Very high RF exposure levels can be harmful. To protect people against such harmful effects, RF exposure limits with wide safety margins are specified by national and international health authorities. This document explains how to estimate RF exposure levels and compliance distances (minimum separations between antennas and people) for RBS radio configurations and antennas for which such data is not already specified by Ericsson. Note that for typical configurations and recommended antennas, Ericsson provides information and specifies compliance distances as part of the Product Data or Technical Product Description for each specific RBS product. Because it is possible for RF exposure levels to exceed the recommended exposure limits in the areas defined by compliance distances, it is important that RBS antennas are installed so that the general public does not have access to such areas. For configurations and antennas other than those specified by Ericsson, it is necessary to estimate RF exposure levels and specify the requirements for an RBS antenna site. The methods presented here are used to estimate RF exposure levels and the dimensions of the areas from which the general public must be excluded. The methods are also applicable for determining compliance distances for occupational exposure. These and other calculation and measurement methods are described in standards such as EN 50383 and EN 50400, IEEE C95.3 and CEPT ECC/REC/(02)04. 1.1Target Group This document is intended for engineering personnel who create site installation documentation for RBSs used in the following mobile phone systems: • GSM • WCDMA • LTE 1 124 46-EN/LZT 720 0399 Uen E 2008-09-29 Radio Frequency Electromagnetic Fields 2124 46-EN/LZT 720 0399 Uen E 2008-09-29 RF Exposure Limits 2RF Exposure Limits Various national and international RF regulations, safety standards, and recommendations exist that are relevant to RBS RF exposure. The limits defined in these standards are similar and are often based on international guidelines set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), which is recognized by the World Health Organization (WHO). The guidelines have been incorporated in EU Council recommendation 1999/519/EC. The ICNIRP has developed basic restrictions for both occupational and general public exposure to electromagnetic fields that must not be exceeded in any near-field or far-field exposure situation. These restrictions are based directly on established health effects. The Specific Absorption Rate (SAR) is used to specify the basic restrictions in the frequency range 10 MHz to 10 GHz. The SAR is a measure of the rate of RF energy absorption by the body, expressed in units of watts per kilogram of tissue (W/kg). The restrictions are provided to prevent established adverse health effects related to whole-body heat stress and excessive localized tissue heating. Whole-body SAR is averaged over the whole body while localized SAR is defined as the maximum local SAR averaged over any 10 g of tissue. The restrictions, which are summarized in Table 1 on page 3 below, incorporate a safety factor of about 10 for occupational exposure and about 50 for general public exposure. Table 1 ICNIRP Basic Restrictions for Occupational and General Public Exposure Whole-Body SAR (W/kg)Localized SAR 10g (W/kg) (1) Occupational Exposure General Public Exposure Occupational Exposure General Public Exposure 0.40.08102 (1) The limits provided on localized SAR are for head and trunk tissue. Localized SAR limits for limbs are twice as high. Reference levels are provided for the purpose of comparison with exposure quantities in air. In the frequency range 10 MHz to 10 GHz the reference levels are expressed as electric field strength (V/m), magnetic field strength (A/m), and power density (W/m²). The ICNIRP power density reference levels for occupational and general public exposure are summarized in Table 2 on page 4 and Table 3 on page 4 respectively. 3 124 46-EN/LZT 720 0399 Uen E 2008-09-29 Radio Frequency Electromagnetic Fields Table 2 ICNIRP Reference Levels for Occupational Exposure Occupational Reference Levels Expressed as Power Density 10 – 400 MHz400 – 2000 MHz2000 – 10 000 MHz 10 W/m 2 f/40 W/m 2 (1) 50 W/m 2 (1) f = frequency in MHz Table 3 ICNIRP Reference Levels for General Public Exposure General Public Reference Levels Expressed as Power Density 10 – 400 MHz400 – 2000 MHz2000 – 10 000 MHz 2 W/m 2 f/200 W/m 2 (1) 10 W/m 2 (1) f = frequency in MHz The reference levels, which vary according to frequency, have been chosen to prevent the SAR restrictions from being exceeded. This means that additional safety margins have been introduced. The reference levels apply primarily to whole-body far-field exposure situations, whereas they are very conservative for partial-body near-field exposure situations. Compliance with the reference levels will ensure compliance with the basic restriction. If the measured value exceeds the reference level, it does not ne…

The RBS cabinet has already been tested at the factory. The following units are involved when testing the site installation: •RBS main power switch, located outside the cabinet •Distribution power switches on the Internal Distribution Module (IDM) •Operation and Maintenance Terminal (OMT) interface and controls on the Distribution Switch Unit (DXU) For information about the required test equipment, tools and documents, see Section 2 on page 4 . Preconditions Before starting the tests, ensure the following: •A completed test record for Antenna System Tests is available in the Site Installation Documentation •A test record for Site Installation Tests at site is available •Documents Personal Health and Safety Information and System Safety Information have been read •In specific markets where the RBS is supplied without software, the software must be loaded from the OMT according to the instructions given in the document RBS SW Update, using the alternative “New IDB created, using the OMT, is to be used” or “The IDB on flash card is kept”.

Open EXHIBIT 13 1 (1) Prepared (also subject responsible if other) No. EYUEHPA Approved Checked Date Rev Reference CBC/XRV/E [Jeffrey Zhou] 2011-07-06 A WODGKRC161170-4 Federal Communications Commission Authorization & Evaluation Division 7435 Oakland Mills Road Columbia, Maryland 21046 Attention: Equipment Authorization Branch BABT Balfour House Churchfield Road Walton-on-Thames Surrey KT12 2TD May 13, 2011 Subject: Request for Confidentiality To Whom It May Concern: We, Ericsson (China) Communications Company Ltd., 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 3 rd 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 our 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.
