    • Solution Options To achieve interoperability, you can: Adopt Radio Standard Adopt Network Standard Everyone Uses same radio and system IP Network supports all existing radios and systems or
    • Interoperability Through the Customer’s Eyes
      • What it means
        • The ability to communicate between mobile and fixed personnel participating in group -based, coordinated , operations
      • What is necessary
        • A vision and an operational plan
        • Cooperation between participating agencies
        • Products and technology
      • What it needs to accomplish
        • Remain non-intrusive for normal day-to-day operations
        • Support pre-planned and unplanned scenarios
      • Perspectives of different types of buyers
        • Economic: How do I maximize return on current investment and what do I get for my incremental investment?
        • Technical: What service do my users really need?
        • Political: What have I contributed to the security of my constituency?
    • The Present State of Public Safety Communications
      • Federal
        • Utilize federal NTIA regulated bands
        • Most agencies use analog non-trunked, some analog trunked use
        • Beginning deployment of P25 conventional, increased interest in P25 trunking
      • State
        • Most state-wide networks are Low band & VHF conventional analog
        • State Patrol and DOT’s tend to drive statewide use
        • Regional use of VHF and UHF bands
        • Very limited deployment of statewide trunking
        • Some early migration to 800 MHz digital trunked
      • Local Tier 1 County and Municipal
        • Analog trunked radio with migration to digital trunked radio
      • Local Tier 2 County and Municipal
        • Conventional analog with some early migration to conventional digital P25
    • The Interoperability Problem
      • Multiple Agencies:
        • Federal, State, County and Local
      • Multiple Frequency Bands
        • VHF-low, VHF-high, UHF (low, T-band), 800, NPSPAC, 700 (proposed)
      • Multiple Vendors - Proprietary Protocols
      • Other Variables:
        • Multiple SW revisions, control channel rates, etc.
        • Narrowband & Wideband
    • The “Ideal” State
      • An ubiquitous network with:
        • Coverage everywhere
          • A user can use his/her radio wherever they are asked to go
        • Full connectivity
          • A user can communicate with whomever he/she needs to
      • Barriers to achieving the Ideal State
        • No unified frequency plan
          • Every band exists everywhere … but
          • Band use is licensed for individual use – no clear concept of resource sharing
          • This is not a technical issue it is a regulatory issue
        • Today’s radios do not implement effective mobility management
          • Requires user to remain cognizant of coverage (channel)
          • Trunked systems address part of this concern
        • The radio channels that are in use are not part of a comprehensive switched network
    • State-of-the-Art for Interoperability
      • Simulcast Trunked Radio Systems
        • Separated the channel from the group
        • Full interoperability for all participating agencies
        • Allow roaming within the coverage area
        • Users select whom they talk to
        • Dispatchers can patch groups together for increased interoperability
        • Interfaces to conventional radio systems
      • Wide Area Multisite Trunked Systems
        • All the features of Simulcast Trunked Radio Systems
        • With increased coverage area
        • Conventional overlay for legacy radios and interoperability with local governments
        • Network interfaces to existing trunked systems
    • A Long-Term View of Interoperability
      • Probably the best long-term interoperability solution is:
        • Statewide Digital Trunked Systems with:
          • Conventional Overlay to analog systems within the state
            • Federal, state and local level
          • Networked Trunked interfaces to existing trunked systems within the state
      • Why states:
        • Significant geographic coverage
        • States can bridge the gap between Federal and Local governments
        • States have the right economies of scale
        • Statewide systems are becoming practical to implement
      Homeland Security money will be funneled through the states
    • Short Term View of Interoperability
      • What drives the short-term view?
        • Minimal cost – maximize leverage of customer’s existing equipment
        • Fast to deploy – Must be capable of being deployed across a state in less than 3 years
        • Provides a technology step towards the long term solution
      • The answer is NetworkFirst!
        • Start with a modern network backbone
          • IP packet switched
        • Interconnect existing conventional and trunked systems
        • Enable incremental investment to achieve the long-term objective

      Strategy
      • Not scalable
      • Not selective between talkgroups (patch vs switch)
      • Not a wide-area solution
      • Not user driven – user doesn’t decide who he/she talks to
      • Does not address operation in different frequency bands
      • Does not address interoperability with non-P25 systems
      • Does not increase system capacity
      • Increases service area not coverage
      • Requires an IP wide area network
      Issues
      • Add-on to existing systems
      • Highly economical
      • Migrate from analog to digital
      • Replace existing system
      • Replace terminals
      • Very expensive
      • Add-on to existing systems
      • No new terminals
      • Highly economical
      Economics
      • Console Patch
      • Cross band Radio Patch (ACU 1000)
      • Standardize on a digital air interface
      • Interoperability within the same band on the same channels
      • Interconnect existing analog and digital systems
      • Implement trunk-like features

    • The IP Backbone
      • IP Networks are comprised of a mesh of routers
      • Routers are connected by links such as point-to-point microwave
      • Routers use IP addresses to route packets from one link to another
      • Routers use routing tables to perform this routing function

    • Talkgroups
      • Talkgroups are the fundamental entities for facilitating interoperability
      • NetworkFirst Talkgroups have many of the same characteristics as in a trunked radio system
      • Most NetworkFirst functions are tied to the talkgroup
        • Inter and Intra-regional calls
        • Priority & preemption
        • Call control timers
        • Blocking and Non-blocking behaviors
    • NetworkFirst Security
      • Some observations about security
        • A system is only as secure as its weakest link
          • When dealing with conventional radio, the analog radio transmission is the weakest link
          • Easy to detect, easy to eavesdrop
        • To some degree security and interoperability impose conflicting requirements
          • Security limits access
          • Interoperability expands access
      • Within its boundaries, NetworkFirst provides security through encryption
        • Encryption is end-to-end: from DVU to DVU
        • Encryption utilizes the Advanced Encryption Standard (AES, FIPS-PUB-197 with 128 bit keys)
    • Configuring & Managing NetworkFirst Network Administration System Network Management System
    • Network Administration System Overview
      • Every NetworkFirst system includes a Network Administration System
        • This includes both single ROC systems as well as multi-ROC systems
      • A single NAS can configure a network of ROCs
      • The NAS is implemented in a multi-user, Client-Server, WEB-based architecture
      • Network Administration Server
        • JAVA WEB Front End – Implements the user interface

      • When you want interoperability on demand
      • When you want users to determine who they talk to
      • When you want a scalable solution
      • When you want a migration path
      • When you don’t have enough money to replace all your radios
      • When you don’t have 5 years to create a solution
