What is 4G?

Understand what has changed in the 4th generation of mobile technology, how it works and its application in Brazil for the 2014 World Cup and the 2016 Olympics.

The mobile phone and internet system has been evolving rapidly, it would be good if its application were also as fast as the evolution, because in several regions of the country the 3rd generation is still unknown. With the new technology 4G, watching videos and TV shows on your smartphone while you’re walking the streets will not be a problem, not to mention the possibility of streaming and video calls in real time with your friends without having the connection problems constant of the traditional mobile internet that we have.

What is 4G?

4G is the acronym that defines the fourth generation of mobile technology, successor of the second and third generation, it works with LTE (Long Term Evolution) technology – which is a data transmission technology based on WCDMA and GSM technology, but already that currently data transmission is far more common than voice transmission, 4G technology from the priority to internet data, but of course, does not rule out the idea that we can still make voice calls.

LTE technology is not the only one that can be considered as a 4G technology, we also have the WiMAX, which was created by a group of industries known as WiMAX Forum whose goal is to promote compatibility and interoperability (works on Linux systems) between equipment based on the IEEE 802.16 standard.However, WiMAX is much less common than LTE, which will be deployed here in Brazil. Soon we will do a matter specifying what is WiMAX.

What is 4G

What has improved?

As a priority for data traffic, the network would certainly be faster and more stable, even when the LTE was created, there was at least no possibility of voice traffic, which would oblige carriers to adapt it to this.

In tests conducted by researchers, LTE technology reached a data transfer rate of 20 MHz from 300 Mbps downstream and 75 Mbps upstream, of course, the tests were performed in the laboratory, which maximizes its power, the actual speed of navigation is around 100 Mbps of download and 50 Mbps of upload and a latency (PING) of maximum 30 ms (milliseconds).

In addition to being cheaper, faster and with much more structured coverage, 700MHz LTE technology can support 300 to 400 simultaneous accesses to the data traffic network, which is almost double the amount 3G technologies support.
