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.
