5G arrives in Curitiba, Goiânia and Salvador this Tuesday (16)

Curitiba, Goiânia and Salvador begin to receive the 5G as of this Tuesday (16), according to a decision by Gaispi, a group that monitors the implementation of the technology in Brazil.

The providers that acquired the 3.5 GHz band in the 5G tender will be able to activate the stations with the fifth generation technology of the mobile service in the three capitals, which join Brasília (DF), Belo Horizonte (MG), João Pessoa ( PB), Porto Alegre (RS) and São Paulo (SP).

Tests to check for possible interference in the signals of Curitiba, Goiânia and Salvador were carried out last week, and Gaispi gave approval for the implementation of the technology in these municipalities last Friday (12).

At the beginning, it is worth mentioning that the signal only covers some neighborhoods of the cities, and it is still common that there are shadow areas, that is, where 5G does not catch on.

According to the Band Management Entity (EAF – Siga Antenado), the cities of Florianópolis (SC), Palmas (TO), Rio de Janeiro (RJ) and Vitória (ES) should be able to receive 5G by August 29th. .

The other 15 capitals will have the technology released until October 28. The initial implementation deadline was until the end of August, but Anatel postponed the implementation of 5G in these cities “based on logistical information”.

How does 5G work?

5G, or the fifth generation of mobile telephony, is the new network data transport technology involving mobile devices. It is the successor to the previous generations, 4G, 3G, 2G and 1G.

These technologies work through so-called “tracks”, which act as “avenues” for data transmission, only over the air. It is through them that the service will be provided. To CNN Brasil, technology specialist Arthur Igreja explained that 5G will allow new connections in an “exclusive” lane with more benefits.

“Imagine a lane of road with fast vehicles and vehicles together. She would be leveled down. Now, this ‘lane’ has been released for ultra-fast vehicles with pure 5G. We are talking about devices that should have different antennas, in addition to antennas installed in different parts of the city, paving these highways”, highlighted the specialist.

“Because of these facilities, 5G will take time to be implemented across the country. In the beginning, we are going to experience a lot the feeling of having to change lanes, as the user may be in a region of the city that does not have the antenna”, he added.

What changes?

In some regions of Brazil, 5G already shares the transmission range with 4G, but that makes it not full. This has changed since last month, when Brasília announced the implementation of “pure 5G”.

5G has significant differences from 4G and other earlier mobile internet technologies. Among the main ones are speed and low latency.

According to Eduardo Neger, president of the Brazilian Internet Association (Abranet), the faster connection allows for better resolution and quality of image and sound in videos.

In addition, the low latency is also a gain for users who want faster content and without having to deal with delays and sudden pauses during a program they are watching, for example.

“Latency is the delay in the response time of a device, application or website,” explained Neger. “When the network response is faster, you can do things like remote surgery or operate machines and autonomous vehicles,” he said.

According to experts, it will also be possible to improve services that benefit from the Internet of Things, from payment systems to enabling autonomous cars.

Other alternatives are solutions for public services, such as monitoring water consumption or lamp posts.

The speed and latency of 5G should still benefit activities such as telemedicine and agribusiness, with the improvement of real-time applications in these sectors.

“We have a number of real-time applications that cannot have this delay. In other words, imagine a doctor performing a surgery at a distance manipulating a robotic arm, he needs to have absolute precision, instant feedback”, highlighted technology specialist Arthur Igreja.

As for agribusiness, reducing the slowness between networks will allow for better remote operation of heavy machinery, with more support for the connection between devices.
