[. . . ] TEMSTM VISUALIZATION ENTERPRISE BRIDGING THE OPTIMIZATION GAP 2 TEMSTM VISUALIZATION 7. 2 ENTERPRISE SEE YOUR NETWORK IN A WHOLE NEW WAY TEMS Visualization has revolutionized the optimization of WCDMA and GSM networks. It post-processes event-based data generated by the Ericsson infrastructure, analyzing and organizing it for troubleshooting, monitoring, and verifying network functionality. Lookingatindividualcalldatafromtheinfrastructuresidebridgesthe gapbetweenperformancemanagementsystemsanddrivetesting. While performance management tools provide masses of data, and drive-test toolscapturethinslicesofnetworktraffic, TEMSVisualizationderivesdetailedinformationfromlargevolumesofdata.
