Meanwhile, Jung said SKT would launch 21-Mbps HSPA+ services in Seoul this month and boost spectrum efficiency to stabilize data traffic via a six-sector solution that doubles the number of sectors per base station.
The six-sector strategy is also what will allow SKT to offer all-you-can-eat data plans at a time when other cellcos are moving away from them due in part to capacity constraints, said Jung.
SKT says that a mere 1% of its data users are generating 54% of its data traffic thanks to the growing popularity of smartphones like the Samsung Galaxy S.
SKT will also launch commercial LTE services in Seoul next year, with plans to expand the service nationwide by 2013. SKT will launch LTE data modems in 2011 and dual-mode HSPA/LTE devices by 2012.
SKT also accelerated its Wi-Fi hot-spot strategy, saying it will create 15,000 “T Wi-Fi Zones” nationwide by the end of 2010 – about 50% more than initially planned at the beginning of this year.
