Solution Features
4G GSM intercom system is easy entering and exiting - simply dial a number and the gate opens. Locking the system, adding, deleting and suspending users is done easily using any phone. Mobile phone technology is much more secure and easy to manage and at the same time eliminates the need to use multiple, special-purposed remote controls and key cards. And since all the incoming calls are not answered by the GSM unit, there is no call charge to the users. Intercom system supports VoLTE, enjoys clearer call quality and faster phone connection.
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.
