Mobile in Korea

I made a post regarding 'Voice Service on WiBro (Mobile WiMAX)' in last August. SK Telecom has maintained a negative stance about voice service on WiBro because voice service on WiBro might cause the cannibalization effect toward SKT's existing voice service on CDMA and WCDMA. However, KT had asked that the government should grant the voice service of WiBro. KT has ever demonstrated the VoIP service using WiBro in OECD Ministerial Meeting of last June. KT seems to solve all technical problems for providing VoIP service using WiBro.

However, KT changed their stance regarding voice service on WiBro. Through 3rd quarter conference call, KT announced that they would not provide voice service using WiBro for quite some time. Why does they change their stance? I think there are two reasons.

First, KT might be concerned about the cannibalization effect as SK Telecom. KT has a plan to become incorporated with KTF, one of their subsidiaries. KTF is a mobile operator and provides CDMA and WCDMA service. If KT provides voice service on WiBro, the service would come into collision with KTF's existing business models.

Also, the coverage and quality of service for voice service might be burdens to KT. The coverage of KT's WiBro service covers only 40% of Korean population. Moreover, KT's WiBro service does not support sufficient quality for voice service in INDOOR SPACE. KT has often communicated with customers by informing that WiBro service could make the best performance in outdoor space. Thus, KT should enlarge the service coverage and improve the quality of service in indoor space as well as outdoor space in order to pursue the voice service on WiBro. It might be not a easy decision.

On the other hand, the Korean government seems to be disappointed that SKT and KT are passive for WiBro business in domestic market. A few days ago, the Government announced that another new WiBro service provider will be selected next year. The Government has additional 27MHz available whithin 2.3 GHz bandwidth. It will be given to a new service provider and both data service and voice service are expected to be permitted on WiBro network. The Korean Government wants to invigorate the WiBro business in domestic market by raising new competition among KT, SKT and a new service provider.

The Korean mobile market is wondering which one will be a new WiBro service provider.
