Calgary Communicator Model 7000C FCC ID: BDZ7000C IC: 655C‐7000C Prediction of MPE The device is designed as module to be installed in other devices. This device is to be used only for fixed and mobile applications. If the final product after integration is intended for portable use, a new application and FCC is required. The antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all the persons and must not be co-located or operating in conjunction with any other antenna or transmitter. The table below is excerpted from Table 1B of 47 CFR 1.1310 titled Limits for Maximum Permissible Exposure (MPE) and Health Canada Safety Code 6, Limits for General Population/Uncontrolled Exposure: Frequency Range (MHz) Power density (mW/cm2) Averaging time (minutes) 300 – 1500 f (MHz) /1500 30 1500 – 100.000 1.0 30 Based on the above table the limits are: For 850 MHz frequency band device: 0.57 mW/cm2 For 1700 /1900 MHz frequency band device: 1 mW/cm2 FCC § 2.1091 / IC RSS102, section 2.5.2 The limit for 850 MHz mobile operations where no routine evaluation is required is: 1.5W ERP The limit for 1700 / 1900 MHz mobile operations where no routine evaluation is required is: 3W EIRP Max permissive power according to §24.232 and RSS133: 2W EIRP Max permissive power according to §§22.913(a) and RSS132: 7W ERP Using the equation from page 19 of OET Bulletin 65, Edition 97-01: PG S = where: S = power density (in appropriate units, e.g. mW/cm2) π 4 R 2 P = power input to the antenna (in appropriate units, e.g., mW) G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna (appropriate units, e.g., cm) 850 MHz frequency band Maximum output power considerations: M i Maximum Equivalent conducted output conducted Maximum conducted output power Mode Duty cycle power (Maximum conducted output power (W) output power x duty cycle) (mW) (dBm) GPRS 32,67 1,849 50% 925 EDGE 27,3 0,537 50% 269 WCDMA 23,15 0,207 100% 207 P p Maximum power p to the antenna: input 925 mW R Distance: 20 cm 2 S MPE limit for uncontrolled exposure: 0,57 mW/cm G1 Antenna gain (dBi) to comply with MPE limits: 4,91 dBi ERP power limit according to §2.1091: 1,50 W ERP G2 Antenna gain (dBi) to comply with ERP limits: 4,25 dBi (ERP[dB] = Maximum conducted output power [dB]x Antenna gain [dBi]-2,15) ERP power limit according to §22.913: 7,00 W ERP G3 Antenna gain (dBi) to comply with ERP limits: 7,93 dBi (ERP = Maximum conducted output power x Antenna gain / 1,64) G850 MHz band Min (G1, G2, G3) 4,25 dBi Therefore the maximum antenna gain for mobile operation to comply with MPE and ERP limits shall not exceed: 4,25 dBi MPE_LISA_U200.xlsx 1/2

1900 MHz frequency band Maximum output power considerations: Maximum Equivalent conducted output conducted Maximum conducted output power Mode Duty cycle power (Maximum conducted output power (W) output power x duty cycle) (mW) (dBm) GPRS 30,27 1,064 50% 532 EDGE 26,47 0,444 50% 222 WCDMA 23,73 0,236 100% 236 P Maximum power input to the antenna: 532 mW R Distance: 20 cm 2 S MPE limit for uncontrolled exposure: 1,00 mW/cm G1 Antenna gain (dBi) to comply with MPE limits: 9,75 dBi ERP power limit according to §2.1091: 3,00 W ERP G2 Antenna gain (dBi) to comply with ERP limits: 9,66 dBi (ERP[dB] = Maximum conducted output power [dB]x Antenna gain [dBi]-2,15) ERP power limit according to §24.232 2,00 W EIRP G3 Antenna gain (dBi) to comply with EIRP limits: 2,74 dBi (EIRP = Maximum conducted output power x Antenna gain ) G1900 MHz band Min (G1, G2, G3) 2,74 dBi Therefore the maximum antenna gain for mobile operation to comply with MPE and EIRP limits shall not exceed: 2,74 dBi MPE_LISA_U200.xlsx 2/2
