AMR: The Next Generation Reliable Communication at Lower Cost AMR Is the Future Utilities around the world are moving to Automatic Meter Reading (AMR) metering infrastructure. However, high capital investment cost and data communication problems have presented significant challenges to many companies. In fact, initial expense and ongoing reliability issues may offset the potential benefits of reduced meter reading costs and improved supply management. That is, until Nanjing Sanneng introduced their solution to AMR: the Net-Bridge AMR meter. The Sanneng Net-Bridge multi-modal mesh AMR system overcomes many of the problems inherent in earlier AMR equipment. The result: greater flexibility, high reliability, and lower cost. The Evolution of AMR First generation RF based mobile AMR systems had significant limitations, e.g., unreliable, one-way data transmission, the need for relay/repeater stations in high rise applications, and advanced scheduling of collector routing. Power Line Communication (PLC) based AMR systems operating over considerable distances often have high error rates due to spikes and background noise. Cellular (GSM/CDMA) based AMR systems offer two way communications, but cost more to purchase and to operate. AMR: The Next Generation Sanneng's Net-Bridge system features the low cost of PLC systems and the reliability of the most expensive cellular based systems. The multi-modal mesh system is both intelligent and flexible. Sanneng's sophisticated AMR meter determines the most cost-effective, reliable way to transmit data, automatically switching between PLC, infra red and RS485, if available. Two-way communication allows reprogramming of meter reading function as well as the interval between readings. All meters within a distribution transformer act as a local area network. By acting as a relay and concentrator, Sanneng's advanced AMR meter allows a handheld infrared device to read each of the networked meters from any one meter within the network. Nanjing Sanneng AMR -- Fail-Safe, Reliable, Affordable Sanneng's multi-modal mesh system is truly an endless, fail-safe, self-healing network. Net-Bridge equipment delivers unprecedented reliability at the lowest possible cost. The Net-
