    We now come to communication speed issues like high-definition video images (4K/8K) or in some cases multi hop technology is not enough to reach an isolated and distant PLC terminal. HD-PLC Quatro Core has been designed to solve these problems. This technology is an improvement on the conventional HD-PLC in both communication distance and speed.

    The photo also shows an unrelated distribution transformer, which reduces 4160 V to 240/120 V. Closeup of overhead powerline sensor hanging from one phase of a 4160 volt powerline. In the photos on the right, an antenna on the sensor transmits data to a communication device attached to a nearby utility pole.

    en.wikipedia.org/wiki/Broadband_over_power_lines

    IEEE P1901-2020 "IEEE Standard for Broadband over Power Line Networks: Medium Access Control and Physical Layer Specifications" is a working group for delivering broadband over power lines. The aim is to define medium access control and physical layer specifications for all classes of BPL devices - from long distance connections to those within ...

    Hungary: The first powerline service in Hungary was realized in September, 2003, in the Riverside apartment house in Budapest by 23Vnet Ltd. The PLC equipment was supplied by ASCOM Powerline. After four months the service was counting 100 users from 450 apartment owners. The bandwidth is 4.5 Mbit/s. [7] Asia, Pacific, and Oceania: Indonesia:

    The IEEE 1901 Standard was a significant step in the development of powerline communication (PLC) technologies. PLC allows for data communication over existing power lines, which can be particularly useful in environments where it's difficult to lay new wiring or where wireless communication might be problematic.

    UHV transmission and a number of UHVAC circuits have already been constructed in different parts of the world. For example, 2,362 km of 1,150 kV circuits were built in the former USSR, and 427 km of 1,000 kV AC circuits have been developed in Japan (Kita-Iwaki powerline). Experimental lines of various scales are also found in many countries. [7]
