At Mobile World Congress, NVIDIA is touting its Icera 410 LTE modem chip in VoLTE and SRVCC HD voice applications.
Like Ericsson and Qualcomm, NVIDIA will be demonstrating seamless handoff of calls between an LTE network to a circuit-switched WCDMA 3G network – and vice versa – using Single Radio Voice Call Continuity (SRVCC) using AMR-WB. What this means is if you’re making a VoLTE call (AMR-WB/HD voice call) and move back to 3G land, the call should be transparently and seamlessly moved between networks using a single radio. One radio, fewer parts, smaller phones, lower power/better battery life.
NVIDIA says the Icera modem – acquired with the purchase of the UK company last year – is “currently used more” than any other modem to validate LTE handover test cases.
