Why do TV remote manufacturers employ infrared signaling instead of radio wave signaling?

And what are the benefits of employing EMR signals of different wavelengths? I would think some are much more penetrating than others. Any other significant differences?

    I have often wondered the same thing. I suspect it is because IR’s all there on the same wavelength through it a great chance of interference with RF remote controls werden.Es would much easier to use if even if they do not have sight of the line-of-and you want you can use your DVD, etc in a cupboard.

    Because infrared work, at small distance, thats why it is used and 2 what radio wave works by great distance, that could cause side effects

    IR is cheaper. If you make millions of devices, a few dollars cheaper, makes a big difference. Lower performance than RF is acceptable to customers, so OK.
