Fifth-generation mobile communication technology (English: 5th generation mobile networks or 5th generation wireless systems, 5th-Generation, abbreviated or 5G 5G technologies) is the latest generation cellular mobile communication technology, i.e. is 4G (LTE-A, WiMax), 3G ( UMTS, after extending LTE) and 2G (GSM) system. 5G performance goal is high data rates, reduced latency, save energy, reduce cost, increase system capacity and large-scale devices. 5G in the first phase of Release-15 specification is to accommodate early commercial deployment. The second phase of Release-16 will be completed by April 2020, submitted to the International Telecommunication Union (ITU) [1] as a candidate for IMT-2020 technology. ITU IMT-2020 specification requires speeds up to 20 Gbit / s, it can realize a wide channel bandwidth and a large capacity MIMO.
