Qualcomm Claims First VoLTE-to-WCDMA Call Hand-Off
Qualcomm today announced that it and partner Ericsson have successfully completed the first voice call handover from an LTE mobile network (using voice over LTE — or VoLTE) to a WCDMA network. The call used Single Radio Voice Call Continuity (SRVCC), which is required for VoLTE calls to seamlessly switch to a WCDMA network when a consumer on a VoLTE call leaves the LTE network's coverage area. SRVCC and its predecessor CSFB (circuit-switched fall back) allow both LTE and 3G network connections to be supported on a single chip, which lets handset makers design smaller, less expensive, more power-efficient phones. The test was completed using an Ericsson handset with Qualcomm's Snapdragon S4 MSM8960 3G/LTE multimode processor.

Qualcomm and T-Mobile have successfully completed the first data call using Qualcomm's X55 modem, the first 5G chip for phones to support all 5G networks to be launched in the US in 2019, including T-Mobile's band 71 (600 MHz). All 5G phones currently on the market in the US use the X50 chip, which only supports mmWave bands and TDD bands such as Sprint's band 41.
