Interoperability Requirements

• Day-to-day
• Task force
• Mutual aid

6
Day-to-Day

• Commonly used in areas of concurrent jurisdiction
• Agencies need to monitor routine traffic
• Minimizes need for dispatcher-to-dispatcher
  interaction
• If agencies on different bands, may involve
  multiple radios
• Difficult for personnel using portable radios
• Infrastructure-based interoperability is not
  efficient due to continuous use of extra RF
  channel by each participant in each band or system

7
Task Force

• Usually involves several layers of government
  (local/state/federal)
• Opportunity for prior planning usually present
• Generally involves use of portable and/or covert
  equipment
• Often requires extensive close-range
  communications
• Nature of traffic is such that wide-area
  broadcast is usually undesirable
• May rove in and out of infrastructure coverage
  (metro-to-rural, in and out of buildings, etc)
• Often implemented today by exchanging equipment

8
Mutual Aid

• Can involve many agencies with little opportunity
  for prior detailed planning (e.g., earthquakes or
  wildland fires)
• Often requires assignment of several to many
  small groups, each on its own talkgroup or
  frequency (tactical comms)
• Once on-scene, generally involves use of portable
  radios
• Many incidents are in rural areas out of
  infrastructure range

9
Means of Technical Interoperability

• Shared radios
• Shared channels
• Interconnects
• Proprietary systems roaming
• Standards-based shared systems

Software Defined Radio Why Is Public Safety
Interested?

• Ultimate interoperability solution - single on
  the belt radio with todays characteristics,
  supporting
• Public safety and commercial bands (below 1-2
  GHz)
• Applicable commercial and public safety waveforms
• Permissible communications links as determined by
  the agency
• Graceful upgrade of products
• Graceful migration of technologies
• Clearly the wireless future and already here
  today
