5G Technology
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 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.
Were a 5G family of ITU standards to be implemented, it
would likely be around the year 2020, according to some sources.[1] A new
mobile generation has appeared every 10th year since the first 1G system (NMT)
was introduced in 1981, including the 2G (GSM) system that started to roll out
in 1992, 3G (W-CDMA/FOMA), which appeared in 2001, and "real" 4G
standards LTE-Advanced and WiMAX 2.0 fulfilling the IMT-Advanced requirements,
that were ratified in 2011 and products and services existing since
2012[citation needed]. Predecessor technologies have occurred on the market a
few years before the new mobile generation, for example the pre-3G system CdmaOne/IS95
in 1995, and the pre-4G systems Mobile WiMAX and first release-LTE in 2005 and
2009 respectively.
The development of the 2G (GSM) and 3G (IMT-2000 and UMTS)
standards took about 10 years from the official start of the R&D projects,
and development of 4G systems started in 2001 or 2002 However, still no
transnational 5G development projects have officially been launched, and some
industry representatives have expressed scepticism towards 5G.
