It’s all about performance

Readying wireless devices for network deployment is an increasingly diverse and difficult challenge. In addition to voice and video quality, you need to thoroughly test areas like signaling, data throughput and mobility. Spirent’s industry-leading radio access test systems cover these critical test areas for all wireless devices.

Leading the industry in audio quality testing

The new Enhanced Voice Services (EVS) codec is delivering higher audio quality to wireless devices and Spirent is working closely with leading chipset manufacturers to expedite the rollout. The EVS codec allows service providers to optimize network resources and call quality at the same time; however, devices need to be tested comprehensively due to the extent and robustness of the EVS feature set. Read Spirent’s white paper to learn more about the EVS codec and the testing necessary to address the specific challenges associated with EVS-enabled devices.
