Purpose: To demonstrate compliance with United States, Canada, Australia and/or European Union RF Exposure requirements for Mobile Equipment (devices used >20cm from the body), where MPE measurements apply. Device and Antenna Operating Configuration: Device operating at maximum output power with continuous transmission of modulated data. Test Procedure: This equipment is evaluated in accordance with the guidelines set forth in KDB 447498 & ANSI C95.1 for the US, Health Canada Safety Code 6 & RSS 102 for Canada, ARPANSA RPS3 for AU and EN 62479 or EN 62311 for EU. Other Considerations: Report considers stand-alone configuration only. RF Exposure limits are calculated at the mid-point of each operating band Referenced Test Reports: The following test reports were referenced in conjunction with this assessment: 102206-2 102206-4 102206-8 102206-11 Page 2 of 13 Report No: 102206-29

Summary: MPE Measurement Results: Equipment demonstrating compliance with MPE measurement have been evaluated for use under mobile RF exposure configurations as identified herein. Additional configurations including collocation or simultaneous transmission with other transmitters (including necessary separation distances) are subject to further assessment. It is assumed that the manufacturer shall design the equipment such that the minimum separation distance of 20cm (or greater, as listed above) is met or that the manufacturer provides a protection guide (e.g. installation instructions) to the end user such that the antenna(s) may be installed in accordance with the manufacturer’s instructions in such a manor to maintain the minimum separation distance. General Comments: The absorption and distribution of Electromagnetic energy in the body is a very complex phenomena that depends on the mass, shape and physiological condition of the body; the orientation of the body with respect to the fields; and, the electrical properties of the body and the environment. Variables that may play a substantial role in possible biological effects are those that characterize the environment (including but not limited to: ambient temperature, air velocity, relative humidity and body insulation); and those that characterize the individual (including but not limited to: age, gender, activity level and existing debilitation or disease). Because innumerable factors may interact to determine specific biological effects of exposure to electromagnetic fields, any protection guide should consider both intended and unintended operational environments and provide guidance for installation and use of the product such that proper separation distances can be maintained.

APPENDIX A - Assessment Procedure TEST CONFIGURATION The EUT antenna is placed in a configuration typical of normal installation. Where antenna mounting is required, non-conductive materials are used for support structures. In the special case of magnetically mounted vehicle antennas, a reference ground plane is used to simulate actual installation. In order to limit external interference effects, the test is performed in a semi-anechoic chamber. The EUT equipment is setup in a configuration representative of normal use. Support equipment for the measurement instruments are located outside of the testing area. TEST PROCEDURE Measurements are performed using a broadband detector with three orthogonal measurement axes. Values recorded are RMS based on the maximum measurements. To determine the direction of the maximum measurement, the detector is moved throughout the RF field generated by the transmit antenna. The detector is positioned at a minimum of 12 radials and at varying distances from the antenna along each radial. The area of maximum RF energy determined during preliminary investigation shall be used for the remainder of the tests. In the case where a transmitter may have multiple frequency bands, the preliminary investigation shall be repeated for each band. For time varying fields, the appropriate averaging time is used. For spatially uniform fields, the measurement height is selected based on maximum preliminary measurements. For spatially non-uniform fields (e.g. distances close to a magnetically mounted vehicle antenna), spatial averaging may be performed. The method for performing spatially averaged measurements is as follows: 1. Determine the direction of the maximum measurement. 2. At a specific distance measure vertically from the floor 5 points comprising a linear cross section of an adult human body, beginning at 0.2m and at each 40cm up to 1.8m. 3. Calculate the average of the measurements and compare with the established limit. Since the applicable limits exist in several different measurement units, the following outlines the most common calculations used for determining the spatially averaged field. Case 1: Where limits are applied in electric field strength (V/m), the spatially averaged electric field strength along a grid of n points is calculated using: 1 1 n 2 E    Ei2   n i 1  Case 2: Where limits are applied in units of power density (mW/cm2), assuming measurements are made in the far field, where the E and H vectors are mutually orthogonal, power density is first calculated using: E2 S 3770 And the spatially averaged power density along a grid of n points is calculated using: 1 n S  Si n i 1 Page 5 of 13 Report No: 102206-29

The following diagram is an example of the grid used to perform local measurements for RF exposure evaluation over a whole-body spatial average. 1 The following diagram is an example of the setup used for most tests, excluding magnetically mounted vehicle antennas. 1 Source: IC GL-01 Page 6 of 13 Report No: 102206-29

The following diagram is an example of the setup used for vehicle-mounted antennas. In the case where vehicle glass mounted antennas are used, this setup shall not apply. The letter X represents the test distance used for RF exposure measurements. The distance X is measured from the phase center of the transmitting antenna to the volumetric center of the measurement instrument. In order to more accurately simulate normal installation, the antenna ground plane is not bonded to the ground reference plane. The transmitting antenna is placed in the center of the antenna ground plane. Page 7 of 13 Report No: 102206-29
