6.11 Safety exposure levels

6.11.1 Standard Applicable: FCC 15.319(i) & RSS—102 Section 4

UPCS devices are subject to the radio frequency radiation exposure requirements specified in FCC
parts 1.1307 (b), 2.1091 and 2.1093, as appropriate. All equipment shall be considered to operate in
a "general population / uncontrolled environment. For portable devices tests according to IEEE 1528
are requested, if applicable.
RSS—102 Section 4 and IC Safety Code 6, Section 2.2.1 (a) A person other than an RF and
microwave exposed worker shall not be exposed to electromagnetic radiation in a frequency band
listed in Column 1 of Table 5, if the field strength exceeds the value given in Column 2 or 3 of Table
5, when averaged spatially and over time, or if the power density exceeds the value given in Column
4 of Table 5, when averaged spatially and over time.

MPE calculation:


The EUT is considered as a mobile device according to OET Bulletin 65, Edition —97—01. Therefore
distance to human body of min. 20 cm is determined.


The limit of Power density for General Population / Umcontrolled Exposure is 1.0 mW/cm*.
Formula:


                    S = EIRP / 4tR*


Calculation:


               EIRP                Radiated Power (dBm)                                    19.75
               EIRP                 Radiated Power (mW)                                    94 .4
                R                        Distance (cm)                                      20
                S                 Power Density (mW/cm*)                                  0.0188


The Pd at 20 cm distance calculated from the Friis transmission formula is mush smaller than the
limit requirement 1 mW/cm* or 10W/m* .


The Installation Manual instructs the user to install the device such that it has a separation of at
least 20 cm from persons to comply with the FCC‘s requirements. This separation of 20 cm more
than meets the FCC‘s and Industry Canada RF exposure requirements.
