Box 11490, Station “H” Ottawa, Ontario K2H 8S2 Canada Subject: Request for Confidentiality FCC ID: TA8AKRC161884-1 IC: 287AB-AS1618841 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 and in accordance to RSP- 100 Section 9.4 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) 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/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 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.

The spurious emissions from the antenna terminal were measured. The transmitter output power was attenuated using an attenuator and the frequency spectrum investigated from 3KHz to 9GHz. The resolution bandwidth of 1MHz was employed for frequency band 3KHz to 9GHz. The spectrum analyzer detector was set to RMS. For MIMO mode configurations, the limit was adjusted with a correction of -6.02dB [10Log(1/4)] by using the Measure and Add 10Log(N) dB technique according to KDB 662911 D01 Multiple Transmitter Output accounting for simultaneous transmission from antenna ports. Then the limit was adjust to -19.02dBm. A.4.3 Measurement limit The power of any emission outside of the authorized operating frequency ranges must be attenuated below the transmitting power (P) by a factor of at least 43 + 10log(P) dB.

For MIMO mode configurations, the limit was adjusted with a correction of -6.02dB [10Log(1/4)] by using the Measure and Add 10Log(N) dB technique according to KDB 662911 D01 Multiple Transmitter Output accounting for simultaneous transmission from antenna ports . Then the limit was adjusted to -19.02dBm. In the 1 MHz bands immediately outside and adjacent to the frequency block, a resolution bandwidth of at least one percent of the emission bandwidth of the fundamental emission of the transmitter may be employed and a RBW of 1MHz for measurements of emissions > 1MHz away from the band edges. The limit was adjusted with -13.01dB [10Log(50/1000)] to compensate for the reduced measurement bandwidth 50KHz for emission more than 1MHz away from the band edges. For MIMO mode, the limit of -32.03dBm was used. Spectrum analyzer detector was set as RMS. A.3.3 Measurement limit The power of any emission outside of the authorized operating frequency ranges must be attenuated below the transmitting power (P) …
