High-gain narrow-beam antennas or beamformed antenna arrays will likely be used in millimeter-wave (mmWave) bands and 5G to mitigate the high path loss. Since many multipath components may be excluded by the narrow beam, the mmWave radio channel (consisting of the transmit antenna, the propagation channels, and the receive antenna) strongly depends on the beamwidth, orientation, and shape of the narrow beam. In this article, a procedure is proposed to measure and model the channels vs.

- * The paper focuses on understanding the impact of computation power on energy efficiency, particularly exploring the significance of the Landauer principle.
- * Simulation findings show that over 50% of energy consumption at 5G small cell base stations is due to computation power, with potential consumption reaching 800 watts when using massive MIMO technology.
