KDDI Is Preparing and Expanding EV-DO Rev. A and Preparing for the Reorganization of the 800MHz Bandwidth While Setting Policies for the Next Generation Systems.
KDDI has differentiated itself from other carriers with the CDMA2000 1x EV-DO (“EV-DO”) format* currently used for its “WIN” services. Progress in establishing and expanding coverage for EV-DO Rev. A, an upgraded version of EV-DO, has enabled us to cover virtually all major regions of all 47 prefectures in Japan as of the end of March 2009. EV-DO Rev. A downlink speed has been improved to a maximum of 3.1Mbps, and uplink speed to a maximum of 1.8Mbps. In addition to expanding and enhancing coverage to improve transmission quality in response to rising subscriber numbers and increased demand for data communications,
*The CDMA2000 1xEV-DO Format Because EV-DO is a technology specifically for data communications, it is suited for highspeed, large-volume data transmission. With the introduction of EV-DO, KDDI was able to significantly lower per-bit transmission costs. Drawing on the strengths of the EV-DO infrastructure, KDDI has been able to stay ahead of other carriers in offering appealing services such as “EZ Chaku-Uta-Full?” and attractive price plans such as the “Double-Teigaku-Light” (Packet Flat-rate) plan.
KDDI is also expanding the 2GHz band, and working to prepare for the allocation of a new 800MHz band, based on the 800MHz band reorganization. The reorganization of the 800MHz band calls for switching the direction of the current uplink (handset to base station) and downlink (base station to handset), and reallocating the current narrow and scattered frequencies into solid blocks by July 2012. Currently, the 800MHz band is KDDI’s main operating band, but the Company is pressing ahead with expansion of 2GHz band coverage, and also is increasing the area coverage for the new 800MHz band in preparation for full conversion by July 2012.
