Backend Setup
The figure below shows the major components in a LoRaWAN system.
Fig 23. LoRa WAN Environment
In the LoRa WAN ecosystem, sensor readings take the following path:
the LoRaWAN Node reads the sensors and builds the values in to
a data packet
the Node then transmits the values over its LoRaWAN radio
module
the transmission from the Node is processed by a LoRaWAN
Gateway
◦
in the LoRa WAN system, Gateways are relatively primitive
devices: after receiving a packet of data, they simply forward it
on (the program running on the Gateway is thus referred to as
a Packet Forwarder)
◦
as LoRaWAN is intended as a wide area network, it is possible
that two or more Gateways may be in range of the Node
◦
each Gateway processes the packets of data and passes them
on to a LoRa WAN Server
