(Telecompaper) South Korea plans to invest KRW 1.6 trillion (approx. USD 1.5 billion) through 2020 to build a 5G mobile network. The Ministry of Science, ICT and Future Planning has been in talks with the country's three mobile operators as well as technology firms such as Samsung and LG to draw up a plan, Yonhap News Agency writes. The ministry is hoping to strengthen ties with US, Chinese, and European telecom authorities to establish standards for 5G and avoid excessive patent battles. The first test run for the 5G network on social networking sites is planned for 2015.
