Re: Emissions Values for Site: CT11443E - Gridcom Stonehart

EBI Consulting was directed to analyze the proposed T-Mobile facility located at 17 Cottage Street,

Madison, CT, for the purpose of determining whether the emissions from the Proposed T-Mobile Antenna

Installation located on this property are within specified federal limits.

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 cellular band is 567 µW/cm2, 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.

CALCULATIONS

Calculations were done for the proposed T-Mobile Wireless antenna facility located at 17 Cottage Street,

Madison, CT, using the equipment information listed below. All calculations were performed per the

specifications under FCC OET 65. Since T-Mobile is proposing highly focused directional panel

antennas, which project most of the emitted energy out toward the horizon, the actual antenna pattern gain

value in the direction of the sample area was used. For this report the sample point is a 6 foot person

standing at the base of the tower

For all calculations, all equipment was calculated using the following assumptions:

1) 2 GSM channels (1935.000 MHz—to 1945.000 MHz / 1980.000 MHz—to 1985.000 MHz)

were considered for each sector of the proposed installation.

2) 2 UMTS channels (2110.000 to 2120.000 MHz / 2140.000 MHz to 2145.000 MHz) were

considered for each sector of the proposed installation.

3) 2 LTE channels (2110.000 to 2120.000 MHz / 2140.000 MHz to 2145.000 MHz) were

considered for each sector of the proposed installation.

4) All radios at the proposed installation were considered to be running at full power and were

uncombined in their RF transmissions paths per carrier prescribed configuration. Per FCC

OET Bulletin No. 65 - Edition 97-01 recommendations to achieve the maximum anticipated

value at each sample point, all power levels emitting from the proposed antenna installation

are increased by a factor of 2.56 to account for possible in-phase reflections from the

surrounding environment. This is rarely the case, and if so, is never continuous.

5) For the following calculations the sample point was the top of a six foot person standing at

the base of the tower. The actual gain in this direction was used per the manufactures

supplied specifications.

6) The antenna used in this modeling is the Ericsson AIR21 for LTE, UMTS and GSM. This is

based on feedback from the carrier with regards to anticipated antenna selection. This antenna

has a 15.6 dBd gain value at its main lobe. Actual antenna gain values were used for all

calculations as per the manufacturers specifications

7) The antenna mounting height centerline of the proposed antennas is 117 feet above ground

level (AGL)

8) Emissions values for additional carriers were taken from the Connecticut Siting Council

active database. Values in this database are provided by the individual carriers themselves.

All calculation were done with respect to uncontrolled / general public threshold limits

Summary

All calculations performed for this analysis yielded results that were well within the allowable limits for

general public exposure to RF Emissions.

The anticipated Maximum Composite contributions from the T-Mobile facility are 0.846% (0.282%

from each sector) of the allowable FCC established general public limit considering all three sectors

simultaneously sampled at the ground level.

The anticipated composite MPE value for this site assuming all carriers present is 11.576% of the

allowable FCC established general public limit sampled at the ground level. This is based upon values

listed in the Connecticut Siting Council database for existing carrier emissions.

FCC guidelines state that if a site is found to be out of compliance (over allowable thresholds), that

carriers over a 5% contribution to the composite value will require measures to bring the site into

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

standard per the federal government.
