Description

5G is the fifth generation of cellular mobile communications. It succeeds the 4G (LTE/WiMax), 3G (UMTS) and 2G (GSM) systems. 5G performance targets high data rate, reduced latency, energy saving, cost reduction, higher system capacity, and massive device connectivity. The first phase of 5G specifications in Release-15 will be completed by March 2019 to accommodate the early commercial deployment. The second phase in Release-16 is due to be completed by March 2020 for submission to the International Telecommunication Union (ITU) as a candidate of IMT-2020 technology.
The ITU IMT-2020 specification demand for speeds up to 20 gigabits per second, achievable with millimeter waves of 15 gigahertz and higher frequency. 3GPP is going to submit 5G NR (New Radio) as its 5G communication standard proposal. 5G New Radio can include lower frequencies, from 600 MHz to 6 GHz. However, the speeds in these lower frequencies are only slightly higher than new 4G systems, estimated at 15% to 50% faster.
