Yeah we now support 1.5M devices with our community network and enterprise network. And the most successful ones sent the least amount of data. Here is a list of all the supported devices: https://www.thethingsnetwork.org/device-repository/
Yes, this is an outlier and it took around 8 years for this to be emerge and be detected by the community run TTN mapper initiative. The main fun thing about this is more that it shows how cool it is to have a global community network where we enjoy sending messages for the sake of it just to learn technology. Like kids with 2 cans and a string between them.
So it takes more than 5 dollars. You also need a gateway but you can get these for 99 dollars. Still this technology has a very low barrier to entry for such a long range and low power capability.
Good point. We'll add that to the next post if there is a new record. Also what can be confusing is that the business viable part is even much smaller than the technical viable part. The low power operations is really only at lower SF7 or SF8. And we push our partners and ecosystem to keep the payload as small as possible as every byte counts. It is a completely different way of thinking than WiFi or cellular. Yet I do agree it is presented with the same terms and paradigm and that is confusing.
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.
