Reliable enough to start your morning with. Toast it again tomorrow.
Summary
NTT DOCOMO, NEC, and NTT have developed a 6G-ready mmWave technology that enables multiple high-speed vehicles to maintain stable communications simultaneously using the 40 GHz band. The technology combines distributed MIMO with pre-compensation of transmit frequency and timing. A demonstration trial was conducted to validate the system's effectiveness for high-mobility multi-vehicle connectivity, targeting future 6G network applications.
