3. About LoraWan

Here are a few benefits of LoRaWAN connectivity: 

LoRaWAN’s use of the unlicensed spectrum has historically brought down costs.

The decentralized nature of LoRaWAN allows for a great deal of customization, assuming you know how to build a wireless network from scratch.

LoRaWAN has a strong history of success in stationary IoT use cases, like smart buildings and utility meters.
