Several MVNOs are possible contenders for the wireless bandwidth other than 3 mobile operators, which are all announcing competition for the 20 ㎒ bandwidth of the 2.1㎓ range. 3 operators, KT, SKT and LG U+, are also wanted in that frequency band as they could be used to provide 3G services as well as Long Term Evolution technology. 1.8㎓ band is also expected to be up for auction together with 2.1㎓ band. KCC is also discussing what procedures should be followed if new operators turn up to take home the frequency license, according to a KCC official.
