October 18, 2004 RE: FCC ID: PHX-OSU2400A_ATCB001810 Attention: Tim Blom I have a few comments on this Application. Please note that further comments may arise in response to answers provided to the questions below. 1. Please note that the frequency stated on the 731 for a part 15 device must be the operating frequency range of that device. Please note that means that you must clearly identify the lowest and highest operating frequency of the device for Part 15. Please provide a 731 that clearly identifies these frequencies. 2. FYI - Please note that the power listed on the grant and thus approved for this device is the power actually measured during testing, not the 27.16dBm listed at the top of page 9 of the report. Consequently, the 731 is incorrect and should state 494mW as the 15.247 power and not 520mW. It is this 494mW that will be listed on the grant. 3. Please note that the Block diagram indicates that the device operates over the full range of 2400 to 2686MHz. Please note that this is not possible. Please provide a block diagram specifically addressing the part 15 device and one specifically addressing the part 21 device. Alternately, please address the specific frequency ranges for the individual rule parts specified. While they may be in the same document, you must clearly identify the transmitter and operating frequencies for the specific rule parts. 4. Please note that this device appears more than sufficiently large to contain the required 2 condition statement of part 15.19. Consequently, this statement must be on the product not in the manual. Please provide a sample label with this required statement. Alternately, please explain how the exemption of section 15.19(a)(5) applies to this transmitter. Please note that size would not appear to be a valid reason. 5. Please note that the operational description would indicate that the device could transmit over the full range of 2400 to 2686MHz. Please provide evidence that the device only transmits in the allowed bands for the rule parts for which certification is being applied and that it does not operate in the restricted band between 2483.5 and 2500MHz. Please explain how the device is restricted from operating in the disallowed frequency bands. Please also justify the use of this device in under Part 74 (i.e. how or for what purpose is the device used under Subpart I of part 74?). 6. Please note that Public Notice DA-02-2138 is a test procedure specifically for UNII devices under 15.407. Please note that DTS transmitters under 15.247 should use FCC publication 558074 “New Guidance on Measurements for Digital Transmission Systems in Section 15.247”. While the test methods are very similar for peak power measurements, the correct reference for 15.247 devices should be maintained. 7. Please note that while digital device radiated emissions may be measured using CISPR limits and test methods, radiated spurious emissions in the restricted bands for 15.247 devices is not a digital device measurement and cannot be performed in accordance with CSIPR22 limits. They must necessarily be performed to 15.209 limits. Reference to the proper limits applicable for specific rule parts needs to be consistent. Of primary concern is the fact that these radiated emissions are not confused with digital device emissions and that the transmitter characteristics and test methods are not confused or intermixed with digital device test methods. Please confirm that CISPR 22 test methods were not inappropriately used to measure intentional radiator spurious emissions in the restricted bands and that proper DTS intentional radiated test methods (not digital device test methods) were properly followed. 8. Please note that ANSI C63.4 1992 is not the appropriate test method. Please note that it has bee more than a year since the FCC has mandated ANCI C63.4 2001 and the latest revision of C63.4 (2003) is now expected. Please provide evidence that ANSI C63.4 2001 has been properly incorporated in the testing of the part 15.247 device. 9. Please note that 15.247 devices are Frequency Hopping SS or digitally modulated. Your report and documentation mentions the use of ‘other modulation’ techniques. Please verify that only the approved technology specified in the 15.247 frequency range is used. 10. Please note that your specified separation distance in the manual is listed as 20cm. The safe distance calculated in your MPE report is 25.29cm. Measured MPE at 20 cm was also performed to show that the 20 cm separation distance was sufficient. However, the MPE test procedure does not explain much about the actual test performed. The procedure simply states that the probe was set 20cm away from the EUT. While some assumptions can be made about projected exposure, nothing was provided to address the probe positioning in the field. Was the probe moved within the field to establish if the worse case MPE was measured? What steps were taken to insure that the worse case MPE was determined? What steps were taken to insure that proximity of the probe to the EUT was not a factor causing lower readings than actually generated? Please explain. 11. Please note that the table on page 3 of the part 21/74 report states that the conducted power of the device is 1.932W. The test procedure mentions the use of an analyzer, attenuators and a switch. However, nothing was mentioned about any cable loss that may have been in the measurement system. For example, if a cable with 1dB loss was used, the device fails the maximum 2Watt limit. Please provide the cable loss information in the test setup, and please verify that the inclusion of the cable loss does not cause the device to exceed the limit. 12. Please note that the EIRP/ERP of a licensed device needs to be measured using the antenna substitution method in accordance with the acceptable test procedures and should not be calculated. While the calculated EIRP shows that the expected measured EIRP would still be below the limits, it i…

Please explain how the device is restricted from operating in the disallowed frequency bands. Please also justify the use of this device in under Part 74 (i.e. how or for what purpose is the device used under Subpart I of part 74?). Reply: The channel plan for this product is contained in the software that is loaded when the product is manufactured and is not accessible by the end user. The channel plan does not allow the center frequency and modulation bandwidth to go below 2401 MHz or above 2479 MHz for the ISM band. The channel plan for the MMDS/ITFS spectrum is 2500 – 2686 MHz. This device operates in the ITFS spectrum (47 CFR Part 74) as allowed by FCC rules. 10/28/2004 Reply to comments from ATCB October 18, 2004 6.

Please verify that only the approved technology specified in the 15.247 frequency range is used. Reply: The NextNet Wireless system utilizes Orthogonal Frequency Division Multiplex (OFDM) modulation which is a method of digital modulation in which a data stream is split into multiple narrow band channels of contiguous but different frequencies. The FCC has ruled in FCC 01-158 that OFDM is a suitable modulation format for devices compliant to 47 CFR 15.247 using digital modulation. Each of the discrete frequencies that make up the OFDM modulated signal are modulated with a 4, 16, or 64 Quadrature Amplitude Modulation (QAM) format which has also been recognized by the FCC as a digital modulating function as described in ANSI C63.17-1998. 10/28/2004 Reply to comments from ATCB October 18, 2004 10.
