J. THOMAS, P.E. 7607 80th Ave NE Marysville, WA 98270 (206) 851-1106 PROJECT The proposed T-Mobile project consists of a WCF (Wireless Communications Facility) with BTS equipment located on private property at 2649 S Star Lake Road, Federal Way, WA 98003, King county tax parcel 7204800041. The planned improvements include (6) replacement/new panel antennas on a 103.8’ water tank with supporting BTS (Base Transmission System) at ground level. EQUIPMENT Type of Service: N600, L600, L700, L1900, L2100, L2500 & N2500 Antennas: Commscope FFVV-65C-R3-V1 & Nokia AEHC Sectors: 3 (alpha = 140°, beta = 220°, gamma = 310°) Antenna Rad Center: 104’ 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/πR² Where S = power density (mW/cm²), EIRP = equivalent isotropically radiated power and R = distance to the center of the radiation antenna (cm) Attached as an exhibit are the MPE (Maximum Permissible Exposure) calculations using the above referenced formula and the antenna manufacturer vertical pattern information using a conservative 20 dB loss below main lobe. The calculations show that the maximum MPE at ground level (6’ above AGL) at the base of the water tank and the power density is 0.00103 mW/cm² with power levels provided by T-Mobile RF engineer. This is 1.16% of the MPE limit for SE04227A HERITAGE WOODS PARK-HGHLN WTR DT-SE53XC241-SPRINT RETAINMPE CalculationsGeneral Population-Uncontrolled ExposureGround LevelEffective tower height assumes a person 6 ft tall.Calble losses neglible as 15' or less SF coax jumpers are usedeffectiveradiation towerantenna TX ERP ERP power at point xpercentageBands Transmitter Techmology center height minor lobedB below horiz. dist. hyptonuse hypotenuse hypotenuse gain main lobe main lobe main lobe minor lobe minor lobe minor lobe at ground levelof(feet), y (feet), y angle main lobe x length (feet) length (km) length (cm) (dBi) (watts) (watts) (dBm) ERP (dBm) EIRP (dBm) EIRP (mW) mW/cm^2standard12 & 17 AHLOA 4G/5G 104 98 90 20 0.000 98.000 0.030 2987.040 14.00 96.000 1472 61.68 41.68 43.84 24205.15 0.0009 0.22%25 & 66 AHFIG 2G/3G/4G 104 98 90 20 0.000 98.000 0.030 2987.040 18.31 320.000 13243 71.22 51.22 53.38 217764.15 0.0078 0.78%41 AEHC 4G/5G 104 98 90 20 0.000 98.000 0.030 2987.040 18.00 74.000 2851 64.55 44.55 46.71 46881.04 0.0017 0.17%TOTAL 0.0103 1.16%horiz.
