ZTE is pleased to support CSL Mobile Limited in the commercial launch of VoLTE (voice over LTE) services in Hong Kong, delivering consumers a superior user experience in voice and video calls.

CSL users are able to access VoLTE services with any compatible devices. Almost 100,000 users are using the VoLTE service since it was launched by CSL in late August.

ZTE’s VoLTE solution, an end-to-end 4G LTE technology, uses high-speed data packet switching in real time to achieve a large reduction in call connection times. Based on test results, the connection time for a call between two VoLTE users is approximately one second, while a call from a VoLTE user to a non-4G user can be connected in four seconds, compared to seven seconds for 3G calls. Not only is voice quality improved, but video calling resolution can now reach 640x480pixels and voice and video calls can be switched seamlessly.

Mr. Liu Jianhua, head of ZTE’s core network product lines said, “As 4G services develop, the key arbiter of network quality is user experience. With ZTE’s rich experience in helping operators deploy LTE deployments around the world, we are committed to providing the latest and greatest 4G voice services to Hong Kong.”

As one of the world’s leading end-to-end IP Multimedia Subsystem network providers, ZTE’s solutions are deployed in 160 commercial and trial networks globally, including China, Germany, Austria, Italy, Poland, Turkey, Slovenia, Namibia, Peru and the United States.
