CDMA operator KDDI to adopt LTE?

4 Apr 2008

Japan’s sole CDMA network operator KDDI Corp is reported to be considering plans to abandon the technology’s standard upgrade path to ultra mobile broadband (UMB), and migrate to 3GPP’s long term evolution (LTE) technology instead. UMB is the working title within 3GPP2 to improve the CDMA2000 mobile phone standard for next generation applications and requirements. LTE is the alternative 3GPP project for the evolution of UMTS. Unnamed sources in the Yomiuri Shimbun newspaper are quoted as saying that KDDI is seriously considering the move, in light of its growing belief that LTE will become the global standard for next generation mobile systems. The Japanese cellco has long been a cornerstone of CDMA’s development, playing a pivotal role in the evolution of the technology, and currently controls a significant share of global CDMA users.
