Mobile in Korea

   Korea Communication Commision requested in-depth research about voice service on WiBro to Korea Information Society Development Institute. WiBro was commercialized by KT and SKT in 2006, but WiBro was permitted for only data service, not voice service. Because voice service can not be provided on WiBro, call number for each WiBro device is not necessary until now.

   However, because KISDI started to investigate the long-term effects to the telecom industry of Korea if voice service is allowed on WiBro, new competition might be started on mobile industry of Korea. Real mobile services, including voice and data services, are only provided by mobile operators such as SK Telecom, KTF and LG Telecom. If voice service on WiBro is possible, KT can participate in the competition. KT has steadily insisted that voice service on WiBro be provided.
 
   If Korean Government permits the voice service on WiBro, will KT and SK Telecom start the service? I think it is not sure. There are two reasons.

   First, COVERAGE of WiBro!! Even if KT and SK Telecom commercialized WiBro service in 2006, the services only cover Seoul and near areas of Seoul. In addition, WiBro is well operated outdoor only. Indoor, the signal of WiBro is very weak. KT and SK Telecom should invest much money to strengthen the network coverage. Because the penetration rate of mobile voice service in Korea is already over 90 percent, it is not sure whether the operators make the huge investment on WiBro.

   Second, the merge of KT and KTF is expected within near future. Even if KT promotes WiBro service aggressively and wants voice service on WiBro in order to strengthen WiBro service now, KT might lose the driving force for voice service on WiBro after merging KTF. KT can provide mobile voice service through KTF without voice service on WiBro.

   I am wondering how KISDI will make the final decision about the voice service on WiBro. I will make a posting after announcement of the decision.
