Compliance Statement
Based on information provided by Verizon Wireless and predictive modeling, the West Cupertino installation
proposed by Verizon Wireless will be compliant with Radiofrequency Radiation Exposure Limits of 47 C.F.R.
§§ 1.1307(b)(3) and 1.1310. The proposed operation will not expose members of the General Public to
hazardous levels of RF energy at ground level or in adjacent buildings. As predicted RF power densities will
not exceed the FCC General Population limits, no mitigation action other than restricting access to the tower
is required to achieve or maintain compliance.
Certification
I, David C. Cotton, Jr., 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 FCCβs 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
(βMPEβ) 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:
ππ= πΈπΈπΈπΈπΈπΈπΈπΈ4β ππβ πΈπΈ2 (mW/cm2)
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 manufacturersβ 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
ππ=οΏ½180πππ΅π΅π΅π΅οΏ½β 100 β ππππππππβ π π β β (mW/cm2)
where Pin is the power input to the antenna, ΞΈBW 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 maximum-case predictions as all RF
emitters are assumed to be operating at 100% duty cycle.

Analysis
Verizon Wireless proposes the following installation at this location:
β’ REMOVE: 6 (E) PANEL ANTENNAS -2 PER SECTOR
β’ REMOVE: 3 (E) RRUS-12 B4-1 PER SECTOR
β’ INSTALL: 9 (P0 PANEL ANTENNA-3 PER SECTOR
β’ INSTALL: 3 (P) RRUS-8843 B66A/B2-1 PER SECTOR
The antennas will be mounted on a 70-foot monopine with centerlines 62 feet above ground level. Proposed
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.

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 25.9385% 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 55.928% 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. As predicted
RF power densities will not exceed the FCC General Population limits, no mitigation action other than restricting
access to the tower is required to achieve or maintain compliance.
