ANALISIS KUALITAS PANGGILAN PADA JARINGAN GSM MENGGUNAKAN TEMS INVESTIGATION

Abstract

Drivetest is a way to get information that performed online from TEMS devices. For drivetest and logfile recording, devices have to be connected. Instead presents online data, TEMS replays logfiles for advanced observations and analysis. In this Final Project, TEMS Investigation is used outdoor and uses GPS (Global Positioning System) as navigation device and parameters plotting through drivetest route. Parameters that observed is RxLev, RxQual, andn SQI. Drivetest done every Saturday and Sunday during three weeks, starting on August 23rd 2009 until September 10th 2009 in drivetest area that divided in four sub routes. By means of datas collecting by drivetest during three weeks, call quality in GSM network can be found out, such as dropped call, blocked call, and another events occur. Those events can be observed from RxLev, RxQual, and SQI values that performed on screen during call. Drivetest results show that the best call quality are on average value of RxLev, RxQual andSQI, respectively -79.33 dBm, 0.67; and 24.78, while the worst call quality are on average value of RxLev, RxQual andSQI, respectively - 78.00dBm, 1.78, and 17.44. As for the best service quality provided by operator at CSSR and DCR value, respectively 94.73% and DCR 0%, while the worst value of CSSR and DCR, respectively 64.86% and 0%.
