The concept of transmitting data over existing power cables has been around since the 1950s. Early research looked at using power lines for applications like closed circuit television in industrial facilities or telephone communications for rural areas that lacked traditional networking infrastructure. However, the technology really began to take off in the 1990s as digital communications increased and broadband internet became more prevalent. This opened the doors for high-speed power line communication (PLC) that could deliver data, video, and voice services over existing electrical wiring.
