All the operations at the time of measurement in Sigma-ML can be automated. All the device operations necessary for field measurements such as the data transmission, download of files, ping transmissions, incoming and outgoing voice calls are performed automatically in the application according to the user setting. Combined with the time and the remote function, unmanned measurements can also be done easily.
Sigma-ML can collect and display not only the application layer data, but also the L1, L2, L3 data of wireless layers from the mobile device and display in real-time. From the quality of the wireless network up to the protocol, Sigma-ML can analyse in details the wireless data on the device side and it is possible to discover the root cause of the problem.
In Sigma-ML, automatic incoming voice calls in correspondence to the VoLTE, recording of voice calls, automatic detection of silence (sound mute), MOS value (POLQA) measurement, RTP/SIP measurement are possible. This can help to improve the quality of voice calls. By saving the wireless packet and, voice quality signals as one data file, it is possible to analyse the quality of voice calls from a variety of angles and the root cause of the problem can be easily deducted.
