Abstract

Interfering levels are most significant to define compatibility between radio systems. Common equations calculate the threshold levels in terms of power and field-strength. These thresholds are used to protect radio services from interfering radiators, in particular, incidental radiators such as PLT, cable installations and ISM. Assuming the minimum distance from interferer to victim, the spectrum emission mask is calculated. The study provides practical values. Measurements of noise levels and interference support the calculations and provide evidence to the methodology.
