Ericsson AB requests a Grant of Certification (Type Acceptance) for the above mentioned FCC Identifier. The radio operates in the broadband radio service band as per 47 CFR Part 27. This Permissive Change request for this radio (AIR 6488 B41M) is to support NR 70 MHz . This radio (AIR 6488 B41M) is designed for use in NR and LTE mobile telephone system. This radio operates in Band 41M, the transmitter and the receiver from 2590 MHz to 2690 MHz. It supports channel bandwidths of 20, 30, 40, 50, 60, 80, 90 and 100 MHz for NR. It also supports split mode of LTE and NR, in which the channel bandwidth of LTE is 20 MHz and the channel bandwidth of NR is 40MHz. The radio supports modulation types of QPSK, 64QAM and 256QAM for NR, and modulation types of QPSK, 16QAM, 64QAM and 256QAM for LTE. The radio has the ability to be used in a RBS system configured for 3GPP FD-MIMO and beamforming technologies as an Advanced Antenna System. The radio has 64 TX/RX ports. In split mode of LTE and NR, 32 TX/RX ports will work for LTE and the other 32 TX/

RX ports for NR. This radio will in normal mode of NR operates at a maximum power of 1.25W for channel bandwidth of 20 MHz, 1.875W for 30 MHz, 2.5W for 40 MHz and 3.125W for 50, 60, 70, 80, 90,100 MHz per port at the transceiver array boundary (TAB) connector. This radio will in split mode of LTE and NR operates at a maximum power of 3.125W for LTE per port and a maximum power of 2.5W for NR per port at the transceiver array boundary (TAB) connector. The Exhibit 8 user manuals submitted with this application is generic and may cover multiple products. This application is only valid for the model specified in the Exhibit 12 circuit description. 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.

Subject: Request for Confidentiality

FCC ID: TA8AKRD901155

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 Commission’s Rules for FCC.

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) compared to the previous

BS/RU/RRU/RD, the listed Exhibits/Items need to be protected from disclosure to our competitors in the

industry. As the FCC 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 user’s manuals. Those

documents can only be accessible by the customers who purchase our BS/RU/RRU/RD and accept the

conditions and therefore are provided with unique information access tools.
