DEFINITION AND DEVELOPMENT of 4G TECHNOLOGY

4G definition

4G networks (4G network) is a fourth-generation wireless networks for mobile communications.
This network is intended as a comprehensive network solutions and secure communications with data rates much faster than the previous generation.

New standards such as WiMAX and Long Term Evolution (LTE) has been referred to as 4G, although there are still some debate about their status.

4G specifications

4G networks specifically geared to provide high-quality services and high-speed data transfer as well.
This network is intended to provide better reception quality, more stable flow of data transfer, as well as the exchange of information faster.

International Telecommunication Union (ITU) or organization which oversees standards for wireless networks states that significant progress for multimedia messaging services, including video services, is a matter that must be achieved.

4G is able to deliver a minimum data transfer rate of 100 megabits per second when the user moves at high speed (such as when it was on the train), and at one gigabit per second in a stationary position.

Phones and mobile devices on 4G network also uses technology Internet Protocol (IP) to allow the transfer of data over a packet, instead of using a traditional phone.

 Advancement of 4G

One implementation of 4G networks are on WiMax technology, which is a faster version of wireless data transfer via WiFi networks.
LTE is another technology that is trying to get a 4G standard although not enough to meet the requirements of the ITU for the speed of data.

However, WiMax and LTE has been labeled as a 4G network, although admission is still trigger a bit of confusion and controversy.

Because both methods using IP packets and has shown progress compared to the 3G standard, ITU finally approved labeling them as 4G.

Early Before 4G Network

The first wireless network, known as 1G, launched in 1980.2G then introduced in the early 1990s that allows more transmissions per channel of communication.Furthermore, the foundation of 3G started in the late 1990s and began to be implemented in most of the world in the early 21st century.While the 3G network is the first to enable multimedia applications, 4G network promises to bring this basic technology to the next level.
