What is LoRaWAN?
LoRaWAN is a Low Power Wide Area Networking (LPWAN) communication protocol that utilises wireless RF technology (LoRa). LoRaWAN is designed for use with long range, small sized payloads.
As defined by the LoRa Alliance, the LoRAWAN specification is designed to wirelessly connect battery operated ‘things’ to the internet in regional, national or global networks.
It is a popular specification for Internet of Things (IoT) devices due to its versatility and security.
How is LoRaWAN used in IoT?
Using LoRaWAN, you can connect battery operated ‘things’ to a network to collect valuable data. Due to it being a LPWA network protocol, these devices can be in places other protocols do not accommodate for.
Devices can be in a range of convenient places to collect data, such as up a light pole, in a paddock or on a car. The end-node devices “talk” to each other through gateways which relay the transmitted data onto a centralised network server. This data can be sent to an easy-to-read dashboard where valuable insights can be observed.
What are the benefits of LoRaWAN?
-
Scalable
LoRaWAN IoT networks are easily expandable, use bi-directional communication and as a wide-area network protocol, allows expansive coverage. Devices can be easily added to a network without disruption to existing architecture.
-
Reliable
The underlying architecture of LoRaWAN is simple compared to cellular, another more complex option for IoT networks. Due to lower complexity, faults are easier to diagnose and resolve since network diagnostic tools are at your fingertips.
-
Secure
LoRaWAN utilises end-to-end security and uses two layers of cryptography to ensure a secure network.
-
Flexible
LoRaWAN IoT networks can be uniquely designed to meet the requirements of each client. Available resources can be optimised to suit each customer, use case and geographic situation. Unlike cellular networks, you have the power to decide where your gateways are positioned.
-
Free-to-use on The Things Network (TTN)
LoRaWAN is free to use through services like The Things Network (TTN). The TTN IoT community welcomes and openly encourages collaboration and sharing the network for the benefit of furthering research and greater accessibility.
