Increased number of collectors may increase throughput and reduce latency. RF – Mesh AMI 8 © The National Rural Telecommunications Cooperative

9 Corporate Network AMI Server MDM Server Other Servers Wide Area Network Or Direct Backhaul WAN communications from office to substations via radio, fiber, or satellite LAN communications from towers to meters use custom designed techniques which allow meters to communicate to more than one tower using longer range licensed wireless (Tens of miles). Same network can support Distribution Automation and other applications. Towers may be added for improved coverage. RF – Tower AMI 9 © The National Rural Telecommunications Cooperative

16 MDM is….. The evolution of Load Research Systems created in the 1970’s to serve commercial and industrial customers, wholesale interchange metering, and PURPA. A platform that enables fundamental changes in how utilities operate using vast amounts of measured data and information A centralized data management and data storage platform for existing data and future data collected from AMI systems and new Smart Grid technologies A centralized integration point for integrating utility applications utilizing web-services, Multi-Speak, ODBC, XML, etc. Centralized data analysis and reporting of all operational data A provider of Interval Data Validation, Editing and Estimation (VEE), Meter Read Profiling, Load Research, Energy Settlement, Energy Data Presentation, and Line Loss Analysis A foundation for launching future customer programs including new customer-premise devices (e.g., HAN, Smart Thermostats) 16 © The National Rural Telecommunications Cooperative
