ZTE Powers CSL’s VoLTE Service in Hong Kong
ZTE has announced that company's VoLTE Solution is supporting CSL's commercial launch of voice over LTE services in Hong Kong for voice and video calls. Almost 100,000 users are using the VoLTE service since it was launched by CSL in late August.
According to ZTE, its VoLTE solution uses high-speed data packet switching in real time to achieve large reduction in call connection times. Based on test results, the connection time for a call between two VoLTE users is typically about one second, while a call from a VoLTE user to a non-4G user can be connected in four seconds.
In addition, video call resolution can now reach 640x480pixels and voice and video calls can be switched with just one key, company added.
