4     Annex A: MPE calculation

4.1 Antenna configurations

The EUT can be used with different antenna configurations:
        -   Internal PCB-antenna
        -   Omni-directional antenna
        -   Portable antenna (only 850 MHz-band)
        -   Yagi antenna (only 850 MHz-band)
The EUT is equipped with a switching MCX-connector to switch between internal and external antenna.

Maximum conducted output power configurations:
        850 MHz:          GPRS multi-slot class 12            1.446 W
        1900 MHz:         GPRS multi-slot class 12            0.468 W

Maximum antenna gain for internal PCB-antenna
        850 MHz:          Gain -0.2 dBi
        1900 MHz:         Gain 0.5 dBi

Maximum antenna Gain for Omni-directional antenna (datasheet in chapter 4.3.1)
        850 MHz:          Gain 5.12 dBi
        1900 MHz:         Gain 6.12 dBi
        This antenna will be delivered with one 30 ft antenna cable. (30 feet RG58 coax with FME male and FME
        female connector)

        So the effective gain can be calculated as follows:

        Gain = Gain(Antenna) – Attenuation(cable)

        850 MHz:          Gain(eff) = 5.12 dBi – 2.27 dB = 2.85 dBi
        1900 MHz:         Gain(eff) = 6.12 dBi – 3.21 dB = 2.91 dBi

Maximum antenna Gain for Portable antenna (datasheets in chapter 4.3.2)
        850 MHz:          Gain 4.5 dBi

Maximum antenna Gain for Yagi-antenna (datasheets in chapter 4.3.3)
        850 MHz:          Gain 10.0 dBi     (antenna)
        This antenna will be delivered with two 30 ft antenna cables. (1 x ft 30 feet RG58 low loss coax with N-male
        and FME-female connector (cable 1) and 30 feet RG58 coax with FME- male and FME-female connector
        (cable 2))

        So the effective gain can be calculated as follows:

        Gain = Gain(Antenna) – Attenuation(cable 1) – Attenuation(cable 2)

        850 MHz:          Gain(eff) = 10 dBi – 2.27 dB – 2.27 dB = 5.46 dBi

4.2 MPE calculation

Maximum possible radiated output power configurations

    850 MHz:    31.6 dBm + 5.46 dBi = 37.06 dBm = 5081 mW (EIRP) = 3104 mW (ERP)   (with Yagi-antenna)

    1900 MHz: 28.3 dBm + 2.91 dBi = 31.21 dBm = 1321 mW (EIRP)                     (with Omni-directional
                                                                                   antenna)




Maximum permissive exposure (MPE)

       850 MHz:        Limit 0.57 mW/cm²

                                PD = Prad * DF / (4 * Л * r²)

                                PD = 5081 mW * 0.5 / (4 * Л * 20² cm²)

                                PD = 0.505 mW/cm²

       Result: The device complies with the rules for a distance of 20 cm.


       1900 MHz:       Limit 1.00 mW/cm²

                                PD = Prad * DF / (4 * Л * r²)

                                PD = 1321 mW * 0.5 / (4 * Л * 20² cm²)

                                PD = 0.131 mW/cm²

       Result: The device complies with the rules for a distance of 20 cm.


       PD = Power Density
       Prad = Maximum radiated output power in mW
       DF = Duty factor
       r = Distance in cm
