9. Rural Electrical Cooperatives What is a rural electrical cooperative anyway? What is a rural electrical cooperative anyway? –Local power companies who provide service in rural areas, that are owned by its customers. –Service areas often include vast amounts of sparsely populated farm land. A “small” coop can service 900 square miles. –High load farm equipment, such as corn dryers and irrigation pumps.

10. Why do rural areas benefit from AMR? Customers are few and far between. Customers are few and far between. Readings can be difficult to obtain. A meter could be in the middle of a corn field. Readings can be difficult to obtain. A meter could be in the middle of a corn field. Customers benefit more, due to their high electrical usage.

15. The Solution: Mesh Networking

16. Mesh Networking Mesh networking enables small individual nodes to talk any other node in a system. Mesh networking enables small individual nodes to talk any other node in a system. If there is a problem with a particular node, other nodes can “hop” around that node to get to their destination. If there is a problem with a particular node, other nodes can “hop” around that node to get to their destination. No “infrastructure” needed. Just add nodes as you need them.

18. How it works An “8841” is installed on the meter. An “8841” is installed on the meter. –An 8841 as an embedded computer that can talk with the microchip embedded in the electrical meter. –An 8841 also has a long range radio attached to it. –8841’s can talk to each other via the radio.

23. Mesh Implementation All 8841’s try to send data to an 8856, based upon a “link layer” All 8841’s try to send data to an 8856, based upon a “link layer” If an 8841 cannot hear an 8856, it looks for another 8841 who can. If an 8841 cannot hear an 8856, it looks for another 8841 who can. An 8841 will store several units in a routing table, and choose the best path to reach an 8856.
