  1. Overview of the exposimeters (ESM-140, EME SPY121) that were previously used in studies and the newly developed EME SPY 140 [23].
  2. 1combined bands for the frequency range between 880 and 960 MHz and for 1700-2200 MHz.
  3. 2Theoretical capacity taking into account the capacity of the memory component and the number of bytes to save for measurement, but may not be achieved due to battery life.
