Companies like Unifi have only just released their Wi-Fi 6 APs (I think). It feels like we've only just got Wi-Fi 6, and adoption rates in my home and office are currently very low. Perfectly working AC AP's are not going to be upgraded for years!

I believe a new 6E standard is supposed to be rolling out as well.

  6E is basically the same as 6, but with more frequencies available so more devices can operate without interfering. Could be a nice upgrade in a crowded environment, but in many cases I can see why people would skip it.

    Yup, 6 GHz

WiFi 7 proposed bandwidth is just bonkers - 40G. I’d imagine that we’ll see new wireless applications like wireless docking, displays, etc.

  40G over what distance, three inches?

    Within the same room at least, the big catch is that that’s with 16 spatial streams. A more likely 2 streams would top out at 5gbps link rate, and somewhere around 3gbps of real throughput. Then the only real caveat is that you’re using 2/7 (or 2/3 in the EU) of the allocated 6ghz spectrum, but that’s workable given the range of 6ghz.

  Not that new – WiGig has been used for VR (i.e. displays but head-mounted): https://www.vive.com/us/accessory/wireless-adapter/ https://www.vive.com/us/accessory/wireless-adapter/

    Apples to oranges, very different characteristics. WiGig (802.11ad)'s up in the 60GHz band where even the oxygen in the air is absorptive, I think most walls pose big problems. But there's 6 channels of bandwidth each with 2160 MHz of space. Wifi by compare recently went from 480 MHz of space (5GHz) to 1600 MHz (+6E spectrum) of space available in total. Colossal gain, nearly tripled in bandwidth. But there's still less bandwidth in all wifi than there is in a single wigig channel. That wifi is making such excellent use of such a relatively limited amount of spectrum is amazing. I'm expecting impressive connectivity even at significantly reduced link budgets. But as for the point here, about interesting new inter-device connectivity, I agree with both of you. Wigig did have these capabilities, has had interesting video & device shipping for a while now. Alas adoption has been just critically low. VR was basically the only thing that pulled this impressive wigig standard out of the hole it had crawled in to die. No one was building this stuff. Huge loss, huge pity. I really wish we had a lot more experience using wigig like technologies, because to the grandparent posters point, having this massive connectivity capability on tap for everyday consumer & business wifi: it's definitely going to enable intense new streaming & inter-system capabilities. I just wish we'd gotten more of a chance to explore this space more freely in the past 10 years, which is about how long 802.11ad/wigig's been around for.

Wrong. WiFi 7 has some cool stuff for location tracking. From a previous post. https://staceyoniot.com/the-next-big-wi-fi-standard-is-for-sensing-not-communication/ https://staceyoniot.com/the-next-big-wi-fi-standard-is-for-s... You will see WiFi 7 rollout heavily in business due to its benefit for real time asset tracking. Think warehouses, hospitals, education campuses, industrial plants. Location based asset tracking in real time has a great ROI in these areas to name a few. Its gonna be awesome.

    This, along with facial recognition, needs to be made illegial in every state.

      Disagree. Selling devices that you don't own and you cannot control (ie disalbe WiFi chip so tracking is not possible) should be the illegal part.

        That's orthogonal to the issue, you don't need to make a technology illegal to make an application illegal.

        Why not both?
  - jmartrican 5y ago
    i thought the consumers were the assets being tracked.
