Automatic clock calibration of a remote unit using phase drift |
摘要 |
An automatic calibration of a clock of a wireless portable part with respect to a clock of a fixed part in a field environment. The calibration performed in the field environment negates the need to calibrate the clock during manufacture and negates the need for an initial field recalibration because of temperature differences between manufacture and the field. In performing the calibration the frequency of the clock of the portable part is varied until the portable part is synchronous with the fixed part to with in a range of timing bits. The portable part is declared calibrated after remaining calibrated for a defined number of data frames. |
