The paper presents an Adjacent Channel Interference (ACI) measuring method for Frequency Hopping (FH) radio stations using a digital spectral analyzer. The characteristics of the spectral analyzer can influence the measured value; that is why corrections are necessary. The paper proposes a measurement method which is in agreement with the signal statistics offered by the frequency hopping radio station.

Assessment of human exposure to RF signals which are rapidly variable in time and wide-banded is not yet standardized. Signals in IEEE 802.11 standards are widespread among population use due to presence of wireless local area network in everyday life. Recently, with technological advancement of real-time vector signal analyzers, a more precise exposure evaluation became achievable. However, such instruments are prohibitive and not available for
