Well, the time we are living in is a time of evolution; at least in the world of technology and in the field of telecommunication the speed of advancement is a little quicker. There was a time just a year or so ago when the 3G technology was supposed to be the hot and happening achievement of technological persuasion but then, it became cold as soon as the new term 4G LTE surfaced at the horizon. Let us find out what exactly the 4G LTE is.
The term LTE stands for Long Term Evolution, it happens to be a wireless data communication standard that came out to light because of the Third Generation Partnership Project ie.3GPP. It has been designed to give the users ten times the speed of a 3G network for all the 4G enabled devices including mobile phones, tablets, ultraslim laptops, and wireless laptops. The 4G has been designed keeping an eye on the data communication at 1 Gbps.
There are several 4G standard and LTE happens to be one of them. Other standards are Ultra Mobile Broadband (UMB) and WiMax. All around the world the top guns of mobile service providing are battling hard to come up with the 4G technology; a few have been successful and others are trying their utmost to come up with the 4G. Verizon and AT&T have launched the 4G LTE whereas Sprint has come out with the latest 4G WiMax network. The highest download speed on 4G LTE is around 100Mbps and the Upload speed is 50Mbps.
Unlike the previous technologies where traditional data transfer is done, the 4G uses IP packet switched networks for the purpose. All the major carriers like the LTE standard because it supports bandwidth of 1.4 Mhz to 20 Mhz(which is quite flexible), Frequency Division Duplex and Time Division Duplex. That is not all, the standard has a provision for backward compatibility with older networks namely GSM, UMTS, and CDMA.
Though 4G is still a phenomenon that occurs in the developed nations but its rapid growth suggests that it will not take too long to hit the developing nations. It is here and it is here to stay.
