4G or fourth generation technology is a mobile communications technology that will soon compete with 3G technology which is currently being rapidly adopted. Characteristic of 4G technology is all IP-based network that already. 4G technology also has the characteristic that this phone will still function properly when used in vehicles with a speed of 150 km / h with transfer speeds reaching 54Mbps. From the article "Getting the Pre-4G technology after 3G technologies," we can see that when the 4G technology has been implemented, based on 3G phones will lose its popularity and was replaced by laptops equipped with wi-fi and softphone, as well as by the PDA wi-fi equipped, which can be used as a Pre-4G phones, as well as other devices that supports Push-To-Talk and SIP can also be used for communicating with pre-4G technologies.
Some companies have already started doing this 4G technology development. Such as Huawei, Intel, Vmax, LG, and other companies. In the article "Huawei's LTE Network Restore TeliaSonera", Huawei is trusted by the leader of telecom operator in Scandinavia and the Baltic states to provide 4G/LTE first commercial network in the world. Huawei will provide solutions to end-to-date LTE eco-friendly and provides services such as network design, implementation, system integration and support systems. Intel also start the movement by investing millions of dollars to develop 4G technology in Taiwan that will be tilled by the carrier Vmax, as reported in the article "The Intel investment 11.5 jt For Taiwan 4G." LG also plans to produce mobile LTE in 2010. In the article "LG Develops Chip 4G" explained that LG Electronics Inc. has developed a modern chip technology based on 3GPP Long Term Evolution (LTE) or the so-called 4G, is expected to encourage the creation of phones that have high speed internet access. But in the article "Not Ready to Live Operator LTE World", an analysis from ABI Research said that most operators in the world most likely not ready to move to LTE because of the speed of downlink and uplink, each of which reaches 100 Mbps and 50 Mbps, can only be made in the network frequency 20 MHz, while the frequency is also a 'luxury' that is not owned most of the operators in the world.
Of these articles, it can be concluded that the 4G technology is expected to increase the speed of mobile internet access, until now still in the stage of development. The companies had started their movement in various ways to realize this 4G technology. Although not all parties are optimistic with the development of this technology, 4G will still continue to be developed to meet the needs of operators and users who want more speed, and efisienisme and higher effectiveness.
