Data System Design Issues

• Current desire for data services
• Rapid evolution of data technology
• Montana State standard DataTAC system
• State-of-the-art dedicated data system
• Shared P-25 data/voice operation
• High cost of ubiquities data system coverage

18
VHF P25 Data System Design

• Provides 9600 BPS data transfer
• Relatively low capacity data
• Shared channels with voice communications
• Overlay design requires no additional sites or
  transmitters
• Low cost implementation
• Rapid deployment for data evaluation

UHF Dedicated Data System

• RD-LAP (DataTAC) Data System
• Expansion of current DataTAC systems implemented
  elsewhere in the State
• Compatibility with existing system and terminals
• Not fully IP compliant
• Becoming an obsolete technology
• Leverages existing investment
• Dedicated High Speed Data System
• State-of-the-art replacement for current DataTAC
  systems
• Fully IP compliant
• Not compatible with existing system and terminals
• Leverages new technology

21

22
Data Communications System Design

• P25 Wide Area Data where appropriate
• Evaluate DataTAC vs. new technology data
• Expansion of dedicated data system
• Standardized IP network architecture

23
Interconnection System Design

• Digital Microwave Backbone
• Use of Public Utility Digital Connections
• Where high reliability can be assured
• Fiber Connections
• Where microwave paths may not be cost effective
• Long Backhaul Spurs
• Common T-Carrier Standards
• Consistent Network Interface

Next Steps

• Cost estimate development
• Estimated schedule development
• Prioritized implementation plan
• Match implementation to funding
• Refinement of design
• RFP development

26
Project 25 Standards

• It is the only viable standard for Public Safety
  Mobile Radio communications
• Promotes vendor independence
• It provides a broad range of system
  implementation options
• From simple conventional to complex trunking
  systems
• Supports simplex, repeater, trunking, simulcast,
  etc
• P25 has been developed and endorsed by the Public
  Safety community including
• APCO (Association of Public Safety Communications
  Officials)
• NASTD (The Association for Telecommunications
  Technology Professionals Serving State
  Government)
• P25 complies with FCC narrowbanding requirements
• It provides both digital and legacy analog
  operation
• Does not obsolete existing equipment
• Will not be obsolete in the near future
• Allows for operation on analog mutual aid channels

27
Project 25 Standards

• It complies with DHS/SAFECOM recommendations
• P25 has been strongly recommended or required in
  many Federal grant programs
• P25 is the Interoperability standard for Federal
  systems
• It is the only multi-vendor standard for features
  above basic PTT (push to talk)
• Emergency call, encryption, trunking, etc
• It provides easy migration to higher feature
  systems without coverage or feature loss, while
  maintaining vendor independence
• Market prices are being driven down and product
  selection is expanding as additional vendors
  start manufacturing P25 compliant equipment
• Additional vendors have indicated they will be
  releasing P25 products in the near-term further
  lowering prices

28
State Wide P25
Recognizing the benefits, many states have
either selected or mandated P25 as their Public
Safety mobile radio standard including

• Alabama
• Alaska
• Colorado
• Georgia
• Kentucky
• Michigan
• Minnesota

• Montana
• New Hampshire
• North Dakota
• South Dakota
• Virginia
• Wyoming

Other states are seriously considering, or are in
the process of moving to P25 as their standard.
