WTTx Suite Architecture
mAOS
(mobile Agile Operation for Service)
1) Evaluate the coverage, throughput, and capacity
of networks to provide trusted CPE allocation
advice.
2) Identify top N cells, sectors, and sites with low
throughput, high load, weak coverage, and a
small number of CPEs to support in network
performance evaluation.
3) Identify network bottlenecks, and further analyze
WBB and MBB KPIs to support in network
capacity expansion.
4) Evaluate network KPIs for CPEs and their serving
cells to quickly locate network issues related to
CPE.
