The Chosun Ilbo reports that Seoul's Subway Line Number 2 has become one of the city's major WiFi hotspots. The reason? It passes by major universities including Ewha Womans, Hongik, Seoul National and Yonsei Universities and is now notable for passengers' lively use of smartphones. According to statistics released by KT, Line 2 recorded 2.56 times more WiFi data consumption than the average of 14 subway lines running through Seoul and adjacent areas. KT also noted that 94 percent of WiFi data usage was accounted for by smart phones."The soaring WiFi traffic on the Line No. 2 stations including Dongdaemun, Gangnam, Hongik University and Samseong shows that most smartphone users are young people in their 20s or 30s," KT said.
