Section 15.247(e): Processing Gain Test Method The test method attach in the docket 97-114 appendix C Jamming Test setup that we found there were couple disadvantage as list in the follow: (1) It can not simulate the real world condition (2) Most of the hand held device (include notebook computer ) there is no ground connection to the earth, especially the RF front end ground. (3) The Coaxial and internal RF module will leak the signal that even you connect very high value attenuator .(shielding effective is low in the 2.4 GHz) (4) There was very high uncertainty of measurement result and it is depended how you connect EUT, testing facility, wire and cable for BER measurement, power supply... all of this can affect the testing result. (5) Move out the antenna is inconvenient for the testing and need more sample. Base on the above reason we modify the original jamming test setup figure 1,and use two fully anechoic chambers to isolate test EUT and reference EUT. Test procedure is simulated normal jamming setup, the block diagram as below.

Compliance to this requirement can be shown by demonstrating a relative bit-error-ratio (BER) performance improvement (and corresponding signal to noise ratio per symbol improvement of at least 10dB )between the case where spread spectrum processes (coding, modulation) are engaged relative to the processes being bypassed. In some practical system, the spread spectrum processing cannot simply bypassed. In accordance with the new NPRM 99-231, if the vendor has a system with less than 10 chips per symbol, the CW jamming results must be supported by a theoretical explanation of the system processing gain. (2) Theoretical calculations The processing gain is related to the jamming margin as follows: system output p L S J N S +       +       =G Where REFERENCE BER is the reference bit error ratio with its corresponding, theoretical output signal to noise ratio per symbol,() outputN S ,() S J is the jamming margin (jamming signal power relative to desired signal power),and system L are the system implementation losses. The maximum allowed total system implementation loss is 2 dB. The HFA3861A direct sequence spread spectrum baseband processor uses CCK modulation, which is a form of M-ray Orthogonal Keying. The BER performance curve is given by: The probability of error for generalized M-ary Orthogonal signaling using coherent demodulation is given by: dz Z E zQP N S M b ce       −                         +−−=−= ∫ ∞ − − 2 exp212 2 1 11P 2 1 2 1 0 01 η π This integral cannot be solved in closed form, and numerical integration must be used. This is done in a MATHCAD environment and is displayed in graphical format The reference PER is specified as 8% . When operating DOPSK at 2Mbps, the corresponding Es/No (signal to noise ratio per symbol) is 13.3 dB. The Es/No required to achieve the desired BER with maximum system implementation losses is 15.3dB. The minimum processing gain is again, 10dB, therefore: dB S J dBdBL S J N E system output o s p 100.24.16G≥       ++=+       +         = dB S J dBG p 104.18≥       += The minimum jammer to signal ratio is as follow: dB4.8 S J −≥       =13.3dB =15.3dB Test Procedure The test block diagram be shown figure (). (1) Install DOS Test toll into two notebook computers (E.U.T. and Reference) (2) Set the Reference notebook computer as DBPSK and the E.U.T. notebook computer as DBPSK. And both is link. (3) The signal generator RF output is disabled. (4) Generated the Log File in the Reference notebook computer and send the test file. And measure the power at the power meter port using the power meter (PM1). This is the relative signal power, S (5) Ensure that CW Jammer generator RF out put is disabled and measure the power at the power meter port using the power meter (PM2). This is the relative signal power, J. (6) Set CW Jammer generator RF output frequency equal to the carrier frequency and enable generator output Set reference CW Jammer power level at power meter port 8.4 dB below r S (minimum J/S, or 10 dB processing gain reference level).Note the power level setting on the generator, this is the reference CW Jammer power setting, r J(PM2). (7) Disable CW Jammer generator, re-establish link. PER test should be operating essentially error-free. (8) Enable CW Jammer at the reference power level and verify that the PER test indicates a PER of less than 8%. (9) Alternatively, adjust the CW Jammer level to that which causes 8% PER and verify that the S/J is less than 8.4dB. (10) Repeat step 8 for uniform steps in frequency increments of 50kHz across the receiver passband with the CW Jammer. In this case the receiver passband is 5.0MHz. The number of points where the PER fail to achieve 8% (is higher than 8%) is determined and if this is above 20% of the total, the test is failed otherwise it is passed. The margin by which the radio passes the test (for information purposes) can be determined from the average of the remaining points’ PERs scaled on the PER curve above. 7.5 Test Result of Processing Gain Table 1 Processing Gain [Channel 6, DQPSK, 2.43205GHz to 2.43405GHz] Jammer Frequency (MHz) Signal Level S (dBm)…

RF SAFETY MPE calculation for this Wall mounted Mobile device (at 20 cm) According to OET BULLETIN 56 Fourth Edition/August 1999, Equation for Predicting RF Fields: = 0.00878839 mW/cm 2 Where: S = power density (in appropriate units, e.g. mW/cm2) 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) S = PG 4R 2 S = 31.33x1.41 4 2

Section 15.247(e): Processing Gain Test Method The expected BWE versus Eb/N0 curves for these cases may be determined as follow. Differential error extension The modulation is either DBPSK or DQPSK for 1 and 2 Mbps. With differential coding, there is an error extension factor of 2 which comes from the fact that if one symbol is in error , then the next will be demodulated in error too since it’s phase is dependent on the change of phase from symbol to symbol. In DBSSK, this results in a simple factor of two in BER. With QDQPSK, the picture is a little muddied in that a symbol error may cause one or two bit error since two bits are carried per symbol. The IEEE 802.11 modulations use Grey coding of the phase so that usually only one bit error occurs with a symbol error. Sometimes, two bit errors occur, but this is infrequent at the BER considered. This will be shown to be important in descrambling. What we see when running the BER test is that the errors generally occur in groups of 6 with occasional 4s. The overall effect is to move where we operate on the BER curve. The curve below shows the resulting BER versus Eb/No curve. It is well known that a simple BPSK link operates at 9.6 dB for le-5 BER. With the error extension effect, we see that at that Eb/N0, the error rate is 6 e-5. Or, conversely, we must operate at 10.3dB to get 1e-5. When operating DQPSK at 2Mbps, the Eb/N0 remains essentially the same , but the Es/N0 goes up by 3 dB. For the purposes of the FCC testing for CW jamming , we add the allowed 2 dB for implementation loss to get a net Db/N0 of 15.3 dB.
