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:
