RF OPTIMISATION OF GSM NETWORKS USING ANTENNA PARAMETERS

Key performance indicators (KPI) are used by the GSM network operators to evaluate their network performance as well as the quality of service(Qos). Drive test results are used to optimise the GSM network. Network optimization process and network optimization using antenna parameter setting is carried out then the results are justified, eventually the value of incorrect antenna parameter setting on network optimization is dis-played. Important KPIs such as Call Drop Rate (CDR), Call set up success rate (CSSR), Handover Success Rate (HSR) and Traffic channel (TCH) congestion rate the quality of service (QOS) are used for the performance evaluation of GSM network RF optimization.
