LMS-3000 Functional Overview The LMS-3000 radio module is a single PCB wireless solution based on the Intersil PRISM II Direct Sequence Chip Set. The two block diagrams, one representing the RF functionality , the other the Digital functionality of the radio module are located in Figure 1 and 2. The digital section contains the following functionality: 1) I/O 2) Microprocessor 3) MAC 4) Memory 5) Reference Oscillator 6) Power Regulation The radio modules RF section contains the following functionality: 1. Baseband Processor 2. Modulator/Demodulator 3. Dual Synthesizer 4. Up/Down Converter 5. Power Amplifier 6. Low Noise Amplifier (LNA) 7. RF VCO 8. IF VCO 9. Antenna (RF) Interface During transmission , data obtained by the Microprocessor from the I/O ports, is transferred to the MAC. The MAC reformats the data and places it on the Baseband Processor TX data line. This data is modulated according to the format selected (CCK) and then spread using a defined PN code. Two signals are generated (the In-Phase (I) and Quadrature (Q) components). The I & Q signals are sent to the Modulator/Demodulator where they are first filtered and then modulated with the IF frequency (70 MHz). The IF oscillator generates a 140 MHz signal which is divided by two inside the Modulator/Demodulator, generating a final IF signal of 70 MHz. Next, the two signals are combined into a single signal and sent to the Up/Down converter. The Up/Down converter will shift this signal to the RF frequency for the channel programmed in the synthesizer, for operation within the 902-28 MHz ISM band. In the final stage, this signal is amplified to produce +26 dBm RF power output as measured at the output of the antenna port. In the receive mode, the radio signal is amplified by the LNA, and then sent to the Up/Down converter. The Up/Down converter down-converts this signal from the 902-28 MHz range to the IF frequency, 70 MHz. The Modulator/Demodulator then converts the signal to baseband and splits the signal into its I & Q components, before sending it to the Baseband Processor. Finally, the Baseband Processor despreads and demodulates the data contained in the CCK format, and places it on the RX data line to the MAC. The MAC modifies the data, then transfers it to the Microprocessor which reformats the information and sends it out the I/O ports. The RF and IF Local Oscillator signals are generated using the synthesizer and voltage controlled oscillators. The synthesizer is programmed with the desired RF channel frequency plus the IF frequency. The baseband processor and the synthesizer are driven from a common 44 MHz oscillator to control the timing of these chips. Example (for Channel 1 operation) : RF IF LO 905 MHz + 70 MHz = 975 MHz The antenna (RF) connector is connected to a 50-ohm impedance matched transmission line (Times Microwave LMR-400 or LMR-600) to one of the following antenna types: Omni, Disc, Patch, Yagi and Dipole Reflector.

1. Radio Frequency exposure 1.1 Regulation 15.247(b4) Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission’s guidelines. See §1.1307(b)(1) of this Chapter. 1.2 Result According to par 1.1307b(1), the EUT does not require an environmental evaluation. 1. This equipment classification is not present within table 1 of part 1.1307 and is not listed in section 1.1307b(2). 2. The EUT categorically exempt from routine environmental evaluation per section 2.1093. Included are calculations that determine that minimum distance I from the transmitter antenna that will ensure an exposure limit at or below the guidelines given in table 1 of part 1.1310 for the general population. The formula for these calculations are taken from OET Bulletin 65, edition 97-01, August 1997; “Evaluating Compliance with FCC Guidelines for Human Exposure to Radio frequency Electromagnetic Fields”. 1.3 CALCULATIONS Per Table 1 of Section 1.1310 the limit for general population exposure at 2.4 GHz is 1.0 mW/cm 2 Per OET Bulletin 65, edition 97-01 the formula for calculating power density is: S = P*G/4πR 2 with Power = 25.6 dBm = 363 mW Gain of Antenna: System = 10.4 dBi or a numeric gain of 11 therefore Solving for R gives a minimum safe distance of 17.8 cm 1.4 CONCLUSION Page 19 of the user manual instructs the installer to maintain at least a 2 meter separation between personal and the user.

Proakis, McGraw-Hill Book Company 1989 4 Test Background and Procedure. According to FCC regulations [1], a direct sequence spread spectrum system must have a processing gain, G p of at least 10 dB. Compliance to this requirement can be shown by demonstrating a relative bit-error-rate (BER) performance improvement (and corresponding signal to noise ratio per symbol improvement of at least 10 dB) between the case where spread spectrum processes (coding, modulation) are engaged relative to the processes being bypassed. In some practical systems, the spread spectrum processing cannot simply be bypassed. In these cases, the processing gain can be indirectly measured by a jamming margin test [2]. 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. 5 Theoretical calculations The processing gain is related to the jamming margin as follows [2]: system output p L S J N S G +       +       = Where (S/N) output is the theoretical output signal to noise for the desired BER REFERENCE (10 -4 ), (J/S) is the jamming margin (jamming signal power relative to desired signal power), and L system are the system implementation losses. The maximum allowed total system implementation loss is 2 dB. The HFA3861 direct sequence spread spectrum baseband processor uses CCK modulation which is a form of M-ary Orthogonal Keying. The BER performance curve is given by Figure 15 of reference 3, and shown below: Page 4Printed: 05/02/01 9:21 PM Murandi Communications Ltd.
