Overview#
LoRaWAN defines the communication protocols and system architecture for the Network, while the LoRa Physical Layer enables the long-range Transport Layer.LoRaWAN is also responsible for managing the:
- communication frequencies
- data rate
- power for all devices
Devices in the network use Asynchronous Operation and transmit when they have data available to send. Data transmitted by an end-node device are received by multiple Gateways, which forward the data Packets to a centralized network server.
Data is then forwarded to Application servers. The technology shows high reliability for the moderate load, however, it has some performance issues related to sending acknowledgements
LoRaWAN networks use an ALOHA based protocol, so end devices don’t need to peer with specific gateways. Messages sent from end devices travel through all gateways within range. These messages are received by the Network Server. If the Network Server has received multiple copies of the same message, it keeps a single copy of the message and discards others.
6LoWPAN is a IPv6 implementation.
