15 Key Infrastructure Requirements: Operational Rules by Application Deployment Timeline by Application Data throughput and latency Frequency Of Data Transfers Interface Serial or Ethernet Reliability or Availability 99.9%, 99.99%, or % Battery and/or Generator backup Licensed vs. Unlicensed for wireless communications Ring Topology Versus Network Diversity or Secondary Link Coverage Requirements Monitoring or Control Applications Who (or What) is Waiting for the Data Direction one-way, two-way, peer-to-peer Circuit-switched packet-switched TDM Jitter (undesired timing fluctuations in a transmitted signal) 15

16 Recommendations from SGDP Create an application-level roadmap Define the actual requirements for each application Create a communications architecture plan Create a communications deployment build-out schedule Develop a plan for staffing and support during and after deployment Seek funding approvals from management team, board and other funding sources Begin detailed design tasks and procurement 16
