� <br />PROJECT <br />The proposed AT&T project consists of a WCF (V��reless Communications <br />Facility) located at 906 SE Everett Mall Way, Everett, WA 98208, Snohomish <br />County tax parcel 18280530850005. The planned improvements include (3) <br />panel antennas for LTF. servic� on an existing building rooftop with supporting <br />BTS (Base Transmission System) radio equipment also on the rooftop at an on- <br />air AT&T site. <br />EQUIPMEN7 <br />Type of Service: GSM 190U, UMTS '1900, GSM 850, UMTS 850, LTE 700 <br />Antennas: Kathrein 80010764 & 80010766 <br />Powervvave AM-X-CD-16-65-OOT-RET <br />Sectors: (3) (X = 125° &140°, Y= 235° & 25U°, Z= 35° & 50°) <br />Maximum Power: GSM 850 - 618 w(57.91 dBm ERP) <br />GSM 1900 - 1140w (60.57 dBm ERP) <br />UMTS 850 — 498 w(56.y8 tlSm ERP) <br />UMTS 1900 — 872 w(59.41 dBm ERP) <br />LTE 700 - 716 w(58.55 dBm ERP) <br />Antenna Rad Center: 80' AGL <br />CALCULATIONS <br />Calculations for RF power densities near ground level are based on the <br />"Evaluating Compliance with FCC Guidelines for Human Exposure to Radio <br />Frequency Electromagnetic Fields OET Bulletin 65" Edition 97-01, August <br />1997 issued by the Federal Communications Commission Office of Engineering <br />& Technology. <br />Section 2 of OET Bulletin 65 demonstrates that "for a truly worst-case prediction <br />of power density at or near the surface, such as at ground-level or on a rooftop, <br />1U0% reflection of incoming radiation can be assumed, resulting in a potential <br />doubling of pred�cted field strength and a four-fold increase in (far field <br />equivalent) power density". Therefore the followina equation is used: <br />S = EIRP/TrRz <br />Where S= power density (mW/cmZ), EIRP = equivalent isotropically radiated <br />power and R= distance to the center of the radiation antenna (cm) <br />
