AB6NT1900MFRM2CDMA Cellular Base Station

Original Equipment Certification Application - Additional Information March 31, 2002 American Telecommunications Certification Body, Inc. 6731 Whittier Avenue Suite C110 McLean, VA 22101 RE : Original Equipment Certification Application FCC Tx ID : AB6NT1900MFRM2 Dear Sir/Madam This letter is to respond the additional information that requested by ATCB. The responses to your comments are listed below: Question 1) The internal photographs should include the top and bottom of all boards included in the RF path. It appears that some photographs may be missing (i.e. bottom photograph of PA board). Please provide any missing photos. The picture for the bottom side of the PA board wasn’t submitted because there was no circuitry at the bottom side and also the bottom side of the PA board was glued to the heat sink through thermal glue. As requested, a picture was taken to show the bottom side of the PA board with the heat sink attached and included in the “Exhibit 6 – Internal Photos”. The updated document was submitted to the ATCB web site as “Additional Information”. The updated “Exhibit 1 – Certification Application” letter was updated to reflect of adding an extra exhibit and was submitted to ATCB web site as well. Question 2) Please provide a clearer or higher resolution copy of the label. The characters must be easily distinguished. As suggested, a much clearer label drawing has been provided and submitted to the ATCB web site as “Additional Information”. Question 3) Please provide a separate exhibit for the test configuration photographs. As suggested, the test configuration photographs has been submitted as “Exhibit 11 – Test Setup Photos” to the ATCB web site under “Additional Information”. Question 4) Section 6 of the 731 form appears to list RX frequencies. Please update this section to list the TX frequency range. The frequency range stated in Section 6 of Form 731 was 1930 to 1990MHz. The frequency range stated is the Tx frequency range of the CDMA PCS band basestation and should be correct. Question 5) Please provide information regarding DC voltages/currents applied into the several elements of the final radio frequency amplifying device for normal operation over the power range The information requested is provided in the updated “Exhibit 2 – Test Report Summary” and submitted to the ATCB web site as “Additional Information”. Question 6) The test report seems to present radiated spurious test data following typical radiated methods such as ANSI C63.4 and then calculating TX power limits via far field equations. Please note that when the limits are given for ERP/EIRP and in dBc (43 + 10 log P) then the device must be tested following substitution methods specified in EIA/TIA 603. Please reference email interpretation from Frank Coperich that defined this policy provided in a separate attachment. As suggested, CMAC has updated and included the “substitution method” in the test report. The updated test report has been submitted as “Exhibit 2B – Test Report Provided by CMAC” to the ATCB web site under “Additional Information”. Please contact me for further information if necessary.

EXHIBIT 10 RF Exposure Guidelines for PCS and Cellular Applicant: Nortel Networks Inc. For Original Equipment Certification on: AB6NT1900MFRM2 RF Exposure Guidelines for Cellular, PCS and LMDS Antenna Sites Document no: SI-EMR-R01.5 Authors: Product Integrity BWA – RF Engineering Microwave Radio Design Proprietary Northern Telecom Antenna Siting Guideline 3 The information disclosed herein is proprietary to Nortel Networks or others and is not to be used by or disclosed to unauthorized persons without the written consent of Nortel. The recipient of this document shall respect the security status of the information. 1.0 Executive Summary This document serves as a guideline for the deployment and installation of Nortel Networks’ wireless base station equipment with respect to the control of electromagnetic radiation (EMR) exposure. The objective is to provide guidance on where antennas can be deployed, how to calculate power densities and safe distances and how to protect users from excessive exposure to electromagnetic radiation. This guideline is in response to recent regulatory requirements originating in the US aimed at controlling human exposure to EMR. Safe distance formulae for base stations: Limits Application Uncontrolled r [ meters ] Controlled r [ meters ] Cellular r0. 300 ER P= r0. 135 ER P= PCS r0. 228 ER P= r= 0.102 ERP DCS r0. 228 ER P= r=0.102ERP LMDS r = 1 r = 0.4 P-to-P Microwave Radio r = 1 r = 0.4 Uncontrolled refers to situations where individuals are either unaware or not in control of their exposure to the electromagnetic fields in question. This typically pertains to the general public. Controlled refers to situations where individuals are both aware of and in control of their exposure to the electromagnetic fields in question. This typically pertains to trained staff that is in contact with these fields as a result of their employment and have authority to limit their exposure. Note: This document includes DCS in its examples. If the EU adopts ENV50166, or any other EMR standard, then that document will replace this as the guideline for DCS products. Until that happens, these limits can be used to ensure due diligence on Nortel Networks’ behalf.

FCC’s OET Bulletin #65 (versions in progress) addresses calculation and measurement procedures to determine compliance with the FCC limits which includes the 800 MHz cellular and 1.9 GHz PCS bands. The equipment and its associated deployment must comply with FCC Guidelines, ET Docket No. 93-62, Released August 1, 1996, (FCC 96-326). This standard is largely based on the limits and test methods outlined in IEEE C95.1-1982, NCRP Report No. 86 and C95.3-1982 respectively. The applicable portions of both are summarized in this document to assist in the antenna site planning to ensure compliance. The exposure limits are currently in effect. The requirement for installers to evaluate the exposure at an installation takes effect on Sept. 1/97. The exposure limits should apply now to all known sites since existing facilities are not exempt or grand fathered from the new rules. The FCC has determined that certain sites will require “Environmental Evaluations” in order to show compliance to the standards. Adhering to these guidelines can ensure compliance to the standard, and therefore can be the basis for the Environmental Evaluation. Please note that some installations do not require such routine evaluation: exceptions are noted further in this document. Adherence to these guidelines is recommended to promote safety. An installation of equipment that is identified as exempt may require an Environmental Evaluation if the combined energy of other Radio Systems at the site and the new installation could reasonably exceed the safety limits. Environmental Evaluations are kept on hand, as opposed to file with the FCC, unless requested by the FCC for substantiation. Where Nortel Networks is responsible for installing or engineering base stations, the person in charge should be aware of and have access to documentation for making an Environmental Evaluation. Also, Nortel Networks will need to maintain documentation for assurances to the FCC that Environmental Evaluations have been conducted for each radio station that uses our Experimental Radio License, or STA, where the statio…
