In the wake of Japan's mobile number portability (MNP) rules, KDDI, Japan's second-largest operator, is witnessing a significant boost in net subscriber numbers, according to the CDMA Development Group (CDG).
Since MNP was introduced in Japan in October, KDDI gained 324,900 net subscribers in the month of November, representing more than 82% of the total net additions or six times the amount of subscribers that were added by the other two competing networks, said the CDG.
"The benefits of CDMA2000 have become clear to customers," said Perry LaForge, executive director of the CDG. "Now that it is significantly easier for Japanese customers to change their mobile service provider, they are free to choose the services and user experience that best suit their needs.
"CDMA2000 is delivering (third generation) 3G broadband service years ahead of competing technologies and currently offers the most valuable selection of mobile multimedia applications.
"Once KDDI begins offering advanced mobile broadband data services using their new 1x (evolution-data optimized) EV-DO revision A (Rev. A) network later this month, competing service providers can expect increased attrition."
KDDI is expected to attract the majority of the customers who have opted to change their mobile service after October's ruling, said the CDG. The company is committed to the operation of their CDMA2000 network.
Tohru Kawai, vice president and general manager, "au" business sector of KDDI, said, "KDDI is pleased to see the growing demand for our advanced CDMA2000 services. Having our competitors' customers choose our network, services and customer care is a testament of the value that we provide."
EV-DO Rev. A was standardized by the Third Generation Partnership Project 2 (3GPP2) and was enhanced to support delay sensitive, symmetric and real-time applications. Beyond a significant reduction in latency, Rev. A's most compelling benefit will be increased uplink speeds up to 1.8 Mbps and downlink speeds up to 3.1 Mbps, said the CDG.

As an all-Internet Protocol (IP) platform, Rev. A will allow the new network to support higher voice capacity, lower operating costs, faster development of applications and services and a wider range of auxiliary access networks.
