Company Overview
NTT DOCOMO is Japan's largest telecommunications company. Established in 1992, DOCOMO launched its first digital cellular phone service the next year and the world's first mobile Internet-services platform in 1999. It helped to establish the W-CDMA standard for mobile communications and then kick off the first 3G service based on this standard in 2001. The company also introduced one of the earliest commercial LTE services in 2010.
DOCOMO is a world-leading developer of 5G networks, which it plans to deploy in the 2020s by leveraging network function virtualization (NFV) and other technologies. DOCOMO is also driving innovation in NFC infrastructure and services, emerging IoT solutions and many other mobile-related initiatives.
DOCOMO launched 5G mmWave services in September 2020, later adding Sub-6 GHz n77 and n79 in 2C carrier aggregation in December 2020.
