This report summarizes the results of Approval DFQj�MF �,�Q ►��in raintion to relavanr Fc'C RF-EME compliance standards for limiting human exposure 0 Signature to RFriEM8d`reWw This report contains a detailed summary of the RF EME analysis for the site. Case Manager This document addresses the compliance of T-Mobile's proposed transmitting facilities independently at the site. The Maximum Emissions Value is 727.8000% of the FCC's general public limit (145.5600% 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 727.80 percent of the FCC's general public limit (145.56 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 9 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. 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 CorMunit fj�e&9 e3T 0MMtment CRJ&IPA,Lioq&4YMIqj@OmpCe"peql.n€he proposed T-Mobile Wireless antenna rooftop facility located at CUPERTINO 21760 SteveAsPERWBSulevard in Cupertino, California using the equipment information listed below. Case # All calcuDtRQ2()gE@e0Wormed per the specifications under FCC OET 65. Because of the short waveler NcdioRQmwxices, the antennas require line -of -site paths for good propagation, and are typ�i`c'al�ll installed a distance above ground level.

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. There are no collocated carriers on the rooftop. 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 Ca Ap Ap Sig Cor�rRunityTiYMR40pnA?%�gfirKypntory Planning Division — Cupertino o J r Antenna Number n.LLpP�D�lI1 Antenna n-_. a Model Height(ft) Above Nearest Walking Surface Azimuth (°) Technology Frequency Band Power Per Channel (W) Number of Channels ERP (W) I ApOigation P 11 umber( 1A20 A 6.0 0 LTE 700 MHz 30 1 442 rav i Body: DIrei for I APXVAARR 18 43-U- Staff NA20 6.0 0 LTE 600 MHz 30 1 403 rpv A i Date f 10/09/1 APXVAARRI8_43-U- 0 GSM/UMTS PCs - 1900 MHz 30 2 1229 natu e Erick Serrano 1 APXVAARR18_43-U- A I 6.0 0 LTE AWS - 2100 MHz 60 2 2888 RFlase Ua gaL NA20 APXVAARR 18 43-U- B I RFS NA20 6.0 140 LTE 700 MHz 30 1 442 APXVAARR 18_43-U- B I RFS NA20 6.0 140 LTE 600 MHz 30 1 403 APXVAARR 18_43-U- B I RFS NA20 6.0 140 GSM/UMTS PCs - 1900 MHz 30 2 1229 APXVAARR 18 43-U- B I RFS NA20 6.0 140 1 LTE AWS - 2100 MHz 60 2 2888 APXVAARR 18 43-U- C I RFS NA20 6.0 240 LTE 700 MHz 30 1 442 APXVAARR 18 43-U- C I RFS NA20 6.0 240 LTE 600 MHz 30 1 403 APXVAARR 18_43-U- C I RFS NA20 6.0 240 GSM/UMTS PCs - 1900 MHz 30 2 1229 APXVAARR 18_43-U- C I RFS NA20 6.0 240 LTE AWS - 2100 MHz 60 2 2888 • This table contains an inventory of only T-Mobile Antennas and Power Values.

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. 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 27.30% of the FCC's general public limit (5.46% 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 100% threshold standard per the federal government. EBI'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 9 feet of T-Mobile's Sector A and 8 feet of T-Mobile's Sector B and 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 I foot of T-Mobile's Sector B 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 Attachment Community Development Department �I Planning Division — Cupertino ERTINO APPROVED 3se# DIR-2019-005 Application Number(s) 3pri opri gna % FCC Public Exposure Limit ■ 500 < Exposure Level ❑ 100 < Exposure Level 5 500 ■ ExpowreLevels 100 and Recommended Signage 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.

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 1000 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.
