Tata Communications will shortly bring solutions that help telecom operators offer voice calls over fourth-generation network, which transfers data at high speed but isn't considered a quality carrier of voice.
Since most of the revenue for telecom operates comes from voice services, voice calls over 4G long-term evolution network - also called Voice over LTE or VoLTE - is expected to become a key factor for the success of 4G. It allows mobile operators offer high-definition voice over 4G LTE networks.
"Voice still is a killer app for service providers. Consumers may pay twice, if they experience the quality of HD voice on VoLTE," John Hayduk, president of product management and service development at the operator of undersea cables and Internet solutions, told ET recently.
