[Au to offer 1xEV-DO data communication technology in the 2GHz band beginning April 2003 in Japan's Kanto region. ]
Tokyo -- "Au group (KDDI Corp. and Okinawa Cellular Telephone Co.) announced on May 10 that it will implement the "1x evolution-data only (1xEV-DO)" system for its third-generation (3G) mobile phone service using 2GHz band.
The test service is to start in April 2003, according to the announcement.
1xEV-DO is a packet communication technology based on cdmaOne, and is exclusively for data communication. The data communication speed for download is 600kbps on the average, and the maximum speed reaches up to 2.4Mbps. It is based on the "high data rate" developed by Qualcomm Inc. of the United States.
The 2GHz band is the new frequency band allocated by Ministry of Public Management, Home Affairs, Posts and Telecommunications for the use of 3G services. NTT DoCoMo Inc. is now offering "FOMA" service with the 2GHz band, and J-Phone Co., Ltd. is also planning to offer its 3G service like FOMA using W-CDMA starting in December 2002. Au on the other hand introduced its 3G service "1x" in April of this year using the 800MHz band, which is currently in use for cdmaOne. As for the 2GHz band service, the group has not announced any details until now except for the fact that it plans to start offering the service in September 2002."
