Verizon Wireless' objective is to provide seamless reliable wireless coverage to its users in accordance with the Wireless Communication and Public Safety Act of 1992.' Verizon Wireless is providing the following information in support of its application to the Town of Southold to construct,operate and maintain a wireless telecommunications facility at 1000 Pike Street,Mattituck,NY(the"Proposed Site"). Verizon Wireless has an existing public utility wireless communication facility located at Elijah's Lane&Route 25, Mattituck,with antennas at 78' above ground level(the"Existing Mattituck Site"),which it intends to decommission. As reflected in this report,once the Existing Mattituck Site is decommissioned, there will be a compelling need for the Proposed Site due to a gap in service and an absolute need at that location. As noted on site plans submitted herewith,Verizon Wireless is proposing to install three(3)antermas at 115' above ground level within a new 120' stealth tower. As reflected on the attached propagation maps,the Proposed Site will address Verizon Wireless' service deficiency gap by replacing coverage from the Existing Mattituck Site and adding new additional coverage to other areas which are currently experiencing service deficiencies as well. As a result, the current level of coverage/services offered to the residence,visitors,and business associates relying on wireless service in the Town will be significantly improved.. 2.0 Mobile Communications System Design 2.1 System Considerations Mobile telephony is a method of communication by radio consisting of mobile units,either mounted in vehicles or hand-held,that transmits to and receives signals from fixed base stations(cell sites.) Base stations(cell sites)communicate with mobile wireless devices by sending and receiving signals within a small geographic area. The cell site in turn connects the mobile device to the landline telephone network. The cell sites are designed to cover a small geographic area because mobile telephony devices utilize low power.In addition,the frequencies licensed by the FCC are significantly weakened by obstructions,such as terrain,foliage and buildings which can make the coverage irregular and unreliable. Therefore,it is necessary to locate cell sites at suitable locations and heights in order to provide a seamless and reliable grade of service to the public. Seamless,reliable coverage provides users with the ability to successfully originate receive and maintain quality calls throughout a service area. Overlapping coverage is required for users to be able to move throughout the service area and reliably"hand-off' between cells to maintain uninterrupted calls. As a customer making a call in the vicinity of a cell site moves about and begins to move further away from the cell site,the coverage from that cell site becomes weaker. Unlike broadcast radio,as the customer travels,the call is transferred("handed-off')to an adjacent cell site, if and when that cell site's signal level becomes sufficiently strong. With sufficient overlapping coverage(i.e.,when reliable coverage areas are overlapping),this process is transparent to the user. To establish the necessary distribution of cell sites and help ensure that coverage is seamless and reliable,cell sites are strategically located throughout the licensed coverage area based upon,among other things,network efficiency,topography of the land,and the location of other cell sites. When a significant service deficiency exists, the ability for effective communication is diminished and service can seriously deteriorate in that region. In these conditions, customers experience the inability to make calls, lost calls,partial conversations and/or inaudible conversation. 2.2 System Evaluation System design and evaluation is performed primarily through propagation analysis. Propagation models are widely recognized and accepted in the wireless telecommunications industry as accurate and are routinely utilized. Propagation models simulate how radio waves travel through the environment from one point to another. In order to accurately model the behavior of these radio waves, features in the environment such as elevation of the terrain(e.g. hilly or flat)and the presence of land use classifications must be taken into account. Land use classifications include such designations as builduigs;water,trees, and others. Both elevation and land use data are required to accurately model the real-world behavior of a network because these factors significantly impact radio signal propagation. ' United States Code Title 47,Section 615,amended February 13,2003, C Squared Systems,LLC 2 July 1,2015 All propagation modeling performed for the proposed communications facility utilized high-resolution(30 meter)elevation and land use data. Since signal propagation characteristics differ through open, forested, residential or business areas. Land use classifications are used to account for these differences. The model used in this evaluation employed a sophisticated diffraction based algorithm based on Fresnel-Kirchoff theory that takes into account the terrain and land use along the path from the transmitter to the receiver. A model was generated by collecting empirical data throughout the region and modifying user defined parameters utilized by the algorithm,such that a high degree of correlation between empirical and predicted results is achieved. When that is complete,the resulting propagation model software can predict coverage levels from a transmitter facility given the specific equipment configuration(antenna model,antenna height, power,etc.)of the site in question. 3.0 Existing Network Table 1 below details the existing network site-specific information used to perform the coverage analysis and generate the coverage analysis plots provided herein.

The Existing Mattituck Site is an integral part of the Verizon Wireless network providing the necessary coverage and traffic offload to the area,to ensure a reliable customer experience. Removing the Existing Mattituck Site from the Verizon Wireless network will cause significant network degradation that the Proposed Site will help address. One problem associated with the loss of the Existing Mattituck Site is that there will be significant areas that will no longer have sufficient reliable coverage for users to have the ability to make calls, download email/data, or report emergency situations. The existing coverage shown in Figure B will no longer be valid.

Specifically, once the Existing Mattituck Site is decommissioned there will be a 2.6 square mile net loss of in- vehicle coverage. 1,051 people, 30 businesses and 22.5 miles of roads, including 7.7 miles of major roads,will lose in in-vehicle coverage. In-building coverage will be lost for 2.5 square miles of area, 160 businesses and 1,508 people. A secondary effect to removing the Existing Mattituck Site from the existing network is a traffic capacity overload condition. The ability for a user to make phone calls or use other data services is not only determined by adequate coverage, but also by the available radio resources at each site. This can similarly be related to the number of lanes on a highway and how many vehicles can pass at one time based on how many other vehicles are driving on the road. If there are too many vehicles, there will be a traffic jam that stops travelers from getting to their destination. Similarly, if there are too many wireless phone users, the next attempted call could be blocked. Also,there is an analogous representation of the maximum number of physical lanes that can be added to a highway as there is to the limitation on how many radio resources that can be added to a cell site. The Federal Communications Commission(FCC)has licensed spectrum in the 824-894 MHz(Cellular)region,and the 1850- 1990 MHz(PCS)region. While these frequency bands are capable of supporting the same technologies,there are differences in how the signal propagates for each band. For the higher PCS Frequencies,the wavelength is smaller,and is affected greater by clutter and terrain. As a result,the coverage area for the PCS frequency band is smaller than that of the Cellular frequencies band on the same facility. In the highway vehicle analogy,this can be equated to a driver getting detoured to another road that is smaller C Squared Systems,LLC S July 1,2015 with a slower speed limit. These assumptions are all considered and accounted for in the view of the remaining existing network coverage on Figure C. (All maps are also included in the Appendix at full size to allow for a more detailed inspection). Figure F below shows the search ring for the replacement site.

The solution is to locate the Proposed Site at 1000 Pike Street,Mattituck NY,known and designated as Suffolk County Tax Map District 1000,Section 140,Block 3,Lot 11.1.The proposed Communication Facility will consist of,among other things: a. A site with three(3)panel Antennas mounted within an new +/- 120.0' above ground level(agl)stealth tower,with Antenna centerline height of+/- 115' agl,as more fully described on the site plans submitted herewith; b. An equipment platform concealed in a screening enclosure(the"Equipment Enclosure") located on the rooftop of the existing building; c. Three(3)GPS units mounted to the Equipment Enclosure, as more fully described on the site plans submitted herewith; and d. All other appurtenances,structures, improvements,equipment,devices,cables,conduits and wires related thereto,as more fully described on the site plans submitted herewith. When placed into operation, the site will be operating using 700 MHz, 850 MHz, 1900 MHz and AWS (1700-2100 MHz) frequencies using its licenses from the FCC. The plots and statistics in this RF Report are based on coverage of the 850 MHz frequencies. At-80 dBm,the Proposed Site will increase reliable in-building coverage by 4.1 square miles(the Existing Mattituck Site provides 2.5 sq.mi. and the Proposed Site will provide 6.6 square miles). In addition, at-85 dBm,the Proposed Site will increase reliable in-vehicle coverage by 3.5 square miles(the Existing Mattituck Site provides 2.6 square miles and the Proposed Site will provide 6.1 square miles.). Moreover,at-85 dBm,the Proposed Site will increase reliable in-vehicle coverage to 26.3 miles of additional roadways(the Existing Mattituck Site covers 22.5 miles and the Proposed Site will cover 48.8 miles of additional roadways). (The higher threshold of-75 dBm as specified in the Town Ordinance was not used in these calculations as Verizon Wireless has found -80 dBm to be adequate signal to provide reliable in-building coverage. By providing reliable coverage to a greater geographic area, even more users and businesses will now have the ability to reliably make calls, download email/data, or report emergency situations. For example, at-80 dBm, the Proposed Site will increase the number of people receiving reliable in-building coverage by 2,582 people, an increase of over 240%(the Existing Mattituck Site provides coverage to 1,051 people and the Proposed Site will provide coverage to 3,633 people). In addition, at -85 dBm, the Proposed Site will increase the number of people receiving reliable in-vehicle coverage by 2,185 people (the Existing Mattituck Site provides coverage to 1,508 people and the Proposed Site will provide coverage to 3,693 people). Moreover,at-80 dBm,the Proposed Site will increase the number of businesses receiving reliable in-building coverage by 250 businesses (the Existing Mattituck Site provides coverage to 30 businesses and the Proposed Site will provide coverage to 280 businesses). The below coverage map included as Figure G, illustrates how this Proposed Site will fill in the lost coverage. As you can see from this map,and as earlier quantified in this report,it replaces coverage from the soon to be decommissioned Existing Mattituck Site and provides new coverage to significant areas. Figure H shows the same coverage at the-75 dBm level, as requested by the Town's consultant.

The Proposed Site at 1000 Pike Street,Mattituck,NY will provide reliable replacement coverage due to the loss of the Existing Mattituck Site. In addition,it will provide new coverage to other areas which do not currently have reliable coverage and a compelling need for the Proposed Site. Based on the foregoing data and analysis, it is my professional opinion that: (i) upon decommissioning of Verizon Wireless' Existing Mattituck Site, there will exist a serious deficiency in Verizon Wireless' communications coverage with the Mattituck area; (ii)the Proposed Site is the best suited location in order to provide reliable replacement and additional coverage within the Mattituck area; and(iii)the effectiveness of the Site is confirmed by computer modeling. 7.0 Qualifications and Statement of Certification I am a Radio Frequency Engineer for C Squared Systems,LLC,which has been retained by New York SMSA Limited Partnership d/b/a Verizon Wireless ("Verizon Wireless").
