CEM stands, in this instance, not for contract electronics manufacturing but for “customer experience monitoring”, and reveals how much T&M activity extends beyond the bench or the manufacturing/test environment.
Nemo CEM Observer is claimed as an industry first troubleshooting solution which generates CEM data with drive test level network information enabling efficient root cause analysis. Most CEM tools running on a subscriber's mobile device – says Anite – provide both accurate location information and measurement data, no matter when and where the problems occur. However, typical application level CEM data does not address all aspects of QoE. Subscriber perceived data or voice service failures can be caused by network parameters in layer 3 or below. The application could appear to be functioning, yet the end-user is unhappy with the service.
Nemo CEM Observer brings in-depth troubleshooting to Customer Experience Monitoring. It gives engineering-level visibility to mobile network data which can be used to detect the root causes of subscriber experience issues typically caused by the network. Nemo CEM Observer is the first step towards bringing drive test level diagnostics data into the CEM domain, thus enabling the root cause analysis of user experience problems. Coupled with Anite's post-processing tool, Nemo Analyze, the collected data can be efficiently analysed and visualised.
