LAN over power supply network
Everyone is faced at least once with the problem to provide computer access point to a place that is physically inaccessible due to structural obstacles or due to unable to lay the new route (it would be broken esthetic appearance of the room). For example, you have changed your old TV with new one that has a LAN port, but when the wiring was done it is provided only electrical outlet. Another example is the situation when the cable trace that you need to build will go through someone else’s property. Possible solution furthermore to use WiFi Access Point, is to use existing electrical wiring in the home (dotted line in the picture below)
Disadvantages of WiFi is that it can not be used in places where there is strong attenuation of radio waves (2,5 GHz or 5 GHz) and require several devices to achieve good speed and strench of the signal, which is the least uneconomical.You come to the aid devices that use a transmission medium already established – the power supply grid in the home.
