This means that the radio can be used in various packages and configurations provided the requirements below are met. These requirements apply to any WaveRider final product using the 915A radio. Note that this radio under the 915A certifications cannot be sold as a bare board to end- customers or OEMs. Only WaveRider manufactured final products can be sold. As such, this document is intended only for WaveRider or its contractors to act as an ‘installation guide’ for installing the 915A radio into a final product. Adhering to these requirements will not necessarily ensure compliance to FCC and IC requirements for the final product. If there are any concerns, testing should be done to ensure compliance. For example, the 915A radio meets the FCC and IC Class B unintentional radiator requirements as a standalone unit. If it is combined with other components or radios, the aggregate may not meet the same limits as the standalone unit. The term “final product” in this document will refer to the product that is sold that incorporates the 915A radio. WaveRider products that use the 915A radio currently includes the EUM2005. This document will be updated as new configurations are approved for the 915A radio, such as new antenna and power supplies. The approved configurations are shown in Section 3. WARNING – Final product (e.g. EUM3005, MMT9000, etc.) user documentation (e.g. Installation Guides, Spec. Sheets) must NOT contain any information about how the 915A radio is installed in the final product nor how to access the radio.

Mr. Gordon, Please address the following issues for this application, 2. Please clarify if the antennas connected to the module were maximized for different polarizations within their range of motion. [LAG] The WaveRider Antenna has a vertical polarization. The diversity is based on switching beam patterns, with the primary beam pattern having the maximum gain along the normal vector to the antenna ground plane. The secondary beam pattern has its maximum peak at about 90 degress horizontal to the primary and is also vertically polarized, but the peak is about 3 dB less than the primary beam pattern. The WaveRider antenna was tested so that it directly faced the test antenna with no up or down tilt so that the test antenna would see the peak antenna gain. The variable elevation of the test antenna and rotation of the test table ensure that any alignment errors are found. [LAG] The YAGI antenna can be physically mounted for either horizontal or vertical polarization. The test lab chose the horizontal polarization so that the maximum gain would be seen on the horizontal orientation of the test antenna and the max. sidelobes of the YAGI beam patterns would be seen doing the test table rotation. Again, any alignment errors would be removed by the test table rotation and test antenna elevation changes. So the short answer is "yes the antennas were maximized for their polarization". [LAG] The following is a statement from our test lab in response to your question: ----------------------------------------- Hello, Lawrence; The EUT yagi antenna was mounted in horizontal polarization on the turntable. This was rotated through 360 degrees to determine the azimuth relative to the receiving antenna that produced the maximum emission at each test frequency. The receiving antenna was scanned from 1 m to 4m in order to find the height at which the received emission was maximum. These maximization searches were performed for both polarizations of the receiving antenna. Please contact me if you have any questions or comments. Regards, David Raynes [email protected] Laboratory Supervisor Electronics Test Centre (Airdrie) [LAG] ------------------------------------------------------------------------- ***********Follow up by TCB to item 2 *************** In your response to item 2, it appears YAGI antenna has been tested in H polarization only. If there will be installations where the installer will make use of the V polarization, the test data does not specifically represent this case. Please clarify how compliance is ensured in case of V polarity. For a YAGI, the E-plane is the plane in which the dipole elements lie and the H plane is the plane at right angles to the E-plane and along the main strut of the YAGI. For the antenna in the horizontal position, as in our test, the E-plane is scanned for a full 360 degrees since it is parallel to the turntable. The H-plane is scanned from -18 degrees (test antenna at 0 (1 meter below height of antenna) to about 45 degrees ( 3 meter elevation over 3 meter distance). This is direct line of sight. As you can see from the spec sheets, the 3 dB beamwidth of a 13 dBi YAGI is 35-40 degrees in the E-plane (i.e. +/- 17 to 20 degrees from the main antenna strut), and 40-45 degrees in the H- plane (i.e. +/- 20 to 23 degrees from the main antenna strut). And as the beam patterns show the biggest sidelobe for a 13 dBi YAGI is at least 12 dB less than the main lobe. From this, I conclude that inspection of the main lobe is representative of the worst case possible for a YAGI antenna and for a high-gain YAGI this main lobe is less than +/- 25 degrees off the main strut line, in both planes. So, the testing of the antenna over 360 degrees of the E-plane and -18 to +45 degrees of the H-plane more than covers the main lobe. Turning the antenna 90 degrees to vertical polarization would swap the E and H planes, but not affect the main lobe geometry. And the main lobe geometry is confirmed by the test report, where all peaks with the Horizontal test antenna are directly in front of the antenna (0, 4 and 360 degrees for 905, 915 and 925 MHz). The Vertical/Horizontal ratio is at least 20 dB as shown by the test report. All peaks (carrier and spurious emissions in restricted bands) were within 30 cm of the antenna height (1 m) or less than 6 degrees. When we tested the same antenna in the vertical position for the EUM3004, all peaks were found by the vertical orientation of the test antenna at 0 degrees azimuth and an antenna height of 100 cm, or 0 degrees with respect to the antenna. This shows the same main lobe geometry as the current testing, notwithstanding the 90 change in antenna orientation. Given these arguments and the previous testing of the identical antenna for our predecessor products in the other orientation with no adverse findings, I think it is safe to conclude that this testing of the YAGI is sufficient for either polarization. 3. Please provide specifications of unique antenna connector that is currently on the module. [LAG] See WBF (000-958) Data Sheet.pdf and WCM (000-957) Data Sheet.pdf for the board and cable connectors. These connectors were designed exclusively for WaveRider, which holds the exclusive rights to these connectors. 4. The test report shows a maximum conducted output power measurement of 27.9 dBm. Other exhibits of the application shows 27.3dBm. Please clarify or supply corrected exhibits (RF exposure, etc.) [LAG] The max. output power is set for each and every modem at the factory during production. We have been setting our current modems to 27.3 dBm and wish to continue to do so. However, during FCC testing, we set the unit to as high an output power as we can and still pass. In this case, the output power is between 27.6 and 27.9 dBm depending on frequency. By having test results showing that we pass at a higher output power than we will be producing gives us confidence that our units will remain FCC compliant. We also prefer the slightly …

Quinlan, Certification Manager, Curtis-Straus LLC, 527 Great Road, Littleton, MA Dear Barry, RE: FCC Submission OOX-915A WaveRider is requesting that Curtis-Straus review and certify our 915A radio as a Digital Transmission System under FCC Part 15. We are applying for a Limited Modular Approval for this radio, since we expect to use this radio in several final products. These final products will all be manufactured by WaveRider only. In accordance with directive DA 00-1407 (June 26, 2000) “Part 15 Unlicensed Modular Transmitter Approval”, I have addressed each of the numbered requirements below: 1. “The modular transmitter must have its own RF shielding”. There are two shields on the radio, one covering the receiver and transmitter circuitry and one covering the local oscillator. Proof that these shields prevent coupling of the RF circuitry and any wiring is provided in the test report showing the results of testing the bare circuit card assembly without any housing. 2. “The modular transmitter must have buffered modulation/data inputs”. The radio accepts data from an Ethernet port only. The radio processors buffer this data and generate modulated signals internally to the radio. The user cannot over modulate or exceed the data rates set by the RF design. 3. “The modular transmitter must have its own power supply regulation”. The 915A uses an external AC to 4.2 VDC power supply to regulate all power coming from the AC lines before it gets to the Circuit Card Assembly. This power supply is included in all testing of this radio. It provides isolation between the radio and the AC lines. Beyond that, there are voltage regulators and power filters on-board the radio to reduce any conducted emissions to the 4.2 VDC line. 4. “The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(c)”. This specific version of the 915A radio complies with this requirement, since it has a WaveRider proprietary unique RF connector. This is the same connector that is used on other WaveRider products (e.g. OOX-EUM3005). Other versions of the 915A radio and its final products may use other RF connectors requiring Professional Installations only. It is for this reason alone that we are applying for a Limited Modular Approval instead of a full modular approval. 5. “The modular transmitter must be tested in a stand-alone configuration”. The 915A is tested as a bare circuit card assembly (CCA). AC power is passed to the AC to 4.2 VDC power supply and hence to the CCA. The power supply is specified as a necessary accessory for this radio. All testing includes the power supply. 6. “The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module”. See “FCC - 915A Product Label.pdf”, submitted as part of the documentation package, to see the format and location of both the label on the radio itself as well as label on the packaged radio. WaveRider Communications (Canada) Inc. Suite 4, 6110 - 1A Street SW, Calgary, Alberta T2H 0G3 Tel/FAX: 403•253•5366 web: www.waverider.com 7. “The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements”. See “FCC/IC – 915A Module Operating Requirements.pdf”, submitted as part of the documentation package, for specific requirements, such as antenna types acceptable, installation requirements, etc. 8. “The modular transmitter must comply with any applicable RF exposure requirements”. See “FCC/IC – 915A Module Operating Requirements.pdf”, submitted as part of the documentation package, for specific requirements, such as antenna types acceptable, required cable losses and separation requirements. WaveRider is applying for a Limited Module Approval for the 915A since future versions of this product will be completely under WaveRider’s control by being the manufacturer and integrator ourselves.

It is a single PCB wireless solution based on the Intersil PRISM II Direct Sequence Chip Set. The 915A is functionally equivalent to the EUM3005 (previously certified with FCC ID: OOX-EUM3005), the EUM3006 (OOX-EUM3006) and the MMT9000 (OOX-WMAN) in regards to frequency of operation, output power, and modulation scheme. The 915A is intended for mounting in variety of chassis, including an indoor plastic enclosure and aluminum enclosure for vehicle mounting. Overall functionality The 915A consists of two main sections; the digital and the RF section. Block diagrams for both sections can be found in the document “915A Block Diagrams”. The digital section contains the following functionality: 1. I/O 2. Ethernet PHY 3. Microprocessor/MAC 4. Memory 5. 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. Reference Oscillator 11. 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…
