‘Mission Critical Push to Talk solution’
SK Telecom has developed the next-generation wireless communication technology that allows hundreds of rescue workers to communicate well with one another even in large disasters.
The company announced on January 22 that it jointly developed the Voice over LTE (VoLTE)-based mobile communication technology “Mission Critical Push to Talk (MCPTT) solution” with Nokia, a global provider of network infrastructure and related services, for the first time in the world and succeeded in demonstrating the new technology at the Nokia Research Center in Krakow, Poland, on the 19th (local time).
VoLTE is a technology that realizes high quality voice calls over a fourth-generation (4G) Long Term Evolution (LTE) network. The VoLTE-based MCPTT solution enables hundreds of rescuers to make and receive voice calls clearly and communicate each other stably in disaster sites.
SK Telecom is planning to use the new technology in the nation’s Public Safety-LTE (PS-LTE) network and LTE-R, which is the LTE mobile telecommunication technology for railway, network systems. In addition, the company will seek ways to tap into the market of countries which are currently pushing forward projects to establish disaster safety networks, such as the United States and Britain.
