    Julian Dominguez 3 недели назад It's still stupid. In my free time, I've drawn dozens of models of how phones communicate. This is nowhere near what I expected. After all of this research in technology, this is what they come up with? I hope that one day I would make this better...

    Ammar Siddiqui 2 месяца назад @auras ian like finding a needle in a haystack. You can't just look up and see satellites. You could see the ISS with a telescope though.
  • auras ian
    auras ian 2 месяца назад @Ammar Siddiqui why satellites is not use for mobile telephony?
  • Ammar Siddiqui
    Ammar Siddiqui 2 месяца назад @auras ian There are satellite phones out there, you can buy some from Amazon. Satellites are used mainly to transmit long range data across the planet (which is a sphere). If it wasn't for satellites, the flat-brainers wouldn't be able to communicate on their Facebook groups.

  • Anthony Robertson
    Anthony Robertson 3 недели назад (изменено) auras ian Because satellites are expensive to put up and not easily repaired. It's easier and cheaper to maintain and use cables on the ocean floor and across land. Satellite phones are pretty expensive to use, and signals are much easier to recieve from just a mile or two away. Satelites are several miles in the sky. Satellites are mostly used for cable tv, not the internet, though you can get small dishes for satellite internet if you are not in a DSL area, my dad had to for a few years, but it's more expensive and data use is limited. It's extremely unlikely that your internet/cellphone use ever goes over satellite transmissions.
