MG323 Electromagnetic Radiation Exposure Estimation 1 Maximum Permissible Exposure (MPE) Estimation for MG323 1 Introduction MG323 GSM/GPRS M2M Module is subscriber equipment in the GSM/GPRS system.The GSM/GPRS frequency bands include EGSM850 and PCS1900. MG323 implement such functions as RF signal receiving / transmitting, GPRS/GSM protocol processing, data service etc. Externally they provide 50pin B2B interface. 2 Limits and Guidelines on Exposure to Electromagnetic Fields According to the FCC Part 2.1091( which reference the part1.1310), we know: mobile device (transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitters radiating structure(s) and the body of the user or nearby persons). And the Cellular radiotelephone service and PCS services are subject to routine environmental evaluation for RF exposure prior to equipment authorization or use if they operate at frequencies of 1.5 GHz or below and their effective radiated power (ERP) is 1.5 watts or more, or if they operate at frequencies above 1.5 GHz and their ERP is 3 watts or more. Uncontrolled limits are used for general public. General population/uncontrolled exposure apply in situations is which the general public may be exposed, or in which persons that are exposed as a consequence of their employment may not be fully aware of the potential for exposure or can not exercise control over their exposure. The exposure levels can be expressed in terms of power density, electric field strength, or magnetic field strength, as averaged over 30 minutes for the general public and 6 minutes for trained personnel. The exposure criterion is frequency dependent, and a chart covering the range from 3 kHz to 100 GHz can be found in NCRP No.86 (references IEEE C95.1-1999). Below are the limits. Limits for Occupational/Controlled Exposure Frequency Range (MHz) Electric Field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) (mW/cm 2 ) 0.3-3.0 3.0-30 30-300 300-1500 15,00-100,000 614 1842/f 61.4 -- -- 16.3/f 16.3/f 0.163 -- -- (100)* (900/f 2 )* 1.0 f/300 5 MG323 Electromagnetic Radiation Exposure Estimation 2 Limits for General Population/Uncontrolled Exposure Frequency Range (MHz) Electric Field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) (mW/cm 2 ) 0.3-1.34 1.34-30.0 30-300 300-1500 15,00-100,000 614 824/f 27.5 -- -- 1.63 2.19/f 0.073 -- -- (100)* (180/f 2 )* 0.2 f/1500 1 Power density S [mW/cm2] for controlled area at 850 MHz ，(TX: 824MHz – 849MHz) 75.2 300 824 300 )( === MHzf S mW/cm 2 Power density S [mW/cm2] for uncontrolled area at 824 MHz 55.0 1500 824 1500 )( === MHzf S mW/cm 2 Power density S [mW/cm2] for uncontrolled area at 1900 MHz S=1 mW/cm 2 Reference levels are provided for exposure assessment to determine whether the basic restrictions on exposure of humans to electromagnetic fields are exceeded. The basic restrictions on exposure to electromagnetic fields are based directly on established health effects and biological considerations. 3 Location of EUT The source of the radiation is mounted on terminal; generally the direction of the antenna position is uprightness tabletop. The highest level of emission would be expected in close vicinity of the antenna and in line of sight to the antenna. 4 Prediction of the Exposure to Electromagnetic Fields Calculations can be made on a site by site basis to ensure the power density is below the limits given above, or guidelines can be done beforehand to ensure the minimum distances from the antenna is maintained through the site planning. The calculations are based on FCC OET 65 Appendix B. MG323 Electromagnetic Radiation Exposure Estimation 3 4.1 Calculation of the Safe Distance Below method describes a theoretical approach to calculate possible exposure to electromagnetic radiation around a base station transceiver antenna. Precise statements are basically only possible either with measurements or complex calculations considering the complexity of the environment (e.g. soil conditions, near buildings and other obstacles) which causes reflections, scattering of electromagnetic fields. The maximum output power (given in EIRP) of a base station is usually limited by license conditions of the network operator. A rough estimation of the expected exposure in power flux density on a given point can be made with the following equation. The calculations are based on FCC OET 65 Appendix B. π∗∗ ∗ = )(4 )( 2 mr GWP S numeric Whereas: P = Maximum output power in W of the site G numeric = Numeric gain of the antenna relative to isotropic antenna R = distance between the antenna and the point of exposure in meters 4.2 Technical Description MG323 Technical Specification: Cellular Band Power at antenna connector BTS: 31.3 dBm (GSM850) Antenna-cable attenuation: 0 dB Input power to antenna: 31.3 dBm（1.35W）(GSM850) Antenna gain: 4.28 dBi (2.68) MG323 Electromagnetic Radiation Exposure Estimation 4 PCS Band Power at antenna connector BTS: 29.87 dBm (PCS1900) Antenna-cable attenuation: 0 dB Input power to antenna: 29.87 dBm （0.97W）(PCS1900) Antenna gain: 3 dBi (2.0W) 4.3 Estimation of compliance boundary for indoor antenna 1) Cellular Band : GSM850 For the final determination of the compliance boundary the model for far-field calculation is used since this overestimates the field strength in the near-field region. Thus the calculated compliance boundary should be rather more conservative and on the safe side. For EUT the following compliance boundary is calculated: Compliance boundary For GSM 850MHz band: When r=20cm and GSM only use one timeslot, so π∗∗ ∗ = )(4*8 )( 2 timeslotone mr GWP S numeric π∗∗ = 2 timeslotone 204*8 68.2*1350 S =0.090 mW/cm 2 For GPRS, the transmitter support multi-timeslot, but the conducted ERP will decrease 2dB when add one uplink timeslot, so we can get the following conclusion: The …
