Motorola, Inc. Reply to ATCB Comments 091607 for FCC certification of PHX-CPE25100 1) FYI....A Permit but ask inquiry has been submitted to the FCC and awaiting a response. 1) The power requirements require peak power, but plots appear to suggest an average was used. Please explain. a) Please note the following discussion previously made with the FCC: i) Text of Inquiry: Testing Peak power in the 4.9 GHz public safety band. Part 90.1215(c) states: (c) The peak transmit power is measured as a conducted emission over any interval of continuous transmission calibrated in terms of an RMS-equivalent voltage. Please give a more thorough explanation to what calibrated in terms of an RMS-equivalent voltage means and give an example or two of valid measurement procedures. ii) -------------------------------------------------------------------------------- iii) Response to Inquiry: iv) For reference, here is text of 90.1215(c): v) "The peak transmit power is measured as a conducted emission over any interval of continuous transmission calibrated in terms of an RMS-equivalent voltage. If the device cannot be connected directly, alternative techniques acceptable to the Commission may be used. The measurement results shall be properly adjusted for any instrument instrument limitati! ons, such as detector response times, limited resolution bandw! idth cap ability when compared to the emission bandwidth, sensitivity, etc., so as to obtain a true peak measurement conforming to the definitions in this paragraph for the emission in question." vi) Note this appears to have omitted words, compared to similar text at 24.232 and 27.50, and should read: "The peak transmit power is measured as a conducted emission over any interval of continuous transmission using instrumentation calibrated in terms of an RMS-equivalent voltage. ..." vii) The power output should be measured with the actual modulation to be used with the device and as shown in the emission designator requested. viii) For example, using a spectrum analyzer with settings: ix) • RBW > signal BW x) • VBW > RBW (prefer VBW > at least 3x RBW) xi) • no averaging xii) • "trace max hold" xiii) Most spectrum analyzers use a detector that is calibrated in terms of RMS voltage. Some instrument manufacturers may use the term "detector type," which could be better termed "detector display setting," i.e., sample, average, peak, and sweep time. 90.1215 requires maximum peak, so the measurement settings should be adjusted to get the highest value, which for some analyzers means detector type should be selected as "peak." Sweep time may also need to be varied to maximize the peak value. It is suggested that the VBW be set to at least three times the RBW. When using a peak power detector, the maximum-hold feature should be employed. With regard to the associated analyzer settings, for peak-power measurements, the default sweep-time for the selected span and RBW could be used, which when combined with max-hold should ensure detection of the maximum peak power level. b) Motorola reply: Test Report updated. Page 1 of 6 9/26/2007 Motorola, Inc. Reply to ATCB Comments 091607 for FCC certification of PHX-CPE25100 3) Shouldn’t the emission designator follow the 26 dB bandwidth on the 731 form as specified by 27.53(l)(6)? This may affect test report and operational description. a. Agreed, Form 731 updated for emission designator and frequency range. 4) Please explain the actual lowest/highest channels for each bandwidth. It appears that this would be 2499 – 2687 for the 5 MHz bandwidth. How about the 10 MHz bandwidth? It would seem that the 10 MHz bandwidth fundamental would fall outside of 2496 – 2690 (allowed band). a. All measurements for this FCC certification were performed on center frequencies of 2499, 2593 and 2687 MHz regardless of emission bandwidth and FCC channel bandwidth. A WiMax transmission using a 5 MHz emission can fit within either a 5.5 MHz or 6 MHz channel as designated by the FCC frequencies listed in Part 27.5. The 10 MHz WiMax emissions will require channels to be aggregated. The minimum channel bandwidth that would result from adjacent channels would result in 11, 11.5 or 12 MHz channel bandwidths. If BRS Channel 1 and EBS Channel A1 are aggregated, the resulting useable spectrum would be 2496 – 2507.5 MHz or 11.5 MHz bandwidth. For this particular case, the lowest center frequency that the 10 MHz WiMax emission could utilize would be 2501 MHz. On the high end of the BRS/EBS band, there are two BRS channels at the end of 5.5 MHz each. The highest center frequency that could be utilized for a 10 MHz transmission would be 2685 MHz. The plots shown below contain the mask information at the 2496 MHz edge and the 2690 MHz band edge. The transmitter power and opposing mask edge are not valid in these plots.

Reply to ATCB Comments 091607 for FCC certification of PHX-CPE25100 Fo=2685 MHz, 10 MHz emission 5) For spurious emissions, where is the data for 2480 – 2496 and 2687 – 2700 MHz. This appears missing. a. Plots of the spurious emissions from 1 to 5 GHz are located in the 5A Test Report document on page 41. Additional plots are provided below: Fo=2499 MHz, 5 MHz emission Page 3 of 6 9/26/2007 Motorola, Inc.

Reply to ATCB Comments 091607 for FCC certification of PHX-CPE25100 Page 6 of 6 9/26/2007 Fo=2687 MHz, 10 MHz emission 6) EMC report appears to use a -13 dBm level. Shouldn’t this be -25 dBm limit? Note that 7.497 GHz may be a problem. a. The 731 form has been updated to show the correct equipment classification in addition to test report emissions limits.

RE: Motorola, Inc., Reply to ATCB Comments 100107 FCC ID: PHX-CPE25100 After a review of the submitted information, I have a few comments on the above referenced Application. Depending on your responses, kindly understand there may be additional comments. 1) I am still unsure why 10 MHz plots are shown centered on 2499 and 2687 MHz channels if this is not a normal 10 MHz channel per your response. Kindly explain. Do I need to re-measure the 10 MHz emissions at the band edges? The frequencies that were used to test were chosen to be the same for the 5 MHz and 10 MHz channels only to reduce any confusion that could arise from having to test with a minimum of 6 channels for FCC and an additional 4 for Canada. I believe that the information supplied shows that the transmitter would comply to the emission limits regardless of shifting the transmitter center frequency a couple of MHz. 2) Many of the limits for spurious emissions in both test reports still cite -13 dBm when it appears that -25 dBm is relevant. Please comment. This product is more suited for the 27.53L(2) classification as a Temporary Fixed device, a desktop device that requires a 120 VAC power source. In addition the antenna is directional which introduces its own set of issues within a mobile application. I was not attempting to have this classified as a "mobile" device, only to show that it complied to the same requirements as a "mobile" device with respect to the emission limits. I had changed the information in the test report to reflect the 27.53L(4) requirements of -13 dBm. The revised information is shown in "5Aa Test Report.pdf" I also uploaded a new ATCB application form indicating the "Temporary Fixed" classification. 3) Note that generally the -13 or -25 dBm limits should utilize the same detectors as required for peak power. If rules specify average power – then average must be used. If rules specify peak power, then peak must be used. Note that radiated and conducted plots appear to utilize average detectors/techniques. However I am inquiring with the FCC to be certain on this aspect. (see attached) The "5B EMC Test Report" indicates that the radiated signals within 20 dB of the -13 dBm limit are peak measurements. These signals were then verified with generator/antenna substitution as described in TIA-603-C. The conducted emissions measurements were performed with the same detector as used for power measurements, i.e. "instrumentation calibrated in terms of rms-equivalent voltage". 4) FYI....Regarding the -25 dBm limit. The rule is not clear if the -25 dBm is at the bandedge only, or all spurious emissions. Given the wording, and intent, it would seem this is all spurious emissions. However we are inquiring with the FCC to be certain as well. (see attached) A resolution to this will be necessary for future submissions, but is not a barrier to the requirements for this specific product. 5) FYI....FCC Permit but Ask inquiry is awaiting final report. Unless you need to have the 10 MHz bandwidth actually re-measured, I believe the "5Aa Test Report.pdf" is ready for go.

RE: Motorola, Inc., Reply to ATCB Comments 100207 FCC ID: PHX-CPE25100 After a review of the submitted information, I have a few comments on the above referenced Application. Depending on your responses, kindly understand there may be additional comments. 1) Normally a device should be capable of behaving in a way that allows use outside of the rules. Therefore our concern regarding the 10 MHz plots is what keeps the device from allowing the band to be centered on 2499 and 2687 MHz channels if this is not a normal. While it is understood why you may have tested this, if the device is capable of operating on these channels, this would allow operation beyond what would be approved (due to bandedge requirements, etc.). Please explain. The CPEi25100 device operates within the WiMax protocol (IEEE Std. 802.16e-2004). This device will contain a table of frequencies that will be scanned for availability of a suitable base station signal. During the scanning process, a list of base stations is complied. Once the device has completed scanning its table of frequencies, it will return to the base station that produced the best overall receiver performance. The device will then transmit, for the first time, to register with this base station. The actual frequency of operation of this device is tied to the frequency of operation of the base station with which it has registered. In addition this device does not contain mechanical or software programmable controls or capabilities that are available to the end user for adjusting the RF transmitter level or frequency of operation. 2) Regarding previous comment 3, for RF conducted spurious emissions, the detector shown on most the plots appears to be AVG. The transmitter spurious emissions measurements were performed with the guidance of the procedure contained in the TIA Standard TIA-603-C Land Mobile FM or PM – Communications Equipment – Measurement and Performance Standards, clause 2.2.13, which indicates that the detector should be “mean or average power”.

The recorder output from the RAHAM meter is applied to the Fluke DVM. The DC level of the Recorder Output is recorded and then converted to the corresponding maximum permissible exposure value. The recorder output at a full scale reading is 124 mV. The measurements performed for this report utilize the 2 mW/cm 2 setting of the RAHAM instrument. 8.3 General Information The Motorola, Inc. CPEi25100 WiMax transmitter can apply 0.5 watts of RF power, within a channel, to the integral antenna in the 2496-2690 MHz band. The CPEi25100 has a maximum transmit duty cycle of 49.37 % per the 802.16e protocol and is based on a TDMA frame. The vertically polarized antenna has 13 dBi of gain. Therefore, the maximum radiated transmit power with all sub-channels enabled is as follows: 49.37% Transmit Duty Cycle: Pmax = Ptx(dBm) + G(antenna(dBi)) - 10*log(duty cycle)(dB) Pmax = 27 + 13 - 10*log(0.4937) = 27 + 13 – 3.0654 Pmax = 36.9346 dBm EIRP = 4.937 Watts EIRP Calculations: The following calculations …
