This is a most excellent place for technology news and articles.
The renewed focus on reliability is motivated by emerging applications. Imagine a wireless factory robot in a situation where a worker suddenly steps in front of it and the robot needs to make an immediate decision.
This example is a real WTF. I really hope nobody is planning on building safety-critical real-time systems on top of WiFi!
I imagine many already exist. But the system should be designed to fail safe with WiFi in mind.
I don't know about manufacturing environments but I deal with laboratories a lot, and I'm a bit baffled at how quickly lab operators have jumped on battery-operated wifi sensors for lab monitoring systems. I have like three room sensors attached to my EcoBee thermostat at home and I can barely be assed to change the batteries in those things, I cannot imagine dealing with batteries and connectivity troubleshooting for a building full of sensors whose reliable operation is often critical for regulatory compliance. Seems like the perfect application for PoE systems, to me
In industrial there are very few wireless systems unless they are either too remote from the CPU and aren't safety sensitive. Safety is taken very seriously because any incident can mean injuries/death and ending up in the public eye. Any safety systems are hard wired because of reliability.
I really hope nobody is planning on building safety-critical real-time systems on top of WiFi!
Are you new to the planet? Let me tell you about this thing we have called capitalism...
Better hope staff don’t Microwave their lunch at the wrong time….
This sounds like they're talking about something specific. There was a guy that was picked up/crushed by a robot recently that is eerily similar.
I work in autonomous vehicle engineering. That's not even on the table for something we'd consider doing. But China is trying to enter the market hard, and I am less sure they wouldnt do that.
I'm guessing the bump to 6GHz means range is even lower. Seems we're leaning towards a future of hardwired-equivalent speed and reliability... within 1 meter.
Then you can buy a bunch of repeaters and the economy is saved
I know this is a joke but please do not buy repeaters they do not work how you would expect them to work.
Repeaters take an already weak signal and amplify that signal while increasing the latency. Sure this makes the signal go farther but it doesn't increase the bandwidth and if you stand in between the originating wifi source and the repeater your device may not migrate to the source wifi even though it might be faster because the reapeter has the illusion of being a better signal because it's louder.
The better route to go is to use multiple wifi APs through out the building connected back to your router with ethernet.
You could also go with mesh access points but you have to do a lot of research and planning; The two key things to look out for is they mesh system must have a dedicated backhaul and you must place them where each node has an excellent signal to the next node. Since most backhauls run on 5Ghz and 6Ghz this means there shouldn't be any walls between them.
Exactly. I'm going to be running Ethernet through my house soon, and even if we stay full Wi-Fi, we'll benefit by having physical cables connecting the APs. I already have a separate AP, just need to run the cables to get a second in our basement where the signal is weak.
Do yourself a favor and drop fiber at the same time. That's my plan for whenever I get around to crawling in the attic.
Is fiber really worth the extra complexity and expense? It's strength is in longer distances with mostly straight runs. When you are doing short distances with multiple turns, copper is much easier and more forgiving. Splicing fiber is difficult if something breaks during or after installation, on top of the expense and skill needed for proper termination. Tools and hardware for copper are cheap, easy to use, and ubiquitous.
Why would you drop fiber when you can do 10gbps on ethernet at the distances most cabling would be in a home. Never would consider to run fiber and I just finished a couple of new cat7 drops in my home.
We have the luxury of having 1, 2.5, 10 and 25 gigabit fiber to the home but I haven't considered even 2.5 until the services I use can leverage it
Yes but WiFi 7 FINALLY lets devices connect to multiple BANDS at the same time with a new feature called Multi-link operation (MLO).. IE the device can hold on to a longer range but slower band and more seamlessly transmit data over the best one at the time.
That's an advantage if you utilize it right. Less range means your neighbor's wifi is less likely to interfere with your own. Multiple access points are a superior way to get coverage of your whole house than some octopus antenna monstrosity.
The inverse square law doesn't have to be a problem.
I think the prevalence of mesh systems is intended to remedy this. Instead of a single AP that can cover your entire house you can mesh two or three (or more) APs to get the coverage desired.
That's how I do it, except because I have all these AP's I just set them up near the devices that will use it and plug them all into the AP's and use the backhaul which is way more reliable. Phones and tablets are the only things that use the wifi and never really found an issue with speed or reliability since moving to mesh.
Fighting games with Wi-Fi instead of Ethernet? Sounds more like a dream. This genre is particularly demanding on stable low latency connections and current technology absolutely doesn't offer it. Spreading across frequencies sounds like a latency vs reliability trade-off.
Back when 5G cellular was first rolling out, a professor brought in a Qualcomm senior level manager and the topic was how 6G was being developed for long distance low latency capabilities.
How much of that was industry bullshit, no idea but it sounds like they had a pulse on the tech now that we hear about it years later.
The lowest latency links right now are already wireless point to point links.
I feel like this is really dependent upon the game. Guilty Gear Strive for instance uses roll back net code and my personal experience playing it online over wifi is that it feels practically identical to playing locally. Here and there I might have minor issues if the person I'm playing against has horrible Ping but for the most part wifi is flawless.
In theory the speed of light is higher in free space than it is in copper.
Glad to see stability and QoS being prioritised over throughput this time around. I feel like once WiFi broke through the 300 Mbps barrier with the 5GHz band, strictly focusing on further improvements in throughput would just yield diminishing returns for most people.
However, latency and signal strength have been notoriously annoying long-term problems that I'm happy to see finally being acknowledged.
I work with WiFi all the time and let me tell you that after looking at usage graphs for what feels like forever, you don't need 1Gbps WiFi.
Most clients aren't averaging 50Mbps, nevermind 500-1000. What you want is consistent wifi. Something that doesn't show down because you dumped everything and the kitchen sink onto it. There's a lot of good ways to ensure this and nobody wants to pay for it.
Simply put, dumping 30-50 client devices, between cellphones, tablets, laptops, TVs, gaming consoles, IoT things (like smart lightbulbs, fridges, etc), and in more cases than I'd like to admit, desktops... Onto a single multifunction wireless router, with little more than dual band WiFi, is generally going to suck.
I usually hear a chorus of responses to this because people don't really put together that their smart watch, Alexa, smart smoke detectors and thermostats, all count as wifi devices. It usually doesn't make a huge difference how much each device is actually using the wifi, the fact that all of them are connected at the same time is, in and of itself, a problem with only a single access point where that contact can be made.... Dual band or not.
I don't consider mesh solutions to be solving the core issue since all of the client traffic needs to end up at a single device with all the same problems. The fact that they get filtered through what is essentially, fancy repeaters, isn't super relevant. The problem still exists. But if you suggest an infrastructure network with multiple wired access points, people generally take one look at the price, then leave and go buy the latest night hawk from Netgear at the nearest electronics store and put it out of their mind, since it's "good enough" (which it isn't, in the current WiFi climate).
I want people to have better wifi, but I can't save you all from yourselves. Now the IEEE is taking on the job, I suppose. Trying to "fix" wifi because most people can't be arsed to install a reasonable solution for what they actually need. They'd rather spend literally thousands of dollars a year on fast internet service that they don't need and can't use because it's all getting filtered through their sub $300 network that they've had (or will have) for two+ years, and then have the gall to complain that their wifi sucks, and they don't get it because they're paying $100+ a month for their fancy gigabit or multi-gigabit internet connection.
I agree when it comes to average usage, but having >=1Gbps headroom for bursty traffic, e.g., when moving files locally between devices, is awesome.
You seem to really know your shit. I'm realistic about my WAN speed needs (symmetrical 350 Mbps is more than sufficient) - but I'm pretty tired of my shitty Netgear setup. I'm not really sure what I need LAN wise, and the price tags of Ubiquiti/UniFi systems have me worried about buying more than I really need. I know pfsense/opnsense can be useful alternatives to start with in minimizing prices, but the steep learning curve has me a bit intimidated.
Do you have a suggestion or recommendation on where to start? Is there something that's functional at a sub ~$500 initial investment, but would be upgradeable/expandable and ultimately more reliable/dependable in the long run? Do I need to wait for this wifi7 gimmick?
Thanks mate.
Is this supposed to be the wi-fi standard that would allow for wireless VR? I'd love to have a standard that makes such a setup possible.
Wireless VR has been a thing since wifi 5ghz. And from first hand experience, it works great.
If you can work through all of the weird issues it works great, but it can definitely be finicky to setup for some people. Im in an apartment and the wifi in 5ghz range is so congested i had stuttering every few seconds. Had to switch to use DFS and it was super smooth after that.
Yeah, but you'll need to be within 5 feet of the access point. I kid, but i am curious how range will be.
Good. I almost never need speeds in excess of those possible with WiFi 2, and 90% of the time WiFi 1 speeds are enough, but very often my speeds drop below 1mbps, rendering accessing the Internet on my phone or tablet essentially useless.
Currently gigabit Ethernet is faster and more reliable than WiFi, despite WiFi theoretically being equivalent. The benefit of increased speed and scalability is never needing wired infrastructure at the home/office.
We’re in a race: on one side WiFi7 had great potential, but on the other side 2.5gE is becoming more common on new PCs. Who will win? Will consumers care, if they don’t have a home lab and can’t get an internet connection to match?
For those claiming current bandwidth is more than people need, I would agree in theory but it just doesn’t pan out in reality. There are always network glitches and irregularities, there’s ever more tracking and advertising, there’s ever more Interference.
Recently my fiber provider had issues and my connection was downgraded to 350/150 with 44ms: theoretically still way faster than I need yet even “simple” web pages were noticeably slower.maybe I’m spoiled but I couldn’t imagine trying to game on that
I resent wireless because I feel like we got led astray by the aesthetics crowd. It was never good-- contested bandwidth, poor penetration, paper-mache security, but it was so much more attractive than cables asunder that we're throwing moonshot resources at it to try to make it good enough.
Meanwhile, consumer wired has stagnated. You can finally get 2.5GbE on a lot of new mainboards, but there are few affordable home router/AP devices, especially with multiple 2.5G ports. the local home centres still primarily stock spools of Cat5E, and even new-build developments treat networking as a low-priority line item, probably well below cable TV jacks, if they mention it at all.
If we had put the same emphasis on wired, there'd be 10/40Gb fibre NICs in commodity systems, and the Home Despot would sell all-inclusive fibre and Cat6A or 8 retrofit box kits.
My SFP 10GbE equipment was cheaper than the 1GbE equipment I installed 15 years ago. You can absolutely set up a home fiber network affordably if you want, NICs for tower hardware isn't even the issue - even SFP USB dongles are widely available and not that expensive.
I switched my house to 10gbe & 2.5gbe and never looked back. Not only is it fast, it's so much more stable. I still have 1gbe for things like PoE cameras but man. My network is rock solid.
You might just have a crappy router in general...? Not as in, you need the newest router with fastest speeds to tide over the slower times. What I mean is that there's lots of cheap, no-name routers that are just extremely unreliable. Many ISPs hand them out.
Investing into a more expensive router from a widely known brand is usually well worth the money, in my experience. You can probably even buy a used one and still have a better experience.
I'd honestly like distance and stability crossed. Shorter distance than wifi6 isn't very useful at least at my house where one wall seems to block most of the signal.
By time I'm at my garage it's all 2.4g.
