Abstract

Currently each telecom operators are still aggressively increased its 3G/UMTS base stations in Surabaya, which aims to increase the traffic channel capacity and expand coverage. On the other hand, the addition of 3G/UMTS base stations have a positive impact on improving traffic channel capacity and wide coverage, but on the other hand the addition of 3G/UMTS base stations demanding needs of an increasingly frequency decreases. The use of frequencies that are too much without being followed by the frequency setting is good, it will lead to an indirect interference that can degrade the quality of the signal. These directly affect the customer perceived signal quality. In this thesis, we will discuss 3G/UMTS RF signal quality that is felt by every customer service by using the method of test drives. Where the drive test can be known information RSCP (Receive Signal Code Power), Ec / No (Energy Per Carrier Noise), the distance of BTS and MS, interference and handover process. From information on the results of these test drives, we can know the network performance of each operator 3G/UMTS, so can we conclude whether the state of the state radio a 3G/UMTS base stations is feasible or necessary to do a repair. Based on measurements in the area of Central Surabaya, East, North, South, and West with the normal method (can capture the signals of GSM and 3G/UMTS) and the method lock (only to receive signals 3G/UMTS). The percentage of best RSCP value (-85 dBm to 0 dBm) of the highest Telkomsel by 80.2% when using the normal method and the operator Telkomsel is the highest of 52.6% when using the lock method, precentage value Ec/No answer (-6 dB to 0 dB) of the operator Telkomsel highest at 71.6% when using the normal method and the operator Excelcomindo highest at 47% when using the lock method, precentage next best SQI values (18 to 30) of the operator Excelcomindo for 71.6% when using the normal method of operator Excelcomindo and also when using the lock method of 64.6%. Keywords: QOS, RSCP, Ec / No, SQI, 3G/UMTS
