General presentation
The WebdynEasy LoRaWAN hub is part of a line of Webdyn hubs specific to wireless networks.
The hub’s main function is to be a LoRaWAN gateway to create a LoRaWAN network and
collect the data from the different LoRa sensors deployed nearby. The LoRaWAN gateway has
2 running modes:
•
Packet Forwarder
•
Packet Forwarder with embedded LoRaWAN server
The hub is also used to communicate with Modbus devices in IP or RTU mode.

The LoRaWAN protocol
LoRaWAN is a communication protocol that uses LoRa modulation. This communication
protocol uses several radio bands (ISM) that are available in the 868 MHz range in Europe
without a licence.
In a LoRaWAN network, the radio modules are not paired to a single base station. The data
they send is relayed by multiple base stations. Each one sends the information received from
a radio module to the management server via a gateway. The intelligence and complexity are
