Ericsson and Sony demonstrated HD quality voice and video calling (VoLTE) using TD-LTE (VoLTE).
The demonstration, which was conducted at Ericsson’s Wireless Innovation Lab & Demo Center (WILD Center) in Shanghai, featured Sony’s 4G phone Xperia SP M35t smartphone, which supports TDD/FDD LTE, TD-SCDMA, HSPA and GSM over 13 bands.
A connection to the Core & IMS nodes located in Ericsson’s VoLTE Competence Center in Anyang, South Korea was used for the HD voice and video calling over LTE demonstrations, using Ericsson’s end-to-end core and radio network infrastructure.
Sony’s Xperia SP M35t will be commercially launched when 4G licenses are released in China.
- In February, Ericsson successfully supported China Mobile in demonstrating the world’s first dual-mode HD VoLTE call between TD-LTE and LTE FDD at the Mobile World Congress in Barcelona.
