5、le, flexible. The earth-wire-bus communication line neither be dynamited nor be break off , it is the most reliable communication line in the world. Supply the gap between wire and wireless is call E-Wire Bus technology (Earth-wire-Bus).,One distinctive feature is the possibility of using only one e

This earth wire is the steel rail, steel pipe, steel truss, drill pipe and so on, a iron communication.,Iron communication network,Once central switch be burned the star network will breaks down. Earth-wire-bus system use a steel pipe, rail, cables as a Token Ring
