    The triangle of compromise

    Speed
    Bandwidth
    Range

    You cant have all 3. Just like manufacturing

      Speed and bandwidth are the same thing. Power is the other side of that triangle.

      But that ignores encoding, and other tricks like signal shaping, frequency multiplexing, and all kinds of fun stuff. Wireless data transmission is complicated. For example: en.wikipedia.org/…/Quadrature_amplitude_modulatio…

        Sorry ment power, bandwidth, range

      To be fair most wifi is used within homes or businesses these days so I would simply sacrifice range — as long as the minimum range is reasonable

        5G mm wave can be blocked by paper ffs, range doesnt matter if a leaf can block the line of sight. Idk why we can use the low bandwidth long range 900-1200mhz and just use an array of atenna send out multiple channels to increase bandwidth. I’d prefer range over bandwidth I wont utilize

    And what are we downloading? Is the cloud dead? Why do i need 15gbps on my phone? Is it made for consoles and their relentless 120gb patches?

      1.5gb/s is way more than enough for the average person. Hell, 200Mb/s is more than enough. That would only be 10 min.

      One example I’ve read, was to remotely drive autonomous vehicles, and feed back all data collected from cameras and sensors. I’m not a fan of it being used this way, but it would mostly serve that kind of purpose.

      In the US we’ll do anything but build fiber with the billions we tossed at the telecom industry.

        Putting fiber in the ground is expensive. I work for an ISP, and we estimate fiber overbuild costs at $15/ft. So a mile of underground fiber costs about $79,200.

      Everything, no, to move data quicker, no
