NTT, NTT docomo and NEC have developed a distributed MIMO system that uses the 28 GHz band, in which the system itself grasps environmental information such as radio propagation conditions and the location of mobile terminals within the area, and dynamically adjusts the distributed antennas of base stations according to the environment. We conducted a demonstration experiment of the technology to switch to , and succeeded for the first time in the world.
He showed the possibility of using high-frequency band wireless for stable large-capacity wireless transmission even in environments with many shields such as shopping malls and factories.
