3m92, PAuF .115. <br />A�� 2� 1�9� <br />There are over thirty (30) known radio licenses with 124 channels <br />or frequencies associated with public safety in Indian River <br />County. There is no way the various agencies and systems can be <br />tied together to achieve interoperability and effective use of the <br />communications should a disaster occur, or just on a day to day <br />basis when agencies -need to talk to more than one entity. <br />Like many counties across the country, tight budgets and parochial <br />thinking among agencies have spawned dozens 'of separate <br />communications systems acquired over the years. Each agency has <br />its own frequencies and purchased various types of equipment when <br />they needed it without much thought to interoperability issues. At <br />some emergency scenes now, it is easier to yell at. personnel to <br />exchange information than to use the radios because of the <br />inability to talk to one another without going through dispatchers. <br />Today, there is more interest being shown than ever by local and <br />state governments and federal agencies in the need for radio <br />interoperability between agencies. It has become a critical issue <br />for everyday operations, including ongoing federal, state and local <br />efforts, involving major criminal investigations and drug task <br />force operations, as well as in major disasters and public events. <br />Interoperability would allow state police to talk to drug <br />enforcement agencies, local law enforcement departments, even fire, <br />emergency management and emergency medical services, all operating <br />at the same emergency incident. <br />It is- clear the country is moving from analog signals for <br />transmission of voice messages to -a combination of digital voice <br />and data transmission technology. Analog signals are electrical <br />energy in a communications system which varies continuously in <br />amount and/or frequency in accordance with the characteristics of <br />a signal, such as voice into a microphone, put into -the system. <br />Digital means signals which take voice or computer data and convert <br />them into bursts of radio energy representing ones and zeros. (or <br />ons and offs). These burst of energy are then converted back into <br />their original form at the receiving end in order to be heard or <br />read. <br />An example of digital/data transmission (without a voice) is when <br />one pushes a button on a radio to let the receiving station know <br />the sender is in or out of service, to request an ambulance, fire <br />equipment, law enforcement assistance, check for outstanding <br />warrants on an individual, obtain vehicle registrations, access <br />FCIC, NCIC,-change traffic signals at intersections, obtain meter <br />readings,. all possible from a vehicle without using voice <br />capabilities. <br />Digital voice radio also improves radio spectrum efficiency by <br />dividing a radio channel into two or more individual channels and <br />integrating voice and data transmissions in the same channel's <br />signal instead of having to use two separate radio channels. <br />Digital technology is.here now and will be much more prominent in <br />the future. <br />Given the information provided above, there are various <br />alternatives for the Board to consider regarding current and future <br />communications systems. <br />10 <br />
