APCD-LM043-5.0-D191 Appendix G Antenna Guidelines WARNING! Antennas and associated transmission cable must be installed by qualified personnel, and external antennas must be properly grounded. Incorrect termination of the antenna port can permanently damage the EUM. WaveRider assumes no liability for failure to adhere to this recommendation or to recognized general safety precautions. The CCU and EUM have been certified for use with Omni, Patch, Yagi, and Dipole Reflector antenna types, in addition to the WaveRider Diversity Antenna.Ta b l e 5 5includes examples of each of the recommended antenna types, as well as their associated maximum antenna gains. Table 55 CCU, EUM Supported Antennas Antenna system gain is the net gain of the system. In other words, it is the antenna gain minus the insertion loss due to cabling, connectors, filters, surge protectors, and other hardware components. During installation, you must verify that the antenna system does not exceed the maximum allowable certified antenna system gain, which is 8.8 dBi. Calculate the antenna system gain by adding the value of the insertion loss for each component of the antenna system, excluding the antenna, and subtracting the total of that sum from the antenna gain. You can measure the insertion loss of the components, and the Antenna TypeMaximum Antenna Gain Omni5.1dBi Patch8.5 dBi Yagi13.0dBi Panel12.0dBi 192APCD-LM043-5.0-D antenna gain, at the frequency of interest, or obtain it by referencing the manufacturer’s supplied literature. WaveRider Guidelines for outdoor installation are: •select a cable of type and length so that cable loss is 3.5dB, including connectors. •use a surge protector, which has about 0.1 db loss, •use a WaveRider jumper cable to connect the modem to the exterior cable or surge protector. The jumper cable has a loss of 1 dB. For example, with a Yagi antenna system, 15 m of cable, a surge protector, and a jumper cable (from modem to surge protector), you would calculate the following antenna system gain: •Antenna Gain: 13.0 dBi •Insertion loss: •External Cable:- 3.5 dB •Surge Protector:- 0.1dB •Jumper Cable:- 1.0 dB •-4.6dBi The antenna gain (13.0 dBi) minus the total insertion loss (4.6 dBi), yields an antenna system gain of 8.4 dBi, which is a valid antenna configuration, because the antenna system gain is lower than the maximum permissible value of 8.8 dBi. WARNING! To prevent equipment damage, you must use the WaveRider proprietary WCM connector to connect transmission line and antennas to the EUM3000. WARNING! Use of an outdoor antenna with the EUM requires professional installation, in accordance with FCC guidelines. WARNING! Antennas used with the EUM must not present a short to ground at the EUM antenna port. Contact the WaveRider Customer Support Centre for more information.

It is a single PCB wireless solution based on the Intersil PRISM II Direct Sequence Chip Set. The EUM3003 is functionally equivalent to the EUM3000 (previously certified with FCC ID: OOX-LMS3000) in regards to frequency of operation, output power, and modulation scheme. The main difference from the user’s perspective is that RS232 and USB interfaces are not available on the EUM3003. Changes to the RF synthesizer in the radio circuitry of the EUM3003 require that it be resubmitted for certification. Overall functionality The two block diagrams, one representing the RF functionality, the other the Digital functionality of the radio module are located in Figures 1 and 2. The digital section contains the following functionality: 1. I/O 2. Ethernet Controller 3. Microprocessor 4. MAC 5. Memory 6. Reference Oscillator 7. Power Regulation The radio module’s RF section contains the following functionality: 1. Baseband Processor 2. Modulator/Demodulator (with IF synthesizer) 3. RF Synthesizer 4. Up Converter 5. Power Amplifier 6. Low Noise Amplifier (LNA) 7. Down Converter 8. RF VCO 9. IF VCO 10. 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 using CCK modulation and then spread using a defined PN code such that the data is sent at a rate of 2.75Mbit/s. The data is preceded by a header that uses DPSK modulation. 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 and used to modulate the I & Q signals. The final IF signal of 70 MHz is then sent to the Up converter. The Up converter will shift this signal to the RF frequency for the channel programmed in the synthesizer, for operation within the 902-928 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. Page 2Printed: 12/30/02 11:35 AM Murandi Communications Ltd. Suite 300, 6715 - 8th St. NE, Calgary, Alberta, Canada, T2E 7H7 Tel: (403) 777-9988Fax: (403) 777-9989 In receive mode, the radio signal is amplified by the LNA, and then sent to the Down converter. The Down converter converts this signal from the 902-928 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 synthesizers and voltage controlled oscillators. The RF synthesizer is programmed with the desired RF channel frequency plus the IF frequency. The IF synthesizer in the Modulator/Demodulator is programmed with 140MHz. 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 Antennas The antenna (RF) connector is a non-standard wide-barrel SMA connector and is connected to one of two antenna configurations: 1) A diversity antenna 2) A Yagi, Panel, or Patch antenna through a 50-ohm impedance matched transmission line (Times Microwave LMR-200) The unit was qualified with 4 different antennas types; Yagi, Panel, Patch and Diversity. For output powers of 26dBm, the antenna system gains shall be 10 dBi or less in order to meet the regulatory requirements of 15.247(b)(4). However, to meet power density requirements of 1.1310, the antenna system gain is limited to 8.8dBi. The following table shows antenna gains for each type of antenna and the associated antenna system gain including cable losses for typical installations. AntennaCableAnt.

Calculating for the lowest frequency of operation (905MHz), the maximum power density allowed is 0.603 mW/cm 2 . The power density is calculated as follows: S = (P*G)/(4*pi*R 2 ) where: S = power density in mW/cm 2 P = power at the antenna connector in mW G = linear system gain of the antenna R = separation from antenna (cm) As per the User’s manual, all antennas for the EUM (indoor and outdoor) must be fix-mounted such that there is at least 20cm of separation between the antenna and a person. For an output power of 26dBm (398mW), and a separation of 20cm, the maximum allowable antenna system gain is 8.8dBi. The antenna system gain for all antenna types shown in “EUM3003 Functional Overview” are less than the limit of 8.8dBi, therefore meeting the FCC requirements for human exposure to RF radiation.
