How can Internet data be transfered through the electrical wiring of a house without degrading or interference if power cables cause interference to data cables

Question

I’m not sure if I am explaing this right or how it works and I haven’t been able to stop thinking about it for weeks.

So if a power cable emits a magnetic field which can interfere with data transmission through data cables, then how can a tp link, for example, use the mains or cabling of power currents to transfer Internet through a house without being degraded beyond use

Answer 1

Internet is not transferred along power lines. A tp link is a wifi extender. It picks up the wifi signal, amplifies it, and sends it back out. To emphasize this point, no data is ever ever transferred along electric lines. It does not work that way. Electric lines do put off an electromagnetic field, but one wire is not enough to interfere with anything, it would take a coil of wire to produce enough.
