1. A method of determining a location of a mobile device communicating with a long-range low-power wide-area network (LoRaWAN), the method comprising:
collecting, while the mobile device is moving within a reception area of the long-range low-power wide-area network (LoRaWAN), signals transmitted between the mobile device and one or more gateways of the long-range low-power wide-area network (LoRaWAN) that have known locations; and
evaluating the signals, using a model that is configured to accept input values relating to a signal strength measure (RSS) of electromagnetic signals, wherein the evaluating comprises:
deriving for each signal of the signals, values representative of signal strength measure of the signal; and
applying the values as input signals into the model;
generating using the model, adjustment values based on an attention measure, a self-attention, and/or other input signals representative of locations; and
adjusting using the model, the values representative of location of the mobile device based on the adjustment values.
