3D Elevation Beamforming
Three-Dimensional Elevation and Azimuth Joint Beam Steering
Controls both vertical elevation tilt and horizontal azimuth steering simultaneously in Massive MIMO arrays to serve aerial drones and high-rise office towers.
Technical Explanation
Classical base station antennas featured fixed mechanical down-tilt optimized strictly for ground users. Rel-18 3D Elevation Beamforming leverages two-dimensional planar antenna arrays (e.g. 16x8 elements) to steer sharp pencil beams in both horizontal azimuth and vertical elevation, serving high-rise skyscrapers, airborne drones, and ground pedestrians simultaneously without inter-tier interference.
Key Functions
- Steers narrow pencil beams dynamically in both vertical tilt and horizontal azimuth
- Provides dedicated high-capacity coverage to top floors of urban skyscrapers
- Maintains simultaneous interference-free links to airborne drones and ground users
- Maximizes 3D spatial reuse across multi-story urban environments
