Together with introduction of 5th generation (5G) of mobile communication system the millimetre wave (mmWave) frequency range is started to be utilized for personal mobile communication. Small cells deployment is typically assumed for mmWave as well as beamforming and beam steering of antenna radiation pattern. All this together enforce updates in current approaches for evaluation of radio frequency (RF) exposure, which were established and optimized for legacy systems. This paper proposes updates of simplified evaluation methods determined by International Electrotechnical Commission (IEC) for radio equipment working in frequency range between 2 GHz and 100 GHz covering mmWave. Proposed updates allow to improve the accuracy of simplified evaluation of compliance distances from mmWave small cell antennas which are capable to perform beamforming and beam steering.
