What is the impact of repeated transmissions on the capacity of the LoRaWAN Network? Intuitively, it would seem that repeat transmissions just load the network... and this is what will happen with a basic network server. However it is more subtle, because a high-end network server will optimize jointly power, channel diversity (repeat) and datarate. What you ...

Funny how I had never seen that setting, I always though retransmits only occurred for confirmed packets. That's similar to the Sigfox strategy. Note how the wording is different between e.g. 1.0.3 and 1.1.0, though. Multiple shorter transmissions have several advantages: Each transmission occurs on a different channel If there's a downlink, retransmissions ...

Looks like the technology best suited to my requirements is NPR (New Packet Radio) which is a DMR-like TDMA protocol that uses a small RF transceiver module and a TDMA capable amplifier for range and can achieve speeds of around 500kbps usable. https://spectrum.ieee.org/build-a-longdistance-data-network-using-ham-radio

I would suggest using LoRaWAN connectivity, that offers a scalable network infrastructure for several hundred/thousands/millions of devices. For that, you need to deploy the LoRaWAN protocol stack on your stm32 and connect it to a community operated LoRaWAN network like Loriot, Actility ThingPark or TTN. Your selected LoRaWAN network can easiliy be ...

Unfortunately, there are no smartphones with built-in LoRa modem. However, there are several LoRaWAN trackers on the market that can scan for Bluetooth Beacons in the neighborhood, and transmit the result of the scan (a list of beacon IDs) together withe the location coordinates to a central application server via LoRaWAN. These devices can be considered as &...

There's an alternative, but it depends a lot on what the other "LoRa compatible device is". If it has gateway functionalities (ability to listen on multiple channels and data rates and matching software, usually means SX13xx-based) and you can freely program it, then it may be possible to have the LNS directly embedded in the gateway. In that case ...

Should be possible if you have access to the firmware itself! There are many open source projects e.g. with RFM69 moduls from hoperf, which are usefull to create your own propriatary communication between two clients. But as hardllib mentioned, you give less information about the detailed setup and accesabilities you have. If you don't have access to the ...
