Subject: Request for Confidentiality FCC ID:AB6S8000BTS To Whom It May Concern: In accordance with §0.459 of CFR 47, Nortel Networks Corporation 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 7) 6. Internal Photo (Exhibit 9) These items contain detailed system and equipment description and related information about the product which Nortel Networks Corporation 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.

The product for which certification is sought is Nortel Network’s 850 MHz/1900 MHz GSM indoor and outdoor base stations (S8000). All detailed information for the system is included in the respective exhibits as required by the Rules. The S12000 was previously certified for the following configurations- FCC ID numbers: AB6S8000 850/1900 MHz dual Band – 850MHz single band – 1900MHz single band HePA 1900Mhz ( GMSK 60W / 8PSK 45W) GMSK modulation code 8PSK modulation code H4D coupler H2D coupler Duplexer Please reference the above filings for conducted test data and documentation supporting the configurations identified. The radiated data and documentation presented in this application supports the following additional configurations HePA 850 Mhz ( GMSK 60W / 8PSK 45W) DRX ND / ND2 PCS1900 (GMSK) The above configurations all use the identical platform and are field configurable systems. Nortel wishes to introduce a 60 Watt High Power amplifier, which as per FCC part 2 of the rules requires a new application for equipment authorization be submitted. Due to complexity of managing many ID numbers for the same system, Nortel is submitting the new application with test data for the new increased power configurations, and all of the configurations noted above under the existing approvals. Note that the 850 Mhz HePA (power amplifier) has received stand alone certification by their manufacturer Andrew. The PA is certified under FCC ID: S8L-100306HEPA Products Approvals Team Nortel

Introduction This memo provides inputs with regard to the assessments of Health protection and radiation hazards expected from Nortel S8000 and S12000 BTS equipped with high power amplifier HePA, operating in the 1900 Mhz and 850 Mhz band, compliant with the North American requirements (FCC OET Bulletin 65) through calculation as described below. Note: HePA may be configured with Diplexer or 2 ways combiner H2D or 4 ways combiner H4D in the same configurations of S12000 and S8000 BTS. Therefore, the same evaluation may be used for these equipments. 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: Frequency range (MHz) MPE (S, mW/cm²) 30 – 300 0.2 300 – 1500 f/1500 1500 – 12750 1.0 Page 2 b. Radiation of a system The power delivered to the antenna (per PA) is given by P(antenna) (in Watts)= (PA(power)– losses) x G(antenna) Different power amplifier(s) and coupling configuration : • Diplexer : 1 Power Amplifiers (PA) in a sector, PA configured to deliver maximum output power 47.8 dbm (60W) with GMSK modulation, Diplexer loss is 0dB. Therefore power output is : 47,8 dBm • H2D diplexer : 2 Power Amplifiers (PA) in a sector, Pas configured to deliver maximum output power 47.8 dbm (60W) with GMSK modulation. H2D power loss is 3dB. Therefore power output is : 47,8 dBm +3dB (2 Pas) – 3dB (loss)= 47,8dBm • H4D diplexer : 4 Power Amplifiers (PA) in a sector, Pas configured to deliver maximum output power 47.8 dbm (60W) with GMSK modulation. H4D power loss is 7dB. Therefore power output is : 47,8dBm +6dB (4 Pas) –7dB (loss)=46,8dBm • Feeder and jumper losses # 1 dB. • Antenna gain G=18 dBi # 63. 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 and S = 0.57 mW/cm² at the frequency of GSM 850 signal. Note: Calculation is done in the worst case of maximum power radiated. Therefore, the calculation is done in Diplexer or H2D configuration (47,8dBm radiated) with GMSK modulation and for S=0.57 mW/cm². As a consequence, the safe distance approach is with the aforementioned considerations R = 8.7 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 S8000 and S12000 BTS comply 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).
