Nice, but don't forget that LoRa® LoRaWAN® and The Things Network® is all proprietary and patented stuff. The article is advertising.

You can get a LoRa transmitter/receiver for like $5 and setup your own network. Documentation and datasheets are freely available. They are really not printing money with that technology. There isn't any opensource modulation scheme that comes even close to LoRa.

> They are really not printing money with that technology.

Not until it becomes widespread. For-profit companies are not charities and they patent things for a reason.

Posting ones own content is not astroturfing unless they try to hide that it was them.

The submitter is a low karma anonymous account that just so happens to match the last name of the CEO of the company, so it isn't disclosed. Also this shot up on the 'new' page suggesting more than one company vote, this isn't the first time this happens with that particular domain either. Similar stuff is happening on Wikipedia, read the talk page there (and the LoRa page) to see what I'm getting at.

Are comments really the best place to hash this out?

Why not just flag and move on.

People don't need to disclose who they are when submitting things to HN.

Hell, I used to have a pretty comprehensive bio, until I replaced it with an icloud relay email because random internet people would look me up outside HN and try to dig up stuff to use as ammo in response to comments I posted that they disagreed with.

HN can be a nasty place. I don't fault anyone for hiding their identity.

That's a neat idea. The challenge will be to stop it from becoming a huge success because then you get all of the problems that are endemic on the normal internet as well. But that sounds like a very interesting and worthwhile project.

There are already 89 gateways in Vienna you can directly use. So nothing is holding you back :) https://www.thethingsnetwork.org/community/vienna/

This is a truly awesome resource - thanks for sharing that! I'll be getting the retro computing crew, that is forming around our new exhibit at the Retro Gaming Museum, excited about this!

Who knows, maybe we will have a retro- net up and running in the next few days ..

Yeah... But WiFi doesn't work when I'm sitting on the toilet two rooms down the corridor. Crazy times. No, to be honest: Very impressive. It's kind of a "dream" of me, to bring Internet to the river/picknick area two kilometers away from me. LoRa would probably be the way to go, will have to look further into that.

Define "internet". LoRA is more like an occasional SMS service than a network connection, so I doubt you could get the average modern 100 MB website to render through it. Would be more practical to get a Starlink dish set up or a directional wifi antenna on both ends, those can do a few km on a good day.

Or just you know, use the 4G that is probably there already.

Jacques’ point is spot-on. What word would be more precise? shilling? spam? The word astroturfing seems fine to me

If the content is good and nobody is hiding their affiliation with it then the correct word is just "posting". Otherwise it might fit within one of the categories you mentioned.

I agree that it would be better if they were up front with their affiliation, but hiding it (astroturfing) is not the same as not divulging.

It can bounce off of meteor trails or the moon. It's been done many times in the ham community. Signals do bounce off of aircraft too, there are even passive military radars that track airborne objects using DVB-T or other strong signal reflections. It could be used if the conditions are just right. All of this has really nothing to do with LoRa and everything to do with physical properties of the emissions (frequenc…

Yes, of course this is related to the physical properties of the emissions, but LoRa uses specific frequencies of the ISM band (868 MHz in Europe), and this discussion was about the reasons why that specific LoRa transmission worked even though there wasn't a line of sight. Airplanes could be an explanation, although your sibling comment thinks there isn't sufficient transmission power for it to be feasible.

Ah. It's most likely tropospheric ducting, I thought the top comment explained it.

There is never any mention of bitrate when talking about LoRa. It's infuriating from someone on the outside.

From what I gather, the map says a "SF:12" which means a spread factor of 12, at a bandwidth of 125khz. With a code rate of '1' according to https://www.rfwireless-world.com/calculators/LoRa-Data-Rate-...

this means about 292 bits-per-second transmission rate for the packet. But I'm unsure if this is correct.

How hard would it have been to put that in the post? I feel like there is some conspiracy to never talk about bitrates/transfer rates in the LoRa world. Like, ever.

Just say it. It helps people understand what this tech is for.

Yeah... Projects like open WiFi are probably becoming less and less useful, as everybody is carrying 4G/5G modems in their pocket.

How would that exactly work?

I did this once as a small experiment. Basically use a small TCP stack with LoRa as layer 1 and then expose the whole thing as a Linux kernel module. It was a bit shitty but it seemed promising. For some reason, I don't find LoRaWan at all alluring. As far as I can tell, in the end it's in the hands of one company and that really defeats the spirit for me. I mostly just use LoRa for point-to-point connections with my…

That is pretty cool. You might want to try again with 2.4Ghz LoRa. Range is shorter but still longer than 868mhz. If you search 2.4Ghz LoRa on our Youtube channel you'll find some interesting content on that.
