EME_Report_IspaceshipNCAP188579.11.30.2020signedCompliance Statement
Based on information provided by Verizon Wireless, field measurements and predictive modeling, the
Ispaceship - B installation proposed by Verizon is compliant with Radiofrequency Radiation Exposure Limits
of 47 C.F.R. §§ 1.1307(b)(3) and 1.1310. On-site measurements collected by Waterford Consultants
personnel on November 18, 2020 were found to be below 125% of the FCC General Population Maximum
Permissible Exposure (MPE) limits which is supportive of the worst-case predictive analysis. Along with
documented mitigation delineating areas that are predicted to exceed the FCC MPE limits with paint and RF
Alerting signage and restricting access to these areas being in place, this location will not expose members of
the General Pubilc to hazardous levels of RF energy at ground level or in adjacent buildings. Restricted areas
should be limited to authorized personnel that have completed RF safety training.
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
Verizon Wireless has installed the following at this location:
• The wireless telecommunication facility is located on a building rooftop. The antennas are mounted
behind the screen walls above the main roof level and connected to the equipment via coaxial cable.
Antenna operating parameters are listed in Appendix A. Measurement results from the site survey are listed
in Appendix B. Other appurtenances such as GPS antennas, RRUs and hybrid cable below the antennas are
not sources of RF emissions. No other antennas are known to be operating in the vicinity of this site.
The antennas will be mounted on a 54-foot Rooftop with centerlines 60 feet above ground level. 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. No other antennas are known to be operating in
the vicinity of this site.
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 operations is 5.3255% of the FCC General Population limits. Incident at adjacent buildings
depicted in Figure 1, the maximum predicted power density level resulting from all Verizon operations is
1.0915% of the FCC General Population limits. The proposed operation 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 1 Apple Parkway, the maximum predicted power density level resulting
from all Verizon operations is 108.718% of the FCC Occupational limits (543.59% of the FCC General
Population limits). As shown in Appendix B, measurements collected at accessible and restricted areas were
found to be below 24.08% of the Occupational limits (120.2% of the General Population limits). Waterford
Consultants, LLC recommended contact information and RF Guidelines signage that informs personnel
entering the site of basic precautions to be followed when working around antennas is posted at the access
areas to the antennas. For areas on the roof near the antennas that are predicted to exceed the General
Population limits, indicative markers and RF alerting signs (Caution) have been posted that are 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.
