APPLE COMPUTER_p160703_p158393.JxReport.09142020.rev1signedCompliance Statement
Based on information provided by Verizon Wireless, predictive modeling, and data gathered during the site
visit on September 1, 2020, the Apple Computer NCA-P-160703 & NCA-P-158393 installation by Verizon
Wireless is compliant with Radiofrequency Radiation Exposure Limits of 47 C.F.R. §§ 1.1307(b)(3) and 1.1310.
Delineating areas that are predicted to exceed the FCC MPE limits with barriers/markers and RF alerting
signage have been installed. Restricting access to these areas to authorized personnel that have completed
RF safety training is also required for Occupational environment compliance. The operation will not expose
members of the General Public to hazardous levels of RF energy at ground level or in adjacent buildings.
Certification
I, David H. Kiser am the reviewer and approver of this
report and am fully aware of and familiar with the Rules
and Regulations of both the Federal Communications
Commissions (FCC) and the Occupational Safety and
Health Administration (OSHA) with regard to Human
Exposure to Radio Frequency Radiation, specifically in
accordance with FCC’s OET Bulletin 65. I have
reviewed this Radio Frequency Exposure Assessment
report and believe it to be both true and accurate to the
best of my knowledge.
General Summary
The compliance framework is derived from the Federal Communications Commission (FCC) Rules and
Regulations for preventing human exposure in excess of the applicable Maximum Permissible Exposure
(“MPE”) limits. At any location at this site, the power density resulting from each transmitter may be expressed
as a percentage of the frequency-specific limits and added to determine if 100% of the exposure limit has been
exceeded. The FCC Rules define two tiers of permissible exposure differentiated by the situation in which the
exposure takes place and/or the status of the individuals who are subject to exposure. General Population /
Uncontrolled exposure limits apply to those situations in which persons may not be aware of the presence of
electromagnetic energy, where exposure is not employment-related, or where persons cannot exercise control
over their exposure. Occupational / Controlled exposure limits apply to situations in which persons are exposed
as a consequence of their employment, have been made fully aware of the potential for exposure, and can
exercise control over their exposure. Based on the criteria for these classifications, the FCC General
Population limit is considered to be a level that is safe for continuous exposure time. The FCC General
Population limit is 5 times more restrictive than the Occupational limits.

In situations where the predicted MPE exceeds the General Population threshold in an accessible area as a
result of emissions from multiple transmitters, FCC licensees that contribute greater than 5% of the aggregate
MPE share responsibility for mitigation.
Based on the computational guidelines set forth in FCC OET Bulletin 65, Waterford Consultants, LLC has
developed software to predict the overall Maximum Permissible Exposure possible at any location given the
spatial orientation and operating parameters of multiple RF sources. The power density in the Far Field of an
RF source is specified by OET-65 Equation 5 as follows:
!= !"#$
%⋅'⋅#! (mW/cm()
where EIRP is the Effective Radiated Power relative to an isotropic antenna and R is the distance between
the antenna and point of study. Additionally, consideration is given to the manufacturers’ horizontal and
vertical antenna patterns as well as radiation reflection. At any location, the predicted power density in the
Far Field is the spatial average of points within a 0 to 6-foot vertical profile that a person would occupy. Near
field power density is based on OET-65 Equation 20 stated as
!=*180
.)*
/⋅100 ⋅1+,
2 ⋅3 ⋅ℎ (mW/cm()
where Pin is the power input to the antenna, qBW is the horizontal pattern beamwidth and h is the aperture
length.
Some antennas employ beamforming technology where RF energy allocated to each customer device is
dynamically directed toward their location. In the analysis presented herein, predicted exposure levels are
based on all beams at full utilization (i.e. full power) simultaneously focused in any direction. As this condition
is unlikely to occur, the actual power density levels at ground and at adjacent structures are expected to be
less that the levels reported below. These theoretical results represent worst-case predictions as all RF
emitters are assumed to be operating at 100% duty cycle.
For any area in excess of 100% General Population MPE, access controls with appropriate RF alerting signage
must be put in place and maintained to restrict access to authorized personnel. Signage must be posted to be
visible upon approach from any direction to provide notification of potential conditions within these areas.
Subject to other site security requirements, occupational personnel should be trained in RF safety and
equipped with personal protective equipment (e.g. RF personal monitor) designed for safe work in the vicinity
of RF emitters. Controls such as physical barriers to entry imposed by locked doors, hatches and ladders or
other access control mechanisms may be supplemented by alarms that alert the individual and notify site
management of a breach in access control. Waterford Consultants, LLC recommends that any work activity
in these designated areas or in front of any transmitting antennas be coordinated with all wireless tenants.

Analysis
Waterford Consultants, LLC field personnel visited the site on September 1, 2020 during business hours and
collected data with regard to the RF environment. All accessible areas of the site were inspected.
Measurement collection was performed using Narda Radiation meter NBM 550 and broadband probe EA-5091
(300 kHz to 50 GHz) and was consistent with FCC and Narda procedures, regarding the location of the probe
to the RF source and making slow sweeping motions over the area that a person would occupy. Power density
values were recorded as a percentage of the FCC Occupational limits. In using this broadband instrument, the
results represent the cumulative contributions of all RF sources at the measurement locations. The maximum
cumulative power density reading was 57.55% of the FCC Occupational limits (287.75% of the General
Population limits). Measurement locations and tabulated results are presented in Appendix B.
Verizon Wireless performed the following modification at this location:
• (2) NEW SBNHH-65B ANTENNAS
• (6) RRH UNITS
Antenna operating parameters are listed in Appendix A. Other appurtenances such as GPS antennas, RRUs
and hybrid cable below the antennas are not sources of RF emissions. Panel antennas have been installed
at this site by other wireless operators. Operating parameters for these antennas considered in this analysis
are also listed in Appendix A.

Figure 1: Antenna Locations
Power density decreases significantly with distance from any antenna. The panel-type antennas to be
employed at this site are highly directional by design and the orientation in azimuth and mounting elevation,
as documented, serves to reduce the potential to exceed MPE limits at any location other than directly in front
of the antennas. For accessible areas at ground level, the maximum predicted power density level resulting
from all Verizon Wireless operations is 0.1436% of the FCC General Population limits. Based on the operating
parameters in Appendix A, the cumulative power density level at this location from all antennas is 0.675% of
the FCC General Population limits. Incident at adjacent buildings depicted in Figure 1, the maximum predicted
power density level resulting from all Verizon Wireless operations is 44.3318% of the FCC General Population
limits. Based on the operating parameters in Appendix A, the cumulative power density level at this location
from all antennas is 88.6636% of the FCC General Population limits. The operations will not expose members
of the General Public to hazardous levels of RF energy at ground level or in adjacent buildings.

For accessible areas at the roof level of 2 Infinite Loop, the maximum predicted power density level resulting
from all Verizon Wireless operations is 68.084% of the FCC Occupational limits (340.42% of the FCC General
Population limits). Based on the operating parameters in Appendix A, the cumulative power density level at
this location from all antennas is 68.74474% of the FCC Occupational limits (343.7237% of the FCC General
Population limits). For areas on the roof near the antennas that are predicted to exceed the General Population
limits, barriers/markers and RF alerting signs (Caution and RF Guidelines) have been posted to be visible upon
approach to provide notification of potential conditions at these areas. These mitigation measures are depicted
in Figure 2. Any work activity in front of transmitting antennas should be coordinated with Verizon Wireless.
