Re: FCC ID: PWO 460054

To Whom It May Concern:

The MPE calculations for model 460054 signal booster were done for each frequency band: 700 MHz
Band 12, 700 MHz Band 13, 800 MHz, 1900 MHz, and 1700/2100 MHz. For each band one calculation
was done; this included mobile outside antenna, and mobile inside antenna that may be connected to
this signal booster. The order of the attached calculations is as follows:

       700 MHz Band 12:
              1. Inside Antenna: ANT000006        2. Outside Antenna: 301114
       700 MHz Band 13:
             1. Inside Antenna: ANT000006         2. Outside Antenna: 314203
       800 MHz band:
             1. Inside Antenna: ANT000006         2. Outside Antenna: 314203‐5810
       1900 MHz band:
              1. Inside Antenna: ANT000006        2. Outside Antenna: 301114
       1700/2100 MHz band:
              1. Inside Antenna: ANT000006        2. Outside Antenna: 301114

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))
