China Telecom has selected Spirent Communications as exclusive provider of VoLTE audio test systems. Spirent’s Umetrix audio product is being used to measure the performance of every new smartphone design, and China Telecom has set quality requirements to be met.
China Telecom tests how smartphones carry voice, and how successful they are at establishing and maintaining calls. These tests are performed while simulating realistic network conditions, such as when handsets are moving between cells, when they are in low signal areas, when networks are congested, and while the handset is simultaneously sending and receiving data.
Spirent’s Umetrix technology is designed to take key performance indicators (KPI) measurements in a completely automated lab test environment, and in live network field tests to stress handset designs and point out areas for improvement.
