Internet fiber optic cables transmit via E-M waves in the light domain, instead of the radio domain. The frequency of the light is typically around 1500 - 1600 nm. A single fiber can also carry multiple frequencies (wavelength multiplexing). These different wavelengths are about 0.8 nm apart. Although some radio waves might be used in your downloads ...

When you receive your radio-wave TV signal over the air using an antenna, the electro-magnetic wave is converted to electrical AC current that includes the same frequencies as the radio-wave. This antenna captures the radio (aka TV) electromagnetic wave via the Electric field strength part of the electromagnetic wave. The Antenna is connected to your TV ...

The waves that carry signals for the internet are the same kind of waves used for radio and TV. It is also the same kind of wave as for visible light, x-rays, and gamma rays. The difference between these waves is frequency and wavelength. Radio and TV use waves longer, lower frequency waves than you can see. X-rays and gamma rays are shorter and higher ...

Internet signals are mostly transported via cables. Some satellite links exist but they are less common. So we have cables and signals within them. Some cables are made of conducting metals others are glass fibers. The signals in the glass cables do not have the same properties as the ones in the metal wires, they are basically light that is sent through a ...

To answer such a question you need to set some parameters. The obvious thing to do is to ask whether, with our current technology, we could detect ourselves at the distances you suggest? The answer is no. You can find some more details in the related question Detectability of interstellar messages In summary, the most powerful radio signals we send into ...
