1.0 EXECUTIVE SUMMARY
Dtech Communications, LLC (“Dtech”) has been retained by Verizon, care of Sequoia, to determine whether its
wireless communications facility complies with the Federal Communications Commission (FCC) Radio Frequency
(RF) Safety Guidelines. This report contains a PRE-activation, computer-simulated analysis of the Electromagnetic
Energy (EME) exposure resulting from the facility. The cumulative analysis includes contributions from existing
wireless carriers on site, where applicable and information is provided. Results are compared to FCC’s General
Population (GP) Maximum Permissible Exposure (MPE) Limits. The tables below summarizes the results of our
EME assessment at a glance:

4.0 CONCLUSION
4.1 Results
For a typical 6-foot person standing in accessible areas on the Ground and Adjacent Bldg Roof, exposure levels for
Verizon's site are calculated to be BELOW the FCC's most stringent General Population MPE Limits.
At antenna elevation, the highest calculated exposure level is above the FCC’s General Population MPE Limits near
the Verizon antenna(s). The maximum overexposed areas extend 90-feet from the front face of the Verizon
antenna(s). There are no other buildings or surrounding structures at or higher than antenna height within the
overexposed areas. Beyond this clearance distance, exposure levels are predicted to be below the FCC’s General
Population MPE Limits.
The antennas are mounted on a tall tower and therefore not accessible by the general public. It is presumed that
Verizon employees and contractors are aware of the transmitting antennas and will take appropriate precautions
when working near them.
4.2 Recommendation(s)
Further actions are not required.
4.3 Statement of Compliance
Based on the results, analysis and recommendation(s), it is the undersigned’s professional opinion that Verizon's site
is compliant with the FCC's RF Safety Guidelines.
4.4 Engineer Certification
This report has been prepared by or under the direction of the following Registered Professional Engineer: Darang
Tech, holding California registration number 16000. I have reviewed this report and believe it to be both true and
accurate to the best of my knowledge.

Appendix A: Background
Dtech uses the FCC’s guidelines described in detail in Office of Engineering & Technology, Bulletin No. 65
(“OET-65”) “Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency
Electromagnetic Fields”. The table below summarizes the current Maximum Permissible Exposure (“MPE”) safety
limits classified into two groups: General population (GP) and Occupational (OC).

General population/uncontrolled limits apply in situations in which the general public may be exposed or in
which persons who are exposed as a consequence of their employment, and may not be fully aware of the potential
for exposure or cannot exercise control over their exposure. Therefore, members of the general public always fall
under this category when exposure is not employment-related.
Occupational/controlled limits apply in situations in which persons are exposed as a consequence of their
employment, and those persons have been made fully aware of the potential for exposure and can exercise control
over their exposure. Occupational/controlled limits also apply where exposure is of a transient nature as a result of
incidental passage through a location where exposure levels may be above general population/uncontrolled limits,
as long as the exposed person has been made fully aware of the potential for exposure and can exercise control over
his or her exposure by leaving the area or by some other appropriate means.
It is important to understand that the FCC guidelines specify exposure limits not emission limits. For a transmitting
facility to be out of compliance with the FCC's RF safety guidelines an area or areas where levels exceed the MPE
limits must, first of all, be in some way accessible to the public or to workers. When accessibility to an area where
excessive levels is appropriately restricted, the facility or operation can certify that it complies with the FCC
requirements.
In general, when the guidelines specified in § 1.1310 are exceeded in an accessible area due to the emissions from
multiple fixed transmitters, actions necessary to bring the area into compliance are the shared responsibility of all
licensees whose transmitters produce, at the area in question, power density levels that exceed 5% of the power
density exposure limit applicable to their particular transmitter or field strength levels that, when squared, exceed
5% of the square of the electric or magnetic field strength limit applicable to their particular transmitter.
The FCC classifies four categories, 1 through 4, reflecting potential RF exposure scenarios along with required
signage:
● Category 1 - levels at or below the MPE limits (100%) - GREEN Information sign is optional.
● Category 2 - levels between 1x up to 5x GP MPE limits (100%-500%) - BLUE Notice sign required.
● Category 3 - levels between 5x up to 50x GP MPE limits (500%-5,000%) - YELLOW Caution sign required.
● Category 4 - levels greater than 50x GP MPE limits (>5,000%) - ORANGE or RED Warning sign required.

Appendix B: Measurement and/or Computer Simulation Methods
Spatial averaging measurement technique is used. An area between 2 and 6 feet, approximately the size of an
average human, is scanned in single passes from top to bottom in multiple planes. When possible, measurements
were made at very close proximity to the antennas and inside the main beam where most of the energy is emitted.
The spatial averaged values were recorded. A result higher than 100% exceeds the FCC’s General Population MPE
Limits.
Dtech uses an industry standard power density prediction computer Model2 to assess the worse-case, cumulative
EMF impact of the surrounding areas of the subject site. In addition, the analysis is performed at 80% duty cycle
for all (C-Band/CBRS/mmWave/AAH) TDD technologies. All other frequencies are operating at 100% duty cycle
transmitting at maximum total power. Lower Interiors (if applicable), were analyzed 10-feet below roof level with a
10dB deck attenuation. For purposes of a cumulative study, nearby transmitters are included where possible. The
result is a surrounding area map color-coded to percentages of the applicable FCC’s MPE Limits.
Appendix C: Plot Legend
Plot color legends adhere to the FCC’s category classification: WHITE represents areas where exposure levels are
predicted to be at or below 5%; GREEN (Category 1) between 5% & up to 100%, which is below the MPE limits;
BLUE, YELLOW & RED (Categories 2, 3 and 4 respectively) above 100%, which exceeds the MPE limits.
Individuals can safely occupy areas in WHITE and GREEN for indefinite amount of time; whereas areas in BLUE,
YELLOW & RED must be restricted to RF trained personnel who has been made fully aware of potential for
exposure, has control and knows how to reduce their exposure with the use of personal protection equipment or
has the ability to power down the transmitters.
