    Ensuring that the system complies with industry standards and integrating security measures for cross-technology communication are also necessary steps, Gao adds.

    This is absolutely a huge factor that could make or break the technology if they don’t do this perfectly. This could be the single most important part of the tech.

    2.4 GHz is super saturated. The last thing we need is long range i.e. large footprint signals in already saturated spectrum. How this technology is deployed should either be not at all, or very carefully, to prevent widespread interference with existing WiFi devices. This spectrum is already on the verge of being complete trash. Please please do not be deploying more stuff on 2.4 spanning an entire “smart city.”

      This spectrum is already on the verge of being complete trash.

      Radio shouldn’t be used when avoidable. It’s for emergencies, aviation, hiking, short-range communication for convenience maybe. Phones - yes.

      But providing internet connectivity via radio when you can lay cable is just stupid.

        I mostly agree with you. I find it really weird how I live in a world where all my Internet is being run through 5G cellular for political and social reasons and not for technical ones. Due to the monopoly on the cables, it’s actually much cheaper here to buy 5G home internet. It seems unnecessarily complicated and choosing to use a shared medium for no reason. It’s just the politics.

        In case you’re not from the States, we have a monopoly pretty much everywhere for Internet services.

        With my 5G I have unlimited data, and it’s 300 down 44 up on a good day. It’s perfectly serviceable if you can live with increased latency.

      I actually ditched 2.4 gigahertz Wi-Fi on my home network entirely for this exact reason. If a device is not compatible with 5 gigahertz Wi-Fi, it doesn’t get purchased.

        Do you live in a high density urban environment?

        Because if so, that totally makes sense, and the other benefit of 5GHz/6GHz not traveling too far outside your apartment or condo wall, is pretty nifty as well.

        But if you live in a house in the suburbs, man, that is commitment well outside of necessity, or convenience. Not saying it’s bad choice per se, just seems unnecessarily burdensome IMO.

          I live in a single family house, but the area has quite a few single family houses packed pretty close together. So there’s still a lot of traffic on 2.4 GHz.

          In my experience, having a vr setup with vive body trackers consumes the 2.4ghz band really fast; so there are still reasons to swap in the suburbs, but they’re more niche.

          Source: my PC is too far away from the router for wired, so it uses wifi. I had to switch to using 5ghz because my internet would drop out on 2.4ghz whenever I played VRChat.

        It doesn’t just benefit you. You’re benefiting the current users of that spectrum that for one reason or another might not be able to switch.

        I suspect most users though couldn’t tell you what frequency their network uses let alone the devices on it.

      Sounds like they basically crafted some special messages such that it’s nonsense at 2.4ghz but smoothes out to a LoRa message on a much much lower frequency band (<ghz).

        It’s LoRa on 2.4ghz.
        It’s just that chirp signals are easy to decode from a lot of noise.
        And they don’t really affect most other modulation techniques. I think you can even have multiple CSS coded signals on the same frequency, as long as they are configured slightly differently.

        LoRa is incredibly resilient.
        It’s just really really slow

          I don’t think it’s “just” LoRa on 2.4ghz, because if it were existing lora devices wouldn’t be able to decode the signals off the shelf, as the article claims. From the perspective of the receiver, the messages must “appear” to be in a LoRa band, right?

          How do you make a device who’s hardware operates in one frequency band emulate messages in a different band? I think that’s the nature of this research.

          And like, we already know how to do that in the general sense. For all intents and purposes, that’s what AM radio does. Just hacking a specific peice of consumer hardware to do it entirely software side becomes the research paper.

    Maybe I’m being overly paranoid (this is Lemmy, after all), but doesn’t this seem like a step toward something troubling?

    1. Almost all of our devices are designed to use WiFi. Just try finding a laptop with an ethernet port, or a phone or tablet with wired connectivity. You can get adapters, sure, but they’re not standard anymore. I wouldn’t be surprised if game consoles eventually drop wired options altogether, or charge extra for them—like Sony does with the PS5 disc drive.
    2. ISPs have a track record of trying to control our internet experience—remember the fight over net neutrality? They’re always looking for ways to monetize data and restrict what we can access online.
    3. With long-range WiFi on the horizon, ISPs might find it cheaper to install one powerful broadcast device per neighborhood, similar to how 5G towers are deployed.
    4. And when that happens, it’s not that features like fiber to the home or port forwarding are gone, but they could be locked behind an extra fee. Want direct access to your own network settings? That might come at a premium. Even access to certain websites could become conditional on paying more, or worse, dictated by someone else’s agenda.

      They can do that right now. If this new wireless option is standardized, it would seem less prone to ISP shenanigans to me. Just a question whatever functionality makes it into the standard in the first place.

      What are you talking about?

      This is not about streaming to a laptop or Internet access. This is about a long range, low power, low bandwidth network using 2.4GHz. It’s using 2.4GHz, like everyone else likes to, because it’s the “free” signal band that you don’t have to pay to license. It’s for sending the message “Sprinkler head 1039A is leaking” from a solar panel powered transmitter without having to run a data cable or network repeaters.

      It’s competition for Zigbee/Z-Wave/Matter. Not the herald of the ISP crackdown Armageddon.

      Laptops with Ethernet are still pretty common. I just bought one recently. At work, we buy a lot of them. But I don’t think smartphones ever had integrated wired networking.

      But that aside, what you’re describing is already happening. Wireless network deployments are much, much cheaper than running wire to each building. In semi-rural areas, WiSPs are pretty common. And 5G for home Internet access is pretty common in high-coverage areas. And as time goes on, the ISP-provided equipment is more locked down.

      But I don’t think those things are related.

        Not in the US, but every LTE home internet provider I’ve dealt with is just a SIM that you can use in any off the shelf LTE/5G to wifi router setup. Mikrotik options are cheap and can handle simple one-device implementations, and multi-device mesh setups (that require more effort to configure)

      I think the article is explaining that this is really just modifying wifi protocols to work over LoRa, to reduce LoRa costs.

      This will probably only be beneficial to people currently using LoRa.

        I thought that LORA was optimized for low data throughput? Running WIFI over such a link would suck.

      Just tell them you have a low packet loss tolerance. The wire will never be cut. It can’t replace a wire for many use cases

      I can find this believable in the US maybe (only stayed there for a few months and I heard nothing good, data caps on broadband is wild) but not a chance in countries with stricter regulations and guidelines on what the ISPs are allowed to do.

    I’m kinda looking forward to seeing how this pans out. Personally, I’d want to use it to make small, local hobby networks; kinda like how it used to be that basically anyone with a phone line could start an ISP.

    No thanks! 👍 Is there any way we could make a standard where unknown servers trying to run apps from google locally on my devices could be auto blocked? I’d love a standard like that.

    "Hey we removed Google photos since they turned on the camera without your consent. We did that remotely! While you were out "

    That WiFi, I would like.
