What is 5G? understand the technology

Successor to 4G technology, 5G should arrive in Brazil in 2021. See how it can change the telecommunications sector.tracktracktracktracktrack


From dial-up internet dinosaurs to ever-faster smartphones, the evolution of technology is as fast as a meteor. After 3G and 4G, the natural evolution now takes us to the famous 5G.The new technology has been the subject of recent months, and should offer more internet connection speed on cell phones. This makes it possible from connecting many devices to the internet at the same time to driving autonomous cars, which do not require drivers.

The network is already a reality in some countries, such as Germany, China, the United States and Japan. In Brazil, the implementation is still in its initial phase.

But do you know what 5G technology is? How long will it take for Brazilians to have access to it? Is it better than 4G? Below, learn more about the subject.


First, what are the Gs in this technology?

If you thought it must be the letter for a difficult word, this time you didn’t get it right. In fact, the G of 3G, 4G and 5G stands for “generation”. As primates advance through history, each evolution in network performance or capacity is called a “new generation”.

With 3G, for example, it was possible to send messages using the internet via cell phones. 4G made it possible to download streaming services and watch video from anywhere there was a signal.

With 5G, it will be possible to have more internet speed and connect many objects to the network at the same time. Wait a minute… objects? That’s right: watches, drones, pet collars, and even cars that run alone, without a driver. Welcome to the Internet of Things (IoT) era .


How does 5G work?

5G networks work over radio waves – just like previous generations. However, the fifth generation of mobile broadband is significantly larger.

While the average speed of 4G in Brazil is 19.8 Mbps (megabits per second), 5G can reach up to 10 Gbps (gigabits per second). That’s 100 times faster than 4G.

The 5G network antennas will be coupled to those that already exist. The 4G antennas, in turn, must be adapted to work in parallel with the new connection infrastructure while the two systems coexist.

It will be necessary to install ten times more antennas, on poles or in tall buildings, to replicate the 5G signal, according to the Telecommunications Secretariat. When installed, they will be able to cover distances of up to 250 meters in radius, and will require a renewal of the fiber optic network.


What changes with 5G?

Improvements in connection, speed and response time should facilitate the use of technologies in autonomous cars, telemedicine, automated production lines in industries… there are many possibilities that unfold with the 5G network.

So-called autonomous cars already exist, but the response time of the 4G network is still not fast enough to avoid accidents in extreme situations, nor does it support so many devices connected at the same time.

Teleconferences will have a better connection, the online gaming experience should also be improved, and live video streams should crash less.


How much will 5G cost? What influences my plan?

Operators generally do not offer exclusive access to one type of network technology, but charge for the data allowance used.

Mobile phone companies, however, have not yet defined whether there will be adjustments in the prices of data packages, as it will take a few months until the technology is available.

Access to 5G should be restricted at first for two reasons: less coverage, primarily centered on capitals; and the compatibility of few cell phones, which are currently the most expensive on the market.

What is the 5G auction?

In Brazil, the 5G is in the phase that precedes the auction of frequencies , the first step towards the implementation of the technology in the country.

The rules of the notice (with requirements, goals and counterparts for those who buy the tracks) were approved by Anatel and will still pass through the Federal Court of Accounts (TCU). The federal government expects the auction to take place in the first half of 2021.


What are 5G ranges?

The 5G bands are the frequencies on which the network operates. And that is what will be auctioned by the Brazilian government, allowing operators to start offering the fastest connection to their customers.
