EVALUATION OF RELIABILITY INDICATORS OF MOBILE COMMUNICATION SYSTEM BASES

In this study, the reliability of mobile system base stations (BTS) is assessed by analyzing data obtained on faults in about 200 BTS over a six-month period. Five BTSs with the highest number of failures and duration of failure were selected in these BTSs. Based on the data obtained, reliability parameters were calculated and compared. The study used Weibull’s dismissal process distribution method. The breakdown times of each BTS were sorted. In all five BTS, it was found that β(where the value of β is the approximate value obtained from the values of the smallest squares of the Weibull graph), thus reducing the failure rate. Defects can be caused by poor quality control, manufacturing defects, poor handling and various malfunctions. Detailed information on the problem was provided and described.
