Abstract:
Evaluation of network performance is very important because it changes and developments continue to occur in the world of telecommunications, especially in mobile telecommunications. To continue improving the best performance of a system it is necessary to evaluate in the system through the performance evaluation of cellular networks based on the problem in the network one of which is signal disturb such as interference. Research by the author is to overcame the interference that occur in Purbalingga area base on network performance with the optimization (retune frequency) on Site has interference. Results of research conducted that condition Site Padamara and Selabaya has adjacent interference, so that to solve that with retune frequency on Padamara Site. Condition RxLevel ≥ 95 dBm before retune BCCH is 96,81% and after retune BCCH is increase became 99,28%, condition RxQual ≤ 5 before retune BCCH is 46,30% and after retune BCCH is increase became 67,04%, and condition SQI ≥18 before retune BCCH is 69,49% and after retune BCCH is increase became 73,95%, condition C/I before retune BCCH has percentage 43,31% and after retune BCCH is increase became 54,47%. Also that performance SDSR before retune BCCH is 95,77% and after retune BCCH is increase became 97,078%, performance HOSR before retune BCCH 94,29% and after retune BCCH is increase became 97,078% and performance TDR before retune BCCH is 1,68% and after retune BCCH is increase became 1,43%.Keyword: performance, optimization, adjacent channel interference, BCCH,retune frequency
