5G
5th-Generation Wireless Systems (abbreviated 5G) is the marketing term for technologies that satisfy ITU IMT-2020 requirements and 3GPP Release 15. Key features of 5G include high throughput, low latency, high mobility and high connection density. 5G will use additional spectrum in the existing LTE frequency range (600 MHz to 6 GHz) and Millimeter wave bands (24-86 GHz), which can support data rates of up to 20 gigabits per second (Gbit/s). 5G infrastructure will use Massive MIMO (Multiple Input Multiple Output) to significantly increase network capacity.
Future
The future is what will happen in the time after the present. Its arrival is considered inevitable due to the existence of time and the laws of physics. Due to the apparent nature of reality and the unavoidability of the future, everything that currently exists and will exist can be categorized as either permanent, meaning that it will exist forever, or temporary, meaning that it will end.

In the Occidental view, which uses a linear conception of time, the future is the portion of the projected time line that is anticipated to occur. In special relativity, the future is considered absolute future, or the future light cone.
