T-Mobile Antenna Site

PROJECT NARRATIVE: T-MOBILE ANTENNA SITE MODIFICATION

Site: #286 Water Tower at the Henry A. Wallace Beltsville Agricultural Research Center (BARC) located in Beltsville, Maryland. The BARC property covers over 6,500 acres. Other Federal facilities located adjacent to BARC property include the Patuxent Wildlife Research Center, the Goddard Space Flight Center, and the U.S. Secret Service James T. Rowley Training Center. The cities of College Park and Greenbelt are located south of BARC property. Background: This project is being undertaken by T-Mobile in an effort to update their sites within the Washington/Baltimore market. Proposal: T-Mobile proposes to replace three of nine existing panel antennas with new panel antennas in the same locations on the #286 Water Tower. They also propose to add three lines of hybrid cabling within their existing coaxial run. The dimensions of the existing AIR 21 antennas are 1422 x 307 x 200 (56” x 12” x 8”). The dimensions of the new AIR 32 antennas are 1439 x 327 x 220 (56.6” x 12.9” x 8.7”). The antennas will be painted to blend with the color of the Water Tower to minimize visibility. The Radio Frequency (RF) Site Compliance Report prepared by EBI Consulting indicates the antenna site would be in compliance with RF safety requirements. National Environmental Policy Act (NEPA): In accordance with the National Environmental Policy Act, BARC has determined that the modifications proposed by T-Mobile are a categorical exclusion under ARS regulations 7 CFR 520.5 (b) (1). National Historic Preservation Act (NHPA): On January 5, 2018, the Maryland Historical Trust concurred with the no adverse effect finding regarding this undertaking.

RF‐EME Theoretical MPE Summary Introduction

EBI Consulting was directed to analyze the proposed T-Mobile water tank facility (7WAS039C) located at Edmonston Road in Greenbelt, Maryland for the purpose of determining whether the emissions from the proposed T-Mobile Antenna Installation located on this property are within specified federal limits.

MPE Calculations

Calculations were done for the proposed T-Mobile Wireless antenna water tank facility located at Edmonston Road in Greenbelt, Maryland using worst-case analysist to predict possible areas of exceedance of FCC RF emissions levels.

The anticipated maximum composite MPE value for this site is 1.7% of the allowable FCC established general public limit (0.34% of the FCC occupational limit). This is based upon worst case modeling performed on the ground.

Signage

Signs are the primary means for control of access to areas where RF exposure levels may exceed the MPE limits. In order to meet FCC requirements, 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.

1.0 Executive Summary

EnviroBusiness Inc. (dba EBI Consulting) has been contracted by T-Mobile to conduct radio frequency

electromagnetic (RF-EME) monitoring and modeling for T-Mobile Site 7WAS039C located at Edmonston

Road in Greenbelt, Maryland to determine RF-EME exposure levels from proposed T-Mobile wireless

communications equipment at this site. As described in detail in Appendix B 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

monitoring and modeling in relation to relevant FCC RF-EME compliance standards for limiting human

exposure to RF-EME fields. EBI field personnel visited this site on June 04, 2018. This report contains a

detailed summary of the RF EME analysis for the site.

This document addresses the compliance of T-Mobile’s proposed transmitting facilities independently

and in relation to all existing collocated facilities at the site.

The Maximum Composite Emissions Value is 2.7000% of the FCC’s general public limit (0.5400% of the

FCC’s occupational limit) at the ground. The proposed site is in compliance with Federal regulations

regarding (radio frequency) RF Emissions.

Based on worst-case predictive modeling, there are no modeled exposures on any accessible ground-

level walking/working surface related to T-Mobile’s equipment in the area that exceed the FCC’s

occupational and/or general public exposure limits at this site. There are no modeled areas on the

ground that exceed the FCC’s limits for general public or occupational exposure in front of the other

carrier antennas.

Signage is not required at the site as presented in Attachment 1. The site is compliant with FCC rules

and regulations.


2.0 MPE Calculations

Calculations were completed for the proposed T-Mobile Wireless antenna water tank facility located at

Edmonston Road in Greenbelt, Maryland using the equipment information listed below. All calculations

were performed per the specifications under FCC OET 65. 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.

In accordance with T-Mobile’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.

For this report, EBI utilized antenna and power data provided by T-Mobile and compared the resultant

worst-case MPE levels to the FCC’s occupational/controlled exposure limits outlined in OET Bulletin 65.

EBI has performed theoretical worst case modeling using RoofView® to estimate the maximum

potential power density from each proposed antenna based on worst-case assumptions for the number

of antennas and power. All radios at the proposed installation were considered to be running at full

power and were uncombined in their RF transmission paths per carrier prescribed configuration. In

addition, Sprint proposes the installation of XXX (#) microwave dishes at the site.

The assumptions used in the modeling are based upon information collected during the site survey andinformation provided by T-Mobile in the supplied drawings and known configuration values information gathered from other sources to approximate each additional carrier’s contribution.

The Maximum Emissions Value for the additional carriers included in the modeling is 1.80% of the FCC

general public limit (0.36% of the FCC occupational limit) at the ground walking/working surfaces.

The data for all T-Mobile antennas used in this analysis is shown in Section 4.0. Actual antenna gains for each antenna were used per manufacturer’s specifications. All calculations were done with respect to uncontrolled and general public threshold limits.


3.0 Site and Vicinity Survey

EBI performed a ground level RF-EME survey on June 4, 2018. The antenna inventory (based upon the

site survey) and site photos taken from ground level are presented in Appendices A and B, respectively.

Monitoring was performed using a Narda NBM-550 Electromagnetic Radiation Survey Meter, Serial #E-

0451 with a Narda EA5091-shaped probe with a frequency range of 300kHz-50 GHz. The meter was

last calibrated on August 18, 2017. This meter was programmed to measure the total power density for

all electromagnetic radiation within the 300kHz-50GHz frequency range and report the power density

as a percent of the FCC’s controlled MPE. During this survey, no spatially averaged readings above

0.0761% of the FCC’s occupational MPE (0.3805% of the general public MPE) were encountered on any

ground surface. This maximum spatially averaged reading was measured at ground level outside of the

compound gate to the east, as shown in the monitoring site plan in Appendix E. A site plan depicting

monitoring locations and measurements of power density can be found in Appendix E. Appendix F

contains notes from the site survey.

Access to this site is accomplished by approaching the unsecured water tank at ground level. To be

conservative and to comply with T-Mobile’s corporate policy, the modeling results are reported as

though the general public is able to access the water tank.

At the time of the site survey, it was noted that there was a yellow “Guidelines” sign and a blue

“Notice” sign on the access gate indicating the presence of RF emitting equipment at the site.

This analysis report contains both theoretical modeling calculations as well as actual onsite Power

Density measurements. The theoretical modeling calculations will typically show a worst case scenario

as it is typically modeled after the largest channel grouping and power level possible at the site. Onsite

Monitoring will give a snapshot of the composite RF field levels at the time the survey was completed.

Due to this, there is a possibility that large differences may be seen between the modeled RF conditions

and those observed in the field. Additionally, this becomes a multiplier effect if multiple carriers are

modeled at maximum powers.

5.0 Summary and Conclusions

All calculations performed for this analysis yielded results that were within the allowable limits for exposure to RF Emissions. Based on predictive modeling, there are no modeled exposures on any accessible ground-level walking/working surface related to T-Mobile’s equipment in the area that exceed the FCC’s occupational and/or general public exposure limits at this site. There are no modeled areas on the ground that exceed the FCC’s limits for general public or occupational exposure in front of the other carrier antennas. Installation of mitigation measures will bring the proposed site into compliance. The anticipated maximum contribution from each sector of the proposed T-Mobile facility is 1.2% of the

allowable FCC established general public limit (0.24% of the FCC occupational limit). This was

determined through calculations along a radial from each sector taking full power values into account as

well as actual vertical plane antenna gain values per the manufacturers supplied specifications for gain.

The anticipated maximum composite MPE value for this site is 2.7% of the allowable FCC established

general public limit (0.54% of the FCC occupational limit). This is based upon worst-case modeling

performed on the ground taking emissions contributions from all carriers present into account. This

value will determine whether the proposed site will be in compliance with regards to electromagnetic

emissions. Microwave dish antennas are designed for point-to-point operations at the elevations of the

installed equipment rather than ground level coverage. RoofView® is not suitable for modeling them.

However, formulas for OET Bulletin 65 were used to calculate a worst-case prediction of the maximum

power density (MPE) at ground level and nearest walking surfaces for the Sprint microwave dishes.

Power density estimates used for the microwave dishes proposed for installation at this site are included

in Appendix B. At the nearest walking/working surfaces to the Sprint microwave dishes, the maximum

power density generated by the Sprint microwave dishes is approximately 1.20 percent of the FCC’s

general population limit (0.24 percent of the FCC’s occupational limit).

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. For this facility, the composite values calculated were within the allowable 100% threshold

standard per the federal government. Based on the FCC criteria, there are no measured areas on any accessible ground-level walking/working surface related to the existing site conditions that exceed the FCC’s occupational and general public exposure limits at this site.

Signage is not required because there is no access within 30 feet of an antenna. To reduce the risk of

exposure and/or injury, EBI recommends that access to the water tank or areas associated with the

active antenna installation be restricted and secured where possible.

Appendix B: Federal Communications Commission (FCC) Requirements


All information used in this report was analyzed as a percentage of current Maximum Permissible

Exposure (% MPE) as listed in the FCC OET Bulletin 65 Edition 97-01and ANSI/IEEE Std C95.1. The

FCC regulates Maximum Permissible Exposure in units of microwatts per square centimeter (µW/cm2).

The number of µW/cm2 calculated at each sample point is called the power density. The exposure limit

for power density varies depending upon the frequencies being utilized. Wireless Carriers and Paging

Services use different frequency bands each with different exposure limits, therefore it is necessary to

report results and limits in terms of percent MPE rather than power density.

All results were compared to the FCC (Federal Communications Commission) radio frequency

exposure rules, 47 CFR 1.1307(b)(1) – (b)(3), to determine compliance with the Maximum Permissible

Exposure (MPE) limits for General Population/Uncontrolled environments as defined below.

General population/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.

Public exposure to radio frequencies is regulated and enforced in units of microwatts per square

centimeter (µW/cm2). The general population exposure limit for the 700 and 800 MHz Bands is 467

µW/cm2 and 567 µW/cm2 respectively, and the general population exposure limit for the PCS and AWS

bands is 1000 µW/cm2. Because each carrier will be using different frequency bands, and each frequency

band has different exposure limits, it is necessary to report percent of MPE rather than power density.

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

population/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.

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.

Additional details can be found in FCC OET 65.
