Huawei B681-54 Electromagnetic Radiation Exposure Estimation SECRET 1 Maximum Permissible Exposure (MPE) Estimation for 1 Introduction The HUAWEI wireless gateway B681-54 (hereinafter referred to as the B681-54) is a wireless HSPA+3G gateway, which provides users with flexible and diversified 3G and 2G data access services, routing function, and network address translation (NAT) function. The WCDMA frequency is Band II and Band V. The GSM frequency is GSM850/ 1900.The WLAN frequency is 2.4G. GSM850 transmit frequency is 824-849MHZ,and Receive Frequency is 869-894MHZ ;GSM1900 transmit frequency is 1850-1910MHZ,and Receive Frequency is 1930-1990 MHZ;WCDMA 1900 transmit frequency is 1850-1910MHZ,and Receive Frequency is 1930-1990MHZ. The WLAN frequency range is 2400-2483.5MHZ。WCDMA 850 transmit frequency is 824-849MHZ .and Receive Frequency is 869-894MHz. B681-54 implements such functions as RF signal receiving/transmitting, HSPA+ / WCDMA / GPRS/EDGE protocol processing, data service, etc. Externally it provides USB type B interface（For power supply）, USIM card interface, two auto-sensing Ethernet interfaces and external antenna interface. And RJ11 interface (to connect to fixed telephone), provide voice service. 2 Limits and Guidelines on Exposure to Electromagnetic Fields According to the FCC Part 2.1091, 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 above and their effective radiated power (ERP) is 1.5 watts or more, or if they operate at frequencies below 1.5 GHz and their ERP is 3 watts or more. The maximum radiated power of 850MHz for B681-54 is 2.52W, the maximum radiated power of 1900MHz for B681-54 is 1.26W, and the maximum radiated power of 2400MHz for B681-54 is 0.1W. So the B681-54 is excluded from routine environmental evaluation for RF exposure according to the requirement of FCC Part 2.1091. The present document is given just only for reference. Huawei B681-54 Electromagnetic Radiation Exposure Estimation SECRET 2 Uncontrolled limits are used for general public. General population/uncontrolled exposure apply in situations in 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/cm2) 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/f2)* 1.0 f/300 5 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/cm2) 0.3-1.34 1.34-30 30-300 300-15,00 15,00-100,000 614 824/f 27.5 -- -- 1.63 2.19/f 0.073 -- -- (100)* (180/f2)* 0.2 f/1500 1.0 For GSM/WCDMA 850M Power density S [mW/cm2] for controlled area at 800 MHz 57.2 300 428 300 )(  MHzf S mW/cm 2 Power density S [mW/cm2] for uncontrolled area at 800 MHz Huawei B681-54 Electromagnetic Radiation Exposure Estimation SECRET 3 945.0 1500 824 1500 )(  MHzf S mW/cm 2 S= 0.549 mW/cm 2 = 5.49 W/m 2 for uncontrolled exposure For GSM/WCDMA 1900M, WLAN2400M Power density S [mW/cm2] for controlled area at 1900/2400 MHz 5S mW/cm 2 Power density S [mW/cm2] for uncontrolled area at 1900/2400 MHz 0.1S mW/cm 2 S= 1.0 mW/cm 2 = 10 W/m 2 for uncontrolled exposure 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 EUT uses one omnidirectional antenna. The source of the radiation is mounted on board of the terminal. The highest level of emission would be expected in close vicinity of 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. 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. Huawei B681-54 Electromagnetic Radiation Exposure Estimation SECRET 4 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.
