| 1. A method of transmitting at least one digital code over a network carrying AC current comprising:
transmitting a signal corresponding to the code over the AC current network using the AC current for determining timing of
transmission,
wherein, for each code, the signal is a sum of sine waves of several frequencies with phases selected between 0 and 2π for
each frequency,
wherein the same frequencies are used for all codes, and
wherein the set of phases is unique for each code.
