Summary: | Methods and devices for synchronizing a device clock in a wireless network (e.g. a LPWAN) are disclosed. Example methods comprise identifying a device temperature, identifying a clock drift associated with the identified device temperature and applying a correction to the device clock based on the identified drift. For the identified device temperature, the drift is identified by comparing the confidence of the drift value in a pre-calibration curve generated from fixed drift values in a pre-calibration table with the confidence of the drift value in a learning curve generated from variable drift values in a learning table and selecting the drift value from the curve having the higher drift confidence. |
