5G (5th generation mobile networks or 5th generation wireless systems) denotes the next major phase of mobile telecommunications standards beyond the current4G (https://en.wikipedia.org/wiki/4G)/IMT-Advanced (https://en.wikipedia.org/wiki/IMT-Advanced) standards.
NGMN Alliance or Next Generation Mobile Networks Alliance (https://en.wikipedia.org/wiki/Next_Generation_Mobile_Networks) define 5G network requirements as:
Data rates of several tens of Mb/s should be supported for tens of thousands of users.
1 Gbit/s to be offered, simultaneously to tens of workers on the same office floor.
Several hundreds of thousands of simultaneous connections to be supported for massive sensor deployments.
Spectral efficiency should be significantly enhanced compared to 4G.
Coverage should be improved.
Signalling efficiency enhanced.
Latency should be significantly reduced compared to LTE.[1] (https://en.wikipedia.org/wiki/5G#cite_note-1)
Next Generation Mobile Networks Alliance (https://en.wikipedia.org/wiki/Next_Generation_Mobile_Networks) feel that 5G should be rolled out by 2020 to meet business and consumer demands.[2] (https://en.wikipedia.org/wiki/5G#cite_note-2) In addition to simply providing faster speeds, they predict that 5G networks will also need to meet the needs of new use-cases such as the Internet of Things (https://en.wikipedia.org/wiki/Internet_of_Things) as well as broadcast-like services and lifeline communications in times of natural disaster.
Although updated standards that define capabilities beyond those defined in the current 4G standards are under consideration, those new capabilities are still being grouped under the current ITU-T 4G standards.
