    Someone really needs to explain the fundamental limitations of shared medium internet connections (pretty much anything wireless) when compared to exclusive medium internet connections (one wire/fiber per end point) to politicians and other decision makers. Banning the advertising of shared medium speeds as if they were exclusively reserved for you would be a good start.

      Oh, I see.

      You think this is a “politicians don’t understand the tech they’re supposed to regulate” issue, and not a “Elon Musk is bribing every greedy asshole in Congress to prop up his businesses at taxpayer expense” issue.

        I think one of the issues with taking bribes is that even corrupt people don’t want to completely ruin the economy because you don’t want the people trying to bribe you lack the money to do so. Or in other words, even apart from any moral issues you don’t want to kill your golden goose.

          Counterpoint: the fact that the moral “don’t kill the goose that lays the golden eggs” even exists is proof that people are indeed greedy and/or stupid enough to do that very thing.

    They were never building that, let’s be honest.

    Edit: rural broadband is like the new affordable housing, high speed rail, or better public transit… It’s something that’s completely possible to do but they’ll always find some excuse to do nothing so they can campaign on it again next cycle

      It was basically up to the states this time around, they could allocate BEAD funds more or less as they wanted and absolutely build fiber out to the vast majority of residences (look at North Dakota, it’s evidently possible) through models like municipal fiber.

      Ultimately it’s a political issue more than anything else, Americans just can’t get anything done anymore, politicians would rather enrich themselves and voters only care about the culture war.

    there’s nothing better than optic fiber because nothing can be faster than light

    Edit: as comment below says optic fiber isn’t actually faster, but still better because it has lower packet loss, is cheaper and not owned by elon musk

      That’s…not really a cogent argument.

      Satellites connect to ground using radio/microwave (or even laser), all of which are electromagnetic radiation and travel at the speed of light (in vacuum).

      Light in a fiber travels much more slowly than in vacuum — light in fiber travels at around 67% the speed of light in vacuum (depends on the fiber). In contrast, signals through cat7 twisted pair (Ethernet) can be north of 75%, and coaxial cable can be north of 80% (even higher for air dielectric). Note that these are all carrying electromagnetic waves, they’re just a) not in free space and b) generally not optical frequency, so we don’t call them light, but they are still governed by the same equations and limitations.

      If you want to get signals from point A to point B fastest (lowest latency), you don’t use fiber, you probably use microwaves: https://arstechnica.com/information-technology/2016/11/private-microwave-networks-financial-hft/

      Finally, the reason fiber is so good is complicated, but has to do with the fact that “physics bandwidth” tends to care about fractional bandwidth (“delta frequency divided by frequency”), whereas “information bandwidth” cares about absolute bandwidth (“delta frequency”), all else being equal (looking at you, SNR). Fiber uses optical frequencies, which can be hundreds of THz — so a tiny fractional bandwidth is a huge absolute bandwidth.

        Microwave point-to-point radios are fastest because they travel through air, but more importantly, are typically the shortest path possible by line-of-sight.

        Being 66.7% of speed of light doesn’t matter terribly when you consider that the cable path is shorter by more than 66.7% of path taken by satelite link.

      I’ve heard starlink is faster than fiber by a few nanoseconds and big finance really wants that for their high-speed trading

      most of its signals move though space, compared to the glass in fiber so it sorta makes sense

        Its not, light is the fastest AND isnt as interuptuble and lag induced as satalite. A wired connection will ALWAYS have lesslatency to a sat link.

          The problem with fiber is it isn’t direct, and the satellites do use lasers (light!) to travel longer distances. The longer the distance the bigger edge satellite internet gets.

    Pros of fibre:

    • cheaper: much cheaper than copper or satellites.
    • faster: latency is faster than copper and wireless (to satellite).
    • very high bandwidth: theoretically unlimited. In practice a commercial fibre optic multicore run for domestic use at street/town level will be pushing ~800Gb/a, and this number generally doubles every few years as tech advances. The new spec being finalised is 1.6Pb/s.
    • high stability: does not give a crap if it’s cloudy, foggy, or rainy, or if the trees have wet leaves, or if it’s just a very humid day, unlike all forms of outdoor wireless comms. Does not care about lightning strikes, as copper does.
    • long life: 25 to 30 years life quoted for most industrial in-ground fibre, but real life span is expected to be much longer based on health checks on deployed cable in countries with large fibre rollouts. Upgradable without replacing the medium throughout that lifecycle.
    • lowest power usage: fibre optic uses far less power and energy than 4G 5G and satellite infrastructure.

    Cons of nationwide fibre:

    • billionaires who launched thousands of satellites make less money.
    • monopoly Internet Service Providers won’t be able to fleece their cable internet customers some of the highest charges for net access in the world.
    • people will tell you “uhm acktually wireless internet is the speed of light also as it communicates via photons”, but will usually leave out all of the interference it experiences.

    There’s nothing better than fibre optic infrastructure for general public Internet connectivity. Wireless/satellite should only be a last resort for remote users.

      As someone who wrote their CS thesis on networks I find starlink infuriating. Its such a terrible option that basically persists through memes and highly niche use anecdotes.

      You can literally cover entire landmass of earth with fiber and cell towers for pennies on a dollar what low orbit satellites would get you.

      Not to mention is objectively better technology which we would have to setup anyways if we want low latency networks and why wouldn’t we want that in the future? There are countless benefits to reduced latency so it’s really unavoidable. Now some want to prioritize worse technology when it’s at peak cost. It’s so fucking stupid.

    Wireless data transmission should only ever be used for nomadic, temporary, and/or sacrificial links.

    They’re useful for quick deployment, but are intrinsically brittle and terrible for resiliency and efficiency.

    The longer the dependence on them for a given use case, the less defensible arguments in support of them become.

    I’m all for the use of satellite delivery of internet services, but only when it’s used in conjunction with a broader roll out of hardwired infrastructure, at which point it can reasonably be relegated to serving as a secondary, backup diverse path.

    Ah yes, who needs fiber when you have an inferior product that will be worse in every calculable way?

    Pay no attention to the person who stands to benefit from this deal. There’s definitely nothing illegal about it.

    So what if the owner of Starlink just happened to spend a quarter of a billion dollars to get the current president elected? That surely has nothing to do with the abysmal Starlink service stealing away funding for critical infrastructure.

    This would be REALLY CORRUPT if the CEO of Starlink was ALSO cutting HUNDREDS of THOUSANDS of American Jobs and SLASHING BILLIONS in Social Funding (like Social Security) just so we could Give Him these CONTRACTS! But FOX NEWS told me that was NOT true so it’s OK!
