Like for the European 863-870MHz band, the maximum application packet size varies: The data rate DR (defined by spreading factor SF and bandwidth BW) and maximum packet size roughly depend on the distance to the nearest gateway, and are also defined in the specification for each region. The following regulations apply as well: LoRaWAN data rate, spreading factor, and application packet sizes An online airtime calculator can give you some insight. At most 10 downlink messages per 24 hours, including the ACKs for confirmed uplinks.Ī good goal is to keep the application payload under 12 bytes, and the interval between messages at least several minutes.An average of 30 seconds uplink time on air, per 24 hours, per device.For The Things Network’s public community network the Fair Access Policy limits the data each end-device can send, by allowing:
