There are many changes in the world of communication. Landline phones are not much used today. All most all people throughout the world possess mobile phones. 5G (5th Generation mobile networks or 5th Generation wireless systems) designates the next major phase of mobile telecommunications standards superior to the current 4G standards. 5G is also referred to as future (ahead of 2020) mobile communications technology. Presently, 5G is not a term that is used for any particular specification or in any official document, but yet made public by telecommunication companies and standardization bodies such as 3GPP, WiMAX forum or ITU-R.
