FE will develop the following four radio coverage <br /> prediction maps comparing existing and expanded VHF High Band LMR and paging/alerting <br /> coverage: <br /> • Existing VHF High Band on-street and in-building LMR coverage <br /> • Expanded VHF High Band on-street and in-building LMR coverage from an expanded <br /> VIPER system using additional sites <br /> • Existing two-site analog VHF High Band on-street and in-building paging/alerting radio <br /> coverage <br /> • Expanded VHF High Band on-street and in-building paging/alerting radio coverage from <br /> an expanded VIPER system using additional sites <br /> 2.2.3 Task 2.3— VIPER Expansion Capacity Analysis <br /> FE will perform VIPER expansion capacity analysis to estimate the number of radio frequency <br /> channels needed to provide public safety grade of service using both P25 Phases 1 and 2 <br /> formats, given that VIPER operates using P25 Phase 1. <br /> 2.2.4 Task 2.4— VIPER Expansion System Features Analysis <br /> FE will research the ability of the VIPER system to provide system features including encryption, <br /> over-the-air-rekeying (OTAR), over-the-air-programming (OTAP), and location services. <br /> Inclusive of FEs research, we will evaluate the degree to which the County is able to locally <br /> manage VIPER system features and channels/talkgroups. FE will also determine whether the <br /> County's existing Motorola Solutions MCC7500 IP Dispatch Consoles will support VIPER <br /> feature enhancements. <br /> 2.2.5 Task 2.5— VIPER Expansion Backhaul Analysis <br /> FE will review the County's options to provide backhaul connectivity for an expanded VIPER <br /> system, including the use of microwave radio and leveraging the existing Microelectronic Center <br /> of North Carolina's (MCNC) North Carolina Research and Education Network (NCREN). FEs <br /> research will identify where NCREN has optical fiber points-of-presence (POPs) geographically <br /> located that may potentially be leveraged to expand the VIPER system for the County's day-to- <br /> day use. <br /> Page 3 of 7 <br />
