Verification of code-selective 5G measurements to assess the maximal RF exposure to mobile-radio base stations with dynamic spectrum sharing

The dynamic spectrum sharing technology is increasingly being used to enable parallel operation of 4G and 5G in one frequency band. 5G code-selective measurements provide a new method to assess the maximal exposure to 5G and offer an alternative to the frequency-selective method used so far. We have investigated this code-selective method and compared the maximal exposure of 5G and 4G with dynamic spectrum sharing. Theoretically, 5G and 4G should generate the same maximal RF exposure, assuming the same transmit power in the frequency band under consideration. This assumption was confirmed by measurements, so the suitability of the code-selective method for measurements at 5G base stations with dynamic spectrum sharing was proven.
