2.1 RATIONALE FOR ASSESSMENT OF THE RF EXPOSURE
The aim of the assessment report is to evaluate the compliance boundary for a set of given input
power(s) according to the basic restrictions (directly or indirectly via compliance with reference
levels) related to human exposure to radio frequency electromagnetic fields.
The chosen assessment method to establish the compliance boundary in the far-field region is
the reference method as defined in the relevant specifications.
The RF exposure assessment is based upon the following criteria:
The SenseAnywhere ClimateSensor operates with the following transmitters active on the
antenna ports shown in Section 1.3.3. For each transmitter, the Radio Access Technology (RAT),
EIRP inclusive of antenna gain and duty cycle, gain of the antenna and lowest frequency of
operation are shown as they contribute to the calculation of S Field, E field and H field values
according to the following formulas.
