(dba EBI Consulting) has been contracted by T-Mobile to conduct radio frequency electromagnetic (RF-EME) modeling for T-Mobile Site SD06367A located at 6994 El Camino Real in Carlsbad, California to determine RF-EME exposure levels from proposed T-Mobile wireless communications equipment at this site. As described in detail in Appendix B of this report, the Federal Communications Commission (FCC) has developed Maximum Permissible Exposure (MPE) Limits for general public exposures and occupational exposures. This report summarizes the results of RF-EME modeling in relation to relevant FCC RF-EME compliance standards for limiting human exposure to RF- EME fields. This report contains a detailed summary of the RF EME analysis for the site. This document addresses the compliance of T-Mobile's proposed transmitting facilities independently and in relation to all existing collocated facilities at the site. The Maximum Composite Emissions Value is 1444.4000% of the FCC's general public limit (288.8800% of the FCC's occupational limit) at the main roof level. The proposed site will be compliant with Federal regulations regarding (radio frequency) RF Emissions with the installation of the mitigation measures. At the nearest walking/working surfaces to the T-Mobile antennas on the rooftop and ground, the maximum power density generated by the T-Mobile antennas is approximately 892.90 percent of the FCC' s general public limit ( 178.58 percent of the FCC's occupational limit). Based on worst-case predictive modeling, the worst-case emitted power density may exceed the FCC's general public limit within approximately 12 feet of T-Mobile's proposed antennas at the main roof level. Modeling also indicates that the worst-case emitted power density may exceed the FCC's occupational limit within approximately 2 feet of T-Mobile's proposed antennas at the main roof level. There are predicted exposures above the general public limit seen within approximately 9 feet in front of the other carrier antennas. Signage is recommended at the site as presented in Attachment I. Posting of the signage and installation of other markings brings the site into compliance with FCC rules and regulations. 3 EBI Consulting ♦ 21 B Street ♦ Burlington, MA 01803 ♦ 1.800.786.2346 2.0 MPE Calculations Calculations were completed for the proposed T-Mobile Wireless antenna rooftop facility located at 6994 El Camino Real in Carlsbad, California using the equipment information listed below. All calculations were performed per the specifications under FCC OET 65. Because of the short wavelength of PCS services, the antennas require line-of-site paths for good propagation, and are typically installed a distance above ground level. Antennas are constructed to concentrate energy towards the horizon, with as little energy as possible scattered towards the ground or the sky. This design, combined with the low power of PCS facilities, generally results in no possibility for exposure to approach Maximum Permissible Exposure (MPE) levels, with the exception of in areas in the immediate vicinity of the antennas. In accordance with T-Mobile's RF Exposure policy, EBI performed theoretical modeling using RoofView® software to estimate the worst-case power density at the site rooftop and ground-level resulting from operation of the antennas. For this report, EBI utilized antenna and power data provided by T-Mobile and compared the resultant worst-case MPE levels to the FCC's occupational/controlled exposure limits outlined in OET Bulletin 65. EBI has performed theoretical worst case modeling using RoofView® to estimate the maximum potential power density from each proposed antenna based on worst-case assumptions for the number of antennas and power. All radios at the proposed installation were considered to be running at full power and were uncombined in their RF transmission paths per carrier prescribed configuration. The assumptions used in the modeling are based upon information provided by T-Mobile in the supplied drawings and known configuration values information gathered from other sources to approximate each additional carrier's contribution. Based on drawings and aerial photography review, unknown carrier wireless antennas are also present on the rooftop. These antennas were included in the modeling analysis. The Maximum Emissions Value for the additional carriers included in the modeling is 1444.30% of the FCC general public limit (288.86% of the FCC occupational limit) at the rooftop or ground walking/working surfaces. The data for all T-Mobile antennas used in this analysis is shown in Section 3.0. Actual antenna gains for each antenna were used per manufacturer's specifications. All calculations were done with respect to uncontrolled and general public threshold limits. 4 EBI Consulting ♦ 21 B Street ♦ Burlington, MA 01803 • 1.800.786.2346 Sect.or A A A A 8 8 8 8 C C C C 3.0 T-Mobile Antenna Inventory An11111111 Heip(ft) PowerPer Number of Number Anterwa Make Antenna Model Above Nearest Azimuth(") Technology frequency Band Channel (W) Channels W....,,Surface I Ericsson Alr21 1.7 350 GSM/UMTS PCS-1900 MHz 30 2 2 Commscope FFHH-65A-R3 1.0 350 LTE 600 MHz 30 I 2 Commscope FFHH-65A-R◄ 1.0 350 LTE 700 MHz 30 I 3 Ericsson Air 21 2.7 350 LTE AWS -2100 MHz 60 2 I Ericsson Air21 19.7 90 GSM/UMTS PCS -1900 MHz 30 2 APXVAARRl8_ ◄3-U- 2 RFS NA20 19.0 90 LTE 600 MHz 30 I APXVAARRl8_◄3-U- 2 RFS NA20 19.0 90 LTE 700 MHz 30 I 3 Ericsson Air 21 19.7 90 LTE AWS-2100 MHz 60 2 I Commscope FFHH-65A-R3 1.0 220 LTE 600 MHz 30 I I Commscope FFHH-65A-R◄ 1.0 220 LTE 700 MHz 30 I 2 Ericsson Air21 2.7 220 GSM/UMTS PCS -1900 MHz 30 2 3 Ericsson Air21 1.7 220 LTE AWS -2100 MHz 60 2 • This table contains an inventory of only T-Mobile Antennas and Power Values.

Based on predictive modeling, the worst-case emitted power density may exceed the FCC's general public limit within approximately 12 feet of T-Mobile's proposed antennas at the main roof level. Modeling also indicates that the worst-case emitted power density may exceed the FCC's occupational limit within approximately 2 feet of T-Mobile's proposed antennas at the main roof level. There are predicted exposures seen within approximately 9 feet in front of the other carrier antennas. Installation of mitigation measures will bring the proposed site into compliance. Based on drawings and aerial photography review, unknown carrier wireless antennas are also present on the rooftop. These antennas were included in the modeling analysis. The anticipated maximum contribution from each sector of the proposed T-Mobile facility is 892.9000% of the allowable FCC established general public limit ( 178.5800% of the FCC occupational limit). This was determined through calculations along a radial from each sector taking full power values into account as well as actual vertical plane antenna gain values per the manufacturers supplied specifications for gain. The anticipated maximum composite MPE value for this site is 1444.4% of the allowable FCC established general public limit (288.88% of the FCC occupational limit). This is based upon worst-case modeling performed on the rooftop and ground taking emissions contributions from all carriers present into account. This value will determine whether the proposed site will be in compliance with regards to electromagnetic emissions. Based on worst-case predictive modeling, there are no areas at ground level related to the proposed antennas that exceed the FCC's occupational or general public exposure limits at this site. At ground level, the maximum power density generated by the antennas is approximately 11.20% of the FCC's general public limit (2.24% of the FCC's occupational limit). A site is considered out of compliance with FCC regulations if there are areas that exceed the FCC exposure limits and there are no RF hazard mitigation measures in place. Any carrier which has an installation that contributes more than 5% of the applicable MPE must participate in mitigating these RF hazards. For this facility, the composite values calculated were above the allowable I 00% threshold standard per the federal government. EBl's modeling indicates that there are areas in front of the T-Mobile antennas at the rooftop level that exceed the FCC standards for general public and occupational exposure. Based on worst-case predictive modeling, the worst-case emitted power density may exceed the FCC's general public limit within approximately 12 feet of T-Mobile's Sector A antennas, and 7 feet of Sector C antennas at the main roof level. Modeling also indicates that the worst-case emitted power density may exceed the FCC's occupational limit within approximately 2 feet of T-Mobile's Sector A and C antennas at the main roof level. In order to alert any workers potentially accessing the site, a blue Notice sign and a yellow Guidelines sign are recommended at the first point(s) of access to the rooftop. To reduce the risk of exposure and/or injury, EBI recommends that access to the rooftop or areas associated with the active antenna installation be restricted and secured where possible. Caution and/or Warning signage is recommended at the site as presented in the Signage Plan -Attachment I. When Warning signs are required, other markings such as painted striping, chains, stanchions, or fencing may also be used to identify the perimeter of each Safety Zone. 6 EBI Consulting• 21 B Street ♦ Burlington, MA 01803 ♦ 1.800.786.2346 Post at Roof Access Points 1:111111 (<••>)) ~-~- % FCC Public Exposure Limit ■ 500 < Exposure Lewi □ 100 < Exposure Lewi s 500 ■ Exposure Lewi s 100 Hi 8' 4' 0 16' ------When Warning signs are required, other markings such as painted striping. chains, stanchions, or fencing may also be used to identify the perimeter of each Safety Zone. *For Clarity, Other Carrier Antennas are Not Labeled. ■ ■ T-Mobile Antennas Other Carrier Antennas Sign Sign Count Description Posting Instructions l~l•H!I Blue Notice Sign Used to notify individuals they are (<i>) entering an area where the power Securely post at all access points to the site I density emitted from transmitting in a manner conspicuous to all individuals =--~=~ antennas may exceed the FCC's MPE entering thereon. ------limit for the general public or ..... occupational exposures.

EBI Consulting Appendix B: Federal Communications Commission (FCC) Requirements 13 EBI Consulting ♦ 21 B Street ♦ Burlington, MA 01803 ♦ 1.800.786.2346 All information used in this report was analyzed as a percentage of current Maximum Permissible Exposure (% MPE) as listed in the FCC OET Bulletin 65 Edition 97-0 I and ANSI/IEEE Std C95. I. The FCC regulates Maximum Permissible Exposure in units of microwatts per square centimeter (µW/cm2). The number of µW/cm2 calculated at each sample point is called the power density. The exposure limit for power density varies depending upon the frequencies being utilized. Wireless Carriers and Paging Services use different frequency bands each with different exposure limits, therefore it is necessary to report results and limits in terms of percent MPE rather than power density. All results were compared to the FCC (Federal Communications Commission) radio frequency exposure rules, 47 CFR I.I 307(b)( I) -(b)(3), to determine compliance with the Maximum Permissible Exposure (MPE) limits for General Population/Uncontrolled environments as defined below. General population/uncontrolled exposure limits apply to situations in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Therefore, members of the general public would always be considered under this category when exposure is not employment related, for example, in the case of a telecommunications tower that exposes persons in a nearby residential area. Public exposure to radio frequencies is regulated and enforced in units of microwatts per square centimeter (µW/cm2). The general population exposure limit for the 700 and 800 MHz Bands is 467 µW/cm2 and 567 µW/cm2 respectively, and the general population exposure limit for the PCS and AWS bands is I 000 µW/cm2• Because each carrier will be using different frequency bands, and each frequency band has different exposure limits, it is necessary to report percent of MPE rather than power density. Occupational/controlled exposure limits apply to situations in which persons are exposed as a consequence of their employment and in which those persons who are exposed have been made fully aware of the potential for exposure and can exercise control over their exposure. Occupational/controlled exposure limits also apply where exposure is of a transient nature as a result of incidental passage through a location where exposure levels may be above general population/uncontrolled limits (see below), as long as the exposed person has been made fully aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other appropriate means. A site is considered out of compliance with FCC regulations if there are areas that exceed the FCC exposure limits and there are no RF hazard mitigation measures in place. Any carrier which has an installation that contributes more than 5% of the applicable MPE must participate in mitigating these RF hazards.
