Orange County Emergency Management, North Carolina <br />Final VIPER Anal sis Re ort Au ust 20, 2004 <br />VIPER sites outside of the county providing coverage support in Orange County <br />are shown in the maps as follows: <br />• D-Cane Mtn. (Cane Mountain) in Alamance County <br />• C-Durham City (Durham) in Durham County <br />• C-Butner (Butner) in Durham County <br />• C-RTP ETV (Research Triangle Park) in Durham County <br />NC-SHP has stated the following sites shown on the coverage maps will not be <br />constructed. <br />• D-Burlington in Alamance County <br />• C-NC-55 in Wake County <br />• C-Durham/MI in Durham County <br />Users in Orange County operating portable radios should experience good on-the- <br />street coverage throughout the county, except in the West Central, and <br />Northeastern portions of the county depicted in blue and red on FIGURE 4-1. <br />FIGURE 4-2 with 0 dB gain provides an indication of coverage expected in light <br />buildings up to 6 dB loss when compared to FIGURE 4-1. Users operating in the <br />close proximity to the VIPER sites (yellow high signal areas) should have <br />sufficient RF signal margin to communicate in medium density buildings having <br />higher loss than light buildings. This is based on the assumption all planned <br />VIPER sites are operational and constructed using the same parameters as used in <br />the coverage map predictions. <br />4.2 Traffic Loading <br />In observing the usage of trunked radio systems installed by each of the major <br />vendors, we have found that communications systems serving public safety <br />operations have predictable use patterns and loading requirements. <br />The remainder of this section discusses traffic loading as it relates to public safety <br />support functions. <br />"``°_ Section 4 -VIPER Coverage and Capacity <br />Page 13 of 43 <br />
