The curious thing about wireless backhaul is the fact that a wire brings electricity to all these towers, fixtures, antennas and assorted equipment. "For example, while cell phones communicating with a single cell tower, powered by a connection to the electrical grid, constitute a local subnetwork, the connection between the cell tower and the rest of the world begins with a backhaul link to the core of the telephone company's network." Just how many venues actually require wireless in order to connect with the network system when an electrical cable is obviously already in place to provide power, ie the wire providing electrical service got there somehow. LMDS equipment, which has such rain fade problems that the distance between towers is short, would still require electricity. How is providing and maintaining all those extra remote electrical connections economically feasible?
