Abstract
A system and method of predicting a life time of a device and determining a life time left for the device, includes a temperature sensor, disposed proximate to the device, sensing temperatures of the device at a plurality of time intervals; a memory, coupled to the sensor, recording the sensed temperatures from the sensor; and a controller, coupled to the memory, determining life time points of the device corresponding to the temperatures, calculating accumulated life time points of the device on account for the time intervals to predict the life time of the device. In operation, given a measured temperature, a life time left for the device is determined. Accordingly, the device can be replaced by a new device before it fails, thereby improving reliability of a system, such as a communication system at BTS (Base Transceiver Station).
