EXECUTIVE SUMMARY
Purpose of Report
Site No. SFSF001053A
12 Results Way, Cupertino, California
EnviroBusiness Inc. (dba EBI Consulting) has been contracted by Dish Wireless to conduct radio frequency
electromagnetic (RF-EME) modeling for Dish Wireless Site SFSF001053A located at 12 Results Way in
Cupertino, California to determine RF-EME exposure levels from proposed Dish Wireless
communications equipment at this site. As described in greater detail in Appendix C of this report, the
Federal Communications Commission (FCC) has developed Maximum Permissible Exposure (MPE) Limits
for the general public and for occupational activities. 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.
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 areas
on any accessible rooftop or ground -level walking/working surface related to the proposed antennas that
exceed the FCC's occupational or general public exposure limits at this site.
At the nearest walking/working surfaces to the Dish Wireless antennas, the maximum power density
generated by the DISH antennas is approximately 12.96 percent of the FCC's general public limit (2.59
percent of the FCC's occupational limit).
The composite exposure level from all carriers on this site is approximately 14.97 percent of the FCC's
general public limit (2.99 percent of the FCC's occupational limit) at the nearest walking/working surface
to each antenna.
Recommended control measures are outlined in Section 4.0 and within the Site Safety Plan (attached);
Dish Wireless should also provide procedures to shut down and lockout/tagout this wireless equipment
in accordance with their own standard operating protocol. Non -telecom workers who will be working in
areas of exceedance are required to contact Dish Wireless since only DISH has the ability to
lockout/tagout the facility, or to authorize others to do so.

1.0 INTRODUCTION
Site No. SFSF001053A
12 Results Way, Cupertino, California
Radio frequency waves are electromagnetic waves from the portion of the electromagnetic spectrum at
frequencies lower than visible light and microwaves. The wavelengths of radio waves range from thousands
of meters to around 30 centimeters. These wavelengths correspond to frequencies as low as 3 cycles per
second (or hertz [Hz]) to as high as one gigahertz (one billion cycles per second).
Personal Communication (PCS) facilities used by Dish Wireless in this area will potentially operate within
a frequency range of 600 to 5000 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 a distance 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 in areas in
the immediate vicinity of the antennas.
MPE limits do not represent levels where a health risk exists, since they 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.
2.0 SITE DESCRIPTION
This project site includes the following proposed wireless telecommunication antennas on a monotree
located at 12 Results Way in Cupertino, California.

The above tables contain an inventory of proposed Dish Wireless antennas and other carrier antennas if
sufficient information was available to model them. Note that EBI uses an assumed set of antenna
specifications and powers for unknown and other carrier antennas for modeling purposes. The FCC
guidelines incorporate two separate tiers of exposure limits that are based upon occupational/controlled
exposure limits (for workers) and general population/uncontrolled exposure limits for members of the
general public that may be exposed to antenna fields. While access to this site is considered controlled,
the analysis has considered exposures with respect to both controlled and uncontrolled limits as an
untrained worker may access adjacent rooftop locations. Additional information regarding
controlled/uncontrolled exposure limits is provided in Appendix C. Appendix B presents a site safety plan
that provides a plan view of the monotree with antenna locations.
3.0 WORST -CASE PREDICTIVE MODELING
EBI has performed theoretical MPE modeling using RoofMasterTM software to estimate the worst -case
power density at the site's nearby broadcast levels resulting from operation of the antennas. RoofMasterTM
is a widely -used predictive modeling program that has been developed by Waterford Consultants to
predict RF power density values for rooftop and tower telecommunications sites produced by vertical
collinear antennas that are typically used in the cellular, PCS, paging and other communications services.
Using the computational methods set forth in Federal Communications Commission (FCC) Office of
Engineering & Technology (OET) Bulletin 65, "Evaluating Compliance with FCC Guidelines for Human
Exposure to Radiofrequency Electromagnetic Fields" (OET-65), RoofMasterTM calculates predicted power
density in a scalable grid based on the contributions of all RF sources characterized in the study scenario.
At each grid location, the cumulative power density is expressed as a percentage of the FCC limits.

Manufacturer antenna pattern data is utilized in these calculations. RoofMasterT"^ models consist of the
Far Field model as specified in OET-65 and an implementation of the OET-65 Cylindrical Model (Sula9).
The models utilize several operational 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 Dish Wireless 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 Dish Wireless
and information gathered from other sources. Elevations of walking/working surfaces were estimated
based on elevations provided and available aerial imagery. Sector orientation assignments were made
assuming coverage is directed to areas of site. Changes to antenna mount heights or placement will impact
site compliance. The parameters used for modeling are summarized in the Site Description antenna
inventory table in Section 2.0.
AT&T also has antennas on the monotree. Information about these antennas was included in the modeling
analysis.
Based on worst -case predictive modeling, there are no modeled areas on any accessible rooftop or
ground -level walking/working surface related to the proposed Dish Wireless antennas that exceed the
FCC's occupational or general public exposure limits at this site. At the nearest walking/working surfaces
to the Dish Wireless antennas, the maximum power density generated by the Dish Wireless antennas is
approximately 12.96 percent of the FCC's general public limit (2.59 percent of the FCC's occupational
limit). The composite exposure level from all carriers on this site is approximately 14.97 percent of the
FCC's general public limit (2.99 percent of the FCC's occupational limit) at the nearest walking/working
surface to each antenna.
The Site Safety Plan also presents areas where Dish Wireless antennas contribute greater than 5% of the
applicable MPE limit for a site. 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.
There are no modeled areas on the rooftop and ground that exceed the FCC's limits for general public
or occupational exposure in front of the other carrier antennas.
The inputs used in the modeling are summarized in the Site Description antenna inventory table in Section
2.0. A graphical representation of the RoofMasterTM modeling results is presented in Appendix B.
Microwave dish antennas are designed for point-to-point operations at the elevations of the installed
equipment rather than ground level coverage. The maximum power density generated by all carrier
antennas, including microwaves and panel antennas, is included in the modeling results presented within
this report.
4.0 MITIGATION/SITE CONTROL OPTIONS
EBI's modeling indicates that there are no areas in front of the Dish Wireless antennas that exceed the
FCC standards for occupational or general public exposure. All exposures above the FCC's safe limits
require that individuals be elevated above the ground. In order to alert people accessing the monotree, a
Warning sign and an NOC Information sign are recommended for installation 10 feet above ground level
at the base of the monotree.
Barriers are recommended for installation when possible to block access to the areas in front of the
antennas that exceed the FCC general public and/or occupational limits. Barriers may consist of rope,

chain, or fencing. Painted stripes should only be used as a last resort. There are no barriers recommended
on this site.
These protocols and recommended control measures have been summarized and included with a graphic
representation of the antennas and associated signage and control areas in a RF-EME Site Safety Plan,
which is included as Appendix B. Individuals and workers accessing the monotree should be provided with
a copy of the attached Site Safety Plan, made aware of the posted signage, and signify their understanding
of the Site Safety Plan.
To reduce the risk of exposure, EBI recommends that access to areas associated with the active antenna
installation be restricted and secured where possible.
Implementation of the signage recommended in the Site Safety Plan and in this report will bring this site
into compliance with the FCC's rules and regulations.
5.0 SUMMARY AND CONCLUSIONS
EBI has prepared a Radiofrequency — Electromagnetic Energy (RF-EME) Compliance Report for
telecommunications equipment installed by Dish Wireless Site Number SFSFOO1053A located at 12
Results Way in Cupertino, California to determine worst -case predicted RF-EME exposure levels from
wireless communications equipment installed at this site. This report summarizes the results of RF-EME
modeling in relation to relevant Federal Communications Commission (FCC) RF-EME compliance
standards for limiting human exposure to RF-EME fields.
As presented in the sections above, based on the FCC criteria, there are no modeled areas on any
accessible rooftop or ground -level walking/working surface related to the proposed antennas that exceed
the FCC's occupational or general public exposure limits at this site.
Workers should be informed about the presence and locations of antennas and their associated fields.
Recommended control measures are outlined in Section 4.0 and within the Site Safety Plan (attached);
Dish Wireless should also provide procedures to shut down and lockout/tagout this wireless equipment
in accordance with their own standard operating protocol. Non -telecom workers who will be working in
areas of exceedance are required to contact Dish Wireless since only Dish Wireless has the ability to
lockout/tagout the facility, or to authorize others to do so.

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 I and Figure I (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 I mW/cm2 for equipment operating in the 1900 MHz frequency
range. For the Dish Wireless equipment operating at 600 MHz or 850 MHz, the FCC's occupational MPE
is 2.83 mW/cm2 and an uncontrolled MPE of 0.57 mW/cm2. For the Dish Wireless equipment operating
at 1900 MHz, the FCC's occupational MPE is 5.0 mW/cm2 and an uncontrolled MPE limit of 1.0 mW/cm2.
These limits are considered protective of these populations.

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 Dish Wireless in this area will potentially operate within
a frequency range of 600 to 2100 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.
FCC Compliance Requirement
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.
