While Verizon, AT&T, and MetroPCS are all in the process of deploying 4G LTE networks for data, they are still using their 3G technologies to handle voice calls. Qualcomm has now successfully completed test calls over LTE using their MSM8960 Snapdragon S4 chipset, meaning a future of an all-LTE network that can handle both voice and data is one step closer! Below is Qualcomm's press release:
SAN DIEGO – February 02, 2012 – Qualcomm Incorporated (NASDAQ: QCOM) today announced that the Company, working with Ericsson, has successfully completed the first voice call handover from an LTE mobile network to a WCDMA network using Single Radio Voice Call Continuity (SRVCC). An important technology required for voice-over-LTE (VoLTE) support, SRVCC is a 3GPP specified feature that enables continuity of service by seamlessly switching to a WCDMA network when a consumer on a VoLTE call leaves the LTE network's coverage area. This milestone occurred on December 23, 2011 with an Ericsson network using a handset which incorporated Qualcomm's Snapdragon™ S4 MSM8960 3G/LTE multimode processor. A demonstration will be available at Qualcomm's booth at Mobile World Congress in Barcelona, Spain February 27 – March 1, 2012.
