       B.7        RF Exposure
       Limits

         FCC part                                                 Limits
                        Regardless of the power density levels permitted under this section, devices operating
                        under the provisions of this section are subject to the radiofrequency radiation
                        exposure requirements specified in §§1.1307(b), 2.1091 and 2.1093 of this chapter,
                        as appropriate. Applications for equipment authorization of devices operating under
        15.255 (g)
                        this section must contain a statement confirming compliance with these requirements
                        for both fundamental emissions and unwanted emissions. Technical information
                        showing the basis for this statement must be submitted to the Commission upon
                        request.
                        (b) For purposes of this section, a mobile device is defined as a transmitting device
                        designed to be used in other than fixed locations and to generally be used in such a
                        way that a separation distance of at least 20 centimeters is normally maintained
                        between the transmitter's radiating structure(s) and the body of the user or nearby
                        persons. In this context, the term “fixed location” means that the device is physically
                        secured at one location and is not able to be easily moved to another location.
                        Transmitting devices designed to be used by consumers or workers that can be easily
                        re-located, such as wireless devices associated with a personal computer, are
          2.1091
                        considered to be mobile devices if they meet the 20 centimeter separation
                        requirement.
                        (c)(2) Unlicensed personal communications service devices, unlicensed millimeter
                        wave devices and unlicensed NII devices authorized under §§15.253(f), 15.255(g),
                        15.257(g), 15.319(i), and 15.407(f) of this chapter are also subject to routine
                        environmental evaluation for RF exposure prior to equipment authorization or use if
                        their ERP is 3 watts or more or if they meet the definition of a portable device as
                        specified in §2.1093(b) requiring evaluation under the provisions of that section.
                        (e) Table 1 below sets forth limits for Maximum Permissible Exposure (MPE) to
                        radiofrequency electromagnetic fields.

                         3. Evaluation Methods
                         (…) Devices operating above 6 GHz regardless of the separation distance shall
                         undergo an RF exposure evaluation.

                         4. Exposure Limits
                         For the purpose of this standard, Industry Canada has adopted the SAR and RF field
                         strength limits established in Health Canada’s RF exposure guideline, Safety Code
                         6.

       Test procedure
       For the purpose of this evaluation, a minimum distance of 20cm was used to calculate the equivalent
       plan wave power density based on the Average EIRP values obtained in B.2, to be compared with the
       power density limit, according to following formula:

                  ‫ = ܩ‬Gain of the Transmitting Antenna.
                  ܴ = Distance from the Transmitting Antenna, in meters.
