What technology enables networking over electrical wiring?

Powerline Networking is the technology that allows networking over existing electrical wiring. It utilizes the electrical infrastructure already present in homes and buildings to facilitate data transmission. By using the power lines to carry data along with electrical current, devices can communicate with each other without the need for additional networking cables or wireless solutions.

This technology converts data into signals that can coexist with the electrical current, making it possible to connect devices in locations that might be difficult to reach with traditional networking methods. As a result, users can take advantage of high-speed internet access or network connectivity in parts of the building where it might not be practical to run new cables.

The other options refer to different technologies that do not utilize electrical wiring for networking. Radio Frequency pertains to wireless communications rather than wired connections. Ethernet Switching is a method used for managing network traffic over wired connections but does not specifically use electrical wiring itself for data transfer. Telecommunication encompasses a wide range of communication technologies but is not exclusive to networking over electrical wiring.
