4 EVANS <br /> ENGINEERING <br /> SOLUTIONS <br /> #7 Co-location Capabilities of the Proposed Tower <br /> According to Verizon Wireless, the proposed tower has been designed to accommodate three <br /> future additional carriers for a total of four carriers. Verizon Wireless has stated that it will allow <br /> future cellular antenna arrays to be added above 100 feet by expanding the height of the <br /> monopole by 50 feet. The intent of the co-location provision of the Tower Ordinance is to <br /> encourage other wireless carriers to locate their antennas on the approved tower so as to <br /> minimize the need to construct new tall towers. Since there are several cellular and PCS <br /> providers besides Verizon Wireless, additional providers might consider co-locating at this <br /> proposed site, although this is not guaranteed. In any case, the technical requirements of other <br /> providers cannot be known by Verizon or this consultant. <br /> #8 Conformance to Aviation and Industry Standards <br /> Verizon Wireless has stated in its CUP application documents (SBA's "Site Specific Obstruction <br /> Evaluation Report") that the antenna structure, at 155 feet (including 5-foot lightning rod) does <br /> not exceed federal aviation obstruction standards and would not require the employment of <br /> obstruction lighting. This determination was independently confirmed by this consultant using <br /> the FCC's TOWAIR pre-determination program; however, the findings of TOWAIR, while <br /> informative, are not necessarily conclusive. It is the responsibility of the tower proponent to <br /> exercise due diligence to determine if it must coordinate its structure with the FAA. <br /> The SBA site report also states that there are no AM broadcast transmitters close enough to the <br /> proposed monopole site to require an impact study regarding AM broadcast operations. This <br /> finding has also been verified by this consultant. <br /> Assuming no serious malfunction of either cellular transmitters or public safety radio receivers, <br /> interference to public safety or other RF services is not expected. In any case, all transmitters and <br /> receivers located at common sites should observe good engineering practice with respect to <br /> tower bonding and grounding. <br /> #9 Concerns of Interference to Receivers or Other Electronic Devices <br /> RF emissions from cellular base station towers have not been reported to cause interference to <br /> radio receivers, television sets, phones (wired or wireless), or other consumer electronic devices, <br /> in violation of FCC rules. Unlicensed devices, such as garage door openers and some wireless <br /> devices, are legally not protected from interference by FCC rules. However, even in these cases, <br /> interference is extremely rare because the emitted RF power used by the cell site is relatively <br /> low. Therefore, interference to consumer devices is not expected; even if it occurs, it can easily <br /> be mitigated by means of RF "choking" devices. <br /> Evans Engineering Solutions Communications Consultants 6 <br /> Verizon— Town of Rutland CUP Site Assessment Report <br />
