July 7, 2017 Subject: RF MPE EXPOSURE Re: FCC ID: PWO460035 To Whom It May Concern: The MPE calculations for model 460035 signal booster were done for each frequency band: 700 MHz Band 12, 700 MHz Band 13, 800 MHz, 1900 MHz, and 1700 MHz. For each band one calculation ws done; this included the worst case scenario for each of mobile outside antennas that may be connected to this signal booster. The order of the attached calculations is as follows: 700 MHz Band 12: 1. Outside Antenna: 304415 700 MHz Band 13: 1. Outside Antenna: 304415 800 MHz band: 1. Outside Antenna: 311104 1900 MHz band: 1. Outside Antenna: 311101 1700MHz band: 1. Outside Antenna: 304415 A booster’s uplink power must not exceed 1 watt equivalent isotropic radiated power (EIRP) for each band of operation. Composite downlink power must not exceed 0.05 watt EIRP for each band of operation (20.21(e)(8)(i)(D)). The following formula was used to calculate the equivalent isotropic radiated power: EIRP= Power Out (Watts)*Duty Cycle Percent*Antenna Gain (non‐log)*Coax loss (non‐log) The power density (mW/cm2) is calculated using the following formula: Calculated Power Density=1000*EIRP (Watts)/(4*π*(Distance from Antenna (cm)^2)) Sincerely, Patrick L. Cook Chief Technology Officer
