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 Iridium Core 9523N voice and data satellite transceiver module 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. The power flux (S Field): PG ( ,  ) S 4r 2 The electric field strength (E Field): 30 PG ( ,  ) E r The magnetic field strength (H Field): E H   o Where: P = Average Power (W) G = Antenna Gain (dBi) r = Distance (cm) or (m) o = 377 Document 75932207 Report 02 Issue 2 Page 10 of 13

2.2 TEST RESULT DETAILS The frequencies shown in the tables below have been chosen based on the lowest possible frequency that the EUT can transmit.
