Optimization Monitoring Troubleshooting

RADIO NETWORK MEASUREMENT TOOL Sigma-LA is a Windows application that captures, monitors and saves RF log data from UEs, scan receivers and GPS devices. Data from 4 UEs , 2 scan-receivers and 1 GPS device can be captured simultaneously. Sigma-LA can also playback saved data after the data collection session has ended. It is an essential tool for optimizing and troubleshooting mobile networks.

5G, LTE/WDMA/GPRS throughput and packet error rate based on L1 data can be displayed on a table or a graph and on a map in real time. L3 message can be decoded in real time and can be displayed with decoded tree structure. Cell site information can be displayed on a map. Sigma-LA provides essential information to optimize radio network.

Sigma-LA is a suitable tool to verify radio network quality through drive test. Sigma-LA can measure network performance simultaneously on four UEs, so that measurement among competitive networks can be done easily. Log file out of Sigma-LA can be imported to Sigma-PA and the data is processed, analyzed and a report is generated automatically.

When a log file is imported and played back in Sigma- LA, call events are displayed on a cell search view. You can easily understand detailed status of network problems by looking at synchronized L3 decode view and a map display. Handover status can be analyzed automatically.
