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 Commission’s Rules. This due to the following reasons:

DS-CDMA 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) compared to the previous BS/RU, 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.

As out BS are generally installed in restricted places, public access is not possible all thought some types of our BS under certain
circumstances can be installed in an unrestricted place, but the doors on all of our BS’s are key-locked and can be opened only by
authorized personnel. It is therefore individual modules within our BS that should not be revealed to the public.

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 and the RU, 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 and accept the conditions and therefore are provided with unique information access tools.

            EXHIBIT 9 Internal Photos of Radio Unit
            EXHIBIT 4 Block Diagrams
            EXHIBIT 5 Schematic Diagrams
            EXHIBIT 8 Manuals
            EXHIBIT 10 Parts List
            EXHIBIT 12 Technical Circuit Description
