On the Optimal Beamwidth of UAV-Assisted Networks Operating at Millimeter Waves
On the Optimal Beamwidth of UAV-Assisted Networks Operating at Millimeter Waves
The millimeter-wave (mm-wave) bands enable very large antenna arrays that can generate narrow beams for beamforming and spatial multiplexing. However, directionality introduces beam misalignment and leads to reduced energy efficiency. Thus, employing the narrowest possible beam in a cell may not necessarily imply maximum coverage. The objective of this work …
