You mention meshtaatic. There is also halow on the consumer side now. One of my goals for the next year is to set up a few open halow nodes in a mesh. As a local anarchist community network of sorts. With little or no intention of bridging it to the internet. Outside of connecting to other similar remote network segments or maybe an email/xmpp bridge. Mostly a separate local network with separate local resources.

    Like every protocol in the unlicensed 900mhz range, 802.11ah has a very limited transmission rate in the 50 to 100 kbps range.good for occasional data like sensors or a few bytes of message, but not for any modern comma like AV, mass file transfer, etc.

    Wi-Fi HaLow data rates range from 150Kbps to over 15Mbps, over 600 times faster than LoRaWAN while still achieving good range.

    It will of course varry by environment, topology, and configuration. As everything does. But even a megabit, 125KB/s leveraging modern technologies. Would be very usable. Capable of pushing DVD level streams of AV1 and opus though at saturation. More than easily able to push basic websites. High traffic probably not. But I wouldn't expect neighborhood/village traffic to be too heavy.

    I've been watching halow for a while, I haven't yet seen any sustainable, real-world examples beyond a few hundred kbps (not bytes). I have seen the 1Mbps results, and they're promising, but most places with any other traffic in the free band is busy. If you have any successful and repeatable tests hitting at usable speeds, I'd love to see them.

    After getting into meshtastic and a few other lorawan projects, I'm a bit concerned that tests for these are always high and visible, which doesn't work well in the mountains, even at shorter ranges.

    I used to be more hands-on with these new standards, but I'll wait for better tests to come from halow before I try it out.

    I've seen one. Not a great sample size. A YouTuber who also does a lot of mesh-tastic videos. Demonstrated live streaming from an ESP32 camera module in a large public park. High resolution low frame rate. As well as in a bridge configuration streaming YouTube from their apartment close to practical range limits. Roughly line of sight, minimal obstruction, of course.

    Guaranteed success? No. But definitely something worth looking into investigating and replicating. Devices like these are much more accessible to your average person than ham certification and equipment.

    I appreciate the response.

    I'm still keeping an eye on these technologies and I hope we can set some decent standards for alternates to WiFi and LTE narrow band.

    No worries. And I remembered the youtubers name. Data Slayer. He's got a few halow videos. 1Km and several Mbps is just about the baseline to be interesting. Lorawan range is great. But the data rate really is far too low for anything outside iot or im.

    Some of the heletech modules look very promising and not unaffordable.
