Nokia Solutions and Networks Tel: (972) 936-7500 3201 Olympus Blvd Fax: (972) 936-7273 Dallas, Texas 75019 September 10 th , 2024 To whom it may concern: This is a request to hold the internal photos and user manual for FCC ID: VBNAVQQA-01 under long term confidentiality. The transmitter is a Base Station where access is controlled and only available to trained personnel. Please note that the internal photos are being asked to be confidential under the FCC guidelines that this is a non-consumer device (Base Station) and is inaccessible to the general public due to the location of the device and it is only serviceable by the licensee or his designated technicians. The user manual is being requested to be confidential under the FCC guidelines that the manual is very technical and is not provided to the general public. The user manual contains proprietary information required for trained installers to commission the base station. The user manual will be used by the licensee or his designated technicians only. Nokia Solutions and Networks has spent substantial effort in developing this product as a leader in the industry. Having the subject information easily available to competitiors would negate the advantage we have achieved by developing this product. Not protecting the details of design will result in financial hardship. Sincerely, __________________________________________ ______Steve Mitchell__________________ (Signature/Title) (Printed name)

The results of this test pertain only to the sample(s) tested. The specific description is noted in each of the individual sections of the test report supporting this certificate of test. This report reflects only those tests from the referenced standards shown in the certificate of test. It does not include inspection or verification of labels, identification, marking or user information. As indicated in the Statement of Work sent with the quotation, Element’s standard process is to always use the latest published version of the test methods even when earlier versions are cited in the test specification. Issuance of a purchase order was de facto acceptance of this approach. Otherwise, the client would have advised Element in writing of the specific version of the test methods they wanted applied to the subject testing.

AVERAGE POWER - BAND 3.7G TbtTx 2024.05.24.1 WTD.2024.01.16.0 TEST DESCRIPTION Testing was performed using the mode(s) of operation and configuration(s) noted within the report. The individuals and/or the organization requesting the test provided the modes, configurations and settings used to complete the evaluation. The actual test parameters are specified in the test data, this includes items such as investigated frequency range (scanned) and test levels. The testing methods and performance specifications, as well as the test site used for the evaluation are indicated in the test data. The measurement was made using a direct connection between the RF output of the EUT and a spectrum analyzer. The fundamental emission Output Power (maximum average conducted output power) was measured using the channels and modes as called out on the following data sheets. The transmit power was set to its default maximum. RF conducted emissions testing was performed only on one port. The AVQQA antenna ports are essentially electrically identical (the RF power variation between antenna ports is small as shown in this certification testing) and antenna port 1 was selected to perform the testing under this effort as allowed by ANSI C63.26-2015 paragraphs 5.2.5.3, 5.7.2i and 6.4. The RMS average power measurement method for FCC/IC is detailed in section 5.2 of KDB 971168 D01v03r01 and ANSI C63.26-2015 section 5.2.4.4. This method uses trace averaging across the ON and OFF times of the EUT transmissions in the spectrum analyzer channel power function using an RMS detector. Following the measurement a duty cycle correction was applied by adding [10 log (1/D)], where D is the duty cycle in decimal, to the measured power to compute the average power during the actual transmission times. The output power was measured for a single carrier over the carrier channel bandwidth. The power was measured for a single carrier over the channel bandwidth indicated in the table. The total power for multi-port (64x64 MIMO) operation was based upon ANSI C63.26 clauses 6.4.3.1 and 6.4.3.2.4 (10 log N out ). The total output power for Sixty-Four port operation is single power +18.1 dB [i.e. 10*log(64)]. TEST EQUIPMENT Description Manufacturer Model ID Last Cal. Cal.
