Mobile network technology in Indonesia is now entering the era of 4G, but not a few cellular technology is still using the 3G network and even 2G. This network is always experiencing the development from time to time and will always be developed in line with the increasing sophistication of cellular technology in all parts of the world. Every era of this development has a significant difference from the 1G network that is now no longer used up to the $ G technology that is now being implemented around the world as the latest network technology.Differences in Cellular Network Technology From Time to Time1G technology is the first mobile network technology known by the world with analog signals. This 1G technology evolved in the 70s and 80s, but unlike today's technology networks, because this network technology can only be used to communicate by voice only or is limited to telephone services and accompanied by the use of mobile phones at the time.Slightly more advanced in the era of 2G mobile network technology that was introduced in the 90s, the network technology that originally used analog signals developed into digital signals as the development of technology and the increasing number of mobile phone users around the world. Especially in this era of SMS or short message and picture messages began to be introduced. Not only that on 2G technology is also supported with a better voice service technology and accompanied by data access support known as 2G EDGE network that has data access speeds up to 1 Mbps.And in 1998 the third 3G network technology began to be introduced. This network technology has been quite perfect article besides the users can use the phone service, short messages and picture messages can also access the Internet network with a faster connection without using a data cable. this network technology is an early technology of mobile broadband that supports the transfer of audio, images and video that allows its users to stream or video call.And the last is the latest 4G technology known as 4G LTE network. Until now 4G LTE technology is claimed to be the fastest network technology with download speeds of up to 100 Mbps and upload speeds of up to 50 Mbps. But this speed is not considered maximal, because for the standard 4G hharus supported with download speeds up to 500 Mbps. So it still needs to be refined to achieve maximum capacity. Meanwhile in Indonesia, this network technology has been used by some of the leading mobile operators although the technology is still very limited. Thus information related to the development of cellular network technology that we can convey, may be useful ..Description: Mobile network technology until now has experienced 4 times change namely 1G, 2G, 3G and the latest network is currently 4G LTE network.
