Spirent accelerates TDD-LTE testing in mobile devices

Spirent Communications announced TDD-LTE support on the Spirent CS8 Mobile Device Tester. Spirent CS8, a tool for device R&D testing, is now able to perform data throughput, voice quality, location based services and mobility testing for chipsets and mobile devices that support TDD-LTE.

The CS8 Mobile Device Tester is now capable of testing in the key frequency bands for TDD-LTE deployment, in addition to the common FDD-LTE bands. Spirent's CS8 provides the ability to emulate MIMO-enabled cells for both TDD-LTE and FDD-LTE networks simultaneously within a single instrument.

The CS8's ease of use enables device development teams to quickly configure TDD-LTE and FDD-LTE cells, creating and executing custom test cases that help get their devices to market faster.

"Extensive R&D testing of both TDD and FDD in LTE devices is critical to the successful deployment of LTE in many major markets, and seamless interoperability between these technologies is essential" said Brock Butler, mobile device testing architect, at Spirent Communications.

Butler further added, "Subscriber expectations for quality of voice service, data, mobility and usability of feature-rich LTE-enabled smartphones are driving our industry to new levels of performance testing. Spirent helps R&D engineers with these test challenges by providing the only solution in the industry that integrates the leading live network service experience measurement tools for voice quality and data performance."

Spirent has integrated its DatumLab solution with the CS8 for data performance measurement of TDD and FDD-LTE devices. Spirent DatumLab is a lab-based evolution of Datum, one of the most widely used measurement tools for quantifying device performance in the live network.

The CS8 now enables support for TDD-LTE A-GPS Over-The-Air (OTA) testing. A-GPS OTA testing is the only methodology that includes the effects of the antenna to provide a complete validation of GPS performance in mobile devices.
