Lora

lora

• limitations https://www.thethingsnetwork.org/docs/lorawan/limitations.html
  • fair use

    8 frequencies
    5% receive duty cycle on the gateway
    86,400 seconds in a day
    1,000 nodes

Golden rule: 30 seconds air-time per device per day
For 10 bytes of payload, this translates in (approx.):

    20 messages per day at SF12
    500 messages per day at SF7
    more for SF7BW250 and FSK (local-area)

If your application requires more bandwidth, think of another solution This allows for >1000 nodes per gateway Downlink bandwidth is even more restricted

   you can’t send all messages as ‘confirmed uplink’
