What is a 4G network?

4G network is the fourth generation of wireless mobile communication. The overall goal for the network is to provide a comprehensive and secure solution of network communication with much faster data speeds than previous generations. While they are still developing, the upgrade Foundations from 3G to 4G services began at the beginning of the 21st century when companies began to introduce new technology. New standards such as Wimax and long -term development (LTE) have been referred to as 4G, although there is some debate on their condition.

4G Specification

4G network specifics are focused on high quality services and fast data transfer. Priorities for this standard include better reception, with less dropped data and faster information exchange. The International Telecommunications Union (ITU), an organization that oversees wireless networks standards, said that significant improvements in multimedia reports, including video services, are obliged to approve a new generation.

4G requires a speed transfer speed of at least 100 megabits fromAnd a second while the user moves at high speeds like being on the train, and one gigabit per second at a data speed in a fixed position. ITU also requires quick transfers between networks without interrupting the service or losing signal. The 4G network phones must also use Internet protocol technology (IP) for data transmission via packets, rather than traditional telephone methods.

Progress towards 4G

A number of working groups have been set up to help develop a 4G network. The first development towards this technology includes Wimax, a faster version of wireless data transfer than WiFi® networks. LTE is another technology that improves on older 3G systems, but even the standard does not fully meet the requirements of ITU data speed.

Both of them, however, marked 4G networks, which led to some confusion and controversy. Since both methods use IP packets and have shown a significant improvementCompared to 3G standards, ITU approved its labeling as 4G. This depends on Wimax and LTE developers that push forward to meet the official 4G standards, which they continue to do.

Upgrade from 3G to 4G

The overall implementation of 3G network worldwide took almost ten years. ITU plans to bring the 4G network to the global market much more efficient and timely. Improvements between 2G and 3G required significant improvements to hardware for mobile devices, while companies have developed many smartphones used on 3G networks for compatibility with new 4G standards. However, concerns about stability and security have slowed down a certain development because service providers want to ensure that they protect their customers' information.

early network before 4G

The first wireless network, known as 1G, was founded in the age of 80. 2G was introduced at the beginning of the 90s to allow further transmissions to the communication channel. Foundations of 3g were founded at the end of the 90's years and were introduced throughout the whole inthe world at the beginning of the 21st century. While the 3G network was the first to allow multimedia applications, the 4G network promises this basic technology and significantly intensifies it.
