3. RF EXPOSURE MEASUREMENT
3.1 INTRODUCTION

Human exposure to RF emissions from mobile devices (47 CFR §2.1091) may be evaluated based on the MPE
limits adopted by the FCC for electric and magnetic field strength and/or power density, as appropriate, since
exposures are assumed to occur at distances of 20 cm or more from persons.


The 1992 ANSI/IEEE standard (See Listed limit table) specifies a minimum separation distance of 20 cm for
performing reliable field measurements to determine adherence to MPE limits.


If the minimum separation distance between a transmitter and nearby persons is more than 20 cm under
normal operating conditions, compliance with MPE limits may be determined at such distance from the
transmitter. When applicable, operation instructions and prominent warning labels may be used to alert
the exposed persons to maintain a specified distance from the transmitter or to limit their exposure
durations and usage conditions to ensure compliance.


                                                                               Report No.: AGC07B130101F7
                                                                                                Page 6 of 8

  for mobile and portable transmitters. See 47 CFR §§2.1091 and 2.1093 on source-based time-averaging
  requirement for mobile and portable transmitters.
