擴大3G領先優勢，KDDI再推電影傳輸服務

為拉大與DoCoMo的領先距離，KDDI 20日再推出兩款可照相手機，並將於下週開始搶先提供電影傳輸服務。由於網路覆蓋率高、手機價格便宜，加上電池壽命較長，KDDI 3G服務雖晚DoCoMo半年推出，但用戶數卻遙遙領先，目前已超過200萬。

KDDI計畫在3年內投資2,000億日圓升級目前CDMA2000 1x基地台到EV-DO。分析師也認為直接升級將可為KDDI節省不少成本。KDDI預計本會計年度結束時，1x用戶數將達到700萬戶。至於DoCoMo則將花5倍的金錢在全國興建新的FOMA基地台。

KDDI的高速網路服務提供的傳輸速度僅有DoCoMo FOMA的一半，但手機待機時間卻超過200小時，為DoCoMo的四倍。美林證券分析師Yasumasa Goda表示，嚴格來說，KDDI提供的並不算3G，只能說是2.5G，但卻比DoCoMo更符合市場需求。

DoCoMo的FOMA讓用戶可以在通話同時交換雙方照片對於那些希望輕鬆且隱藏身份的人來說一點吸引力也沒有。Goda指出，對電話用戶來說，特別是接聽的一方，並不希望自已的大頭照秀在來電者的手機上，因此FOMA的TV-telephone概念行不通。

KDDI還沒真正面臨2G升3G的瓶頸
當CDMS2000 1x 升級到CDMA 2000 EV-DO的時候
同樣的問題也會發生在KDDI的身上
像是涵蓋率不足, 手機的問題, 用戶接受度的問題等等

事實上DoCoMo是全世界唯一一家真正面臨升級3G系統問題的業者
韓國現在也正野心勃勃的想要全面導入CDMA 2000 EV-DO
結果初步就非常不理想, 我有一篇英文的報導可以提供給有興趣的網友參考

目前還沒有一家真正用CDMA 2000 EV-DO營運的系統業者
但是不可諱言的CDMA升級到CDMA 1x比GSM升級到GPRS要容易的多
這也是為何KDDI在推CDMA 1x順利的原因

韓國現在也正野心勃勃的想要全面導入CDMA 2000 EV-DO
結果初步就非常不理想, 我有一篇英文的報導可以提供給有興趣的網友參考

Korea’s EV-DO 3G service struggling with slow penetration
= = = = = = = = =
Korea’s ambitious plan to commercialize cdma2000 1x EV-DO faces a serious challenge as users appear satisfied with the current mobile service and unwilling to upgrade their phones to upscale EV-DO models.

SK Telecom, the country’s largest mobile carrier, and KTF, the No. 2 player, launched EV-DO in the first half of this year and tried to create a boom for the high-speed mobile Internet service, but subscribers remain unimpressed.

In theory, EV-DO can deliver data at up to 2.4Mbps, 16 times faster than the mainstream third-generation (3G) mobile technology of cdma2000 1x capable of offering 144Kbps transmission speed.

Korea’s mobile carriers eagerly showcased their EV-DO technologies and video-on-demand services during the World Cup finals in June to boost global brand recognition and capture the attention of foreign tourists and media.

The problem is that local subscribers have been slow to embrace EV-DO, raising the question of whether Korea’s mobile service is truly 3G as government officials claim.

The Ministry of Information and Communication argues that Korea’s current mobile phone service, which is called cdma2000 1x, is 3G. SK Telecom launched cdma2001 1x in October 2000, followed by similar moves by other carriers. The bulk of mobile phone users in Korea are now equipped with handsets designed for cdma2000 1x, but foreign media often dub the service as 2.5G, not a full-fledged 3G service that supposedly offers uninterrupted videophone and other multimedia transmission over the mobile network.

Information ministry officials and U.S.-based wireless technology firm Qualcomm Inc. refutes that definition, citing the revised 3G benchmark set by the International Telecommunication Union (ITU). They claim that cdma2000 1x is capable of offering 144Kbps service, which meets the ITU standard to be categorized as 3G.

Technically, the cdma2000 1x available in Korea is a 3G service, but it is stretching the truth to claim that subscribers in Korea are exchanging video files or other multimedia content over the network. After all, 144Kbps is not intended for super-fast multimedia file transmission. EV-DO might do the job, but few people have EV-DO handsets in Korea.

The underlying issue is that Korea’s government officials are quick to brag about cutting-edge mobile technologies such as EV-DO, videophone and other multimedia services over the 3G network infrastructure.

But a majority of mobile phone subscribers are stuck with simple SMS (short messaging service), background image and ring tone downloads. Surfing the Web through mobile handsets is technically possible, but those who venture to do so have to have deep pockets since the mobile phone rates are applied. Patience - since the maximum speed of 144Kbps under ideal conditions is not fast enough - is also highly appreciated for mobile Internet.

SK Telecom launched the initial-stage commercial cdma2000 1x EV-DO service in the city of Incheon in January this year, heating up the race for faster wireless Internet services.

But SK Telecom’s EV-DO service in January was limited to wireless modems, not handsets. The company attempted to jumpstart mobile handset-based service during the World Cup finals in June.

The carrier, which kicked off a testing-level service of EV-DO in November last year, said it would expand the service into Seoul and other major cities. It said EV-DO will be available in 83 cities across the nation toward the end of the year.

As of early September, the number of SK Telecom’s EV-DO subscribers is 1,200. KTF is not faring well, either. Its EV-DO subscribers are 14,000, a disappointing figure in consideration of its original target of 800,000 by year-end.

SK Telecom and KTF, of course, blame the much-delayed roll-out of EV-DO handsets by Samsung Electronics and LG Electronics.

Mass production of Samsung’s EV-DO handset, named SCH-E100, started in late August, while LG’s KH5000 was available in the market from late July.

Analysts said local subscribers are reluctant to spend money on the mobile Internet whose rates are still regarded as expensive. High-speed Internet, meanwhile, is widely available in the office, at home and on the street in Korea, making the mobile Internet service less appealing in terms of rates and service quality.

Another reason is that the so-called "killer" EV-DO content is still scarce. Mainstream mobile phone users simply do not find any motive to purchase new EV-DO handsets to see a crude video image while they can watch as many high-quality movie clips as they want through broadband Internet services at home for a flat rate.

The race for EV-DO by SK Telecom and KTF came as voice-oriented second-generation wireless service is reaching saturation point and subscribers begin to show interest in wireless data services.

LG Telecom, a mobile carrier competing with SK Telecom and KTF, does not offer EV-DO service.

With the EV-DO service struggling with the slow penetration in the market, a new 3G service is set to be introduced in Korea in the second half of next year. The so-called 2GHz 3G service based on W-CDMA technology (otherwise known as IMT-2000 here) will be launched by KT ICOM, a mobile unit of KT Corp., and SK IMT, a unit of SK Telecom.

The Korean government awarded the two W-CDMA licenses to KT and SK Telecom in 2000 in the name of allocating 3G spectrum to carriers. But the next year, it gave another license to LG Telecom for 3G service based on cdma2000 technology.

Strange as it may sound, SK Telecom, KTF and LG Telecom are currently offering "technically correct" 3G services based on cdma2000 1x, without using the 3G licenses awarded by the Korean government.
