Subject: Request for Confidentiality FCC ID: AB6BTS6000 To Whom It May Concern: In accordance with §0.459 of CFR 47, Nortel Networks requests confidentiality for the following items 1. Block Diagram (Exhibit 3) 2. Schematic Diagram (Exhibit 4) 3. Part List (Exhibit 5) 4. Operational Description (Exhibit 6). 5. User Manual (Exhibit 8) 6. Internal Photo (Exhibit 9) These items contain detailed system and equipment description and related information about the product which Nortel Networks considers to be proprietary, confidential and a custom design which otherwise would not be released to the general public. Since this design is a basis from which future technological products will evolve, Nortel Networks Corporation also feels that this information would be of benefit to its competitors, and that the disclosure of the information in these exhibits would give our competitors an unfair advantage in the market.

Introduction This memo provides inputs with regard to the assessments of Health protection and radiation hazards expected from Nortel GSM 6000 BTS compliant with the North American requirements (FCC OET Bulletin 65) through calculation as described below. 2. Radiation hazards a. iBTS radiations The maximum radiated power level authorized by the EMC specifications is : • –36 dBm (or E=2.7 mV/m) for frequencies between 30 MHz and 1 GHz, • –30 dBm (or E=5.4 mV/m) for frequencies above 1 GHz. According to FCC OET bulletin 65, the power density is linked to the E field by the relation S=E²/3770. As a consequence, the maximum power density radiated by the iBTS will be : • S=1.9*10 -9 mW/cm² for frequencies between 30 MHz and 1 GHz, • S=7.9*10 -9 mW/cm² for frequencies above 1 GHz. The North American Maximum Permissible Exposure (MPE) levels for general population (uncontrolled exposure areas) are defined in the table below : Page 2 Nortel Networks Products Approvals Team Parc d'activité de Magny-Chateaufort CHATEAUFORT 78928 Yvelines Cedex 9 - France Tel +33 (0)1.69.55.44.44 Fax+33 (0)1.69.55.30.01 Frequency range (MHz) MPE (S, mW/cm²) 30 – 300 0.2 300 – 1500 f/1500 1500 – 12750 1.0 b. Radiation of a system Considerations : • BTS configured with 1 Power Amplifier (PA) by sector, PA configured at maximum output power (30 Watts). • Feeder losses # 1 dB. • Antenna gain G=18 dBi # 63. The power delivered to the antenna (per PA) is given by P=PA_power – DDM_losses – Feeder_losses # 43.3 dBm (or 21.3 Watts). As described in FCC OET Bulletin 65, the power density can be estimated by S=P*G/4πR² where R is the distance to the source (the antenna). The Maximum Permissible Exposure (MPE) level for uncontrolled access locations is S = 1 mW/cm² at the frequency of GSM 1900 signal. As a consequence, the safe distance approach is with the aforementioned considerations R = 3.27 m. This distance is the one at which the limit level will be reached in the main beam of the antenna and would usually be achieved by the fact that this antenna is mounted on a pole. 3. Conclusion As demonstrated before, it is deemed that Nortel 1900 MHz GSM 6000 BTS complies with the general requirements (FCC OET bulletin 65) for health protection. It should also be noted that exposures inside a building can be expected to be reduced by at least 10 to 20 dB due to the attenuation caused by building materials in the wall and roof of the building (source : FCC OET Bulletin 65).
