'5G mobile networks (or 5G network) —the next-generation standard for wireless communications—are scheduled to follow (but not replace) current 4G networks with vastly increased capacity, lower latency, and faster speeds. Anticipated between 2019 and 2020, some 5G networks will initially operate in a high-frequency band of the wireless spectrum — between 28 GHz and 38 GHz — also known as the millimeter wave (mmWave) spectrum.
The new 5G networks will be able to transmit very large amounts of data short distances. However, 5G is also expected to work in low spectrum frequencies such as 600 MHz as well as unlicensed frequencies such as the 3.5 GHz spectrum.'
