5G (5th generation mobile networks or 5th generation wireless systems)
is a name used in some research papers and projects to denote the next
major phase of mobile telecommunications standards beyond the 4G/IMT-Advanced
standards effective since 2011. At present, 5G is not a term officially
used for any particular specification or in any official document yet
made public by telecommunication companies or standardization bodies
such as 3GPP, WiMAX Forum, or ITU-R.
New standard releases beyond 4G are in progress by standardization
bodies, but are at this time not considered as new mobile generations
but under the 4G umbrella.
5G is sometimes used to refer to alternatives to these technologies based on the IEEE standards: mesh networks based on 802.11n protocol, IEEE 802.11u authentication and IEEE 802.21 handoff, the IEEE P1905 hybrid networking and the OpenFlow/OpenRadio methods of sharing backhaul (telecommunications). Almost all smartphones and tablets as of 2012 supported these standards, along with literally all notebook/laptops, and were able to prefer their (generally unmetered) use to 4G networks. However, to use these as a genuine replacement for 4G would typically require more coverage than is thought feasible outside large urban areas.
Imagine a speed of more than 1 Gbps in 5G
