1 Executive Summary
EAS Inc. has been hired by T-Mobile West, LLC to analyze RF-EME Exposure and Site Compliance for a
site with following information:
Number of Sectors 3
Total Number of T-Mobile Antennas 9
Overall Structure Heiizht 42.8 I Feet
Topline heiizht ofT-Mobile Antennas 37.5 I Feet
Nearby buildings at antenna height? □Yes ~No
The Antenna Inventory Table (Section 2) shows all transmitting antennas on the site. The use of"Unknown"
for an operator means the information with regard to the carrier, their FCC license and I or antenna
information was not available. Generic values used as estimation for Effective Radiated Power (ERP) and
antenna characteristics for unknown antennas. Z reference specifies the bottom of the antenna to the
indicated level.
In this report, it is assumed that all antennas are operating at full power at all times. Software modeling was
performed for all transmitting antennas located on the site. EAS has further assumed a 100% duty cycle
and maximum radiated power. Obstructions (trees, buildings etc.) that would normally attenuate the signal
are not taken into account. As a result, the predicted signal levels are more conservative (higher) than the
actual signal levels will be from the measurement conclusions. The modeling software that EAS used to
create this report is Roofview 4.15.
Statement of Compliance (Section 4) indicated detailed actions required to bring the site compliant to FCC
and OSHA rules and regulations with regard to Human Exposure to Radio Frequency Radiation by use of
T-Mobile RF signage, barriers and Demarcation Policy. The whole report is true and accurate to the best of
Report Creator and Report Reviewer's (mentioned in first page) knowledge.
Additional information about how the report is created and modeled is located in Appendix A and Appendix
ft of this report.

5 AppendixA
5.1 FCC Rules and Regulations
This appendix summarizes the policies, guidelines and requirements that were adopted by the FCC on
August 1, 1996, amending Part 1 of Title 47 of the Code of Federal Regulations, and further amended by
action of the Commission on August 25, 1997 (see 47 CFR Sections l.1307(b), 1.1310, 2.1091 and 2.1093,
as amended from FCC "OET Bulletin 65"). Commission actions granting construction permits, licenses to
transmit or renewals thereof, equipment authorizations or modifications in existing facilities, require the
preparation of an Environmental Assessment (EA), as described in 47 CFR Section 1.1311, if the particular
facility, operation or transmitter would cause human exposure to levels of radiofrequency (RF)
electromagnetic fields in excess of these limits. For exact language, see the relevant FCC rule sections.
The FCC-adopted limits for Maximum Permissible Exposure (MPE) are generally based on
recommended exposure guidelines published by the National Council on Radiation Protection and
Measurements (NCRP) in "Biological Effects and Exposure Criteria for Radiofrequency Electromagnetic
Fields," NCRP Report No. 86, Sections 17.4.l, 17.4.1.1, 17.4.2 and 17.4.3. Copyright NCRP, 1986,
Bethesda, Maryland 20814. In the frequency range from 100 MHz to 1500 MHz., exposure limits for field
strength and power density are also generally based on the MPE limits found in Section 4.1 of, "IEEE
Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields,
3 kHz to 300 GHz," ANSI/IEEE C95. l-l 992, Copyright 1992 by the Institute of Electrical and Electronics
Engineers, Inc., New York, New York 10017, and approved for use as an American National Standard by
the American National Standards Institute (ANSI). The exposure guidelines are based on thresholds for
known adverse effects and they incorporate appropriate margin of safety. The federal health and safety
agencies such as: the Environmental Protection Agency (''EPA''), the Food and Drug Administration
("FDA"), the National Institute on Occupational Safety and Health (''NIOSH") and the Occupational Safety
and Health Administration ("OSHA") have also been actively involved in monitoring and investigating
issues related to RF exposure.
The formulas used in Roofview 4.15 for calculating Power density is based on FCC "OET Bulletin 65",
Section 2: PREDICTION METHODS, August 1997, Edition 97-01. Power density is converted to
Maximum Permissible Exposure Limits (MPE Limits) based on Limits of General population/Uncontrolled
Exposure and Limits of Occupational/Controlled Exposure presented in the following table generated from

5.2 Safety Recommendations
5.2.1 Occupational Safety and Health Administration (OSHA) Requirements
OSHA requires that those in the Occupational classification must complete training in RF Safety, RF
Awareness, and Utilization of Personal Protective Equipment. OSHA also provides options for Hazard
Prevention and Control:
Hazard Prevention Control
• Utilization of good equipment • Employ Lockout/Tag out
• Enact control of hazard areas • Utilize personal alarms & protective clothing
• Limit exposures • Prevent access to hazardous locations
• Employ medical surveillance and accident • Develop or operate an administrative control
response program
5.2.2 RF Signage and Barriers
RF signs and preventive barriers have an important role in appropriately alerting a worker before entering
into a potential RF exposure area. AU RF signs should be abided by at all times.

&CAUTION
Considering the antennas behind the screen are transmitting in the upper UHF (300 -3000 MHz) and
Microwave (SHF) (3000+ MHz) ranges, a Lock-Out/fag-Out Plan for energy sources should be included
in the Work Plans for both the scaffolding erection/dismantling contractor and the building contractor who
will be removing/replacing the screens.

6.1 Contribution to Co-Located areas
Any wireless operator that contributes 5% or greater of the MPE limit in an area that is identified to be
greater than 100% of the MPE limit is responsible taking corrective actions to bring the site into compliance.
All co-located sites should have a separate 5% modeling that shows only T-Mobile antennas transmitting.
This separate modeling indicates T-Mobile's contribution in all areas that is recognized to be greater %100
MPE limits.
6.2 Occupational limits
Apply in situations in which persons are exposed as a consequence of their employment provided those
persons are fully aware of the potential for exposure and can exercise control over their exposure. Limits
for occupational/controlled exposure also apply in situations when an individual is transient through a
location where occupational/controlled limits apply provided he or she is made aware of the potential for
exposure.
6.3 General population limits
Apply in situations in which the general public may be exposed, or in which persons that are exposed as
a consequence of their employment may not be fully aware of the potential for exposure or cannot exercise
control over their exposure. (Those without significant and documented RF Safety & Awareness training)
6.4 Controlled Environment
Applies to environments that are restricted or "controlled" in order to prevent access from members of
the General Population classification.
6.5 Uncontrolled Environment
Applies to environments that are unrestricted or ''uncontrolled" that allow access from members of the
General Population classification.
6.6 Generic Values
The use of"Unknown" for an operator means the information with regard to the carrier, their FCC license
and / or antenna information was not available. Generic values used as estimation for Effective Radiated
Power (ERP) and antenna characteristics for unknown antennas.
