The high-speed mobile broadband service will be available in half of Japan by 2014.
NTT DoCoMo plans to launch high-speed cellular data services based on LTE (Long Term Evolution) technology in December 2010, it said Thursday.
LTE is an IP-based system seen as a replacement for 3G-based HSPA (High Speed Packet Access) and its introduction is expected to reduce the per-byte cost of data communications.
The Japanese service will initially be aimed at PC users, with DoCoMo offering card-type terminals for laptops, said Ryuji Yamada, president and CEO of NTT DoCoMo at a Tokyo news conference. It will be expanded to include handset terminals from 2011, he said. Those terminals will be dual-mode devices that use LTE networks where available and fall back to 3G networks to provide nationwide coverage.
By 2014 the carrier plans to provide LTE service to 50 percent of Japan from around 20,000 base stations.
