Users are experiencing a lack of quality wireless service in the area This area has a significant gap in service of approximately 3 miles where quality wireless services are not being provided Significant amount of growth in rural Washington causing more usage on the Wireless Networks Sites surrounding the proposed need capacity offload Many of the users' mobiles are reporting low quality connections for multiple carriers 5 2025 Zoom – proposed site 6 2025 Existing Towers within 2 miles 7 No existing towers within 2 miles of the proposed. 2025 Verizon Sites 2.79 miles 4.38 miles 12.06 miles 9.35 miles 9.59 miles 8 4.57 miles 20252025 Verizon CellMapper Proposed Site The area in the red circle is what the proposed site would impact This area is showing less than outdoor service and no service around the proposed 9 2025 Open SignalVerizonQuality Map This map show mobiles reporting quality of their connections to the network.This is crowdsource data from Verizon users made available by the OpenSignal App: https://www.opensignal.com/apps#section-os-app Green data points show good coverage and red data points show bad coverage and lack of data points show no coverage Notice the lack of coverage reports from mobiles in the area around the proposed. Also note most of the reports show bad coverage. 10 20252025 Verizon Ookla 4GRSRPdata LEGEND Indoor > =-85 dbm In-Vehicle > =-95 dbm On-Street > =-106 dbm The area in red shows the area where the carrier is providing less than in-vehicle and outdoor service, notice the red and orange reports around the proposed Using the legend on the upper right of this slide shows that a mobile needs at least -106dbm RSRP to provide service outdoors. This area islacking coverage where the proposed is located 11 2025 Verizon RSRP Current Coverage Indoor > = -85 dbm In-Vehicle > = -95 dbm On-Street > = -106 dbm LEGEND 12 2025 Verizon RSRPProposed Coverage Indoor > = -85 dbm In-Vehicle > = -95 dbm On-Street > = -106 dbm LEGEND 13 2025 Verizon Best Server Current Coverage 14 2025 Verizon Best ServerProposed Coverage 15 2025 Ionizing vs Non-Ionizing There are two (2) types of Energy/Radio Waves –Ionizing •These are waves that can effect human DNA •Examples are: –Gamma rays –X-Rays •This is one of the reasons the nurse steps out of the room and you wear a lead overcoatwhen you get X-Rays at the dentist. –Non- Ionizing •These are waves do not effect human DNA •Examples are: –Car Radios –Television –Wi-Fi Access points and routers –Bluetooth headsets –Cellphones and Smartphones –Lightbulbs –Wireless Baby Monitors –TV remotes –Absorption of waves is proximity based, the closer you are to the antenna the more non-ionizing energy is absorbed. You will absorb 50% of the FCC’s General Public limit with yoursmartphone next to your ear versus less than 10% of the FCC’s General Public limit from theantennas when you are standing 20’ away from the proposed tower. –The further you walk away from the tower it decreases even more. 16 2025 General Public & Occupational limits The FCC isolated two (2) groups relative to access around wireless antennas The first group is called Occupational –This refers to areas where workers would be allowed (general public cannot access) but the workers wouldnot have knowledge about antennas (An example would be an Air Conditioner Repair Technician). Barriersor signage may be needed to alert the worker when close to the antennas. •Examples are: –Rooftop access behind a locked door –Compound access behind a locked gate –The FCC determined the safe value and then lowered by a factor of 10 and that is the value thewireless carriers use in the studies –The exposure levels are averaged over 6 minutes The second group is called General Public –Uncontrolled access (General Public) •This group is for areas with general public access,the public would not have a knowledge of anantenna being close to them •Examples are: –Sidewalks –Parks –Public accessed buildings –The FCC determined the safe value and then lowered by a factor of 50 and that is the value thewireless carriers use in the studies –The exposure levels are averaged over 30 minutes Compare the value for a tower which is 10mW to the power of a smartphone which is 200mW of power. 17
