Ericsson AB requests a Class II Permissive Change for the above-mentioned FCC Identifier to support additional NR BW of 25, 30 and 40MHz. The radio operates in the Cellular band as per 47 CFR Part 27. This radio (Radio 4426 B66) is designed for use in SR & MR WCDMA, LTE, NR and NB-IoT cellular telephone system. This FDD radio operates in Band 66. The transmitter operates from 2110 to 2200 MHz and the receiver from 1710 to 1780 MHz in Band 66. It supports channel bandwidths of 3.8-5 MHz for WCDMA, 5, 10, 15, 20 MHz for LTE and 5, 10, 15, 20, 25, 30, 40 MHz for NR. The radio supports modulation types of QPSK, 16QAM and 64QAM for WCDMA, QPSK, 16QAM, 64QAM and 256 QAM for LTE and NR. The radio has the ability to be used in a RBS system configured for 3GPP MIMO and carrier aggregation technologies. This radio will in normal mode operates at a nominal power out of 60 watts at each of the output connector

(4 connectors). This radio will always require a license for transmission. This application is only valid for the model specified in the Exhibit 6 test report. Ericsson AB requests confidentiality under CFR 0.459 according to attached letter. We further certify that the applicant nor any party to the application is subject to a denial of Federal benefits, that includes FCC benefits, pursuant to section 5301 of the Anti-Drug abuse Act of 1988, 21 U.S.C.

Box 11490, Station H Ottawa, Ontario K2H 8S2 Canada Subject: Request for Confidentiality To Whom It May Concern:

We, Ericsson AB, hereby request that the Exhibits/Items listed below be withheld from public inspection in accordance with Sections 0.457 and 0.459 of the Commissions rules for FCC and in accordance with RSP-

100 Section 12.4 for ISED. This due to the following reasons:

This Base Stations (BS) are designed strictly based on the technical specifications of the international project 3GPP (the 3rd Generation Partnership Project). The competition in this field is very intense and a less advanced solution/design could get an unfair advantage by accessing the information as listed below from common domain. As we believe that we have implemented groundbreaking solutions and designs into our recent BS/Radio Unit (RU) / Remote Radio Unit (RRU) / Radio DoT (RD) /Antenna Integrated Radio

(AIR) compared to the previous BS/RU/RRU/RD/AIR, the listed Exhibits/Items need to be protected from disclosure to our competitors in the industry. As the FCC/ISED records have in-depth information and a very wide distribution, we believe that you can understand our concerns. We are strong in our belief that all vendors in the industry need to compete by their own merits. We regard these Exhibits/Items to be our intellectual property and therefore as confidential information. There are advanced technical and design solutions/information in the Exhibits/Items, as mentioned above, that we regard as Ericsson proprietary, with actual and potential patents pending. The information can be advantageous to our competitors as well as sources seeking ways to hack past the built-in security functionality. These solutions or information thereof are not accessible even for our customers or partners unless non-disclosure agreements for particular item(s) have been signed. Confidential product information can be found in, but not necessarily limited to, internal photos of the BS, RU, RRU and RD, block diagrams, schematics diagrams, and parts lists as well as certain documents, such as the users manuals. Those documents can only be accessible by the customers who purchase our BS/RU/RRU/RD/AIR and accept the conditions and therefore are provided with unique information access tools.
