DocuSign Envelope ID:67496B91-FCOD-4188-A6C5-F7496722386E <br /> - 1 Orange County, North Carolina <br /> ORANGE Countywide Radio Communications <br /> COUNTY <br /> NORtIt(AHO INN Interoperability and System Engineering Services <br /> 3.2.5 Proposed System Coverage Analysis (RFP 5.C.4) <br /> 4. Conduct and analyze coverage studies of proposed infrastructure based on multiple <br /> tower sites in order to provide countywide coverage including the potential of new <br /> communications sites, additional"satellite"receiver sites, and/or paging sites. (RFP <br /> 5.C.4) <br /> FE will then model the coverage of the alternative systems. Alternatives will leverage existing sites <br /> and potential new sites to fill coverage gaps. In addition to coverage analyses, FE will also perform <br /> the following for the viable alternatives: <br /> • Coverage Analysis—FE will use FEPerformanceProTM to provide coverage analysis of <br /> each of the viable alternatives as assess how they meet the users' needs. <br /> • Capacity Analysis—FE will use the approved requirements to assess the expected traffic <br /> load of the system. We will then estimate the number of sites and channels required to meet <br /> Orange County's needs. <br /> • Backhaul Analysis—FENetworkTM facilitates backhaul network analysis and design. Our <br /> consultants will assess the backhaul needs for the County based on requirements. As an <br /> option, we can use FENetworkTM to graph individual path profiles for each link or provide a <br /> representation of the entire backhaul network. <br /> • Interference Analysis—As an option, FE will analyze both co-channel interference (also <br /> known as "carrier interference") and adjacent channel interference (interference from a <br /> frequency that is directly adjacent to the desired frequency). Both of these types of <br /> interference can degrade audio quality when a subscriber unit's antenna simultaneously <br /> receives signals broadcast from different sites. FEMitigate IS TM powerful analysis engine can <br /> evaluate either global (all received channels at a given location) or best server(the strongest <br /> received channel at a given location)to provide the information needed to determine a <br /> recommended solution. <br /> • Spectrum Planning—Proper frequency planning is necessary to implement a successful <br /> public safety communications system. FE has provided frequency planning, allocation, <br /> rebanding, narrowbanding, and licensing services to multiple agency levels, from local to <br /> statewide. Our experience covers all public safety frequency bands including VHF, UHF, 700 <br /> MHz, 800 MHz, and 900 MHz, and includes the discovery of available frequencies, <br /> consideration and allocation of FCC rules, ensuring interoperability, and accurate FCC <br /> license filing and coordination. <br /> To help the County establish a future spectrum strategy, FE will analyze spectrum needs <br /> based on the results of the interviews. We will evaluate the potential use of low band, high <br /> band, UHF, 700 and 800 MHz frequencies for use in an upgraded network and indicate if the <br /> County should acquire additional spectrum to meet their anticipated needs. FE will consider <br /> interoperability among public safety and public service agencies who will use the new <br /> network, interoperability with state systems, and interoperability with surrounding counties <br /> and jurisdictions. <br /> Federal Engineering's Spectrum Center of Excellence has immediate access to FCC <br /> databases and is constantly apprised of all issues surrounding frequency acquisition and <br /> Copyright Protected Do Not Duplicate 29 �, <br />
