1 Mark Hill From: [email protected] Sent: Friday, May 11, 2012 10:42 AM To: Mark Hill Subject: Response to Inquiry to FCC (Tracking Number 875695) FCC Home | Search | RSS | Updates | E-Filing | Initiatives | Consumers | Find People Office of Engineering and Technology Inquiry on 05/09/2012 : Inquiry: FCC - I have a manufacture of a 15.247/15.407 radio device. This device is powered via a Power over Ethernet connection. The product is not intended/marketed to residential use. The manufacturer does not typically provide a POE injector, instead the end-user would need to provide an adequate POE source, either a separate injector device, or a POE enabled switch/router device. As an intentional radiated, that is indirectly powered from AC, it is subject to the requirements of 15.207. The measurements would be performed at the AC input of a typical POE injector. However, it seems that since this product would be not be used in a residential location that testing against the 15.107(b) - Class A requirements would provide adequate protection against interference. Please confirm that for the certification for the 15.247/15.407 operation, that it would be acceptable to use the 15.107(b) limits for the conducted emissions. Thanks - Mark FCC response on 05/11/2012 If it is a part 15 class A transmitter then it needs to be tested for part 15.107 (b) the conducted limits. Part 15.107 (b) is as follows; (b) For a Class A digital device that is designed to be connected to the public utility (AC) power line, the radio frequency voltage that is conducted back onto the AC power line on any frequency or frequencies within the band 150 kHz to 30 MHz shall not exceed the limits in the following table, as measured using a 50 ?H/50 ohms LISN. Compliance with the provisions of this paragraph shall be based on the measurement of the radio frequency voltage between each power line and ground at the power terminal. The lower limit applies at the 2 boundary between the frequency ranges.

The AirFiber radio is a highly efficient 880 carrier OFDM radio utilizing low inter‐carrier spacing (110 kHz) and higher order 256QAM modulation with two transmitters and two receivers in a MIMO configuration. The output stages have been designed for ultra‐low distortion for both the fidelity of the 256QAM modulation, and to meet the spectral emissions at the band edges. These design choices lead to a highly spectrally efficient system with a very sharp roll off at the band edges. Due to the sharp roll off, the spectral measurements are done on an Agilent PXA spectrum analyzer with band power measurements enabled to demonstrate compliance. The main carrier power is set to nominal output to meet 2500mV/m at 3m (as demonstrated in the radiated tests). The measured fundamental power is normalized to 0dB(m) so the band edge rejection can be observed directly. All measurements use average power (RMS) detectors. Out‐of ‐band measurement bandwidths are 1 MHz. On the lowest frequency (shown below), both transmitter outputs are shown to meet the general radiation emission limits of part 15.209 limit of 500uV/m at 3m (which is 74dB below the fundamental output of 2500mV/m) in the first 1MHz below 24.0GHz. TX0 – QPSK Modulation TX0 – 256QAM Modulation TX1 – QPSK Modulation TX1 – 256QAM Modulation On the upper frequency both transmitters meet the specification of part 15.249(d) where out‐of‐band emissions are 50dB below the fundamental power in the first 1 MHz above 24.25GHz. TX0 – QPSK Modulation TX0 – 256QAM Modulation TX1 – QPSK Modulation TX1 – 256QAM Modulation The test station configuration is shown below. The radio board uses a PCB etched OMT to launch into the fixture waveguide where a second PCB OMT picks up and conducts the signal to the measuring analyzer. A 3dB attenuator pad, RF switch (0.7dB loss) and 1m coaxial cable (2.1dB loss) is in line between the test fixture connector and the measuring analyzer.

May 30, 2012 RE: ATCB012146 – Original Equipment & Single Certification Applications – Model: AF24 FCC ID: SWX-AF24 & IC: 6545A-AF24 for Ubiquiti Networks, Inc. 1. Please see UBNT response to the following questions: (a) The submitted test report has field strength measurements made distances less than 3 meters. The attached millimeter wave test procedure shows distance attenuation factors vary with the distance from the device and the size of both the transmitting and receiving horn antennas. How have these factors been taken into account in the submitted test report? Please elaborate on this matter in an amended test report. UBNT: The extrapolation factor used for the measurements made at 5cm from the EUT were 20dB/decade or -35.6dB as stated in the test report. If we apply a 40dB/decade factor (per the MM Wave procedure) from the test distance to the far field point, which for the AirFiber antenna diameter of 25cm is ~20 meters, it will only provide more margin. My best guess on the diameter of the AirFiber antenna is 25cm, but even if I somewhat off, the far field point is much greater than even the specified 3 meter test distance. Applying a 40dB/decade factor to the measured value at 5cm would result in an additional 35.6dB to the margin. I would also point out that the test report notes that, even at 5cm, no signal could be detected above the noise floor of the test equipment which is why we moved so close to the AirFiber for the test. (b) The submitted operation description indicates this is a MIMO device where 2 transmitters operate simultaneously. In the operational description it is unclear what exactly is happening. (e.g., Do the two transmitters send different information or the exact same information? How are they polarized with respect to each other? Etc.) Also the MIMO KDBs attached state that unless circularly polarized antennas are used, the field strength measured from each transmitter must be added together to establish the total (e.g., real) field strength of the transmitter. Please elaborate on this matter in an amended test report and a more detailed operational description. (e.g., Were both transmitters operating during radiated emission measurements? Etc.) Once these matters are resolved for the FCC, IC will accept the results too. UBNT: The MIMO transmitters in the AirFiber data transmissions are completely uncorrelated and independent data streams. Since both transmitter streams are uncorrelated the KDBs 662911 D01 and D02 (attached) explain: 2580 Orchard Pkwy. | San Jose, CA 95131 | U.S.A. | Tel. 1-408-942-3085| Fax 1-408-351-4973. The following text is taken from the KDB 662911 D01 (page 5 bottom and page 6 top): Completely uncorrelated signals include those transmitted in the following modes, if they are not combined with any correlated modes, such as beamforming: •Space Time Block Codes (STBC) or Space Time Codes (STC) for which different digital data is carried by each transmit antenna during any symbol period (e.g., WiMAX Matrix A [Alamouti coding]). •Spatial Multiplexing MIMO (SM-MIMO), for which independent data streams are sent to each transmit antenna (e.g., WiMAX Matrix B. WiMAX Matrix C, which adds diversity, also produces uncorrelated transmit signals). [Note that under previous guidelines, only SM-MIMO signals could be considered uncorrelated for purposes of directional gain computation.] The following text is taken from the KDB 662911 D02 (page 2 bottom and page 3 top): Rules That Specify Radiated Limits (1) If the transmitter output signals are completely uncorrelated as defined in Attachment 662911 D01, of this publication, then each of the two EIRPs or ERPs (total or spectral density) must individually be below the limit.

The operational description uses the words “The multiple input multiple output (MIMO) radio has two identical transmitters and two identical receivers in antenna polarization quadrature to double the transmission capability of the RF channel.” We’ve not been able to find an explanation or definition of quadrature polarization. Please elaborate on this matter for both the transmitted and received signals. I may have used the wrong words for the description of 2 cross polarized antenna probes in our PCB etched OMT. The antennas are 90º cross polarized (orthogonal) to maximize the isolation of the 2 independent MIMO channels. The transmitters/receivers are identical in hardware but each sends its own uncorrelated data. Transmitter OMT Receiver OMT Page 1 of 2Ubiquiti Networks, Inc.

The second question: (a) The operational description states that there are two transmitters but I only see measurements on a high and low channel not for transmitter 1 and transmitter 2 in the submitted test report. Please explain why. We understand what procedure you have used to measure emissions from this device. What we are trying to understand is that this procedure is applicable for the device in question. I did not feel that the differences in the power spectral density warranted a second set of plots. The hardware is extremely balanced in its performance (this is required to allow recovery of the independent data streams). The two transmitters send independent data streams, but the modulation type (880 carrier OFDM with QPSK/256QAM modulation) at any time is the same on transmitter1 and transmitter2. I can test the second transmitter if you wish and send you the added plots. Please feel free to contact me (I am available for phone calls also) if you have further questions.
