GENEX Nastar WCDMA Helps You Succeed
Network optimization period is shortened greatly
The
Nastar WCDMA reduces up to 70% time cost
for the routine monitoring of network performance.
Maximizing utilization of network capacity
and investment.
All data is from the system. No need for DT and
CQT. Therefore, more than 60% optimization cost is
reduced.
Maintaining sound network.
Improving network performance.
Enhancing productivity of network
engineers
The Nastar WCDMA converges the experience in
network performance from Huawei technical
experts. The thirdthird-party network optimization is not
necessary; thus saving a large amount of money.
