5G refers to the fifth-generation mobile communications network and is thus the direct successor to LTE (4G) and UMTS (3G). The new mobile communications standard is therefore not a completely new technology for the time being. Like its predecessors, the 5G network uses frequencies between 700 MHz and 2.6 GHz for data transmission. However, the frequency range between 3.4 and 3.7 GHz will be used for the first time. New technological processes such as beamforming largely compensate for the physical disadvantages of the low and high frequency ranges and ultimately create a fast and powerful network with greater range.
