Samsung Electronics is working with Korean mobile operators on the deployment of the world’s first 3GPP-compliant nationwide public safety LTE (PS-LTE) network. The PS-LTE network will operate in 700 MHz spectrum to provide connectivity to first responders in more than 330 of Korean’s public safety organizations and agencies.
The PS-LTE network is also interconnected with the existing LTE-Maritime (LTE-M) and LTE-Railway (LTE-R) networks, which were already operating at 700 MHz.
Specifically, the deployment includes Samsung’s Mission-Critical Push-to-Talk (MCPTT) with multimedia broadcast capabilities, known as evolved Multimedia Broadcast Multicast Service (eMBMS). According to Samsung, eMBMS enables simultaneous transmission to up to 2,500 user devices per cell, more than twice the volume of devices supported by previous-generation technologies.
