March 8, 2017 To: Whom it May Concern Subject: Calculated Mobile Station Coupling Losses (MSCL) For FCCID: PWO460021 The following formulas were used to calculate MSCL with a 1.5’ foot path loss and a 45 degree polarity mismatch between the inside antenna and the mobile device: Path Loss dB = 36.6 dB + 20Log(F MHz) dB+ 20Log(Dmiles) dB Polarity Loss dB = 10Log(E1/E2)2 dB = PL dB 45deg PL dB= 10Log(E12/(E1Sin(45deg))2) dB = 20Log(1/Sin(45deg)) dB = 3.01dB Where: E1 = Maximum Possible Magnitude of the Electric Field from the Mobile Device E2 E1 E2 = Magnitude of the electric field from the Mobile device with a 45deg polarity mismatch = E1Sin(  MSCL dB = Path Loss dB + Polarity Loss dB - Antenna Gain dB The results of the calculations are shown in the following table: Uplink Center Frequency MHz 707-710 782 836.5 1732.5 1880-1882.5 Path Loss (dB) 22.69 23.53 24.12 30.44 31.16 Polarity Loss (dB) 3 3 3 3 3 Antenna Gain with Coax Loss -5.09 -3.55 -1.65 -1.83 -0.65 MSCL (dB) 30.78 30.08 28.77 35.27 34.81 Note: Antenna Gain with Coax Loss as measured.
