Utilizing long-range communications
Beyond PANs and Local Area Networks (LANs), there are situations that require microcontrollers to communicate over longer distances. Sometimes these devices are fixed, while at other times they are in motion. The following technologies cater to these scenarios.
LoRaWAN is based on the promise of two things: low power and long range. It is not designed for transmitting at broadband speeds, but the small packets of data that it transmits can reach great distances without requiring the devices to consume a lot of power. LoRaWAN networks utilize a point-to-multipoint topology. LoRaWAN gateways are connected to power and the internet, and they relay messages from endpoint clients. LoRaWAN devices can communicate at distances reaching 16 km in open fields, and 5 km in densely populated areas.
LoRaWAN gateways come in both indoor and outdoor variants, and you can easily set one up yourself. Additionally, you can configure your gateways...
