This paper proposes and conceptualizes the
use of Quadrature baseband (QBB) beamforming in 5G
mmWave Networks as an alternative to Radio
Frequency (RF) beamforming. The QBB beamforming is
compared in terms of performance to the RF
beamforming using antenna gain, throughput and
bandwidth as performance metrics. The concept
considers beamforming at QBB for four (4) arrayed
antennas propagating signals in the mmWave
frequencies, at 28GHz
