How would anyone know that there's a problem? No more analog television, and the only AM radio I have is in the car. What would Ethernet power-line interference look like?
On FM, the signal would just disappear into the noise and the interference wouldn't be noticeable until just before that happened. Same with digital TV. Also, there are a lot of other radio services that use the various parts of the spectrum. We'll soon be getting cell phones on 600 MHz, which used to be allocated to TV. Some of those radio users include emergency services, aircraft, amateur radio and more. So, just because you don't hear interference on your radio, you can't assume you're not interfering with something else. There are the ISM bands where devices are allowed to generate noise, including the bands used for WiFi and others. Even there, there are limits. Here is a chart of the various radio spectrum assignments in Canada. The situation would be similar elsewhere. There's not much where there isn't some service using the spectrum. https://www.ic.gc.ca/eic/site/smt-gst.nsf/vwapj/spectallocation-08.pdf/$FILE... -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
