Thanks for your comments. Regarding your doubts on LoRa:
- compared to all other technologies like Zigbee, Enocean, BLE - its is long-range. It allows us to form a long-range local wireless network to assemble sensor data (e.g. industrial site). If we compare to long-range technologies e.g. LoRaWAN doesn’t have any acknowledgment, mostly it is one-direction. We have implemented ACKs, repeats, ping-pong mode which monitors network state
- we use 433 MHz (4x longer distance than 868 MHz, 433 MHz is less used, much less mobile network influence, much better wall penetration, less energy needed to transfer same amount of data as in 868 MHz)
- multi-frequency with 8 non-overlapping channels
- changeable band-width, spread spectrum. You can configure either high-bandwidth/low-range low-bandwidth/high-range
- strong security based on ChaCha20
