Samsung helps launch world’s first 3GPP-compliant nationwide public safety network Samsung has announced that its MCPTX (Mission-Critical Push-to-Talk) technology is powering the world’s first 3GPP-compliant nationwide public safety network that has been deployed in South Korea. The company collaborated with the leading mobile network operators in the country for the launch of the network. The network is based on LTE and operates on the 700MHz spectrum. It offers fast and reliable network connectivity to first responders, including emergency medical services, firefighters, military, and police. Thanks to Samsung Network’s eMBMS (evolved Multimedia Broadcast Multicast Service) technology integrated into MCPTX, the PS-LTE network is also capable of multimedia services like sending messages, videos, and video calling. Samsung claims that the PS-LTE network can service up to 2,500 devices per cell, double than what was possible in previous-generation public safety networks.
