Currently the City of Eugene Public Works department has <br /> approximately 153 pieces of equipment falling into this category that need to be updated. In <br /> addition the FCC plan calls for all VHF and UHF radio systems to be capable of operating at 6.25 <br /> kHz after 2018. The 2018 change to digital would require the change of 298 pieces of equipment. <br /> At the 2018 channel spacing, analog radios will not function effectively and can only be <br /> performed using digital radios. <br /> Decision points <br /> There are three options that the department will need to consider: <br /> 1) Upgrade our existing 153 pieces of Public Works equipment to meet the 2013 narrow <br /> banding regulation. <br /> 2) Upgrade the existing 298 pieces of equipment so that it will not only meet the 2013 <br /> requirement but also the upcoming 2018 changes. In order to meet the 2018 requirement we <br /> will need to go digital. <br /> ➢ By 2013 all frequencies below 512 MHZ will need to be at 12.5 KHZ Deviation <br /> ➢ By 2018 all frequencies below 512 MHZ will need to be at 6.25 KHZ Deviation <br /> 3) Upgrade all of our 298 pieces of equipment so that we not only meet all of the upcoming <br /> changes through 2018 but also become trunking capable. This will enable us to be fully <br /> interoperable with public safety agencies in Lane County that are currently on the trunking <br /> system. <br /> Page 1 of 3 <br />
