MU203 SECRET Page1,Total 6 Introduction The MU203 Wireless Module developed independently by HUAWEI based on the 6240 chipset produced by QUALCOMM Incorporated. It supports GSM/GPRS/EDGE frequency bands.It is designed in compliance with the FCC Rules and Regulations Part 24 and Part22. Intended use statements MU203 is a Wireless Module. It can only be work in the networks which it supports the EDGE/GPRS/GSM technique. If there are no corresponding networks, the RF module of MU203 will not work and no any unwanted emission will be produced. Types of Emissions For this Wireless module, the emission designator is 300KGXW Frequency Range GSM/GPRS/EDGE 850MHz: 824～849MHz GSM/GPRS/EDGE 1900MHz:1850~1910MHz Range of Operating Power The peak output power of a this handset may not exceed 2 Watts EIRP for 1900M as defined in Part 24 The peak output power of a this handset may not exceed 7 Watts ERP for 850M as defined in Part 22 Maximum Power Limits 850MHz: GSM/GPRS: 33dBm [+/-2dB] EDGE: 27 dBm [+/-3dB] 1900MHz: GSM/GPRS: 30dBm [+/-2dB] EDGE: 26 dBm [+/-3dB] MU203 SECRET Page2,Total 6 Antenna description Technical parameters of the Huawei MU203 Wireless Module antenna: Item Description Frequency 850MHz/1900 MHz Input impedance 50 Ohm VSWR ≤ 3 Peak gain 850M:<4.28dBi 1900M:<2.1dBi Rated power 4 W Polarization Linear Applied voltages Normal Voltage: 3.8V Low Voltage: 3.3V High Voltage: 4.2V Complete bill of material Attachment Complete Circuit Diagrams Attachment Instruction/Installation Manual Attachment Means for Frequency Stabilization The QSC6240 is mainly responsible for the frequency stabilization. The QSC6240 receives the BS signal and demodulates it and then generates the local clock to provide the system with various clock signals. Means for Limiting Modulation In a GSM system, the input signal (voice for example) is sampled and coded in a vocoder, after channel coding, The digital signal is modulated onto the analog carrier frequency using Gaussian-filtered Minimum Shift Keying (GMSK). The modulation scheme is MU203 SECRET Page3,Total 6 gaussian MSK (GMSK) with BT=0.3. The modulation rate is 1625/6 kbit/s (270,83kbit/s). GMSK was selected over other modulation schemes as a compromise between spectral efficiency, complexity of the transmitter, and limited spurious emissions. The modulation standard selected for EDGE is 8-phase shift keying (8PSK). 8PSK was selected over other modulation schemes as a compromise between spectral efficiency, complexity of the transmitter, and limited spurious emissions. Description of Digital Modulation Techniques GSM is a digital system, so speech which is inherently analog, has to be digitized. The method employed by ISDN, and by current telephone systems for multiplexing voice lines over high speed trunks and optical fiber lines, is Pulse Coded Modulation (PCM). The output stream from PCM is 64 kbps, too high a rate to be feasible over a radio link. The 64 kbps signal, although simple to implement, contains much redundancy. The GSM group studied several speech coding algorithms on the basis of subjective speech quality and complexity (which is related to cost, processing delay, and power consumption once implemented) before arriving at the choice of a Regular Pulse Excited -- Linear Predictive Coder (RPE--LPC) with a Long Term Predictor loop. Basically, information from previous samples, which does not change very quickly, is used to predict the current sample. The coefficients of the linear combination of the previous samples, plus an encoded form of the residual, the difference between the predicted and actual sample, represent the signal. Speech is divided into 20 millisecond samples, each of which is encoded as 260 bits, giving a total bit rate of 13 kbps. This is the so-called Full-Rate speech coding. Recently, an Enhanced Full-Rate (EFR) speech coding algorithm has been implemented by some North American GSM1900 operators. This is said to provide improved speech quality using the existing 13 kbps bit rate. Because of natural and man-made electromagnetic interference, the encoded speech or data signal transmitted over the radio interface must be protected from errors. GSM uses convolutional encoding and block interleaving to achieve this protection. The exact algorithms used differ for speech and for different data rates. The method used for speech blocks will be described below. MU203 SECRET Page4,Total 6 Recall that the speech codec produces a 260 bit block for every 20 ms speech sample. From subjective testing, it was found that some bits of this block were more important for perceived speech quality than others. The bits are thus divided into three classes: Class Ia 50 bits - most sensitive to bit errors Class Ib 132 bits - moderately sensitive to bit errors Class II 78 bits - least sensitive to bit errors Class Ia bits have a 3 bit Cyclic Redundancy Code added for error detection. If an error is detected, the frame is judged too damaged to be comprehensible and it is discarded. It is replaced by a slightly attenuated version of the previous correctly received frame. These 53 bits, together with the 132 Class Ib bits and a 4 bit tail sequence (a total of 189 bits), are input into a 1/2 rate convolutional encoder of constraint length 4. Each input bit is encoded as two output bits, based on a combination of the previous 4 input bits. The convolutional encoder thus outputs 378 bits, to which are added the 78 remaining Class II bits, which are unprotected. Thus every 20 ms speech sample is encoded as 456 bits, giving a bit rate of 22.8 kbps. To further protect against the burst errors common to the radio interface, each sample is interleaved. The 456 bits output by the convolutional encoder are divided into 8 blocks of 57 bits, and these blocks are transmitted in eight consecutive time-slot bursts. Since each time-slot burst can carry two 57 bit blocks, each burst carries traffic from two different speech samples. Recall that each time-slot burst is t…

MU203 Electromagnetic Radiation Exposure Estimation 1 Maximum Permissible Exposure (MPE) Estimation for MU203 1 Introduction MU203 WCDMA/EDGE/GPRS/GSM dual mode 6 bands Wireless Module is subscriber equipment in the UMTS/GSM system. The WCDMA frequency is Band I, and Band VIII. The GSM/GPRS/EDGE frequency bands include GSM850, EGSM900, DCS1800 and PCS1900. MU203 implement such functions as Rsignal receiving/transmitting, WCDMA and EDGE/GPRS/GSM protocol processing, data service etc. Externally it provides BTB interface (to connect to the notebook etc.) 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 ) MU203 Electromagnetic Radiation Exposure Estimation 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 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 MU203 Electromagnetic Radiation Exposure Estimation 3 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. 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 MU203 Technical Specification: Cellular Band Power at antenna connector BTS: 31.71 dBm (GSM850) Antenna-cable attenuation: 0 dB Input power to antenna: 31.71 dBm（1.48W）(GSM850) Antenna gain: 4.28 dBi (2.68) MU203 Electromagnetic Radiation Exposure Estimation 4 PCS Band Power at antenna connector BTS: 30.48 dBm (PCS1900) Antenna-cable attenuation: 0 dB Input power to antenna: 30.48 dBm （1.12W）(PCS1900) Antenna gain: 2.1 dBi (1.62) 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*1480 S =0.099 mW/cm 2 For GPRS and EDGE, t…
