AB6NT800MFRMCDMA Cellular Base Station

Received March 6, 2001 at AmericanTCB: Bill, This email is intended to provide clarification on the operation description provided in the AB6NT800MFRM filing. The title page for this exhibit included in the filing was incorrectly labeled 1900 MFRM. It should actually read 800 MFRM in place of the 1900 MFRM. The content of the operational description contains references to both 1900 MFRM and 800 MFRM because this is a common platform, which utilizes both radios. The 1900 version will be submitted for approval in the next couple of weeks. Please do not hesitate to contact me with any further questions or clarifications required for this filing.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 February 7, 2001 Glen, There are a number of issues on this application which will have to be addressed.: 1.) The label for this product is wrong. It indicates an AB6NT1900MFRM. Please correct 2.) The exterior photographs are not very helpful. Please provide additional detailed views showing all surfaces, and all exterior controls and ports. 3.) A line drawing or photo showing placement of label is required. The existing drawing does not clearly identify where the label will be placed. Perhaps a photograph using a “dummy “label would be appropriate. 4.) Interior views must be at minimum top and bottom of all circuit boards, plus overall “case open” views showing general construction features. 5.) The 731 form indicates three emission modes are available, however the Test Report only identifies two. Please address. 6.) The frequency table in Section 3.6 only identifies the IS-95 valid channels. Is this table of any use in a three channel implementation? 7.) FYI: Section 3.15 quotes ANSI J-STD-008. This is a PCS band specification, and not necessarily appropriate to 800MHz Cellular systems. 8.) FYI: In the past for occupied bandwidth, I have found 1M25 IS95 emissions best measured with a span of 7.2MHz, or 5 times the chip rate (1.228MHz) plus a fudge factor of 30KHz for RBW. I am certain these settings would work on wider emissions as well. 9.) Using the FCC 1% of 99% bandwidth rule of thumb, three carrier Occupied BW plots should use an RBW not less than ~37.5KHz. Please correct. 10.) Why was a VBW less than RBW used for Section 4.3.2? In general VBW must be equal or greater than RBW. Data should also be presented for one and three channel systems 11.) Recent interpretations by the Commission require the use of substitution method for TX radiated spurs. Methods which quote ANSI C63.4 for any work other than Part 15 are considered unacceptable. Values should be presented in dBc relative to full power, or dipole equivalent ERP. For this broadband emission, please include RBW and VBW settings with the data. Please provide information on both one and three channel setup 12.) Operational description should at least include an explanatory letter about the title page and addressing the AB6NT1900MFRM issue. 13.) FYI: Radio Test Setup photos are not required for licensed radios. 14.) Please provide justification for emission designators. 15.) Please provide band edge data per 22.901(d)(2). William H.

RF Exposure Guidelines for Cellular and PCS Antenna Sites Document no: SI-EMR-R01.5 Author: Rupinder Randhawa Proprietary The information disclosed herein is proprietary to Nortel 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. Northern Telecom Antenna Siting Guideline ii 1.0 Executive Summary This document serves as a guideline for the deployment and installation of Northern Telecom’s 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 Uncontrolled Controlled Frequency Band r [ meters ] r [ meters ] Cellular r0.300ERP= r0.135ERP= PCS r0.228ERP= r=0.102ERP DCS r0.228ERP= r = 0.102ERP 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 electromagnectic fields in question. This typically pertains to trained staff that are 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’s 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 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 affect. The requirement for installers to evaluate the exposure at an installation takes effect Sept. 1/97. The exposure limits should apply now to all known sites since existing facilities are not exempt or grandfathered 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 are 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 filed with the FCC, unless requested by the FCC for substantiation. Where Nortel 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 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 station transmits at 100 Watt ERP or more. Northern Telecom Antenna Siting Guideline 2 3.0 Guideline The objective of the Environmental Evaluation is to ensure that human exposure to RF energy does not go beyond the maximum permissible levels stated in the FCC Guidelines, FCC 96-326. Therefore certain sites do not require an evaluation by nature of its design. It could be that the antennas are placed high enough thereby resulting in extremely low RF fields by the…
