GENEX ProbeIs a driv e-test systemtargeted for network performance.
It is significant for troubleshooting, verification, optimization, and maintenance ofUMTS and GSM networks.
GENEX AssistantIs a post-processing systemthat 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-NetIs a network p lann ing s ystemfor GSM, UMTS and
CDMA2000. It supports network dimensioning, coverage prediction, system
simulation, propagation model calibration, radio data tuning and auto site
selection.
GENEX NastarIs a network performance analysis plat form,
supports 2G and 3G networks. By analyzing configuration and performance
data, such as CDR data, RFMT data and RSSI data, it can develop a good
solution to network problems.

The U-Net is currently being used by several operator and design
institutes for network planning.
All Huawei commercial and trail networks are planned with U-Net.
The U-NET planning software is widely applicated in more than 20
networks, dozens of WCDMA commercial/trail network overseas.
U-Net software scores favorable evaluation in the evaluation test of
9 planning software such as Aircom, Ericsson, Maconiand so on,
conducted by China Mobile Design Institute.
