Targeted annual turnover for 2005 : 10 Trillion KRW. Various new applications such as MelOn (music service), mobile cyworld (community service), Cizel (movie service), GXG (mobile game), convergence of online and mobile services, and flexible pricing program vitalized mobile internet usage. MOU : average voice call time per month
&lt;number&gt; @ Finpro ry As of September 2005, 42.8% of mobile phone owners aged 12 years or over have used the mobile internet at least once within the previous 6 months. The percentage of mobile internet users is the highest among mobile phone owners aged 12~19 years(87%) followed by 20’s(73.1%) and 30’s(42.7%). Users access to the mobile internet for 52.3 minutes and 6.5 times a week on the average and spend 5.7 EUR/month for accessing the mobile internet, which is 12.2% of the total spending for mobile phone use a month. Most popular mobile internet contents are ringtone/melody download(96.8%), music(45.4%), image download/transmission(42.1%), and game(37.1%). The most popular pricing program for the mobile internet use is ‘time-based charge’ system followed by fixed charge’ and ‘accessed-based charge’ system. Over 70 % of mobile internet users have purchased services and goods through the mobile internet. In 2004, 69.8% of wireless internet users connected to the wireless internet less than 5 times per week. And all wireless internet users access to it 4.9 times a week on the average.
&lt;number&gt; @ Finpro ry In 2004, data sales accounted for 19% of the total mobile service sales while the revenue from voice service stood at the remaining 81%. Data sales is expected to continue growing and reach 30% of the total mobile service by 2008. There is a trend toward more data usage if subscribers own advanced multimedia handsets. Mobile operators’ mobile internet sales out of total non-voice sales were 51%(SKT), 64%(KTF), and 36%(LGT) respectively in 2Q 2005. Ratio of mobile internet sales is likely to increase when 3G services with fast data transmission speed fully deploys in 2006. Non-voice services means airtime, SMS, per-download charge, and value-added services including CID and ringback-tone service
&lt;number&gt; @ Finpro ry
Mobile phone sales in the domestic market amounted to 15.9 million units in 2004 and is estimated to reach 13 ~ 16 million in 2005. Camera phones took more than 70% of the total sales, and the market was divided by Samsung, LG, and Pantech with the market share of 50%, 25%, and 15% respectively. Mobile handset production in Korea is more sensitive to overseas demand than domestic demand. Domestic sales accounts for only around 10% of the total production in the country and 90% for overseas sales. Please note the discrepancy in figures between Table 6 and 7. MIC figure is much less than National Statistics figure. Mostly MIC figure is used.
&lt;number&gt; @ Finpro ry Three major manufacturers, Samsung Electronics, LG Electronics, and Pantech & Curitel, are controlling 80% of the mobile handset market in Korea.

Wibro follows 802.16e standards. Wibro is expected to overcome non-mobility of fixed broadband, low speed and high price of mobile internet, and low coverage of WLAN.
License fee for Wibro Operators : KT - 125.8 bil KRW(100 mil Euro), SKT – 117 bil KRW (93 mil EUR)
Initial business model is a fee for internet access to mobile internet, WLAN, and fixed broadband internet. When the market it ready, value-added service will be developed for revenue generation. Initial business model is a fee for internet access to mobile internet, WLAN, and fixed broadband internet. When the market it ready, value-added service will be developed for revenue generation.
Although KT has its subsidiary ‘KTF’ that is a mobile operator, KT itself dose not have a mobile business other than WLAN business. In order to cope with the convergence era, KT has been eager to enter the mobile business. Wibro is seen as a means to give a mobile wing to KT, which is why KT considers it an essential for its future business.
SKT plans to adopt IPv6 over Wibro, but investment on that will start from 2006, aiming to achieve 30Mbps in the beginning – 50Mbps by 2008 – 100Mbps by 2010.
It takes 40 seconds to send 1MB MM over the mobile NW while it takes only 8 seconds over Wibro. To download a 4MB (1 packet=50byte) MP3 over the current mobile NW, it costs 120000KRW (100 EUR). SKT sees HSDPA more important than Wibro as ;HSDPA is easier to realize mobile TPS, cheaper for NW investment, and users prefer a mobile phone type terminal. Mobile phone type terminal is preferred. Due to price and mobility, users are not likely to buy two handsets for similar services. HSDPA can offer nationwide voice and data services, and therefore is likely to be preferred by users. Once selected, a handset has a lock-in effect.
SKT’s june/Nate on CDMA network, its satellite DMB through TU Media, Wibro, and HSDPA all offer mobile TV service. SK Networks is in charge of handset distribution of SK Telecom. SK Communications and Widerthan.com are contents and solution providers.

Alticast and Air Code (both Korean companies) are developing solutions solutions to be ported on the terminal and broadcasting server for future data service over satellite DMB. Together with ETRI and SK Telecom, the two companies are developing standards for data service for satellite DMB. Alticast supplied middleware platform for MHP satellite broadcasting service and OCAP cable digital TV.
6 operators do not have terminal distribution channel yet and are unsure how to build the network. MIC and the 6 operators want the three mobile operators to distribute the terminal, but the mobile operators do not see the merits of doing so. Mobile operators have know-how to build Gap Fillers and also have spaces to install them, which terrestrial DMB operators lack. While mobile operators want charged service for terrestrial DMB, terrestrial DMB operators (their trade unions in specific) insist on free of charge service. From mobile operators’ point of view, revenue comes from subscription fee. From terrestrial DMB operators’ point of view, revenue comes from advertising fee of enterprises.
MOT: Multimedie Object Transfer. MOT is a protocol that enables file transfer and replay of the received file. IP Tunneling is an IP-based data transfer technology. IP-based data transfer on the Web can be done over the broadcasting network (terrestrial DMB network) using IP Tunneling technology. Using MOT and IP Tunneling, new dimensions of data broadcasting is possible through terrestrial DMB. For example, lyrics of songs being heard over the terrestrial DMB can be sent in text file to the user terminal simultaneously. Pictures of singers can be shown in Slide Show, as well.
Samsung and Nortel have supplied 900 BSTs to SKT during 1H 2005 Targeted coverage within 2005 are 23 cities by SKT and 17 cities by KTF. SKT’s CDMA network is based on 800MHz while KTF and LGT’s are on 1.8GHz. WCDMA and EVDV are on 2GHz bandwidth. Therefore, DMDB handsets that guarantee interoperability between WCDMA and CDMA must be released in order to allow WCDMA to work nationwide. SKT’s target was to gain 200,000 subscribers by the end of 2005 while KTF targeted 50,000 subscribers, which all failed.
&lt;number&gt; @ Finpro ry

HY-SDR Center is world-reputed R&D center in SDR technology.
Killer applications in 2004 were more sophisticated ring tones (music), characters, and games. Downloading MP3 music files through wire-wireless converged portals gained popularity. Out of the total mobile subscribers, actual users of mobile internet are only 14 million. How to induce the rest, mostly composed of over age 40s, to use the mobile internet is the key to more revenue generation. Telematic and mobile banking are the new services they can use. Voice call has reached saturation. Operators are focusing on new non-voice services to sustain growth. Despite the success of mobile internet service in Korea, only a few top mobile Content Providers are successful and taking the fair share of the growing pie. 7.4% of the total CPs have more than 2 billion KRW (1.4 million EUR) of annual turnover. About 81% of the total CPs have not reached break-even yet. There are over 1,300 CPs competing in the market. 67% of the total CPs are employing less than 20 people. 70% of the total CPs have less than 500 million KRW (400,000 EUR) of paid-in-capital. SKT has 4,670 menus and 680,000 contents in its mobile internet service.
Most popular mobile internet contents are ring tone/melody download(96.8%), followed by music(45.4%), picture download/transmission(42.1%), and game(37.1%).
&lt;number&gt; @ Finpro ry Mobile finance service launched by SKT and KTF in 2001 has not been very successful in Korea until mobile banking service hit the market. The first form was a mobile payment service through credit card built in handsets. LG Telecom, the country&apos;s third-largest mobile carrier, sparked the race for mobile financial services late last year, expanding its user base with Bank On, a full mobile banking solution for Kookmin Bank customers. LG, which has long faced an uphill battle to compete with its bigger rivals, benefited from the mobile banking service after staging joint marketing campaigns with Kookmin, the country&apos;s largest lender.IC chip based mobile finance service or mobile banking service was introduced in Korea in 2003. As of September 2005, 85.7% of mobile internet users are aware of mobile banking service while only 8.4% of those actually use the service. (Source: NIDA)
