Sigma-ML is a compact, lightweight wireless network measurement application that operates on a smartphone. Dedicated large hardware or computer is not required for data collection. Sigma-ML can discover the problem of wireless network in essential field testing in order to analyze the cause, and can perform and measure by using wireless monitor using smartphone. It greatly improves the work efficiency.
All Measurements are Automatic
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, and 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.
Acquisition of Detailed Data
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 analyze in details the wireless data on the device side and it is possible to discover the root cause of the problem.
VoLTE
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 analyze the quality of voice calls from a variety of angles, and the root cause of the problem can be easily deducted.
