Margin / System Operating Margin Calculator
Fade margin is the difference between the strength of the
received signal at the antenna port and the minimum signal
strength in dB, determined by the manufacturer for reliable operation.
The higher the fade margin, the more
reliable the link will be. The required Fade Margin depends on
several factors including: Frequency used, link distance and
reliability requirements. For example, a 2.4GHz, ISM band
radio usually requires a minimum of 15dB fade margin. A 5GHz
ISM / UNII band radio usually a minimum of 10dB.
