EXECUTIVE SUMMARY
Purpose of Report
EnviroBusiness Inc. (dba EBI Consulting) has been contracted by AT&T Mobility, LLC to conduct radio
frequency electromagnetic (RF-EME) modeling for AT&T Site CVL03312 located at Lower Forbestown
Road in Forbestown, California to determine RF-EME exposure levels from proposed AT&T wireless
communications equipment at this site. As described in greater detail in Section 2.0 of this report, the
Federal Communications Commission (FCC) has developed Maximum Permissible Exposure (MPE)
Limits for general public exposures and occupational exposures. This report summarizes the results of
RF-EME modeling in relation to relevant FCC RF-EME compliance standards for limiting human
exposure to RF-EME fields.
This report contains a detailed summary of the RF EME analysis for the site, including the following:
Antenna Inventory
Site Plan with antenna locations
Antenna inventory with relevant parameters for theoretical modeling
Graphical representation of theoretical MPE fields based on modeling
Graphical representation of recommended signage and/or barriers
This document addresses the compliance of AT&T’s transmitting facilities independently and in relation
to all collocated facilities at the site.
Statement of Compliance
A site is considered out of compliance with FCC regulations if there are areas that exceed the FCC
exposure limits and there are no RF hazard mitigation measures in place. Any carrier which has an
installation that contributes more than 5% of the applicable MPE must participate in mitigating these RF
hazards.
As presented in the sections below, based on worst-case predictive modeling, there are no modeled
exposures on any accessible ground walking/working surface related to ATT’s proposed antennas that
exceed the FCC’s occupational and/or general public exposure limits at this site.
AT&T Recommended Signage/Compliance Plan
AT&T’s RF Exposure: Responsibilities, Procedures & Guidelines document, dated October 28, 2014,
requires that:
1. All sites must be analyzed for RF exposure compliance;
2. All sites must have that analysis documented; and
3. All sites must have any necessary signage and barriers installed.
Site compliance recommendations have been developed based upon protocols presented in AT&T’s RF
Exposure: Responsibilities, Procedures & Guidelines document, dated October 28, 2014, additional
guidance provided by AT&T, EBI’s understanding of FCC and OSHA requirements, and common
industry practice. Barrier locations have been identified (when required) based on guidance presented in
AT&T’s RF Exposure: Responsibilities, Procedures & Guidelines document, dated October 28, 2014.

1.0 SITE DESCRIPTION
This project involves the proposed installation of up to twelve (12) wireless telecommunication
antennas on a lattice tower in Forbestown, California. There are three Sectors (A, B, and C) proposed
at the site, with four (4) proposed antennas per sector. For modeling purposes, it is assumed that there
will be four (4) LTE antennas in each sector transmitting in the 700, 850, 1900, 2100, and 2300 MHz
frequency ranges. The Sector A antennas will be oriented 60° from true north. The Sector B antennas
will be oriented 300° from true north. The Sector C antennas will be oriented 180° from true north.
The bottoms of the antennas will be approximately 143 feet above ground level. Appendix B presents an
antenna inventory for the site.
Access to this site is accomplished via a gate in the fence surrounding the lattice tower. Workers must
be elevated to antenna level to access them, so these antennas are not accessible to the general public.
Modeling results were generated based on information from the following materials:
RFDS – CVL03312 RFDS v1.00.02 – 05-10-17 dated 5/10/2017
CDs – CVL03312 100 ZD – DRM Approval – 05-15-17 dated 5/15/2017
2.0 FEDERAL COMMUNICATIONS COMMISSION (FCC) REQUIREMENTS
The FCC has established Maximum Permissible Exposure (MPE) limits for human exposure to
Radiofrequency Electromagnetic (RF-EME) energy fields, based on exposure limits recommended by the
National Council on Radiation Protection and Measurements (NCRP) and, over a wide range of
frequencies, the exposure limits developed by the Institute of Electrical and Electronics Engineers, Inc.
(IEEE) and adopted by the American National Standards Institute (ANSI) to replace the 1982 ANSI
guidelines. Limits for localized absorption are based on recommendations of both ANSI/IEEE and NCRP.
The FCC guidelines incorporate two separate tiers of exposure limits that are based upon
occupational/controlled exposure limits (for workers) and general public/uncontrolled exposure limits
for members of the general public.
Occupational/controlled exposure limits apply to situations in which persons are exposed as a
consequence of their employment and in which those persons who are exposed have been made fully
aware of the potential for exposure and can exercise control over their exposure. Occupational/
controlled exposure 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 public/uncontrolled limits (see
below), 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.
General public/uncontrolled exposure limits apply to situations in which the general public may be
exposed or in which persons who are exposed as a consequence of their employment may not be made
fully aware of the potential for exposure or cannot exercise control over their exposure. Therefore,
members of the general public would always be considered under this category when exposure is not
employment-related, for example, in the case of a telecommunications tower that exposes persons in a
nearby residential area.
Table 1 and Figure 1 (below), which are included within the FCC’s OET Bulletin 65, summarize the MPE
limits for RF emissions. These limits are designed to provide a substantial margin of safety. They vary by
frequency to take into account the different types of equipment that may be in operation at a particular

facility and are “time-averaged” limits to reflect different durations resulting from controlled and
uncontrolled exposures.
The FCC’s MPEs are measured in terms of power (mW) over a unit surface area (cm2). Known as the
power density, the FCC has established an occupational MPE of 5 milliwatts per square centimeter
(mW/cm2) and an uncontrolled MPE of 1 mW/cm2 for equipment operating in the 1900 MHz frequency
range. For the AT&T equipment operating at 850 MHz, the FCC’s occupational MPE is 2.83 mW/cm2
and an uncontrolled MPE of 0.57 mW/cm2. For the AT&T equipment operating at 700 MHz, the FCC’s
occupational MPE is 2.33 mW/cm2 and an uncontrolled MPE of 0.47 mW/cm2. These limits are
considered protective of these populations.

EBI Consulting 21 B Street Burlington, MA 01803 1.800.786.2346
Based on the above, the most restrictive thresholds for exposures of unlimited duration to RF energy
for several personal wireless services are summarized below:
Personal Wireless Service Approximate
Frequency
Occupational
MPE Public MPE
Personal Communication (PCS) 1,950 MHz 5.00 mW/cm2 1.00 mW/cm2
Cellular Telephone 870 MHz 2.90 mW/cm2 0.58 mW/cm2
Specialized Mobile Radio 855 MHz 2.85 mW/cm2 0.57 mW/cm2
Long Term Evolution (LTE) 700 MHz 2.33 mW/cm2 0.47 mW/cm2
Most Restrictive Freq, Range 30-300 MHz 1.00 mW/cm2 0.20 mW/cm2
MPE limits are designed to provide a substantial margin of safety. These limits apply for continuous
exposures and are intended to provide a prudent margin of safety for all persons, regardless of age,
gender, size, or health.
Personal Communication (PCS) facilities used by AT&T in this area operate within a frequency range of
700-1900 MHz. Facilities typically consist of: 1) electronic transceivers (the radios or cabinets)
connected to wired telephone lines; and 2) antennas that send the wireless signals created by the
transceivers to be received by individual subscriber units (PCS telephones). Transceivers are typically
connected to antennas by coaxial cables.
Because of the short wavelength of PCS services, the antennas require line-of-site paths for good
propagation, and are typically installed above ground level. Antennas are constructed to concentrate
energy towards the horizon, with as little energy as possible scattered towards the ground or the sky.
This design, combined with the low power of PCS facilities, generally results in no possibility for
exposure to approach Maximum Permissible Exposure (MPE) levels, with the exception of areas directly
in front of the antennas.
3.0 AT&T RF EXPOSURE POLICY REQUIREMENTS
AT&T’s RF Exposure: Responsibilities, Procedures & Guidelines document, dated October 28, 2014,
requires that:
1. All sites must be analyzed for RF exposure compliance;
2. All sites must have that analysis documented; and
3. All sites must have any necessary signage and barriers installed.
Pursuant to this guidance, worst-case predictive modeling was performed for the site. This modeling is
described below in Section 4.0. Lastly, based on the modeling and survey data, EBI has produced a
Compliance Plan for this site that outlines the recommended signage and barriers. The recommended
Compliance Plan for this site is described in Section 5.0.
4.0 WORST-CASE PREDICTIVE MODELING
In accordance with AT&T’s RF Exposure policy, EBI performed theoretical modeling using RoofView®
software to estimate the worst-case power density at the site ground-level resulting from operation of
the antennas. RoofView® is a widely-used predictive modeling program that has been developed by
Richard Tell Associates to predict both near field and far field RF power density values for roof-top and
tower telecommunications sites produced by vertical collinear antennas that are typically used in the
cellular, PCS, paging and other communications services. The models utilize several operational
RF-EME Compliance Report USID No. 174087 Site No. CVL03312
EBI Project No. 6217002157 Lower Forbestown Road, Forbestown, California
EBI Consulting 21 B Street Burlington, MA 01803 1.800.786.2346
specifications for different types of antennas to produce a plot of spatially-averaged power densities that
can be expressed as a percentage of the applicable exposure limit.
For this report, EBI utilized antenna and power data provided by AT&T and compared the resultant
worst-case MPE levels to the FCC’s occupational/controlled exposure limits outlined in OET Bulletin 65.
The assumptions used in the modeling are based upon information provided by AT&T and information
gathered from other sources. There are no other wireless carriers with equipment installed at this site.
Based on worst-case predictive modeling, there are no modeled exposures on any accessible ground
walking/working surface related to ATT’s proposed antennas that exceed the FCC’s occupational and/or
general public exposure limits at this site.
At the nearest walking/working surfaces to the AT&T antennas, the maximum power density generated
by the AT&T antennas is approximately 2.70 percent of the FCC’s general public limit (0.54 percent of
the FCC’s occupational limit). The composite exposure level from all carriers on this site is
approximately 2.70 percent of the FCC’s general public limit (0.54 percent of the FCC’s occupational
limit) at the nearest walking/working surface to each antenna.
The inputs used in the modeling are summarized in the RoofView® export file presented in Appendix C.
A graphical representation of the RoofView® modeling results is presented in Appendix D. It should be
noted that RoofView® is not suitable for modeling microwave dish antennas; however, these units are
designed for point-to-point operations at the elevations of the installed equipment rather than ground-
level coverage. Based on AT&T’s RF Exposure: Responsibilities, Procedures & Guidelines document,
dated October 28, 2014, microwave antennas are considered compliant if they are higher than 20 feet
above any accessible walking/working surface. All microwaves on site are considered compliant with
AT&T’s guidance and were not included in the modeling analysis.

5.0 RECOMMENDED SIGNAGE/COMPLIANCE PLAN
Signs are the primary means for control of access to areas where RF exposure levels may potentially
exceed the MPE. As presented in the AT&T guidance document, the signs must:
Be posted at a conspicuous point;
Be posted at the appropriate locations;
Be readily visible; and
Make the reader aware of the potential risks prior to entering the affected area.
The table below presents the signs that may be used for AT&T installations.

1. Note there are only 4 AT&T antennas per sector at this site. For clarity, the different frequencies for each antenna are entered on separate lines.
2. Note that the microwaves were not included in the predictive modeling analysis because microwaves onsite are considered compliant. RoofView is not
suitable for modeling microwave dish antennas because these units are designed for point-to-point operations at the elevations of the installed equipment
rather than ground-level coverage.
