FCC STATEMENT (FOR USA ONLY) FEDERAL COMMUNICATIONS COMMISSION Radio Frequency Interference Statement for Spread Spectrum Devices Warning: This equipment generates, uses, and can radiate radio frequency energy. If it is not installed and used in accordance with the instruction manual, it may cause interference to radio communications. It has been tested and found to comply with the limits for a Class A computing device pursuant to Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area will probably cause interference, in which case the user at his own expense will be required to take whatever measures may be required to correct the interference. Electronic Emission Notices All the spread spectrum devices sold in this catalog comply 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. If this equipment causes interference to radio reception (which can be determined by unplugging the power cord from the equipment) try these measures: (1) Re-orient the receiving antenna, (2) Relocate the equipment with respect to the receiver, (3) Plug the equipment and receiver into different branch circuits, or (4) Consult your dealer or an experienced technician for additional suggestions. DANGER!!! Rooftop or tower antenna installations are extremely dangerous and incorrect installation may result in injury, damage, or death. Rooftop and tower installations must be performed by professional antenna installers only. WARNING! This is a 2.4 GHz point-to-point system. The conducted output is 36mW with Gant = 24 dBi. This system is used exclusively for fixed point-to-point operations. It is prohibited to transmit the same information from multiple co-located antennas. This equipment must be professionally installed. In order to comply with FCC RF Exposure requirements, this device must be installed in such that a minimum separation distance of 1 meter (3.5’) is always maintained between the antenna and all persons. The operator and professional inst…

The photos of the amplifier should reflect this information. It is possible that they sent a generic schematic as they make amplifiers in this case style with different gains. I also believe the 1 Watt rating is for a CW or narrowband signal and not a wideband signal. The owners manual stating 38 mW is the generic users manual for Speedcom and should have been updated for this particular product to reflect the 88 mW power (an oversight on the publications person). The 38 mW rating is for a previous model unit without an amplifier. The manual to be included with this model unit will have the 88 mW power listed. All measurements were carried out with this power amplifier operating in the system and at the antenna connector. Best Regards, Mario R. de Aranzeta Engineer

Shielded interface cables were used in all cases except for cables connecting to the telephone line and the power cords. A test program was run which simulated a normal data transmission on a network. POWER LINE CONDUCTED INTERFERENCE: The procedure used was ANSI STAN- DARD C63.4-1992 using a 50uH LISN. Both lines were observed with the UUT transmitting. The bandwidth of the spectrum analyzer was 10kHz with an appropriate sweep speed. The ambient temperature of the UUT was 76oF with a humidity of 55%. BANDWIDTH 6.0dB: The measurements were made with the spectrum analyz- er's resolution bandwidth(RBW)=1.0MHz and the video bandwidth(VBW) =3.0MHz and the span set as shown on plot. POWER OUTPUT: The RF power output was measured at the antenna feed point using a peak power meter. ANTENNA CONDUCTED EMISSIONS: The RBW=100KHz, VBW=300KHz and the span set to 10.0MHz and the spectrum was scanned from 30MHz to the 10th Harmonic of the fundamental. Above 1.0GHz the resolution bandwidth was 1.0MHz and the VBW = 3.0MHz and the span to 50MHz. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a prese- lector. The bandwidth(RBW) of the spectrum analyzer was 100kHz up to 1GHz and 1.0MHz above 1GHz with an appropriate sweep speed. The VBW above 1.0GHz was = 3.0MHz. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The ambient temperature of the UUT was 71oF with a humidity of 56%. APPLICANT: SPEEDCOM WIRELESS INTERNATIONAL CORP.

Lucent WCND Confidential ©1999 This document describes the Receiver Processing Gain verification measurements performed at the WaveLAN-II PC-Card Type 2, according to Ref.[2]. The Lucent WaveLAN-II PC-Card Type 2 product confirms to the minimum required 10 dB processing gain, as set forth by the FCC for operation in the 2.4 GHz ISM band. 1- Document FCC 97-114, Appendix C, Guidance on Measurements for Direct Sequence Spread Spectrum Systems. 2- Hardware Functional Specification for WaveLAN-II Embedded, High Speed, Doc.

This test proves that the receiver of the tested product employs a true spread spectrum device receiver structure, taking full advantage of the direct sequence spread spectrum modulation technique. This test verifies the receiver processing gain to be 10 dB or more for a data rate of 1, 2, 5.5 and 11 Mbit/s, by monitoring the Bit Error Rate (BER) of the product under test for each data rate, while operating under strict defined received signal conditions. Several methods of showing compliance to the rules are possible, from a stepped CW jammer to a continuous sweeping CW interferer. For this test the discrete stepped CW jammer method was chosen, as described in Ref.[1]. 1.Summary: 2.Conclusion: 3.References: 4.Measurement description: FCC Processing Gain Measurements Results, FCCID WLPC24H/WLPCE24H, Report No. 011734, Rev. B. Lucent WCND Confidential ©1999 Therefore a receiver input signal is applied to the product under test, in the presence of a Continuous Wave (CW) interference source, also referred to as CW jammer. The test takes place at the product Functional Specification (Ref.[2]) specified conditions for BER rate measurements, specifying a BER equal or better than 10^-8 at a receiver input level of -55 dBm. For practical reasons these test are performed at -55 dBm or -53 dBm. This small deviation from the Functional Specification should not cause any deviation from the specified Bit Error Rate, since the received levels are well above the thermal noise. The test criteria for meeting the minimal processing gain is such that it takes the theoretical calculated SNR for the applied modulation technique and specified BER as a reference. From this given SNR the processing gain is subtracted, yielding the CW Jammer to Signal ratio J/S. From Ref. [4], likewise as Ref.[3] consulted in Ref. [1], it is determined that for a BER of 10^-8 the SNR (S/N)o equals: 13 dB @ 1 Mbit/s, 15 dB @ 2 Mbit/s, 15 dB @ 5.5 Mbit/s, 18 dB @ 11 Mbit/s. Thus the J/S ratio for a processing gain of 10 dB that must be met is calculated as: -13 + 10 = -3 dB @ 1 Mbit/s (DBPSK), -15 + 10 = -5 dB @ 2 Mbit/s (DQPSK), -15 + 10 = -5 dB @ 5.5 Mbit/s (CCK), -18 + 10 = -8 dB @ 11 Mbit/s (CCK). Two types of measurement corrections are allowed for as described in Ref.[1]. The first taking into account 2 dB implementation losses, thus increasing the absolute J/S ratio by 2 dB. The second correction allows for deleting the 20% worst- case frequencies in the processing gain test that causes the test at that CW interference to fail. This implies that for the considered 14 MHz wide measurement interval the worst case 57 CW jammer frequencies can be ignored, being those that result in FCC Processing Gain Measurements Results, FCCID WLPC24H/WLPCE24H, Report No. 011734, Rev. B. Lucent WCND Confidential ©1999 received data errors/missing frames (20% of 14 MHz *(1 MHz/50 KHz) + 1 = (20% * 281) + 1 = 57). FCC Processing Gain Measurements Results, FCCID WLPC24H/WLPCE24H, Report No. 011734, Rev. B. Lucent WCND Confidential ©1999 4.2 Test sequence: The measurements are performed at a 50 KHz CW jammer raster. For each CW jammer frequency 10^8 bits are transmitted by the reference transmitter, and received by the product under test. For practical reasons 50.000 messages are transmitted. After blanking out frame overhead 1927 bits per frame are monitored. This results in 50.000 * 1927 = 9650000 transmitted bits for a BER test, which is a mere 1.4% less than the targeted 10^8 bits. Though it would be more elegant to show BER compliance for at least say ten times 10^8 transmitted/received bits, the time involved with this grows significantly. Since the CW interferer is stepped in a 50 KHz raster, covering the re…
