Samsung's 3GPP-Compliant PS-LTE Network

After having been discussed for years by others, Samsung finally announced back in April that they are powering the world’s first 3GPP-compliant nationwide public safety LTE (PS-LTE) network in Korea, in collaboration with leading mobile operators.

A press release from them said:

This PS-LTE network, operating in the 700MHz spectrum, offers fast and reliable connectivity to first responders in over 330 public safety organizations and agencies, including police, firefighters, emergency medical services and the military.

The deployment includes Samsung’s Mission-Critical Push-to-Talk (MCPTT) with multimedia broadcast capabilities, known as evolved Multimedia Broadcast Multicast Service (eMBMS). This enables simultaneous transmission to up to 2,500 user devices per cell, which is more than twice the volume of devices supported by previous generation technologies.

In this buildout, the PS-LTE network was also interconnected with the existing LTE-Maritime (LTE-M) and LTE-Railway (LTE-R) networks that were already operating in the 700MHz spectrum.

With nationwide coverage, the network serves as a unified platform that helps ensure interoperability among various public safety institutions. This delivers real-time accessibility and enhanced communications capabilities among public safety agencies and personnel in emergency situations.

They also released an Infographic and a Whitepaper.

In a recent Networks Techtalk, Timothy Paul discussed Samsung’s latest end-to-end MCPTX solutions that provide powerful data and video communications capabilities designed for first responders and public safety officials. The video of that is embedded below:
