CSL Mobile launches ZTE’s voice over LTE solution in Hong Kong

CSL Mobile launched commercial VoLTE (voice over LTE) services in Hong Kong, delivering consumers a superior user experience in voice and video calls. The operator is using ZTE’s VoLTE solution.

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.”
