4G network is the latest wireless mobile communication which is the fourth generation of computer network.
The main purpose for the network is to provide an extensive and secure network communication and providing solution to problems with much faster data speeds than previous generations. While still in development, the bases for upgrading from 3G to 4G service started in the early 21st Century as companies began to introduce new technology. New standards such as WiMax and Long Term Evolution (LTE) have been referred to as 4G, though there are argument about their capacity.
The first wireless network, which is known as 1G, was founded during the 1980s. Were by the introducing of 2G in the early 1990s allow more transmissions to occur per communication channel.
The foundations of 3G were established in the late 1990s and were carry out throughout the best part of the world in the early 21st century. The 3G network was the first to allow multimedia applications, the 4G network also promises to take this fundamental technology and boost it significantly.
The fine point of the 4G network are geared toward high-quality service and fast data transfer rates.
The Priorities for this standard include better reception, with less dropped data, and faster information exchanges. The International Telecommunications Union (ITU), the organization that oversees standards for wireless networks, has stated that significant improvements to multimedia messaging services,
including video services, are required for the approval of a new generation. 4G requires a data speed transfer rate of at least 100 megabits per second while a user moves at high speeds, such as being on a train, and a one gigabit per second data rate in a fixed position. The ITU also requires fast transfers between networks without service interruption or loss of signal. Phones on a 4G network also need to use Internet Protocol (IP) technology for data transfers through packets, rather than the common phone methods.
Different types of working group have been fixed to help develop the 4G network. Early developments toward this technology include WiMax, which is a faster version of wireless data transfer than WiFi networks. LTE is another technology that improves upon older 3G systems, but non of the standard have fulfills the ITU requirements for data rates. Both of them have been labeled as 4G networks, however leading to confusion and controversy. As both methods utilize IP packets, and have shown a marked improvement over 3G standards, the ITU has specify it as 4G. This is fluky upon the developers of WiMax and LTE pushing forward to meet the official standards for 4G, which they have continued to do.
The general applications of the 3G network around the world took nearly a decade. The ITU plans to have the 4G network rolled out to the global market in a much more effective and timely manner. The improvement made between 2G and 3G required substantial advancement in hardware for mobile devices, while companies developed many smart phones used on 3G networks for compatibility with
new 4G standards. However, concerns over stability and security have slowed down some improvements, as service providers want to ensure they protect their customers’ information very well.
