Federal Communications Commission Authorization and Evaluation Division Date: February 3, 2021 Confidentiality Request for: FCC ID: VBNAHDB-01 To Whom It May Concern, Pursuant to FCC 47 CRF 0.457(d) and 0.459, Section 10, Nokia Solutions and Networks requests that a part of the subject FCC and/or IC application listed below be held permanently confidential and permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. • Exhibit 5 Operating Description • Exhibit 6 Block Diagram • Exhibit 7 Complete Circuit Diagrams • Exhibit 8 Instruction Book • Exhibit 9 Internal Photographs • Exhibit 14 Parts List Confidentiality of the User Manual is maintained by requiring that any party that is supplied a user manual must first sign a non-disclosure agreement. Currently only cellular system operators have access to these manuals. Internal photos are kept confidential by virtue of the fact that the end product is a non- consumer product, certified and housed in a sealed enclosure, and is only accessible by trained /approved maintenance personnel. Further, the Applicant has spent substantial effort in developing this product, some aspects of which are deemed to be trade secret and proprietary. Having the subject information easily available to our competitors in this market would negate the advantage we have achieved by developing this product. Not protecting the details of the design will result in financial hardship.

Section 1.1310 Radio Frequency Radiation Exposure Limits The criteria listed in Table 1 shall be used to evaluate the environmental impact of human exposure to radiofrequency (RF) radiation as specified in Section 1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of § 2.1093 of this chapter. Further information on evaluating compliance with these limits can be found in the FCC’s OST/OET Bulletin Number 65, ‘‘Evaluating Compliance with FCC-Specified Guidelines for Human Exposure to Radiofrequency Radiation.’’ Response The Nokia AHDB AirScale 2T4R B8 Sub-Band 160W is typically installed on poles or walls in fixed locations. Therefore, the AHDB is neither a portable nor a mobile wireless device. The Nokia AHDB is a 2 port radio head that transmits 40 Watts per port over the B8 spectrum (936.5 – 939.5 MHz). This product supports up to 2x1.4 MHz, and 1x3 MHz LTE carriers, and 3x.2 MHz NBIoT carriers utilizing QPSK, 16 QAM, 64QAM and 256QAM modulation formats. The 2 individual transmit ports are identical in design, rated power and performance. The RF exposure assessment for the overall AHDB will be evaluated separately to ensure the compliance.

All of the transmitters installed in AHDB operate in the frequency range of 936.5 – 939.5 MHz. The maximum power density thus needs to be less than 0.62 mW/cm 2 for general population/uncontrolled environment and 3.11 mW/cm 2 for occupational/controlled environment. Per FCC’s OST/OET Bulletin Number 65, the appropriate EIRP (equivalent or effective isotropically radiated power) limits can be calculated based on the relationship between power density and EIRP, i.e., 2 4R EIRP S   , (1) where S is the power density in mW/cm 2 , R is the distance to the center of radiation of the antenna in cm and EIRP is in mW.

FCC Section 2.1051 - Spurious Emissions at Transmit Antenna Port 5.1 Measurement of Spurious Emissions at Transmit Antenna Port Spurious Emissions at the transmit-antenna terminals were investigated over the frequency range of 10 MHz to beyond the 10th harmonic of the specific transmit band. Carrier Bandwidth is exempt. For this band of operation, the measurements were performed up to 10 GHz. Measurements were made using a Keysight MXA Signal Analyzer. The RF output from the transmitter was reduced (to an amplitude usable by the receivers) using calibrated attenuators. The RF power level was continuously monitored via a coupled RF Power Meter. The required emission limitation is specified as appropriate in 27.53. The measured spurious emission levels were plotted for the frequency range as specified in 2.1057. There were no reportable emissions. Data below documents performance up to 27 GHz. 5.1.1 Spurious Emissions at Tx Port - Plots 5.1.1.1 1-Carrier with NB-IoT Plots (40W) 1.4 + 0.2 MHz BW Test Model 1.1 Modulation QPSK Channel Frequency 938.0MHz TX1 9KHz – 150kHz 150kHz – 30MHz Title 47 Code of Federal Regulations Test Report Global Product Compliance Laboratory Report No.: TR-2020-0173-FCC2-27 Product: AHDB AirScale 2T4R B8 Sub-Band 160W PUBLIC Page 36 of 59 30MHz – 930MHz 949MHz – 9.5GHz 1.4 + 0.2 MHz BW Test Model 1.1 Modulation QPSK Channel Frequency 937.2MHz TX1 9KHz – 150kHz 150kHz – 30MHz 30MHz – 930MHz 949MHz – 9.5GHz Title 47 Code of Federal Regulations Test Report Global Product Compliance Laboratory Report No.: TR-2020-0173-FCC2-27 Product: AHDB AirScale 2T4R B8 Sub-Band 160W PUBLIC Page 37 of 59 5.1.1.2 3-Carrier Plots (40W) (3-Carrier) 1.4 + 0.2 + 0.2 MHz BW Test Model 1.1 Modulation QPSK Channel Frequency 937.2MHz TX1 9KHz – 150kHz 150kHz – 30MHz 30MHz – 930MHz 949MHz – 9.5GHz Title 47 Code of Federal Regulations Test Report Global Product Compliance Laboratory Report No.: TR-2020-0173-FCC2-27 Product: AHDB AirScale 2T4R B8 Sub-Band 160W PUBLIC Page 38 of 59 5.1.1.3 4-Carrier Plots (40W) (4-Carrier) 0.2 + 0.2 + 0.2 + 1.4 MHz BW Test Model 1.1 Modulation QPSK Channel Frequency 938.0MHz TX1 9KHz – 150kHz 150kHz – 30MHz 30MHz – 930MHz 949MHz – 1.8GHz 1.8GHz – 9.5GHz Title 47 Code of Federal Regulations Test Report Global Product Compliance Laboratory Report No.: TR-2020-0173-FCC2-27 Product: AHDB AirScale 2T4R B8 Sub-Band 160W PUBLIC Page 39 of 59 5.1.1.4 NB-IoT Only Plots (40W) (1-Carrier) 0.2 MHz BW Test Model 1.1 Modulation QPSK Channel Frequency 936.7MHz TX1 9KHz – 150kHz 150kHz – 30MHz 30MHz – 930MHz 949MHz – 9.5GHz Title 47 Code of Federal Regulations Test Report Global Product Compliance Laboratory Report No.: TR-2020-0173-FCC2-27 Product: AHDB AirScale 2T4R B8 Sub-Band 160W PUBLIC Page 40 of 59 (1-Carrier) 0.2 MHz BW Test Model 1.1 Modulation QPSK Channel Frequency 939.3MHz TX1 9KHz – 150kHz 150kHz – 30MHz 30MHz – 930MHz 949MHz – 9.5GHz Title 47 Code of Federal Regulations Test Report Global Product Compliance Laboratory Report No.: TR-2020-0173-FCC2-27 Product: AHDB AirScale 2T4R B8 Sub-Band 160W PUBLIC Page 41 of 59 (2-Carrier) 0.2 + 0.2 MHz BW Test Model 1.1 Modulation QPSK Channel Frequency 939.0MHz TX1 9KHz – 150kHz 150kHz – 30MHz 30MHz – 930MHz 949MHz – 9.5GHz Title 47 Code of Federal Regulations Test Report Global Product Compliance Laboratory Report No.: TR-2020-0173-FCC2-27 Product: AHDB AirScale 2T4R B8 Sub-Band 160W PUBLIC Page 42 of 59 Photographs AHDB Unit Radio Testing Setup Title 47 Code of Federal Regulations Test Report Global Product Compliance Laboratory Report No.: TR-2020-0173-FCC2-27 Product: AHDB AirScale 2T4R B8 Sub-Band 160W PUBLIC Page 4…
