The EUT provides wireless communications between computers. The EUT is designed to be installed into the PCMCIA slot of a notebook computer or desktop computer with a PCMCIA slot. The EUT communicates with other wireless LAN cards using the frequency range from 2.412 GHz to 2.460 GHz. The EUT is powered from the PCMCIA slot, and does not have an external power supply. The EUT uses an external PCB antenna. The EUT uses 2- bits encoded to 4 complex code words; 2-DQPSK CCK modulation technique with 8 Chips per symbol, spread clock rate is 1.375 MHz symbol/sec, and the data rate = 11 MBPS.

The Electric field generated for a 1mW/cm 2 exposure (S) is calculated as follows: S = E 2 /Z where: S = Power density E = Electric field Z = Impedance. E = √S x Z 1mW/cm 2 = 10 W/m 2 The impedance of free space is 337 ohms, where E and H fields are perpendicular. Thus: E = √10 x 377 = 61.4 V/m which is equivalent to 1mW/cm 2 Using the relationship between Electric field E, Power in watts P, and distance in meters d, the corresponding Antenna numeric gain G and the transmitter output power and solving for d, d = √ P eak x 30 x G E 1. The Numeric gain G of antenna with a gain specified in dB is determined by: G = Log –1 (dB gain/10) G = Log –1 2.15 = 1.64 Notice in Installation Manual: While installing and operating this transmitter and antenna combination the radio frequency exposure limit of 1mW/cm 2 may be exceeded at distances close to the antennas installed. Therefore, the user must maintain a minimum distance of 20 cm from the antenna at all time.

INSTALLATION MANUAL Introduction This manual does not substitute your wireless LAN card’s user’s guide. This installation guide must be read for more detailed information about your wireless LAN card’s use, care and maintenance, including important safety information. The Samsung Wireless LAN Card has two antenna connectors for attaching external antennas for coverage area extension. Use only the supplied antenna. Unauthorized antennas, modifications, or attachments could damage the wireless LAN card and may violate regulations governing radio devices. FCC WARNING The SWL-2000E complies with Part 15 of the FCC rules. Operation is subject to the following two conditions; (1) This device may not cause harmful interference. (2) This device must accept any interference received, including interference that may cause undesired operation. RF SAFETY WARNING While installing and operating this transmitter and antenna combination the radio frequency exposure limit of 1mW/cm 2 may be exceeded at distances close to the antennas installed. Therefore, the user must maintain a minimum distance of 20 cm from the antenna. Note: The SWL-2000E has been tested and found to comply with the limits for a Class B digital device and a low power transmitter, according to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to resolve the problem by one or more of the following measures; Reorient or relocate the receiving antenna. Increase the separation between the equipment and the receiver. Connect the equipment to an output on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. INSTALLATION OF THE EXTERNAL ANTENNA The user is responsible for ensuring that the public is not exposed to radio frequency energy levels in excess of the FCC guidelines. Humans cannot be within 20 cm (8 inches) of the front of the antennas. If such a situation occurs, the user is responsible for placing the appropriate caution signs to warn the public. Notebook PC Adapter Card (SWL-2000E) • You can install the card whether the power of the Notebook is on or off. • Insert the SWL-2000E adapter card into the PCMCIA slot. (A pleasant “cheep” sound indicates the regular operation. A low monotonous tone indicates a failure in recognition.). Always maintain a 20cm space between your self, any other person and the antenna. Warning: The antenna should be mounted so that the main beam is not pointing towards areas of heavy human traffic. If you see red Power LED illuminating and green Rx LED is blinking, you are now ready to proceed to software setup. STUB ANTENNA

Measurement of Processing Gain of a Direct Sequence Spread Spectrum System Certification Report on Compliance with Respect to FCC CFR 47, Paragraph 15.247(e) Product: Samsung SWL-2000E Wireless LAN Card August 17, 2000 REPORT PREPARED BY: Rick McMurray Rhein Tech Laboratories, Inc. 360 Herndon Parkway, Suite 1400 Herndon, VA 20170 (703) 689-0368 (703) 689-2056 fax Rhein Tech Laboratories, Inc. Scope This report contains the results of the processing gain testing performed on the Samsung SWL- 2000E Wireless LAN Cards. The tests were carried out in accordance with FCC CFR 47, Paragraph 15.247(e). The jamming margin method specified in 15.247(e)(2) was used to perform the processing gain testing. FCC 97-114, Guidance on Measurements for Direct Sequence Spread Spectrum Systems, was also utilized as a guiding document for the performance of the processing gain testing. FCC Requirements The processing gain of a direct sequence system shall be at least 10dB. 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 output of the receiver. Test Equipment Hewlett Packard Spectrum Analyzer, Model 8564E (RTL Asset # 901020) Hewlett Packard Signal Generator, Model 8648C, 100kHz-3200MHz (RTL Asset # 900917) Weinschel Broadband Resistive Power Divider, Model 1515, DC to 18.0GHz 1 Watt Weinschel Directional Coupler, Model 1537RA-20, 0.5 to 4.0GHz IBM ThinkPad Laptop computers used with transmitter and receiver Equipment Under Test Transmitter: Samsung SWL-2000E, MagicLAN Wireless LAN Card Marked #2, R and D sample #10, LEKRDAA05A5C09, Intersil Prism on Board Receiver: Samsung SWL-2000E, MagicLAN Wireless LAN Card Marked #1, R and D sample #11, LEKRDAA05A5C00, Intersil Prism on Board Method of Measurement As mentioned in the scope section, the jamming margin method was used. The following drawing titled “Processing Gain – Jamming Test Setup” illustrates a block diagram of the test setup. In this method, a signal generator was stepped in 50kHz increments across the passband of the system. At each point, the level of the signal generator required to produce the recommended Bit Error Rate (BER) was recorded. This level is the jammer level. The output power of the transmitter was also recorded at these same points. This level is the signal level. The jammer to signal ratio (J/S) was then calculated. The worst 20% of the J/S data points were discarded. The lowest remaining J/S ratio was used to calculate the processing gain for each of the channels investigated. The processing gain, Gp, was calculated as follows: Gp = (S/N)o + Mj + Lsys, where Gp = the processing gain of the system, (S/N)o = signal to noise ratio required Rhein Tech Laboratories, Inc. for the chosen BER, Mj = J/S ratio, and Lsys = system losses. Note that total system losses in a system, including intentional radiator and receiver, are assumed to be no more than 2dB as specified by the FCC. An ideal signal to noise ratio, also referred to as (S/N)o or (Es/No), of 16.4dB was used as specified by Intersil when calculating the processing gain when operating at 11Mbps. The Samsung SWL-2000E contains chip-sets from Intersil and operates at 11Mbps. Please see the enclosed document “Testing for compliance with FCC rules 15-247e” by Carl Andren of Intersil Corporation for more information. The use of 8% FER frame error rate (or PER packet error rate) as a substitute for the recommended BER bit error rate is derived in the attached document “Testing for compliance with FCC rules 15-247e” by Carl Andren of Intersil Corporation.
