KDDI's 3G Mobile Phone Puts Feasibility First
Posted: 22-Apr-2002 [Source: AsiaBizTech]

[Japan's KDDI focuses on service coverage, terminals, and content as ways to give its newly launched CDMA2000 1x service a competitive edge.]

bu Shinsuke Kawasaki, Tokyo -- "On April 1, KDDI Corp. launched its third-generation mobile phone (3G) service, "CDMA2000 1x." The company aims at gaining popularity by keeping down the prices of terminals, but not by making users conscious of 3G and the capabilities it has to offer, but by pursuing a different strategy from the preceding "FOMA" of NTT DoCoMo Inc.

Nevertheless, technically speaking, FOMA is not the real rival of 1x. Rather, KDDI is more conscious of J-Phone Group, which is fast catching users with its "Sha-Mail" service, which can send and receive e-mails with pictures.

Primary Feature is an Enhanced Version of CdmaOne

The most significant feature of the 1x service is the data communications speed being doubled from the conventional speed to a maximum of 144kbps, utilizing the existing network of "cdmaOne" mobile phone service. There is a clear distinction from NTT DoCoMo's FOMA, for which the network was developed from the word "go," in such areas as expansion of the service area and the terminals that are released."
