GENEX Probe Is a drive-test system targeted for network performance.

It is significant for troubleshooting, verification, optimization, and maintenance of

UMTS and GSM networks.

GENEX Assistant Is a post-processing system that incorporates

analysis of drive test data and RNC data. Now it can analyze drive test data

of UMTS and RNC data at one time.

GENEX U-Net Is a network planning system for GSM, UMTS and

CDMA2000. It supports network dimensioning, coverage prediction, system

simulation, propagation model calibration, radio data tuning and auto site

selection.

GENEX Nastar Is a network performance analysis platform,

supports 2G and 3G networks. By analyzing configuration and performance

data, such as CDR data, RTWP data and RSSI data, it can develop a good

solution to network problems.
