Wi-Fi's Biggest Upgrade in Decades is Starting To Arrive (theverge.com) 104

Wi-Fi is about to get a lot better. Many of this year's new phones, laptops, TVs, routers, and more will come with support for Wi-Fi 6E, a new upgrade to Wi-Fi that's essentially like expanding your wireless connection from a two-lane road to an eight-lane highway. From a report: It's the biggest upgrade to Wi-Fi in 20 years, and connections should be faster and a lot more reliable because of it. The Wi-Fi Alliance, the industry-wide group that oversees Wi-Fi, is now starting to certify the first wave of products with support for Wi-Fi 6E. Phones, PCs, and laptops with support should start hitting the market in the first months of 2021, according to the IDC research group, and TVs and VR devices with support are expected to arrive by the middle of the year. Some of the first devices are likely to be announced over the next week.

    is the range the same or is it like 5g where it's less?

      Higher frequencies effectively attenuate more quickly, especially through anything solid. Just like 5 GHz WiFi signals have less range than 2.4 GHz WiFi signals, WiFi signals in the 6 GHz extended band will have even less range. Going from 5 GHz to 6 GHz should be less than going from 2.4 GHz to 5 GHz, but it is likely to be noticeable.

      On the other hand, you are likely to have less co-channel interference, especially at the start of WiFi 6E rollout. This tends to improve range and increase throughput at a fixed distance.

        5G does not mean 5ghz. It means Fifth Generation (which itself is arguable). Most 5G signals are 3.3–4.2 GHz, however its all over the fuckin place [wikipedia.org] including in the 5ghz range.

        I feel like wireless and wifi's use of the letter G is intentionally confusing. Wait until 2 revisions later when we have wifi 6G and things will get really confusing.

          Yes, I know 5G does not mean 5 GHz. But "5G" by itself doesn't have a range issue.

          Millimeter wave (mmWave) 5G runs at 26+ GHz, and has truly terrible range problems. 5G NR at low frequencies (600 MHz) can have better range, and better spectrum efficiency, than 3G and 4G connections. 5G at 3.5 GHz will usually have worse range, because 3G and 4G was mostly between 800 MHz and 2.3 GHz, but 5G base stations are more likely to have MU-MIMO and beamforming, which compensates.

          The next revision of WiFi will likely be branded "WiFi 7", not "WiFi 6F". The "E" is for extension, because it is mostly just adding frequency bands to the baseline standard. It is not a substantial change in protocol like WiFi 5 (802.11ac) to WiFi 6 (802.11ax).

          • Thank you. I was waiting on someone to post the actual ieee number. Things like 802.11ac, 802.3af, etc, are easier for my mind to label than marketing terms like 5G, LTE, and some other intensionally elusive names to sound cutting edge. At least with ieee designators It works a bit like the dewey decimal system. 802.2 and 802.3 specs refer to ethernet framing specs and the physical layers of wired ethernet, while 802.11 specs deal mostly with wireless.

          • Ha, thanks. I had managed to confused the spec 802.11xx with the marketing wifi 6.

        • Wait until 2 revisions later when we have wifi 6G and things will get really confusing.

          Unless they take the same path as USB, in which case "really confusing" would have been a better alternative.

          "Wi-Fi 6GX Ultra Pro Max", anyone?

          • Don't forget USB's habit of renaming older specs, and in a way that makes them sound better "USB 1 is now USB2-Full Speed"

            And I still mix up USB Full Speed and High Speed.

            • "Full speed" has to mean the highest possible speed, otherwise it weren't "full". So "high speed" could be the same as "full speed" or less, but certainly not more.

              Kind of like bicycle wheel rims:
              27.5 inch 29 inch = 28 inch 27 inch

        • I feel like wireless and wifi's use of the letter G is intentionally confusing

          What is confusing about calling Generation? I doesn't say 5GHz. 4G didn't run in 4GHz, 3G didn't run in 3GHz, and GSM or TDMA based Digital (which was 2G) didn't run at 2GHz. These terms have been used for 40 years. People aren't confused, they are at this point willfully ignorant.

    • 5G doesn't have less range. 5G has the same range as 4G when used on the same frequencies.

      Higher frequencies generally have shorter range and less penetration. This is a general property of EM waves and has nothing to do with the protocol that you're using to talk on those frequencies, so although support for higher frequencies was added in 5G and 802.11ax, that doesn't mean that 5G or .11ax have shorter ranges than their respective previous versions.

Furthermore, the 5 GHz band used by WiFi is near the upper range (5.7 to 5.8 GHz roughly), so it's already pretty close to 6 GHz.

          Try this experiment to see for yourself.
          Turn in the light in the room where your WiFi router is.
          Exit the room and close the door.
          Then try using your wifi, from the other side of the wall.

          I think you'll find that the 5 GHz waves from the wifi make it into the next room just fine.
          I think you'll also find that the the 500 THz waves from the lightbulb do not make it into the adjoining room so well.

          The difference is frequency, specifically wavelength vs the size of the molecules obstructing the wave. The lower-frequency waves are longer wavelength. These large waves aren't stopped by small molecules. You can think about a fly in a rainstorm vs a truck in the same rainstorm. A 2mm raindrop will stop a small fly, it won't stop a large truck. Similarly, a 1nm molecule of drywall, humidity, or whatever won't stop a 780 nanometer wave.

          Btw, I'd venture to guess that the majority of people here on Slashdot already knew that in the frequency bands being discussed, higher frequencies have less range, because they are more attenuated by walls, moisture, etc.

            Actually, that's not true. Mosquitos (which are technically small flies) aren't stopped when hit by falling raindrops [smithsonianmag.com]. Otherwise, a monsoon would wipe out malaria in no time...

            • Stop != Kill

              The raindrop normally won't KILL the mosquito, if it has sufficient altitude. That's because the mosquito gets carried along with the raindrop, as opposed to a truck-on-truck impact where both objects slam to a stop.

              It very much stops their progress and sends them rushing toward the ground, however.

      The higher you go in frequency, the better you can make your beam-forming with the same size antenna. In the theoretical limit, range is the same for all practical frequencies. This breaks down if you need to curve around the Earth, bounce on the ionosphere, or go through solid objects (like walls).

      2.5GHz, 5GHz, and 6GHz are about equally lousy at going through walls. The real-world difference in indoor range between 2.5GHz and 5GHz (or 6) is because our 5GHz and 6GHz antennas are not good enough yet.

    The main reason WiFi started out on the 2.4GHz bands, besides that the FCC allowed unlicensed broadcasting on those frequencies, was that it was a high enough frequency to get decent data rates, but low enough that it could pass through moderate obstructions, like walls and floors. Higher frequencies get you faster transmission rates, but lower range through obstructions.

    So, unless they are doing some really weird multi-band spread-spectrum thing, I'm not sure how adding another higher-frequency band is going make WiFi connections more reliable. To extend the highway analogy, adding more super high-speed lanes doesn't help when they are prone to flooding all the time.

      In crowded urban areas, and especially high-rise apartment buildings, a lot of AP's in close proximity end up using the same channels and interfering with each other. And with that density of AP's, even frequency-hopping would still result in overlap. 6E could help in two ways. First, it provides a bigger pool of channels, therefore the likelihood of mutual interference is less. Second, its reduced range lowers the physical area over which one AP can interfere with another.

Higher frequencies get you faster transmission rates, but lower range through obstructions.

      WiFi started out in two bands - 900 MHz and 2.4 GHz. Both bands were (and still are) classified as "Industrial, Scientific and Medical" (ISM) bands. This means tha there are devices that emit RF in these bands for purposes other than communications. The 900 MHz band was also used for location determination (e.g. LoJack) and paging, if I recall.

      These are U.S. designations I'm talking about. The 2.4 GHz band is and always has been pretty much global, but the 900 MHz band is more U.S. than anywhere else.

      The 900 MHz band also was home to "diathermy machines" (medical equipment that performed heating by RF). The 2.4 GHz band is home to one very common non-communications RF emitter - microwave ovens. Did you know that microwave ovens only emit RF half of the time? Every 1/60th of a second (US, 1/50th of a second in Europe etc.) the magnetron turns on and emits RF. The other half of the AC wave cycle time the magnetron is off. WiFi was specifically designed to accommodate this and will transmit information during the time that a microwave oven is not emitting RF. In effect, WiFi devices synchronize their transmissions to slip into the "off" times of the microwave oven duty cycle. This works fine unless you have two microwave ovens operating at the same time, but on opposite phases of the AC power. This can happen for instance in restaurants. In 1999/2000 I lived in a small town and used WiFi for Internet. The antenna-to-antenna distance was only about 1/4 mile. But I had the misfortune of the ISP's base station being in the same building with a restaurant. I learned that I could fairly reliably count on the Internet being unusable from about 11 AM to 2 PM, which I attrributed to the restaurant "firing up the microwaves."

      I guess I should stop posting and go back to bed, but this tickled my nostalgia nerve, seeing as I served on the 802.11 committee during its first two years.

It's no coincidence that these are also the frequencies used by cordless phones. Nearly the rest of the spectrum rights had already been sold. At least in ranges of spectrum that had good coverage for a first generation of wireless.

      Can you imagine coordinating the buybacks or forfeitures of spectrum all over the world? And that for 2.4GHz, where you'd

  • Any reduction in latency by any chance? Using more lanes sounds like it could create more delay just in order to establish and coordinate all 8 channels opposed to only 2.

    Is Bandwidth seriously the problem facing WiFi? Has gigabit+ home internet become so commonplace that the wireless connection is now the bandwidth limit? Are there really admins out there running 50+ wireless clients per access point that think that everyone videoconferencing at the same time with great quality is something that can happen if you just get ENOUGH bandwidth?

    Am I the only person in the world who's problems with WiFi are easy hand-off roaming? Multiple AP overlap management? An authentication scheme that doesn't rely on passwords stored in plaintext or a preexisting PKI? Ability to penetrate a sturdy houseplant? Smart spectrum allocation that doesn't flip-flop constantly? Hell, how about just a high-certainty quality of service?

    Wake me up when the next WiFi sales pitch is '100Mbps, with a QoS of Fast Ethernet. THAT would be revolutionary.

      Wake me up when the next WiFi sales pitch is '100Mbps, with a QoS of Fast Ethernet. THAT would be revolutionary.

      Well, most of those problems you list have already been solved. 802.11k, 802.11r, 802.11v. These days they are really easy to deploy for example with Cisco Mobility Express. Just buy a bunch of APs, configure one of them and set it up in your network, then just connect the rest to the same switch. They'll connect to the first AP and get settings from there. If you need to manage across multiple sites, then just get a controller.

      For the QoS - well, 802.11e has been a thing for years, but Wifi 6 actually *does* something in that regard. Instead of the older spec where the illusion of QoS is created due to "higher priority traffic uses smaller inter-frame gap" (and it works to a degree) with Wifi 6 you actually can allocate dedicated sub-channels for each client. No more collisions.

      Of course this doesn't really work until legacy clients are gone, but in enterprise environments you can probably enforce that as part of your normal equipment life cycle.

    • "Ability to penetrate a sturdy houseplant?"

      This. As someone who lives in a late-50s house with real lathe and plaster walls, I feel your pain, or at least lack of signal.

      And the comment started my day with a chuckle matched only by Calvin's snow goon problems.

      • As someone who has plaster-on-drywall walls (About an inch or more of solid rock, basically), it's rough getting ethernet cables run. Worse because I have a fairly inaccessible attic and drywall ceilings in the basement. But it's worth it.

    • You're probably one of them ne'er-do-well Luddite-types who also don't want thinner smartphones and non-removable batteries...it's the future, man!
    • Maybe you should, oh, actually read up on 6E to see what it actually does before wildly spewing your irrelevant diatribe. 6E brings additional spectrum capacity through contiguous spectrum blocks, which accommodate 14 additional 80 MHz channels or seven additional 160 MHz wide channels. Along with the features from WiFi 6, this will address most, if not all, of your supposed "issues". You're probably sitting there with a 802.11b router wondering why your YouTube keeps buffering.

        Classic /. poster. Doesn't bother understanding who he's responding to, doesn't bother understanding what he's talking about, lets petty insults do his talking. The problem with modern communications is that it enables people like you.

    • I think you are the only person because we have solutions for the problems you listed in existing wireless standards. You just have to not "invest" in cheap Chinese routers.

    • Has gigabit+ home internet become so commonplace that the wireless connection is now the bandwidth limit?

      Yes, and that has been the case for years.

    • by dfghjk ( 711126 )

      No, it's not at least for residential. You've summed it up pretty well.

      • So by saying "for residential" you're actually saying yes rather than no. Because all of the GP's problems have been solved and all users need to do is buy something other than Chairman Xi's favourite exported wifi access point.

        The standard does not exist to mandate away cheap devices.

Are there really admins out there running 50+ wireless clients per access point that think that everyone videoconferencing at the same time with great quality is something that can happen if you just get ENOUGH bandwidth?

      Yes. On our office (pre-COVID), a huge percentage of our traffic is wireless and to servers on the network. For the dev-team, probably 75% of the traffic never left the building (local app servers, version control, DBs, etc). You want to do all you can to avoid them making the non-engineering team suffer.

      Also, please consider that my company and many like us are moving to apple products where Jony Ive's sometimes great, but sometimes horrific design sentiment legacy has determined that wires are bad. Thus...every apple user needs a wireless mouse and wireless keyboard and Apple stopped making officially supported ethernet adapters long ago. I hate being a luddite, but I fucking love wires. I like things reliable, cheap, and efficient and I never really though a keyboard on my desk was a scenario where wires were a hassle...same with mice. However, try telling an Apple loyalist to go 3rd party....to them, it's like smearing crayons all over their perfect gucci handbags. They really take it personally and have to be Apple purists and our tech support is hesitant to go 3rd party for mission critical functions. I think of the ecological impact...a wire transmits signal reliably and nearly perfectly with less electricity/interference/error than wireless, but in my office, few think like me.

      So...while if common sense ruled, we'd all be on a wired connection at our desk and wireless in a conference room, Apple's penetration has moved most traffic to wireless...also video streamers tend to rely on wireless more than wired, so both home and office have a lot more wireless than wired traffic in most cases.

      Also, remember that's maximum bandwidth. Do you really get maximum bandwidth at most places in your house? I'm excited for next gen WiFi for range boost alone. However, the devil is in the details. I've been fooled many times in the past by promises of theoretical greatness that never really materialized in reality. I think bandwidth is one of those things you never can really have enough of. At the very least, it means you can spend less time on the network if you can complete your downloads faster.

      In crowded areas, yes. An apartment block with 20+ networks visible isn't going to get good bandwidth at all - not because of interference, but because of sharing. Interference leads to no one getting any bandwidth, but stations and networks using the same channels do listen for each other and avoid trying to interfere with each other so at least some traff

  • It is still the same spectrum, that everyone wants to broadcast on. If only the backhaul would allow to distribute connections in a private matter over multiple independent access point owners, sharing of this precious space would work much better.

    I thought we were supposed to move to representing advances in an incremental manner, eschewing suffixes like meaningless tacked-on letters.

  • Bandwidth equates to more error, since my wireless network at home is used for internet, I don't need really fast speeds so I run 11Mbit/sec which seems to have a better error rate. If I do need speed I use wires and significantly lower the possibility of error or latency issues.

  • Sure, on your LAN you'll have faster access... if you're in the right place with the right (new expensive) gear.

    But none of that will change your Internet connection speeds, which in the US is slow and expensive.

    Save your money. Even 802.11ac from 2013 (450Mbps) is fast enough to support streaming 1080p, playing your Spotify stuff, and downloading "the entire Encyclopedia Britannica" (how is that even a standard of measurement anymore) in no time.

  • Also the higher the carrier frequency, the more obstacles in it's way attenuate the signal -- like the walls in your house, for instance.
    Let's face it: WiFi was never all that great and they keep putting band-aids on it to shore it up. If you want reliable speed you need wired ethernet.
  • I remember when that happened to I-270 outside DC. More traffic, more gridlock, more development, more accidents. Fun stuff...
  • The article is long on hype and short on detail. And it makes sense that there's a lot of skeptical posts here; increases in theoretical bandwidth with past WiFi standards often didn't translate to large real-world improvements.

    But here's the thing: beyond just adding more available bandwidth, 6GHz will be unoccupied by any older clients, so the features of 802.11ax can really come into play. The better modulation scheme (OFDMA) and improved efficiency of 802.11ax can result in roughly 4x improvements in bo
