TOKYO-Japanese telecom firm KDDI Corp. has agreed to cooperate with China Unicom Ltd. on mobile-phone and Internet access technologies, according to international press reports.
KDDI uses CDMA technology, and China Unicom last month signed contracts with wireless vendors to build out the first CDMA network in China.
The Japanese carrier plans to launch 1x service, which offers higher data rates than currently available, later this year to compete with rival NTT DoCoMo.
