Comment on SpaceX says states should dump fiber plans, give all grant money to Starlink

  Ever try a voice call with 30ms of latency?

  Lol what? You’re not gonna notice a 30ms delay in a voice call…

    Yeh, 30ms is still inside the haas delay.
    If you are a professional listener (sound engineer, musician, dancer) then you can probably perceive it (in a similar way that eyes theoretically only need 25fps, but 60/120/144 is noticeably better).

    In 30ms, sound can travel 10 meters.
    So, if you’ve ever had a conversation with someone across a classroom, you’ve had a conversation with 30ms latency.

    For data, 30ms is 8100 km for electricity over copper, or 6000km for light over fibre.

    Meaning 30ms over fibre (considering no transmission delays) would be roughly the direct distance between US and UK.

    So yeh, 30ms is nothing

    And I’ll downvote ya again, if I could :)

    FWIW, I don’t owe you a reply :)

      Of course you don’t, just pointing out how pathetic you are 🙂

  Yes, and are far more stable, not hyped, and are already at pretty much peak congestion. Starlink will get progressively worse, the more people use it. Right now, it’s over provisioned.

  They were not more stable. Any occlusion, including thick clouds, would degrade the signal to being unusable. I used Hughsnet for years, then swapped to cellular (100ms+ latency) and finally to Starlink. Starlink is a pretty solid 100Mb/s, with low jitter, packet loss and latency.

  Ever try a voice call with 30ms of latency?

  Yeah, I use voice chat every day, it’s not noticeable.

    You have the same issue with Starlink…

      No, because the Starlink satellites are 350 miles above the Earth while geosynchronous satellites are 13,000 miles above the earth. Because of the Inverse-Square Law they can transmit a signal that is orders of magnitude stronger.

      In addition, geosync satellites are locked at a single fixed position and received by a single dish antenna so any obstruction along the line will disrupt the signal.

      Starlink’s recievers use a 1200 element x-band phased array so it can lock on to multiple sources and track them as they move across the sky. Each satellite link is its own channel. Losing contact with one satellite simply causes the data to be routed to one of the 4-5 other locked satellites.

      The people on the call do…

      30ms of latency is less than 1/3rd of the latency of most Bluetooth headsets that people use every day to talk on their phones. It is not noticeable at all.

      LMAO you’re really doubling down?

      No, they absolutely will not notice a 30ms delay. Why would you even say something so absurd?
