This report also assesses the site's compliance with FCC OET Bulletin 65; "Guidelines for Human Exposure to Radio -frequency Electromagnetic Fields". 3.1 Site Description: • Site Name: SESEA00180C • Street Address 10032 Edmonds Way Edmonds, WA 98020 • Latitude: 47.7907670 • Longitude: - 122.3682470 • Structure Type Rooftop • Structure Height: 45' AGL • BTS Equipment Location: The BTS Equipment is located on the Main Roof. • Co -Locators/ Other Antennas: CD shows Co -locator antennas. Since no co -locator data was provided, a general antenna configuration was used modeling the Unknown carrier. However, until those details can be confirmed in the Post analysis, (Unknown) was used as an identifier in the report. C/Ls were estimated from the CDs. • Access:I Page 6 of 29 Pramira, Inc • 404 North Berry Street, Brea, CA 92821. 800.678.1169 • Pramira Neiwu�k E+ulu Ilan Si n�pll EleO 3.2 Site Configuration Being Modeled: • This a Rooftop application where Dish Wireless antennas are mounted on the Guyed Tower. • This will be a Three -Sector site with One Active antenna in each sector. • The values of the antennas rad center for all sectors (50') Main Roof Height (44.2'), are based on the CDs. These values must be verified on the site audit for the post study. • Each sector supports 5GNR at 600, 700, 1900, 2100, MHz. All LTE supports MIMO. • All technologies were evaluated assuming the maximum number of channels and were running at maximum power 100% of the time.

If Co -Locator antennas exist and the use of "Unknown" as an antenna model that means the specific antenna details could not be secured, generic antennas, frequencies, and Tx powers were used for modeling. The assumptions used are based on past experience with communications carriers. Z-height represents the distance from the nearest walking surface to the Centerline of the antenna.

The FCC guidelines for human exposure to RF electromagnetic fields incorporate two categories of limits; namely "Controlled" (a.k.a. Occupational) and "Uncontrolled" (a.k.a. General Public). The guidelines offer suggested methods for evaluating fixed RF transmitters to ensure that the controlled and uncontrolled limits deemed safe by the FC for human exposure are not exceeded. OET Bulletin 65 recommended guidelines are intended to allow an applicant to "make a reasonably quick determination as to whether a proposed facility is in compliance with the limits." In addition, the guidelines offer alternate supplementary considerations and procedures such as field measurements and more detailed analysis that should be used for multiple emitter situations. These guidelines define RF as emissions in the frequency range of 300 kHz to 100 GHz. The FCC define Maximum Permissible Exposure (MPE) limits within this frequency range based on limits recommended by the National Council on Radiation Protection and Measurement, the Institute of Electrical and Electronics Engineers (IEEE), and by the American National Standards Institute (ANSI). As shown in Table 1 of Appendix A, the averaging time for Occupational/Controlled exposures is 6 minutes, while the averaging time for general population/uncontrolled exposures is 30 minutes. As an illustration of the application of time -averaging to Occupational/Controlled exposure consider the following. The relevant interval for time -averaging for Occupational/Controlled exposures is six minutes. This means, for example, that during any given six -minute period a worker could be exposed to two times the applicable power density limit for three minutes as long as he or she were not exposed at all for the preceding or following three minutes. Similarly, a worker could be exposed at three times the limit for two minutes as long as no exposure occurs during the preceding or subsequent four minutes, and so forth.

Limits for Occupational/ Controlled exposure also apply in situations when an individual is transient through a location where Occupational/ Controlled limits apply provided he or she is made aware of the potential for exposure." For General Population/ Uncontrolled limits, the FCC states that "General Population/ Uncontrolled exposures apply in situations in which the general public may be exposed, or in which persons that are exposed as a consequence of their employment may not fully be aware of the potential for exposure or cannot exercise control over their exposure." For purposes of this analysis, all limits are evaluated against the Power Density limits. Typical guidelines for determining whether Occupational/ Controlled limits can be applied include ensuring the environment (such as a rooftop) as limited/controlled access via locked doors or physical barrier that are preferably controlled by a landlord that is aware of the situation and can inform anyone going through the locked door of the existence of the RF emissions. Such notification/awareness is typically accomplished by means of signage on the door, or other access to the area of concern, as well as signage on or near the antennas. Examples of such signs include the following: Page 23 of 29 Pramira, Inc • 404 North Berry Street, Brea, CA 92821. 800.678.1169 0Pramira —walk —111 Eled TRANSMITTING ANTENNAISI Redo hegancy Iletds beyond this poet MAY EXCEED the FCC General Public exposure Ilmt Obey all posbd 6" and sne reidobnes br worbng in radio �Quency snnrontnenes Call the Dah IOC M 14G&4M JA p— to WWMV witiew tltk P" Sale qt d=sh • AL CAUTION TRANSMITTIK ANTEM%5 Radio kogjmq folds beyond this point MAY UCM Ow FCC Occupabonal 41pii n bilk.

RoofMaster® was developed in 2008 by Waterford Consultants to support compliance assessments performed at single and multi -operator wireless locations throughout North America and has been in service since 2008. Real -world experience in evaluating thousands of base station installations are reflected in the RoofMaster® design approach. This document provides a guide for creating simulations of RF hazard conditions through the characterization of antenna systems and site features and through FCC -specified computational analysis. On any structure, one may encounter antennas installed by wireless service providers, public safety and other FCC -licensed and unlicensed operators. Siting constraints have resulted in diverse and complex environments accessible to people performing a variety of activities around these antennas. RoofMaster® supports the characterization of these locations to convey important information regarding RF sources and accessible areas necessary to evaluate the potential for human exposure to hazardous levels of RF energy. RoofMaster® supports the depiction of communications sites through the display of construction drawing or aerial photography image files as well as providing line drawing tools. These representations are scalable to enable the modeling of any location. RoofMaster® utilizes a three-dimensional spatial framework consisting of a 1000 x 1000 grid with unlimited vertical dimensions necessary for the positioning of antennas and modeling of RF conditions at each grid point throughout the space. Predictive analysis is performed on a study plane at a specified elevation. The subsequent sections of this guide provide the steps necessary to create a site representation and conduct these studies. RoofMaster® employs several power density prediction models based on the computational approaches set forth in the Federal Communications Commission's Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields, OET Bulletin 65. This guideline utilizes several antenna and operational parameters in calculating the power density contributions from each emitter at specified points throughout the study space. RoofMaster® enables antennas to be fully defined in site specific aspects as well as through the use of a library of manufacturer data. The parameters include: Page 25 of 29 Pramira, Inc • 404 North Berry Street, Brea, CA 92821. 800.678.1169 �i Pramira Neiwu�k E+ulu Ilan Si n�pll EleO § Antenna model § Radiation patterns § Aperture length § Gain § Beamwidth § Antenna radiation center § Azimuth § Mechanical down -tilt § Location § Frequency § Power into antenna In OET-65, the Cylindrical Model is presented as an approach to determine the spatially averaged power density in the near field directly in front of an antenna. In order to implement this model in all directions, RoofMaster® utilizes the antenna manufacturer horizontal pattern data. Additionally, RoofMaster® incorporates factors that reduce the power density by the inverse square of horizontal and vertical distance beyond the near field region. Power density is calculated as follows: 360 )PnGHHrY, )pW S= Beannvidth 2 ,TRh CM 2 • S is the spatially averaged power density value • R is the horizontal distance meters to the study point • h is the aperture length in meters • P;,, is power into the antenna input port in Watts RoofMaster® Implementation: • Gx is gain offset to study point as specified in manufacturer horizontal pattern • Pi,, is adjusted by the portion of the antenna aperture in the 0-6 ft vertical study zone • Hr accounts for 1/R2 Far Field roll off which starts at 2*h • Vr accounts for 1/ (vertical distance) 2 roll off from antenna bottom to the top of the 0-6ft study zone (or antenna top to bottom of 0-6ft study zone) Page 26 of 29 Pramira, Inc • 404 North Berry Street, Brea, CA 92821. 800.678.1169 Pramira Horizontal Distance Not to Scale Page 27 of 29 Pramira, Inc • 404 North Berry Street, Brea, CA 92821. 800.678.1169 • Pramira Neiwu�k E+ulu Ilan Si n�pll EleO 9 References FCC (1997).
