Beamforming
Steering an antenna array's energy toward a device.
Definitions only — a term explained here is not a service we sell.
Beamforming uses an antenna array to concentrate radio energy in a direction, instead of spreading it evenly. The array adjusts the phase of its elements so the signal adds up toward the device.
Why it matters
Beamforming raises the signal strength and reduces interference in the direction it serves. It does not create coverage where there is no path, and it depends on the device and the network agreeing on the beam.
What to check
Treat a beamforming claim as an antenna and software claim, not a coverage claim. Ask which bands and which 5G modes support it, and test in the deployment geometry rather than at the base station. The gNodeB term covers the base station.
