               FCC ID: TAB8AKRC161285 — 1
               IC ID: 287AB—AS1612851

               To whom it may concern:
               We, Ericsson AB, hereby request that the Exhibits/Items listed below be withheld from public inspection in
               accordance to 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:

               Ericsson 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 out BS/RU/RRU/RD and accept the conditions and therefore are provided with unique information
               access tools.
