IJ <br />5.4 Recommendations ' <br />Table 9 lists the recommendations for the City's traffic communications network based on the ' <br />advantages and disadvantages described in the previous subsections and input from City staff. <br />These recommendations are also depicted in Figure 12. Key advantages that played a role in <br />the selection of a fiber optic trunk line include the capacity for future system expansion and ' <br />sharing opportunities for a network that supports both Public Works and ISD infrastructure. <br />Leased services were not considered a viable option due to the difficulty of obtaining annual <br />funding for leasing fees. The lower cost wireless alternative is recommended for unserved areas ' <br />where bandwidth and clear sight lines permit while either fiber optic cable or twisted pair copper <br />cable is recommended based on system requirements when wireless is not feasible. <br />Table <br />' <br />9. Communications Deployment Recommendations <br />• Move Pearl St hub to RIS. <br />• Locate all new future traffic servers at RIS. This includes installing a new <br />' <br />video server at RIS during the first project that includes communications to <br />existing or new CCTV cameras. <br />• Maintain Roosevelt Blvd hub. <br />' <br />• Install fiber optic cable and Gigabit Ethernet switches along major arterial <br />roadways for communications to field devices. <br />• Share fiber infrastructure with ISD or ODOT when mutually beneficial. <br />, <br />• Install Ethernet over copper to low bandwidth devices where copper is <br />currently used on laterals to trunk lines. <br />• • Install wireless to unserved infrastructure with low bandwidth requirements <br />' <br />and clear sight lines. <br />• Install fiber optic cable and Gigabit Ethernet switches to unserved areas <br />where there are high bandwidth requirements or a communications <br />, <br />connection can be made to a City facility. <br />• Where wireless is not feasible, install either fiber optic cable or Ethernet <br />over copper depending on the medium used where the unserved area is <br />, <br />connected to the communications network. <br />1 <br />1 <br />1 <br />u <br />uno Hssuc /tires tugene Master Traffic Communications Plan March 2008 , <br />Page 31 <br />
