The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with LG’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. Modifying the equipment without LG’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense. You can determine whether your equipment is causing interference by turning it off. If the interference stops, the LG equipment or one of its peripheral devices probably caused it. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures: • Turn the television or radio antenna until the interference stops. • Move the equipment to one side or the other of the television or radio. • Move the equipment farther away from the television or radio. • Plug the equipment into an outlet that is on a different circuit from the television or radio.

LG GoldStream Page 5 of 39 Chapter 1 Introduction To The Wireless LAN A wireless LAN (WLAN) is a flexible data communication system implemented as an extension to, or as an alternative for, a wired LAN within a building or campus. Using electromagnetic waves, WLANs transmit and receive data over the air, minimizing the need for wired connections. Thus, WLANs combine data connectivity with user mobility, and, through simplified configuration, enable movable LANs. WLANs have gained strong popularity in a number of vertical markets, including the health-care, retail, manufacturing, warehousing, and academic arenas. These industries have profited from the productivity gains of using hand-held terminals and notebook computers to transmit real-time information to centr…

Introduction This paper describes the GoldStream PCI Card 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. LG GoldStream 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 to meet the 802.11 spectral mask specification. Therefore, the output power ne…

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 PCI card using spread spectrum technique for wireless access of a PC to a LAN.. Due to the construction of the PCI card and the position of the antenna at the rear of a desktop or tower/Mini- tower computer, which give 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.
