Abstract
A method for concurrently communicating over each phase of an electrical power distribution network (N). A first outbound signal (SO1) is transmitted over one phase (AN-A) of a bus (S) by an outbound modulation unit. The unit is released as soon as the first outbound signal (SO1) is transmitted so the unit can transmit a second outbound signal (SO2) over a second phase (BN-B or CN-C) of the bus. The second outbound signal is transmitted concurrently with an inbound signal (IB1) sent in response to the first outbound signal (SO1). The unit is again released, as soon as the second outbound signal (SO2) is transmitted, so the unit can transmit a third outbound signal (SO3) over the third phase (BN-B or CN-C) of the bus. This third outbound signal is transmitted concurrently with a second inbound signal (IB2) sent in response to the second outbound signal (SO2). The method allows concurrent communications over all three phases of the network (N).
