No, not long air-time but short messages… Before starting this discussion I guess you need to read about what LoRaWAN can do, and [about its message limitations](https://www.thethingsnetwork.org/forum/t/limitations-data-rate-packet-size-30-seconds-uplink-and-10-messages-downlink-per-day-fair-access-policy/1300), and determine if LoRa(WAN) is suitable for your use case.
