The picture you clicked on is a thumbnail of an 11x17 network pathway for Radio Interoperability for the entire State of Oklahoma. This is one of many Visio diagrams I produced for the State of Oklahoma which have included Network Diagrams for Layers 1, 2, and 3; Software Communication Schematics, System Schematics, and Electrical Schematics. I also can prepare business flows and Power Point training slides have done so for the State of Oklahoma and for the United States Army.
