This is based on the following reasons: This product is intended for use in an Ericsson Radio Base Station (BS) designed and built to state of the art technical specification and implemented with innovative solutions for a highly competitive market. Competition in this market is very intense and therefore the necessity for confidentiality is essential to protect Ericsson IP and trade secrets. Ericsson AB / Ericsson Canada confidential exhibits / documentation contains Ericsson company proprietary information (or that of our suppliers and contractors), in addition to trade secrets and proprietary information that are not intended for public disclosure. The confidential exhibits in this application are provided exclusively for the radio authorization submission and approval process and therefore need to be protected from public disclosure. Ericsson AB / Ericsson Canada has invested considerable time and materials in research and development to produce the referenced product. Disclosure of the permanently confidential portions of this application to competitors would not only give them significant competitive advantages in developing similar products, but would also disclose successful implementation of unpublished, leading edge technology and solutions developed and / or implemented by Ericsson. The Confidential Exhibits listed below contain highly technical and confidential information about our product and are only available to trained and authorized service personnel. This equipment is not available to be sold to the general public, (nor is it a consumer product) and can only be accessed and installed by trained service personnel under NDA (Non-Disclosure Agreement) with Ericsson. In addition, this product is installed in restricted access areas and is only serviceable by the licensee or his designated technicians. Confidential product information can be found in, but not necessarily limited to, internal photos, block diagrams, schematics diagrams, and parts lists as well as certain documents, such as the user’s manuals. 2 (2) Prepared (also subject responsible if other) No. Denis Lalonde TA8AKRY901515-3 Approved Checked Date Rev Reference June 22, 2022 PA1 KRY 901 515/3 RDS DOT 44Kr B77D - Request for confidentiality list: • Exhibit 04 Block diagram • Exhibit 05 Schematics • Exhibit 08 User Manuals • Exhibit 09 Internal Photographs • Exhibit 10 Bill of Materials • Exhibit 12 Operational and Technical Descriptions Should additional information be required, please contact the undersigned: .....................................................................

The full report provides a complete description of all test details and results. 3 (9) GFTL-22:000819 Uen, Rev A, 2022-06-03 2 General information The purpose of the tests was to verify that the EUT is in compliance with the appropriate RF exposure standards, recommendations and limits applicable in the USA [1]–[3]. Compliance is demonstrated by showing that the EUT meets the test exemption criteria specified in [3] at a minimum test separation distance of 20 cm. The details of the analysis are presented in Section 4. It should be noted that the test results presented in this test report are valid for the frequency range and for the antenna properties specified in Table 1, in addition to the power level, the power tolerance and TDD downlink duty cycle specified in Table 2. These data, together with information on the physical separation of the antennas were supplied by the client and may affect the validity of the results. The test results were determined for Dot 44Kr B77D (equipped with internal antennas) and are also applicable for Dot 41Kr B77D connected to external antennas provided that the antenna gain for each branch is equal to or smaller than 5.4 dBi and that the minimum distance between antennas remains equal or larger than 75 mm. Proposed EMF health and safety information for inclusion in the Customer Product Information (CPI) is provided in Appendices A and B. 3 Equipment under test Table 1 summarizes the technical data for the EUT. Photographs and drawing of the EUT are presented in Appendix C. Table 1 Technical data for the EUT.

The minimum test separation distance for which the equipment is 2 Conservative measure of the total maximum possible output power level delivered to the antennas including losses, tolerances, and maximum TDD DL duty cycle. 4 (9) GFTL-22:000819 Uen, Rev A, 2022-06-03 shown to comply with the exposure limits must be clearly provided in the operating and installation instructions. A minimum test separation distance of at least 20 cm is required between the device and nearby persons to apply mobile device exposure limits. 4.1 Single antenna The effective radiated power (ERP) for each of the four antenna branches (including output power tolerance and TDD DL duty cycle) is calculated in Table 3 based on the EUT data provided by the client and reported in Table 1 and Table 2. Table 3 also specifies the ERP threshold derived by means of the SAR-based exemption threshold specified in [3] 3 for a minimum test separation distance of 20 cm and applicable in the frequency range of …
