American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 May 12, 2003 RE: Vivato, Inc. FCC ID: QLNVLJ24WFSW 1) The application mentions that the FCC conversations may be considered confidential but was to be determined when the application was originally uploaded. Please confirm if this information is to be considered confidential. Note that if it is considered as confidential, the confidentiality request letter must be updated to include this. Response : The FCC conversations do not need to be considered confidential. 2) The application discusses that complementary beam forming is a future option and must be discussed further with the FCC before it is found to be acceptable. However in one of the Q/A files, it is mentioned that this feature may be turned on/off at will. Please explain if this feature is currently available, and if so is has there been any further discussion between the FCC and Vivato that can be provided on this topic. Response : The feature is not currently available in this Vivato product. Neither the software nor the hardware are part of the current unit. 3) From the labeling, it appears that the device is being subjected to a Declaration of Conformity as a PC peripheral device. However, the DoC labeling is missing the required "FOR HOME OR OFFICE USE" as specified by 15.19(b). Please note that although the phrase "Tested to Comply with FCC Standards" is also missing, this phrase is not necessary when the 2 part statements as given in 15.19(a)(3) for a Certification are also on the device. Response : The label has been modified to comply with 15.19. Please refer to the revised label exhibit uploaded with this response. 4) Since this device is also considered a PC Peripheral authorized using a DoC, then a compliance information sheet should be included in the manual or as a separate sheet. It may be best to include this information on the same page as your FCC statements. The compliance information sheet must contain the following information: COMPLIANCE INFORMATION (47CFR 2.1077) If a product is tested and authorized under a Declaration of Conformity, a compliance information statement shall be supplied with the product at the time of marketing or importation, containing the following information: (1) Identification of the product, i.e. name and model number. (2) A statement similar to that contained in Section 15.19(a)(3) that the product complies with Part 15 of the regulations. (3) The identification, by name, address and telephone number, of the responsible party. The responsible party is defined as either the manufacturer, or if the equipment is imported, the importer. The responsible party for a Declaration of Conformity must be located within the United States. Response : A revised user guide, with the compliance information added, has been uploaded with this response. A Class B DoC Report is available upon request. 5) For data given in section 3.2 of the test report, please confirm that the device was fully rotated to obtain worse case positioning for azimuth each result. Response : During all the radiated testing, the unit was rotated to obtain the worst case positioning. 6) There appears to be an error in the calculations in Table 3.5-1, 3.7-1, 3.8-1, 3.9-1, 3.10-1, 3.10-2, & 3.10-3. The corrected level does not appear to equal the reading + insertion loss of the filter. Please note that the first few tables did appear to be correctly calculated. Please explain. Response : The errors have been corrected; please refer to the revised test report uploaded with this response to find the appropriate values. 7) Regarding AC conducted emissions, no data appears to have been taken below 450 kHz. Please confirm that the emissions were scanned from 150 kHz to 30 MHz. Response : Points below 450 MHz were investigated, but only the highest levels were recorded in the test report. 8) For section 5 of the test report, please provide information regarding the RBW and VBW settings for the various measurements made. For measurements above 1 GHz, only average measurements have been shown. Since there are also peak limitations as specified by 15.35(b) of the rules, please provide information regarding the peak to average ratio of emission > 1 GHz. Additionally, these measurements are required by 15.109 of the rules, not 15.209. Please correct. Response : The purpose of 15.35(b) would be to see the difference between the peak and the average values for a modulated signal, and the effect of the duty cycle, in such case only the harmonics and the carrier would be affected. For the receiver noise, the levels of the spurious emissions are not affected by the modulation and/or the effect of the duty cycle. In this case, only an average measurement is sufficient to show compliance with the FCC limits. 9) All of the spurious radiated data (i.e. Section 6.5/6.6/6.7) appears to show maximization at one angle of 40 degrees. However, this data was taken for 3 different zones (1, 6, or 13), each of which should occur at different angles from the antenna. Please explain. Response : The harmonics are not supposed to radiate at the same angle as the carrier does. As a result, most of the noise was found at 40 degrees. 10) The test procedure in section 7 mentions a 300 kHz VBW, but only 100 kHz VBW was used. Please correct. Response : The report has been corrected; please refer to the revised test report uploaded with this response. 11) Table 9.29 appears to show failing data, but the data appears to be place into incorrect columns. Please correct as necessary. Response : The report has been corrected; please refer to the revised test report uploaded with this response. 12) As given in this application, the output power is not simply the power into one of the 16 points, but requires combining all 16 ports in order to obtain the true effective output power. This suggests that the spectral density test should also be considered as a summation. However, given the f…

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 June 5, 2003 RE: Vivato, Inc. FCC ID: QLNVLJ24WFSW Date of Original Email: 06/04/03 731 Confirmation Number: TC464457 Correspondence Reference Number: 8486 1) The operational description presented and approved by the FCC listed a 100 mW maximum output power per channel. The application is requesting 119 mW per channel. Response : 119 mW (20.8 dBm) is the highest measured power output of the unit tested, not the target of the manufacturing process. The Vivato 2.4 Ghz Wi-Fi Switches are currently set at the factory to a level of 80 mW (19 dBm) per channel. This represents the combined conducted power to all 16 antennas elements. It has been determined that during production, the power settings are subject to ±2 dB of manufacturing variation. The point-to-point rules for a 25 dBi antenna gain allow up to 23.67 dBm conducted power, giving the Vivato Switch nominally a 4.67 dB margin and a worst case margin of 2.67 dB. Vivato believes its products are in compliance with 47 CFR 2.1073 in that the unit tested is within the variations that can be expected due to quantity production. 2) The operational description presented and approved by the FCC stated a system with a single 100 degree beam width. The manual indicates that the unit can be combined with four units to form a 360 degree coverage area. Please explain/correct the manual. Response : The manual being shipped with the Vivato 2.4 GHz Wi-Fi Switch has already been corrected. The statement regarding combining four units to form a 360 degree coverage area has been removed. Please refer to page 1 of the user manual introduction for the new text. In addition, the training documentation (uploaded to support this response) specifies that antennas must be placed a minimum of 10 meters away from each other. 3) The grant condition should clarify that the listed output power is the total of all ports per channel. Response : The listed output power is indeed the total of the power conducted to all 16 antenna feeds. The grant condition will be revised by ATCB. American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 4) The RBW of the measurement instrument used for making conducted output power must be greater than the 6 dB bandwidth of the emission. It appears that instrumentation used for the test has a maximum bandwidth of only 5 MHz. Please correct/retest accordingly. Response : The measurement listed in the report with the power meter and sensor was verified using the Substitution Power Measurement Method with a signal generator, power meter, diode detector, and an oscilloscope. The measurements were the same. The power meter results were recorded in the report. We have experienced negligible difference between the power meter and the linear substitution method for DSS, and OFDM wide band modulations. 5) The 6 dB bandwidth must take into account the Widest points above and below the peak that are 6 dB down from the peak. Response : Such plots were taken at the time of testing. The report has been modified to show the appropriate 6dB BW plots. 6) The RF safety review is pending, questions may be forthcoming. Please note that the output power and new proposal to combine 4 units at one location will affect RF safety evaluation. Response : Although earlier pre-shipment versions of the User Guide for the Vivato 2.4 GHz Wi-Fi Switch mentioned the co-locations of up to 4 switches; Vivato's manual has been revised and does not mention co-location of multiple panels. Please advise if there are any questions. Sincerely, Rachid Sehb Rhein Tech Laboratories
