5G represents the next milestone in mobile communications, targeting more traffic, increased capacity, reduced latency, and energy consumption through various technologies such as massive multiple-in and multiple-out (MIMO) and beam-forming antenna arrays, mm-Wave spectrum use, and carrier aggregation. NI AWR software helps engineers develop the technologies that will make these advances possible.
