Geolocation is the ability to determine the location of a LoRa sensor without using GPS. This is an add-on and does not have to be available on every LoRaWAN network. The LoRa sensor does not need to implement additional functionalities for this. The location of a sensor can already be determined when an uplink message is received by three or more LoRaWAN gateways.
Geolocation how does it work?
The LoRaWAN network is able to determine the position of a sensor by analyzing the times when an uplink message is received on the different gateways. A location can be derived by calculating the difference in reception times of the different gateways. To do this, special gateways are needed that support the geolocation functionality.
