FAQ

Those who are looking for an answer to the question «Why not frequency modulation over cable for internet?» often ask the following questions:

💻 What frequency is cable internet?

What frequency does cable Internet use? Some of the modern cable operates above 550 MHz, often to 750 MHz which is used as downstream data. The upstream channels are introduced in the 5-42 MHz band and frequencies at the high end for downstream. Click to see full answer.

💻 What frequency does cable internet use?

A common frequency range for downstream channels (or your download speed) is between 54 MHz to as high as 1000 MHz. For upstream channels (or your upload speeds) the range is 5 MHz to 42 MHz.

Because of this configuration, cable TV networks do not offer problems with the quality of the cable, the length of the cable, or electromagnetic interferences (EMI) that plague typical DSL ...

With a tone-modulated FM wave, if the modulation frequency is held constant and the modulation index is increased, the (non-negligible) bandwidth of the FM signal increases but the spacing between spectra remains the same; some spectral components decrease in strength as others increase.

Frequency Modulation. Frequency modulation (FM) is that form of angle modulation in which the instantaneous frequency fi(t) is varied linearly with the baseband signal m(t), as shown by(10)fi(t)=12πdi(t)dt=fc+kfm(t) From: Encyclopedia of Physical Science and Technology (Third Edition), 2003 Related terms:

The bandwidth of an FM signal has a more complicated dependency than in the AM case (recall, the bandwidth of AM signals depend only on the maximum modulation frequency). In FM, both the modulation index and the modulating frequency affect the bandwidth. As the information is made stronger, the bandwidth also grows. Efficiency

The TV channels and Internet channels are frequency multiplexed and modulated on to the main fiber-optic cable for transport out to distribution hubs that rejuvenate the signals over longer cable ...

Amplitude Modulation is not only the approach of modulating the signal, but there also exist many other kinds of modulation techniques. Frequency Modulation is one of the types of modulation. In the earlier days of communications, the necessary bandwidth for transmission of signals was not wide and even they do not hold the ability to reduce the interference signals.

At this time, 10 MHz over UTP (100Base-T)had been around for a couple of years, and the standard established 3 categories of cable for signal/data use. Category 1 - voice/analog only, up to 1 MHz. Although it was not specified for data, it was often used at low data rates. Category 2 - Data to 4 MHz. Category 3 - 10BaseT, data rates of 10 Mbit/sec.

One of the most common causes of upstream power problems is splitters. If possible, your cable modem for your internet should be on the first splitter attached to the line that comes in from your house. Further splitters will degrade the signal quality — TVs can handle it, but you will see more noticeable problems with the internet.

If you’re using a Powerline adapter and you have a radio amateur living two or three doors away, you may be broadcasting noise on a frequency he’s using for his hobby. The interference can radiate out around 100 metres. There’s also evidence that Powerline adapters can cause interference to FM and DAB radio reception.
