About LoRaWAN

LoRaWAN is a low-power, secure, wide area (LPWAN) networking protocol designed to

wirelessly connect devices to the internet in regional, national, or global networks. To use the

CS1060 Sensor, wireless connectivity to an internet connected LoRaWAN gateway is required.

For more information about LoRa and LoRaWAN visit the LoRa Alliance webpage:

Terminology

⧫

Message sent from the Sensor to the network are referred to as "uplink messages" or

"uplinks".

⧫

Messages sent to the Sensor from the network are referred to as "downlink messages" or

"downlinks".

Both uplink and downlink messages may be of either "confirmed" or "unconfirmed" type.

⧫

Confirmed messages are guaranteed to be delivered but will consume extra wireless

bandwidth and battery life. These mechanisms are analogous to TCP (confirmed) vs UDP

(unconfirmed) protocols used for IP networks.

⧫

Before a device, such as the CS1060 Sensor can transmit messages using LoRaWAN it

must go through a "join" process. The Join process involves key-exchange with the cloud-

hosted network provider (The Things Network, Helium, etc.) and is defined in the LoRaWAN

protocol standard. If connectivity is lost due to RF interference, power loss or other

temporary internet outages, the device will need to rejoin the network prior to being able to

transmit messages. This process happens automatically but is managed in a battery-

efficient manner and may take significant time.
