Park Drive Westborough, MA 01581 1# FOX HILL TELECOM Emissions Analysis for: Crown Castle Site: 876370 — Maybrook / Bond Verizon Wireless Site: Chesterfield CT Fox Hill Telecom, Inc ("Fox Hill") was directed to analyze the proposed upgrades for Verizon Wireless to the Crown Castle facility located at 41 Beckwith Road, Montville, CT, for the purpose of determining whether the emissions from the Proposed Verizon Wireless Antenna Installation, in addition to all existing radio systems 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 ANSUIEEE Std C95.1. The FCC regulates Maximum Permissible Exposure in units of microwatts per square centimeter (µW/cm2). The number of µW/cmZ 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 population may be exposed or in which people 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 population would always be considered tinder this category when exposure is not employment related, for example, in the case of a telecommunications tower that exposes people in a nearby residential area. Fox Hill Telecom. Inc Worcester MA 01609 FOX HILL TELECOM General population exposure to radio frequencies is regulated and enforced in units of microwatts per square centimeter (µW/cm2). The general population exposure limits for the 700 MHz band & the 850 MHz cellular band are approximately 497 µW/cm2 and 586 µW/cmZ respectively. The general population exposure limit for the 1900 MHz (PCS), 2100 MHz (AWS) and 3700 MHz (C band) frequency 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 the percentage of MPE rather than power density. Occupational/controlled exposure limits apply to situations in which people are exposed as a consequence of their employment and in which those people who are exposed have been made fully aware of the potential for exposure and can exercise control over their exposure. Occupational1controlled 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. Additional details can be found in FCC OFT 65. Fox Hill Telecom, Inc Worcester MA 01609 FOX HILL TELECOM CALCULATIONS Calculations were performed for the proposed upgrades to the Crown Castle facility for Verizon Wireless located at 41 Beckwith Road, Montville, CT, using the equipment information listed below. All calculations were performed per the specifications tinder FCC OET 65 for far field modeling calculations In OET-65, power density values in the Far Field of an antemta are calculated by considering the transmit power in each band specified and multiplied by the antetma gain values per the antenna manufacturer specifications. Since the radiation pattern of an antenna has developed in the Far Field region, the power gain in specific directions needs to be considered in exposure predictions to yield an Effective Radiated Power (ERP) in each specific direction from the antenna. Also, since the vertical radiation pattern of the antenna is considered, the exposure calculations would most likely be reduced at ground level, when compared to an isotropic model, resulting in a more realistic estimate of the actual exposure levels. A worst -case Far Field prediction is described in OET-65 where field strength may double due to 100% reflection of the incoming radiation. Considering an EPA recommendation that a multiplier of 1.6 is a more realistically representation of this effect is rewritten as follows: 33.4 • Pi, - GaBa / 'SFF — Rz \itW/�m2) • SFr = Power Density (in µW/cm2) • Pin is Watts • R is meters to study point • G is gain to study point as specified in manufacturer horizontal and vertical patterns This model calculates the power density at a single point in space. In order to determine the spatial power density for comparison to the FCC limits, the average of several points calculated within the human profile (0 to 6 feet) must be conducted. Seven power density values, between 0 and 6 feet above the specified study plane at each point, were calculated and a linear spatial average of these values was used to create the spatially averaged result for that point on the plane.

FCC OFT 65 specifies that for carriers utilizing directional antennas the highest recorded sector value be used for composite site emissions values due to their greatly reduced emissions contributions in the directions of the adjacent sectors. For this site, all three Verizon Wireless sectors have the same configuration, yielding the same results for all three sectors.

The anticipated maximum composite contributions from the Verizon Wireless facility as well as the site composite emissions estimates value with regards to compliance with FCC's allowable limits for general population exposure to RF Emissions are shown here: Verizon Wireless Sector Power Density Value Sector A: 1.42 % Sector B: 0.00 % Sector C: 0.00 % Verizon Wireless Maximum Total(per sector): 1 42 % Site Total: 2.96 % Site Compliance Status: COMPLIANT The estimated composite emissions value for this site, assuming all carriers present, is 2.96 % of the allowable FCC established general population limit sampled at the ground level. This is based upon the far field calculations performed for all carriers identified in this report. 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 estimated values calculated were well within the allowable 100% threshold standard per the federal government.
