During the test, Samsung's deployed PS-LTE network was used by 20 departments from eight fields, including the military, government, police, fire, and medical services. All of them responded to simulated emergencies in accordance with Standard Operating Procedure. Various PS-LTE communications were demonstrated, including instant messaging in emergency situations, voice/video Push-To-Talk (PTT) communication, video conferencing between field and command center as well as voice calling by multiple groups. The Korean government selected Samsung as the sole provider of PS-LTE end-to-end solutions. The government is now going to launch the network in four cities starting this month, and coverage will continue to be expanded until the PS-LTE network is available nationwide.
