First Claim
1. A system for receiving and processing signals received from a plurality of endpoints, each endpoint including an endpoint transmitter in electrical communication with a power distribution line within a power distribution system, the system comprising:
- a power line coupler;
a substation transceiver in electrical communication with the power line coupler; and
a substation circuit in electrical communication with the substation transceiver, the substation circuit configured to simultaneously demodulate signals received from the plurality of different endpoints wherein the substation circuit being configured to simultaneously demodulate the signals comprises the substation circuit being configured to;
separate a channel on the power distribution line carrying the plurality of signals into sub-channels, andseparate each of the sub-channels into sub-sub-channels, each of the sub-sub-channels being respectively assigned to different ones of the endpoints, each of the sub-sub-channels having a predetermined bandwidth.
