FCC RF Exposure evaluation for mobile devices
   Devices operating in standalone mobile device exposure conditions may contain a single transmitter or multiple
   transmitters that do not transmit simultaneously. A minimum test separation distance ≥ 20 cm is required
   between the antenna and radiating structures of the device and nearby persons to apply mobile device
   exposure limits. The distance must be at least 20 cm and fully supported by the operating and installation
   configurations of the transmitter and its antenna(s), according to the source-based time-averaged maximum
   power requirements of § 2.1091(d)(2). In cases where cable losses or other attenuations are applied to
   determine compliance, the most conservative operating configurations and exposure conditions must be
   evaluated. The minimum test separation distance required for a device to comply with mobile device exposure
   conditions must be clearly identified in the installation and operating instructions, for all installation and
   exposure conditions, to enable users and installers to comply with RF exposure requirements. For mobile
   devices that have the potential to operate in portable device exposure conditions, similar to the configurations
   described in § 2.1091(d)(4), a KDB inquiry is required to determine the SAR test requirements for
   demonstrating compliance.
   When a device qualifies for the categorical exclusion provision of § 2.1091(c), the minimum test separation
   distance may be estimated, when applicable, by simple calculations according to plane-wave equivalent
   conditions, to ensure the transmitter and its antenna(s) can operate in manners that meet or exceed the
   estimated distance. The source-based time-averaged maximum radiated power, according to the maximum
   antenna gain, must be applied to calculate the field strength and power density required to establish the
   minimum test separation distance. When the estimated test separation distance becomes overly conservative
   and does not support compliance, MPE measurement or computational modeling may be used to determine the
   required minimum separation distance.
   According to §1.1310 Radiofrequency radiation exposure limits, paragraph (e), the limits for Maximum
   Permissible Exposure (MPE) to radiofrequency electromagnetic fields are:

FCC MPE Evaluation Results
   Each supported transmission technology will be evaluated to determine if it is in compliance with limits for
   Maximum Permissible Exposure (MPE) to radiofrequency electromagnetic fields.

   In order to perform the assessment, the following equations have been used for the calculations; these
   equations are accurate in the far-field of an antenna and will over-predict power density in the near field, where
   they could be used for making a "worst case" or conservative prediction:

                                               PE .I .R.P. [mW ]
   Power density: S[mW / cm 2 ] 
                                                4R[cm]2

                                                                    PE .I .R.P. [mW ]
   Minimum compliance distance: R min [cm] 
                                                                   4S[mW / cm 2 ]

   Where:
    S = power density
    PE . I . R.P. = Equivalent isotropically radiated power
    R = distance to the center of radiation of the antenna (evaluation distance)
    Rmin = distance to the center of radiation of the antenna

   The minimum use distance is greater than general population exposure minimum compliance distance.

ISED MPE Evaluation Results
   Each supported transmission technology will be evaluated to determine if it is in compliance with RSS-102
   Issue 5, RF Field Strength Limits for devices used by the General Public.

   In order to perform the assessment, the following equations have been used for the calculations; these
   equations are accurate in the far-field of an antenna and will over-predict power density in the near field, where
   they could be used for making a "worst case" or conservative prediction:



                                          PE .I .R. P.[W ]
   Power density: S [W / m 2 ] 
                                          4R[m]2
                                                              PE . I . R. P. [W ]
   Minimum compliance distance: Rmin [ m] 
                                                             4 S [W / m 2 ]

   Where:
    S = power density
    PE . I . R.P. = Equivalent isotropically radiated power
    R = distance to the center of radiation of the antenna (evaluation distance)
    Rmin = distance to the center of radiation of the antenna
