Emissions Analysis for Site: BOBOS00022A - BOBOS00022A EBI Consulting was directed to analyze the proposed Dish Wireless facility located at 1337 Route 65 in Montville, Connecticut for the purpose of determining whether the emissions from the Proposed Dish Wireless 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-Oland ANSI/IEEE Std C95.1. The FCC regulates Maximum Permissible Exposure in units of rnicrowatts pet, square centimeter (pW/cmz). The number of pW/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 I ules, 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. mineral population/uricontr'olled Exposure limits apply to situations in which the general population may be exposed or in which persons who are exposed as it 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 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 rnicrowatts per square centimeter (pW/cmz). The general population exposure limits for the 600 MHz and 700 MHz frequency bands are approximately 400 pW/cmz and 467 µW/cmz, respectively. The general population exposure limit for the 1900 MHz (PCS), 2100 MHz (AWS) and I I GHz frequency bands is 1000 µW/crnz. Because each carrier will be using different frequency bands, and each frequency band has different exposure limits, it is necessary to repots percent of MPE rather than power density. Occqpationa_I/contr_olled gxpostn_e 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. EIEU Consulting - environmental j engineering I due diligence 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 rnade 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. Calculations were done for the proposed Dish Wireless Wireless antenna facility located at 1337 Route 85 in Montville, Connecticut using the equipment information listed below. All calculations were performed per the specifications under FCC OET 65. Since Dish Wireless is proposing highly focused directional panel antennas, which project most of the emitted energy out toward the horizon, all calculations were performed assuming a lobe representing the maximurn gain of the antenna per the antenna manufacturer's supplied specifications, minus 20 dB for directional panel antennas and 20 dB for highly focused parabolic microwave dishes, was focused at the base of the tower. For this report, the sample point is the top of a 6-foot person standing at the base of the tower. For all calculations, all equipment was calculated using the following assumptions: 1) 4 n71 channels (600 MHz Band) were considered for each sector of the proposed installation. These Channels have a transmit power of 30 Watts per Channel, 2) 4 n70 channels (PCS Band - 1900 MHz) were considered for each sector of the proposed installation. These Channels have a transmit power of 40 Watts per Channel. 3) 4 n66 channels (AWS Band - 2190 MHz) were considered for each sector of the proposed installation. These Channels have a transmit power of 40 Watts per Channel. 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 OFT 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 6-foot person standing at the base of the tower. The maximum gain of the antenna per the antenna manufacturer's supplied specifications, minus 20 dB for directional panel antennas and 20 dB for highly focused parabolic microwave dishes, was used in this direction. This value is a very conservative 21 t a di, liu,lni„uni, GAP.fW'O 1 rl (/1;1)1/I ( ,i) )/;'! ;II 5 9 ,. -� t�n+�ironiiteuf,ai � amginet�ring (dur^dilit;enct:. estimate as gain reductions for these particular antennas are typically much higher in this direction. 6) The antennas used in this modeling are the Commscope FFVV-65B-R2 for the 600 MHz / 1900 MHz 12190 MHz channel(s) in Sector A, the Commscope FFVV-65B-R2 for, the 600 MHz / 1900 MHz / 2190 MHz channel(s) in Sector- B, the Commscope FFVV-6.5B-R2 for the 600 MHz / 1900 MFlz / 2190 MHz channel(s) in Sector C. This is based on feedback from the cat•t-ier with regard to anticipated antenna selection. All Antenna gain values and associated transmit power- levels are shown in the Site Inventory and Power Data table below. The maximum gain of the antenna per the antenna manufactun-et's supplied specifications, minus 20 dB for, directional panel antennas and 20 dB for- highly focused parabolic microwave dishes, was used for all calculations. This value is a very conservative estimate as gain reductions for - these. particular antennas are typically much higher- in this direction. 7) The antenna mounting height centerline of the proposed antennas is 180 feet above ground level (AGL). 8) Emissions values for additional carriers were taken f -can the Connecticut Siting Council active database. Values in this database ar-e provided by the individual carriers thernselves. 9) All calculations were done with respect to uncontrolled / general population threshold lirnits. i ri,;ii o��,�' an; I, i ,r �'W ""E[fll Consulting environmental I engineering I dua. diligence INTITHIM Sector: A Sector: B `..

The anticipated maximum composite contributions from the Dish Wireless facility as well as the site composite emissions value with regards to compliance with FCC's allowable limits for general population exposure to RF Emissions are shown here: Dish Wireless Sector Power Density Value (%) Sector A: 0.75% --- Sector 6: — -- 0.75% Sector C: --- 0.75% - — Dish Wireless-- — Maximum MPE % (Sector, A): — — -- 0.75% Site Total: _— 4.66%'' Site Compliance Status: COMPLIANT IANT The anticipated composite MPE value for this site assuming all carriers present is 4.66% of the allowable FCC established general population 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 S% contribution to the composite value will require measures to bring the site into compliance. For this facility, the composite values calculated were well within the allowable 100% threshold standard per the federal government.
