South Korea’s KT Corp has announced the establishment and demonstration of what it claims is ‘the world’s first trial public safety long term evolution (PS-LTE) network’, the Korea Times reports. With this trial infrastructure said to have been constructed and operated with a view to preparing for the 2018 Winter Olympics, which will take place in PyeongChang, KT has also suggested the rollout will enable it to take a leading role in selling the technology in the global market.
