Abstract
As the mmWave network is expected to be a promising paradigm in future wireless networks, in this chapter, we provide a comprehensive survey of mmWave networks, especially focusing on the beamforming technology. Particularly, we review mmWave networks in four sections: (1) characteristics of mmWave communication from multiple aspects, including bandwidth, path loss, channel sparsity, antenna directionality, and blockage effect; (2) state-of-the-art beamforming technologies, including analog beamforming, digital beamforming, and hybrid beamforming; (3) current beamforming training protocol in the celebrated 802.11ad standard, including detailed operations and their goals; and (4) multi-armed bandit theory, including its definition and potential applications in mmWave networks.
