Page 1 of 1 Statement RF exposure The statements regarding the RF safety information (see file RF_exposure_Ant.doc) will be included in the final version of the manual. Explanation for using a test setup without the enclosure. In order to set the radio in the relevant test modes it was necessary to have access to the radio via a computer. Since it was a pure plastic enclosure, which has no influence to the electrical and electromagnetic performance, it was kept open during the test. Precautions were done to ensure that the worst-case conditions were measured. Lothar Schmidt Technical Manager EMC / Radio

Introduction This paper describes the LG AP circuits, specifications,layouts and partlist etc. 2. Circuit Description 2.1 The Architecture The radio design is centered on the expected signal characteristics of the modulation method. A Differential Quadrature Phase Shift Keying (DQPSK) modulation encodes the data in terms of phase with minimal amplitude variation, improving noise immunity. This is joined with the IEEE 802.11 protocol standard Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) and with the FCC requirement for 10dB processing gain, to allow signals to be received with approximately 0dB Signal to Noise Ratio (SNR) for a 10 -5 Bit Error Rate (BER). The CSMA/CA protocol allows only one user, per channel, at a time (i.e., first come, first serve) making for a quieter medium. The processing gain, achieved by spreading the signal with a PN code, allows a faint signal to be pulled from the noise while suppressing non-correlating interferers. From the antenna, the received input is applied to the pre-select filter FL1. This filter is a two pole dielectric design, rejecting interferers outside the 2.4GHz ISM band and providing image rejection. The signal enters the HFA3683 RF/IF Converter, first passing through the integrated LNA section and then enters the down converter section of the HFA3683. Low-side local oscillator injection is used to mix down to the single intermediate frequency, 374MHz. The IF receive filter FL3, is a Surface Acoustic Wave (SAW) device used for channel selection within the band. The SAW output is reactively matched to the IF input of the HFA3783 Quadrature IF Modulator/Demodulator. In receive mode, the HFA3783 provides two limiting amplifiers, a quadrature baseband demodulator, and two baseband low pass filters. The two limiting amplifiers or limiters provide most of the receiver gain, giving the radio it’s sensitivity. The baseband circuit samples the waveform with 7-bit ADCs and then despreads and demodulates the received data. On the Transmit side, data can either be DBPSK or DQPSK modulated at 1MSPS (Mega Symbols Per Second), resulting in a baseband quadrature signal with I and Q components. These digital signals are output to the HFA3783 fifth order Butterworth low pass filters, which are used to provide shaping of the phase shift keyed (PSK) signal. The required transmit spectral mask, at the antenna, is -30dBc at the first side-lobe relative to the main lobe. The signals are then quadrature modulated up to IF using the same 2xLO used for the quadrature demodulation. The signal then goes to the high impedance input of the HFA3683 upconverting mixer for conversion to the 2.4GHz - 2.5GHz band. The mixer output goes to the pre-amplifier, in the HFA3683, amplifies the signal and easing the requirement for HFA3983 RFPA gain. FL2, a two pole dielectric bandpass filter, is used to suppress both transmit LO leakage and the undesired sideband. The HFA3983 RFPA amplifies the transmit signal to approximately +18dBm. The transmit sidelobe performance is approximately -30dBc. Allowing for a 3dB loss in the band select filter FL1, this gives a final output power of +15dBm. 2.2 Transmit Chain Front End Cascade Analysis The large gain in the Power Amplifier, HFA3983, keeps the signal level small for the whole chain before it. This helps conserve supply current and the cost associated with devices that need to handle large signals. The output power at the RF filter is shown as 15dBm, with the output of the Power Amplifier at 18dBm. The design has been optimized for the best use of supply current and cost of the PA. If the output power was lower, the supply current and cost of the PA could be saved with smaller and cheaper devices. If the output power was higher, the signal will be too close to the P1dB and the signal will have excessive distortion, causing regrowth of the side lobes. The transmitted signal must suppress side lobes to -30dB …

CETECOM Inc. 411 Dixon Landing Road Milpitas, CA 95035 Federal Communication Commission Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 Attention: Reviewing Engineer The LG Electronics Inc. is a regular 802.11b Wireless LAN Access Point using spread spectrum technique for wireless access of a PC to a LAN. Due to the construction and the intended use of the of a LAN access Point, the installation should be done as recommended in the manual in a area free from disturbances and this requires a distance under normal operating conditions of more than 20 cm. This information includes the following : A minimum separation distance of 20 cm must be maintained between the antenna and the person for this device to satisfy the RF exposure requirements of the FCC. The maximum output power for is 100 mW (20 dBm). Maximum EIRP of the equipment = 20 dBm (0.0100 W); equivalent to 8.66 V/m in 10 cm distance Regarding MPE limits, GPUC environment limits maximum exposure to 1 mW/cm 2. The power density is: at 20 centimeters from an antenna S = E 2 /3770=-13 H 2 = 0.01989 mW/cm 2 < 1 mW/ at 10 centimeters from an antenna S = E 2 /3770=-13 H 2 = 0.0795 mW/cm 2 < 1 mW/ Where: S = Power density (mW/cm 2) E = electrical field strength (V/m) Calculations are based on standard formula for calculating field strength at a distance and converting power density using free space impedance. Compliance is shown for the built in module, which have an external the antenna with a unique re ve rse d polarity SMA connector the module even for the distance of 10 cm. This is the distance given by the position of the antenna in the rear of the computer. If you should have any questions regarding this submission, please feel free to contact the undersigned.

Processing Gain of a Direct Sequence Spread Spectrum, FCC CFR 47, Para.15.247(e) Product Name : LW1100AP FCC Requirements: The Processing gain of a direct sequence system shall be at least 10 dB. The Processing gain shall be determined from the ratio in dB of the signal-to-noise ratio with the system spreading code turned off to the signal to noise ratio with the system spreading code turned on, as measured at the demodulated out of the receiver. Environmental Condition: Room temperature and Humidity : +25 °C and 50% Power Input: DC Power from the computer Test Equipment : NOEquipmentsVendorModel NameDescription 1Spectrum AnalyzerAgilentHP8595E9KHz ~ 22 GHz 2Signal GeneratorAgilentE4421A 3Power MeterAgilentHP438A 4Attenuator10 dB, 20 dB 5Step AttenuatorWeinschelAE117A-69-1170 dB 6Step AttenuatorWeinschelAF119A-99-3399 Db 7Power SplitterAceTeq. 8ComputerSamboDreamsys Method of measurement: Jamming Margin Method The processing gain may be measured using the CW jamming method. Figure1 shows the test configuration. The test consists of stepping a signal generator in 50 KHz increments across the passband of the system. At each point, the generator level required to produce the recommended Bit Error Rate(BER) is recorded. This level is the jammer level. The outp…
