5G

5G is the fifth generation of cellular mobile communications. It succeeds the 4G (LTE/WiMax), 3G (UMTS) and 2G (GSM) systems.5Gperformance targets high data rate, reduced latency, energy saving, cost reduction, higher system capacity, and massive device connectivity. The first phase of5Gspecifications in Release-15 will be completed by April 2019 to accommodate the early commercial deployment. The second phase in Release-16 is due to be completed by April 2020 for submission to the International Telecommunication Union (ITU) as a candidate of IMT-2020 technology.
The ITU IMT-2020 specification demands speeds up to 20 gigabits per second, achievable with millimeter waves of 15 gigahertz and higher frequency. 3GPP is going to submit5GNR (New Radio) as its 5G communication standard proposal.5GNR can include lower frequencies, from 600 MHz to 6 GHz. However, the speeds in early deployments, using5GNR software on 4G hardware (non-standalone), are only slightly higher than new 4G systems, estimated at 15% to 50% faster. Simulation of standalone eMBB deployments showed improved throughput by 150% below 6 GHz and by nearly 20x at millimeter waves.
