Members of the Planning Board Town of Ithaca 215 North Tioga Street Ithaca, NY, 14850 RE: Evidence from a licensed engineer that smaller and shorter towers will not achieve the necessary coverage goals sought by VZW (not smaller towers on the same property, but smaller/shorter facilities in the area, possibly collocated on existing structures and/or telephone poles, and the like) Honorable Members of the Town of Ithaca Planning Board: During the PB meeting held on Oct 1st, 2024, some members of the public raised the suggestion of shorter towers located elsewhere, instead of a 134’ tall monopole at 111 Wiedmaier Court. Verizon RF engineering team reviewed these suggestions and concluded that shorter towers (or smaller cells) will fail to achieve the site objectives for the following reasons. • The proposed “Sunny View” site is proposed as a macro telecommunication tower since it is designed to be the backbone (anchor) network solution throughout the area it is intended to provide coverage. When compared with a small cell site alternative (or a cluster of smaller cell sites) in a rural area like this which is subject to significant terrain, large geographic coverage area and laced with foliage challenges the small cell coverage capability is unsuitable. Small cells or smaller macro tower sites would be blocked (shadowed) by terrain and foliage rendering them ineffective. This macro tower site will provide the requisite coverage throughout the objective area, contiguous for several miles, making this solution appropriate for the challenging morphology and less densely populated area. Small cell sites are intended to cover a much smaller area, typically a few hundred feet, and are better suited for dense urban environments or specific locations where their smaller footprint can be engineered to provide hotspot coverage or capacity enhancements (complimentary to the area macro site). Macro sites have the structural capability of deploying Verizon’s numerous licensed bands of spectrum through the more capable macro antennas where small cells are limited in antenna size/number/weight not to mention small cells do not offer the necessary physical space to house all of the equipment needed to support this proposed site’s radio configuration. • A macro site must be installed on a strategically and centrally located tall structure (relative to the objective area) for several key reasons. For instance, LOS (Line Of Sight), towers that are above area “clutter” provide a clear line of sight between the antenna and the devices it serves, which is crucial for maintaining adequate and reliable signals, especially for higher frequency bands including but not limited to AWS, PCS, and C-band. These higher frequency bands have shorter wavelengths but wider bandwidth capabilities. Another reason is coverage footprint (service area). As antenna height increases so does the site’s coverage capabilities. In order for the proposed site to be effective throughout this objective area the antennas must be located above area clutter in order to overcome physical obstructions such as buildings, trees, and terrain features. By strategically locating the antenna above these obstacles, the signal can propagate without excessive and unwanted signal degradation allowing the site to serve the users as intended. In this case Verizon Wireless RF has determined that one centrally located solution of adequate elevation (130’ ACL at the proposed location) will resolve the identified area problems and minimize community impact (minimize tower proliferation). Previously discussed alternatives of lowering the antenna centerline will result with the site being incapable of solving the area problems. Further discussion of adding additional smaller sites resulting with a higher number of towers in this area is counterintuitive to minimizing community impact and results with multiple sites that do not achieve objectives perpetuating the need for even more sites and greater community impact. • In summary an alternative deployment located on new or existing smaller structures (including utility poles) is impractical as they have too many limitations including but not limited to low antenna centerline, equipment space/size/power constraints, and structural limitations causing gaps in coverage and inability to achieve objectives stated in the RF Justification. Simply put utility poles or other smaller towers or structures are not capable of supporting the equipment and coverage requirements needed for this project area. In view of the aforementioned details, in order for the “Sunny View” facility to successfully achieve the necessary RF objectives, it must be a macro site on a new 134’ tall monopole (130’ ACL) instead of a small cell site (or a cluster of smaller cell sites) on new or existing structures. This macro solution will provide adequate and reliable coverage to the southern portion of the Town of Ithaca known as the “Sunny View” project area. Thank you for your consideration.
