Anritsu broadens support for LTE development with release of software for testing circuit-switched voice functionality in LTE devices

The MX882012C-016 LTE FDD CS Fallback to W-CDMA/GSM software package offers an all-in-one, cost-effective solution for evaluating the CS Fallback function of multimode LTE terminals.
Since LTE is IP-based, voice services are in time expected to use IP-based Voice-over-LTE*. But because it will take time to convert today’s mobile communications infrastructure to IP, many network operators will in the short term provide voice services for LTE handsets over legacy, circuit-switched W-CDMA or GSM networks.

CS Fallback technology makes it possible for an LTE terminal to provide voice services on W-CDMA/GSM networks.This means that handset and terminal manufacturers require a means to test the operation of the CS Fallback function in terminals that they design and manufacture. Anritsu’s new MX882012C-016 package provides this capability, both for R&D engineers developing terminal prototypes, and production engineers managing volume manufacturing of end products.

For volume production test rigs, Anritsu’s patented Parallelphone® measurement technology running on the MT8820C supports the simultaneous testing of two mobile phones. Using the new MX882012C-016 software, manufacturers can achieve very high throughput on LTE production lines of terminals with CS Fallback capability.
