We aim to create fast (1 Gbps wireless LAN, 10 Gbps media transmission) and flexible (software wireless platform that can accommodate low-speed sensor networks) wireless home networks that enhances FTTH, enabling the use of home networks and wireless access communications, outside the home, across different systems.
To implement giga-bit-class wireless home networks that can connect anywhere in the home, we are conducting R&D on a multi-user MIMO technology. This technology is able to achieve high system throughput by using multiple antennas on the wireless LAN base station for precision control over beam-forming and perform space-division multiple-access for multiple terminals.
NTT has researched and developed wireless transceivers that cover all four channels allocated in the 60-GHz band. Our technology will realize near-field high-speed transmission of gigabyte class content from kiosk terminals, recorders, and home gateways to portable devices.
We are conducting R&D on a flexible wireless system that applies cognitive wireless technology in order to implement wireless access that accommodates all wireless schemes from low-speed ubiquitous data to high-speed wireless LAN, without requiring the user to be aware of it.
