Abstract:
1. A system, comprising: a first base station having a first frequency reference unit, a temperature sensor, and a memory having a calibration table stored therein; a second base station having a second frequency reference unit; and a network controller device configured to manage radio resources of the first and second base stations, the network controller device configured to receive frequency information from a subscriber device, the frequency information being based on a first measurement of a first transmit frequency of the first base station and a second measurement of a second transmit frequency of the second base station, wherein the first base station is configured to: receive reference correction feedback from the network controller device, the reference correction feedback being based on the frequency information received from the subscriber device; measure a first operating temperature with the temperature sensor; update the calibration table using data associated with the reference correction feedback and calibration table data associated with the first operating temperature; and correct the first frequency reference unit of the first base station using the updated calibration table.
