The test results reported in this document have been obtained by simple calculations according to plane-
wave equivalent conditions [3]. The purpose of the tests was to verify that the EUT is in compliance with the
appropriate RF exposure standards, recommendations and limits [1] - [4] .

4         EMF exposure assessments

FCC procedures [3] specify exposure assessment methods to verify compliance with EMF exposure limits [1]
of mobile devices. A minimum test separation distance of at least 20 cm is required between the device and
nearby persons to apply mobile device exposure limits. The test separation distance for which the equipment
is shown to comply with the exposure limits must be clearly provided in the operating and installation
instructions.

4.1        US market – field strength calculations

The maximum gain, 𝐺ANT , of the four antenna ports used is 3 dBi (2), see Table 1. Assuming correlated
transmit signals, the directional gain, 𝐺, may be taken as 9 dBi, according to [5]. This is most likely a very
conservative assumption given the used transmission modes and antenna topology.

The total effective radiated power for the antennas is 1.14 W. As a consequence, the categorical exclusion
provision of FCC CFR title 47, § 2.1091(c) applies [6] and the minimum test separation distance may be
estimated by simple calculations according to plane-wave equivalent conditions [3].

The exposure ratio, 𝐸𝑅, may be conservatively estimated as

                                                                      𝑆est    𝑃tot 𝐺
                                                             𝐸𝑅 =          =            ,
                                                                      𝑆lim   4𝜋𝑟 2 𝑆lim

where

𝑃tot : Total conducted power for the cellular bands (23.7 dBm/0.24 W),

𝐺 : Directional gain (9 dBi),

𝑟: Separation distance from antenna

𝑆lim : Power density exposure limit of 10 W/m2.

Setting 𝑃tot = 0.24 W, 𝐺 = 7.94, 𝑟 = 0.20 m and 𝑆lim = 10 W/m2 gives the result for a 20 cm test separation
distance in Table 3.

The exposure ratio is well below one. Hence, the RF EMF exposure is below the relevant exposure limits [1]
for the 20 cm test separation distance.


4.2                  Canadian market – use of exemption limits

According to the requirements in RSS-102 [4], in the frequency range at or above 300 MHz and below 6 GHz
RF exposure evaluation is not required if the following exemption limit is fulfilled
                                                            𝐸𝐼𝑅𝑃 ≤ 0.0131𝑓 0.6834 W,
where 𝑓 is the frequency in MHz. With a total conducted power of 23.7 dBm and a maximum directional gain
of 9 dBi the maximum 𝐸𝐼𝑅𝑃 = 1.87 W, which is below the exemption limit 𝐸𝐼𝑅𝑃lim = 0.0131 ⋅ 35500.6834 W =
3.5 W. As a consequence, no RF exposure evaluation is required according to the Canadian regulatory
requirements [4].




4
  For a test separation distance of 20 cm, the exposure was found to be well below applicable exposure limits in the direction of maximum gain. Since this
test position corresponds to the direction of maximum exposure and the RDS is classified as a mobile device with an intended separation distance to the
user or nearby persons of at least 20 cm, other test positions were not considered.
5
  The separation distance is measured from the EUT casing.


                                                                                                       5 (7)
GFTB-17:001789 Uen, Rev B, 2017-11-04


5     Conclusion
The results in Section 4 show that the plane-wave equivalent power density, estimated according to the
requirements of FCC [3] is below the relevant MPE limits [1] at a separation distance of 20 cm between the
equipment and any nearby person.

The maximum EIRP has been found to be 1.87 W which is less than the applicable exemption limit for
routine evaluations of 3.5 W specified in RSS-102 [4]. As a consequence, for the Canadian market, no RF
exposure evaluation is required.

Consequently, the EUT is in compliance with the appropriate RF exposure standards and recommendations.
