  • 20% more extended range (increase in link budget)
  • +22 dBm transmit power
  • A 45% reduction in size: 4mm by 4mm
  • Global continuous frequency coverage: 150-960MHz
  • Simplified user interface with implementation of commands
  • New spreading factor of SF5 to support dense networks
  • Protocol compatible with existing deployed LoRaWAN networks

If I understand correctly, new chipset has LoRaWAN stack integrated?

No I don’t think so … ‘next generation LoRa’… not LoRaWAN
the succesors to the sx1276/78/79 ?

What does “Simplified user interface with implementation of commands” mean then?

There’s something called “protocol engine” on the block diagrams for these chips. No datasheet available yet. We’ll see…
