environment (walls, ceilings etc.)
Transmission range can also be limited by obstacles. The table below provides
approximate values:
Material Energy penetration
Wood, plaster, plasterboard 90-100 %
Brick, chipboard 65-95 %
Reinforced concrete (transmitter on metal) 10-70 %
Metal, metal lattice, aluminium laminate,
under floor heating
0-10 %
