Currently 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 <a href="http://en.wikipedia.org/wiki/3GPP" target="_blank">3GPP</a>, <a href="http://en.wikipedia.org/wiki/WiMAX" target="_blank">WiMAX</a> Forum or <a href="http://en.wikipedia.org/wiki/ITU-R" target="_blank">ITU-R</a>. New <a href="http://en.wikipedia.org/wiki/3GPP" target="_blank">3GPP</a> standard releases beyond 4G and <a href="http://en.wikipedia.org/wiki/LTE_Advanced" target="_blank">LTE Advanced</a> are in progress, but not considered as new mobile generations.The implementation of standards under a 5G umbrella would likely be around the year of 2020<a href="http://en.wikipedia.org/wiki/5G#cite_note-Li-0" target="_blank">[1]</a>. A new mobile generation has appeared every 10th year since the first <a href="http://en.wikipedia.org/wiki/1G" target="_blank">1G</a> system (<a href="http://en.wikipedia.org/wiki/Nordic_Mobile_Telephone" target="_blank">NMT</a>) was introduced in 1981, including the 2G (<a href="http://en.wikipedia.org/wiki/GSM" target="_blank">GSM</a>) system that started to roll out in 1992, and 3G (<a href="http://en.wikipedia.org/wiki/W-CDMA" target="_blank">W-CDMA</a>/<a href="http://en.wikipedia.org/wiki/FOMA" target="_blank">FOMA</a>) which appeared in 2001. The development of the <a href="http://en.wikipedia.org/wiki/2G" target="_blank">2G</a> (<a href="http://en.wikipedia.org/wiki/GSM" target="_blank">GSM</a>) and <a href="http://en.wikipedia.org/wiki/3G" target="_blank">3G</a> (IMT-2000 and UMTS) standards took about 10 years from the official start of the <a href="http://en.wikipedia.org/wiki/Research_and_development" target="_blank">R&D</a> projects, and development of 4G systems started in 2001 or 2002.<a href="http://en.wikipedia.org/wiki/5G#cite_note-Akhtar-1" target="_blank">[2]</a><a href="http://en.wikipedia.org/wiki/5G#cite_note-2" target="_blank">[3]</a>. It is expected that in terms of data streams, a 5G standard would have peak download and upload speeds of more than 1 <a href="http://en.wikipedia.org/wiki/Gbps#Gigabit_per_second" target="_blank">Gbps</a>.<a href="http://en.wikipedia.org/wiki/5G#cite_note-Akhtar-1" target="_blank">[2]</a> The development of the bit rates offered by cellular systems is however hard to predict, since the historical bit rate development have shown very little resemblance with a simple exponential function of time (as opposed to for example <a href="http://en.wikipedia.org/wiki/Moore%27s_law" target="_blank">Moore's law</a> for computing capacity). The data rate increased by a factor 8 from 1G (NMT 1.2 <a href="http://en.wikipedia.org/wiki/Kbps" target="_blank">kbps</a>) to 2G (GSM 9.6 kbps). The peak bit rate increased by a factor 40 from 2G to 3G for mobile users (384 kbps), and by a factor and 200 from 2G to 3G for stationary users (2 <a href="http://en.wikipedia.org/wiki/Mbps" target="_blank">Mbps</a>). The peak bit rates are expected to increase by a factor 260 from 3G to 4G for mobile users (100 Mbps) and by a factor 500 from 3G to 4G for stationary users (1 Gbps).<a href="http://en.wikipedia.org/wiki/5G#cite_note-3" target="_blank">[4]</a></blockquote>
