Abstract
Improvement in the construction of intercom devices characterized by the fact of creating a carrier band of 144 kzh. Modulated in amplitude in the device that at that moment acts as an emitter and through the electrical distribution network, it is captured by the device that then acts as a receiver and that is plugged into the power network that has the same phase as the one in which the transmitter and the receiver are plugged in, by means of the general electrical installation of the building, with no need for installation between both intercoms.
