MM-wave radio, a key enabler of 5G communication

摘要

In this paper, we evaluate a few millimeter-wave (mm-Wave) frequency bands as candidates for cellular mobile communication and demonstrate how selection of frequency band, size of base station (BS) phased array, coverage range, and number of simultaneous users that can be supported are tightly related. One of the major differences of 5G vs. legacy cellular generations is that the radio is operating at a significantly higher frequency; hence, we review the required technologies from integrated circuits to packaging and printed circuit boards (PCB) along with tradeoff among possible choices.
