Mobile in Korea

   SK Telecom relased WiBro(Mobile WiMAX) Smartphone (SCH-M830) last week. The smartphone is WCDMA & WiBro dual device. WCDMA supports voice & data service and WiBro does data service. Because the coverage of WiBro is limited in Seoul and satelite cities, WCDMA help WiBro to overcome the limitation of coverage.

   Samsung developed this smartphone and Windows mobile 6.1 of Microsoft is adoped as the operating system.

   The below is a videoclip which introduces the smartphone. (The voice in the videoclip and hand are mine. However, because I explained it in Korea, you might not understand what I say.) The videoclip was posted on the official corporate blog of SK Telecom last week.

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.

   SK Telecom announced to develop and commercialize the first WiBro Femtocell. Femtocell is a small sized base station. SK Telecom has already provided WiBro (mobile WiMAX) service in Korea. However, the service has been able to be used at outdoor areas because of limitation of coverage range. SK Telecom announced that the WiBro coverage could be expanded into indoor areas with the Femtocell.

   I think that the price of Femtocell is still expensive (around $300). If the price of Femtocell could go down to around $50, Femtocell would contribute to the expansion of WiBro service. Because the function of Femtocell is very similar to Wi-Fi Access Point's. (Even the external formfactor) Customers are able to buy a Wi-Fi AP with only $50. In sum, I think the Femtocell could be provided with around $50 in order to have a competitiveness.

  I've been to WiMAX Forum Congress Asia 08 from 8th April to 10th April. I am wondering whether mobile broadband based on WiMAX (and LTE) will succeed in developed markets (in terms of mobile service) including Korea, Hong Kong and Japan.

  In the Congress, many participants from emerging markets including India, Malaysia, Indonesia and Pakistan are expecting that WiMAX will perform an important role for roll-out of broadband service. The penetration rates of fixed broadband service in emerging markets are very low under 10%. The providers think the broadband service is a great opportunity for growth and are trying to expand the service through their countries. Because they did not have fixed broadband infrastructure like fiber optic and copper line, they must invest much money in order to provide the broadband service. In this case, mobile or nomadic broadband using WiMAX is more efficient than fixed broadband using fiber optic or copper line. Moreover, some countries including Malaysia and Indonesia consist of many islands. It is very difficult for them to build fixed infrastructures over the whole countries.

  However, developed countries including Korea and Japan have different environments. For example, the penetration rate of broadband service in Korea is over 80%. In addition, there are so many PC cafe providing computer and fast speed internet connection. Usual Korean people might have no needs for mobile broadband. Because the environment of internet connection is well developed, they do not like taking a laptop when they are out of home and do not want to subscribe the mobile broadband service like KT WiBro and SKT T LOGIN. Even if WiBro service was launched in 2006, the number of subscribers is only 150,000 up to now. A pay Wi-Fi service, Netspot, which is a simmilar to mobile broadband service, is not also evaluated as a successful service in Korea. (It has attracted about 400,000 subscribers since 2002.)

  KT is focusing on another business opportunities using WiBro. KT also thinks that it is difficult for WiBro to expand with only mobile broadband service which provides an internet connection with usb modem or PCMCIA card. KT is trying to develop various mobile service using WiBro. For example, mobile education service was launched for undergraduate students of SKKU. KT announced today, that a full browsing service on a smart phone will be provided. However, I am not sure that the efforts and strategies for expansion of WiBro service would give a great result to KT.

  I am agree that many innovative mobile services like full browsing, mobile education and mobile health service must attract users for WiBro in order to succeed in developed markets. However, why do we have to consider WiBro as the network for the services? There are alternatives like HSDPA and CDMA. LGT succeeded to provide full-browsing service using CDMA EV-DO Rev.A and already attracted 50,000 users for 15 days after launch.

  I am wondering how WiBro or WiMAX service can survive in developed markets.

   KT WiBro attracted 100,000 subscribers in the late November. Although KT launched the WiBro service at June last year, KT had only 5,000 subscribers until last March. However, since last April, KT attracted, on an average, 12,000 subscribers every month.
  
   In Korea, there are three kinds of mobile broadband service. KT WiBro is mobile WiMax service based on data service. Meanwhile, SKT's T LOGIN and KTF's iPlug are HSDPA services based on voice service. SKT and KTF can not push the mobile broadband services because the services share the HSDPA network with voice service. However, because WiBro is a network for only data service, KT might be able to push the service aggresively.

   Although someone says that 100,000 subscribers of KT WiBro are due to KT's aggressive promotion, the acheivement must be the steppingstone for the expansion of mobile WiMax service. In 2008, SKT has an investment plan for WiBro service. I expect the korean mobile broadband market will be exciting in 2008.

   According to the recent conference call of KT, KT got only 4 percent ROI from WiBro(Mobile WiMax) business. While one and half year has passed since commercialization of WiBro, KT was not able to find a bright idea for business expansion. Even if KT has invested about 500 million USD to WiBro Business, the revenue from WiBro was only 20 million USD and the number of subscriber is 70,000. Until last May, the number of subscriber was less than 10,000.

   Last month, The ITU Radio Assembly approved WiBro as an official IMT-2000 Interface. However, no one expects that WiBro will make a fast expansion in Korea. MIC (Ministry of Information and Communication) approved WiBro as only data service. As far, No Voice Serivce on WiBro in Korea.

   I am wondering that WiBro business can be operated with only data service. There is a simmilar example in Korea. In 2001, KT launched Netspot, a wireless broadband service using hotspots. However, the increase of subscribers stopped and the number is about 400,000. I think it is the maximum number of subscriber for mobile and wireless broadband service in Korea.

   Under the agreement with Korean government, KT and SKT should invest more than 500 million USD next year. How can they get sufficient return from the investment?

   Today, The ITU Radio Assembly approved WiBro (Mobile WiMax) as an official IMT-2000 Interface. WiBro became a sixth radio interface of IMT-2000 which has W-CDMA, CDMA2000, TD-SCDMA, EDGE and DECT.

   Korea is one of leading countries for WiBro (Mobile WiMax). KT already launched the WiBro service early this year and got about 60,000 users until last September. In addition, SK Telecom must invest a lot to WiBro under aggrement with MIC (Ministry of Information and Communication). In addition, there are many WiBro equipment manufacturers including Samsung Electronics, Posdata. Korean government and companies expect that WiBro would be extended to global markets.

   However, there are some barriers that disturb WiBro to be pomoted to usual people. One of barriers is the prohibition of voice calling function on WiBro devices. Korean government granted WiBro license to KT and SK Telecom whth conditions attached that WiBro should be used for only data service, not voice service.

   I am wondering whether Korean government will change the existing rule that WiBro should be used for only data service. WiBro as a standard of IMT-2000 can be used for data & voice service.

   This issue might cause great impact on korean communication market. What is the final conclusion??
