Multiple radio stations are coordinated from terminal movement data to adjust streams and keep millimeter-wave links stable at high capacity.
Multiple conductive paths and a switch circuit let an RIS unit cell keep 180-degree reflection phase across incident angles, reducing signal loss.
Local SVD feedback converts undersized CoBF antenna links into virtual channels, cutting CSI overhead while enabling zero multi-user interference.
Vertical antenna placement at 3-8 m with wide horizontal beams and slight downtilt expands distributed-MIMO coverage where installation space is limited.
Distributed access nodes and central beam weight computation recover multipath uplinks and form user beams with lower satellite complexity.
Multiple directional donor antennas link to different base stations to ease hotspot congestion by aggregating bandwidth without new cell infrastructure.
