This Radio Unit (Radio Dot – RD2242) is designed for use in LTE cellular telephone system. The transmitter will operate from 2110 MHz to 2155 MHz. The receiver circuit supports 1710 MHz to 1755 MHz. It supports channel bandwidths of 5, 10, 15 and 20 MHz for LTE. Radio Unit (RU) supports modulation type QPSK, 16QAM and 64QAM. This Radio Unit operates in the AW S services as per 47 CFR Part 27 subpart C. It meets the requirements of Third Generation Partnership Project (3GPP) for the Universal Mobile Telephone System (UMTS 3G) mobile standard (cellular telephone system) for operation in LTE cellular system. Radio Unit supports spectrum consisting of two or more sub-blocks separated by sub-block gap(s), NCS (None- Contiguous Spectrum). This Radio Unit supports MIMO (Multiple Input Multiple Output) and has the ability to transmit with Multiple Outputs in the same Band with 3GPP MIMO/Spatial multiplexing and beam-forming technologies. Radio Unit will in normal mode operate at a nominal power out of 50 mW per port at the output connectors (2 connectors with up to 50 mW in each connector connected to build in antennas). 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. Section 862. Ericsson AB accept by this request the agreement set out in the document "Bilaga SPCR 125 -Avtal om marknadskontroll för radioutrustning certifierad för USA-marknaden".

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 Commission’s rules and RSP-100 section 6.4 for IC. 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)/Radio Dot (RD) compared to the previous BS/RU/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 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/RD and accept the conditions and therefore are provided with unique information access tools.

The purpose of the tests was to verify that the EUT is in compliance with the appropriate RF exposure standards, recommendations and limits [1] - [4] . 3 Equipment under test Table 1 summarizes the technical data for the EUT.

Table 2 Nominal output power levels. 4 EMF exposure assessments FCC procedures [4] specify exposure assessment methods to verify compliance with EMF exposure limits [1] of mobile devices. A minimum test separation distance of at least 20 cm is required between the device and nearby persons to apply mobile device exposure limits. The test separation distance for which the equipment is shown to comply with the exposure limits must be clearly provided in the operating and installation instructions. 4.1Field strength calculations The maximum gain, ,of the two antennas used is 2.5 dBi (1.7), see Table 1. Assuming correlated transmit signals, the directional gain, , may be taken as 5.5 dBi according to [5]. This is most likely a very conservative assumption given the used transmission modes and antenna topology. The total effective radiated power for the omni-directional antennas is 0.31 W. As a consequence, the categorical exclusion provision of FCC CFR title 47, § 2.1091(c) applies [6] and the minimum test separation distance may be estimated by simple calculations according to plane-wave equivalent conditions [4]. The exposure ratio, , may be conservatively estimated as 2Nominal output powerper port. 3Conservative measure of the total maximum possible output power level delivered to the antennas including losses and tolerances.

Hence, the RF EMF exposure is below the relevant exposure limits [1] for the 20 cm test separation distance. 5 Conclusion The results in Section 4 show that the plane-wave equivalent power density, estimated according to the requirements of FCC [4] and Industry Canada [3], is below the relevant MPE limits [1] at a separation distance of 20 cm between the equipment and any nearby person. Consequently, the EUT is in compliance with the appropriate RF exposure standards and recommendations. 6 References [1…
