From October 11-13, 2016, Vital Alert Communication attended the 2016 Frontier Nonferrous Mining and Intelligence Information Technology Conference in Changsha city, China. Our partners in China introduced our TTE technology and tunneling capabilities to the Changsha subway system. With 2 subway lines, 44 stations-some of which go under the Xiang Jiang river, our TTE capabilities are an asset to public safety and underground communications.
