Satellite MIMO: NTT and JAXA Prove a World-First Technology That Could Connect Every Corner of the Planet

NTT and JAXA have completed the world's first orbital demonstration of satellite MIMO communication and IoT sensing technology aboard a low-Earth orbit satellite. By applying MIMO, the same technology that speeds up your smartphone, to space, they aim to double satellite data transmission capacity. The breakthrough could bring IoT connectivity to mountains, oceans, and remote islands where no cell towers exist.
