1             General information
The test results presented in this report define compliance boundaries for maximum power configurations of Radio 4415.
Outside these compliance boundaries, the radio frequency (RF) exposure levels are below the international exposure
limits specified by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) [4], the European
Commission [5], [6] and the Federal Communications Commission (FCC) [7], and Health Canada [8]. The tests were
performed by calculations in accordance with the Ericsson RF exposure calculation procedure for base stations [10],
which is in conformity with the European standards EN 50385 [2], EN/IEC 62232:2017 [3], and FCC OET Bulletin 65
[9].

Recommended product specific EMF health and safety information for Ericsson radio products is found in [1]. By
inclusion of the test report summary in [1] and the content of Appendices A and B in the product documentation, the
tested equipment complies with the documentation requirements listed in the clause 8 of EN 50385 [2].


2             Equipment under test
Table 1 and Table 2 below summarize the technical data for the equipment under test (EUT) and the antenna properties
for the integrated antenna. The tested antenna is a directional sector antenna.

Table 3 lists the nominal output power from the radio unit (total power from all antenna branches) and the total power
delivered to the antenna for the specified configuration. The total power delivered to the antenna includes a tolerance of
0.6 dB and a transmission loss of 0.5 dB.

3                  Exposure conditions

The EUT is intended to be installed on roof-tops, masts, towers, buildings, and similar structures making it possible to
ensure that the general public has no access to the EMF compliance boundary. Other installation related exposure
conditions are not reasonably foreseeable for the EUT.

The assessments were conducted for maximum power configurations, i.e. by assuming 100% utilization and
beamforming without taking time-averaging into account. Effects of real RBS utilization (time-averaged) is reasonably
foreseeable and will significantly reduce the time-averaged power and the RF exposure. This factor was not considered
in this assessment, which adds to the conservativeness of the obtained compliance boundaries.


4                  Calculations
The RF exposure was evaluated using calculations performed according to the Ericsson RF Exposure Calculation
Procedure for Base Stations [10], which conforms to EN/IEC 62232:2017[3]. The calculations were made using the far-
field spherical formula and the cylindrical wave model. The first step in calculating the compliance boundary was to use
the spherical far-field formula to estimate power density:

                                                                                  𝑃a𝐺(πœƒ,πœ™)
                                                                    𝑆sph(πœƒ,πœ™) =                 ,
                                                                                     4πœ‹π‘Ÿ2

where 𝑆,𝑃a, 𝐺, π‘Ÿ,πœƒ, and πœ™ denote the power density, the power accepted by each antenna port, the antenna gain per port,
the distance from the antenna, and the angular variables in a spherical coordinate system, respectively. The gain for each
of the four antenna ports was obtained from far-field measurements provided by the antenna manufacturer.

The accepted power per port was taken as the total power delivered to the antenna, including tolerances, divided by the
                                                                   [       πœ‹πœ‹

number of ports. In the frontal hemisphere (πœ™ ∈ β€’ 2,2 ), the exposure from antenna ports with the same nominal
polarizations (denoted ±45) were summed in a correlated way to consider beamforming while the exposure from antenna
ports with different nominal polarizations were summed in an uncorrelated manner. Also, in the rear hemisphere
             πœ‹πœ‹

If the spherical far-field formula is applied in the near-field, very conservative results may be obtained. Within the main
beam direction, a better approximation of the spatial peak power density per antenna is in this case obtained by using the
cylindrical wave model5 [11]

The cylindrical wave model is applicable within the main beam for β€’ /6 ο‚£πœ™ ο‚£ β€’ /6 and |𝑧| ο‚£ 𝐿/2 (where z is the
axis defined along the height of the antenna) and it is more accurate in the near-field regions where the spherical model
is conservative. Therefore, within this angular range in the horizontal plane, the compliance distance is taken as the lesser
of the values obtained by the two models [10].

5           Results
A box-shaped compliance boundary is used, characterized by its width, height, and the compliance distances behind and
in front of the back plane of the antenna, see Figure 1. Outside of this box, the RF exposure is below the exposure limits.

If the spherical far-field formula is applied behind the antenna, very conservative results are obtained. Given the relatively
large distance from the antenna array elements to the back of the antenna, and based on extensive experience from a large
set of numerical EMF tests for products and antennas with similar geometrical configurations and power levels [1], it is
possible to state that the compliance distance behind the antenna measured from its back plane is less than 0.1 m. This is
also confirmed by applying the SAR estimation formula for the back direction [9],

where 𝐷10g = 0.005 m ⋅ kg , 𝐷1g = 0.01 m ⋅ kg , and 𝑃tot and 𝑁e denote the total accepted power by the antenna
and the number of dual-polarized antenna elements. The distance 𝑑 is measured from the antenna ground plane. At a
distance of 0.1 m, the 10g SAR estimation formula gives SAR10g(0.1 m, 162 W, 28) = 0.29 W/kg, which is well below
the ICNIRP limits of 2 W/kg and 10 W/kg for general public and occupational exposure, respectively [4] . At a distance
of 0.1 m, the 1g SAR estimation formula gives SAR1g(0.1 m, 162 W, 28) = 0.58 W/kg. This value is well below the
exposure limits of 1.6 W/kg and 8 W/kg for general public and workers exposure applicable in both the U.S. and
Canada , respectively [7], [8].

6            Uncertainty

The input parameters were chosen within their range so as to maximize the calculated compliance boundary dimensions.
With the accepted power taken as the total power delivered to the antenna including tolerances, and the upward rounding
of compliance boundary dimensions to the nearest decimeter, the specified results are conservative.

The fact that effects of RBS utilization and time-averaging were not included in this assessment also adds to the
conservativeness of the obtained compliance boundary dimensions.


7            Conclusions
The results in Section 5 show the compliance boundary dimensions for the considered configuration when tested
according to the European standards EN 50385 [2], EN/IEC 62232:2017 [3], and FCC OET Bulletin 65 [9]. Outside of
this compliance boundary, the exposure is below the exposure limits [4], [7], [8]..

By inclusion of the test report summary and the content of Appendices A and B in the product documentation, the tested
equipment complies with the documentation requirements of EN 50385. The tested equipment complies with the
requirements in respect of all parameters subject to the test.

         Appendix A. Guidelines on how to install the product

The antenna connected to Radio 4415 (KRC 161 635/1, KRC 161 635/2, KRC 161 760/3, KRC 161 769/3, KRC 161
771/2) shall be installed to make sure that the general public does not have access to the applicable RF EMF compliance
boundary. The compliance boundary dimensions were determined for the product transmitting in free space for at least
one typical configuration. To consider possible contributions from ambient sources (e.g. other RBS products already
present on site) or the influence from any reflecting or scattering objects in the vicinity of the product installation, the
requirements in EN 50 401 [12] apply.


                                                                                                                      13 (13)

         Appendix B. Guidelines for workers during installation,
         maintenance, and repair of the product
For Radio 4415 (KRC 161 635/1, KRC 161 635/2, KRC 161 760/3, KRC 161 769/3, KRC 161 771/2), it is normally
possible to work behind the RBS antenna without any restrictions related to RF EMF exposure if the product is installed
so that contributions from other ambient sources (e.g. other RBS products) are not significant and may be neglected. If
work needs to be performed within the compliance boundary applicable for workers, the radio equipment shall be powered
off, or the power be reduced to a level ensuring that the RF EMF exposure is below the relevant exposure limit for
workers. To consider possible contributions from ambient sources (e.g. other RBS products already present on site) or
the influence from any reflecting or scattering objects in the vicinity of the product installation, the requirements in EN
50 401 [12] apply.

If work is conducted on behalf of Ericsson, minimum EMF related requirements are provided in [13].
