VoLTE intercom series
VoLTE (Voice over Long-Term Evolution or Voice over LTE, generally referred to as high-definition voice, also translated as long-term evolution voice bearer) is a high-speed wireless communication standard for mobile phones and data terminals.
It is based on the IP Multimedia Subsystem (IMS) network, which uses a specially designed profile for the Control plane and the media plane of the voice service (defined by the GSM Association in PRD IR.92) on LTE. This allows the voice service (control and media layer) to be transmitted as a data stream in the LTE data bearer network without the need to maintain and rely on traditional circuit switched voice networks.
VoLTE's voice and data capacity is more than three times that of 3G UMTS and more than six times that of 2G GSM. Because VoLTE packet headers are smaller than unoptimized VoIP/LTE, they also make more efficient use of bandwidth.4G intercom system enables VoLTE conditions. 1.Mobile phone must support VoLTE. 2.SIM card supports VoLTE and needs to be with the telecom provider. 3.intercom system module has support carrier
