KDDI Eyes Method for Advanced Mobile
KDDI Corp. intends to maintain the CDMA 2000 method, used for the current 3G mobile service offerings, for voice communications in future advanced mobile services, company officials have said according to JiJi press. For data transmission, however, KDDI plans to adopt the Long Term Evolution, or LTE, technology, an internationally supported method to be compatible with the wideband code division multiple access, or W-CDMA, mobile method now used by its rivals NTT DoCoMo and Softbank Mobile the officials said.
While Japan’s telecommunications ministry mulling deregulation to allow users to switch their mobile carriers by changing SIM cards, no unification of the next-generation mobile platforms is likely to delay the realization of that convenience.
As the 3.9G method is viewed as a transitional technology to the 4G system, which offers transmission speeds as fast as fiber-optic networks, KDDI apparently hopes to delay fully unifying the specifications until the 4G era or later. Via: JCN
