2930 WETMORE AVE T MOBILE ANTENNAS 2019-05-02

PROJECT The proposed T-Mobile project consists of a WCF (Wireless Communications Facility) with BTS equipment located on private property at 2930 Wetmore Avenue, Everett, WA 98201, Snohomish County tax parcel 00439171700100. The planned improvements include relocated antennas mounted on an existing building rooftop with supporting BTS (Base Transmission System) radio equipment also on the building rooftop. EQUIPMENT Type of Service: Broadband PCS Antennas: Andrew TMBXX Frequencies: Send (1965 Mhz - 1975 Mhz, 1980 Mhz — 1985 mMhz) Receive (1885 Mhz - 1895 Mhz, 1900 Mhz — 1905 Mhz) Antenna Rad Center: 109'- 11" AGL CALCULATIONS Calculations for RF power densities near ground level are based on the "Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields OET Bulletin 65" Edition 97-01, August 1997 issued by the Federal Communications Commission Office of Engineering & Technology. Section 2 of OET Bulletin 65 demonstrates that "for a truly worst-case prediction of power density at or near the surface, such as at ground-level or on a rooftop, 100% reflection of incoming radiation can be assumed, resulting in a potential doubling of predicted field strength and a four-fold increase in (far field equivalent) power density". Therefore the following equation is used: S = EIRP/rrRZ Where S= power density (mW/cmZ), EIRP = equivalent isotropically radiated power and R= distance to the center of the radiation antenna (cm) Attached as an exhibit are the MPE (Maximum Power Exposure) calculations using the above referenced formula and the antenna manufacturer vertical pattern information using an assumed worst case power level of 2,000 watts. The calculations show that the maximum MPE at ground level (6' above AGL) occurs with the antenna and the power density is 0.001961 mW/cmZ with an assumed power level of 2,000 watts. This is 0.1961 % of the MPE limit for the �
