5G is coming to Brazil. Despite the auction by the National Telecommunications Agency (Anatel) having been postponed to 2021, three operators already offer the service in 11 Brazilian cities, thus testing the operation of the technology that is already the target of an intense worldwide dispute and should have a decisive impact on fields such as speed and higher rate of data transmission, in addition to decisively inaugurating the so-called internet of things (IoT), integrating thousands of devices with equipment, furniture and appliances.
Apart from the political dispute that involves the arrival of this new technology, certifiers and laboratories are already working on training their technical parks in order to assess the main parameters of 5G technology. This implies verifying the electromagnetic compatibility of the new standard, as well as its safety for the user and its characteristics in the radio frequency emission that can be absorbed by the human body. Quiet work, but essential for the new data platform to operate effectively and safely for its users.
“This work is important and necessary to offer security to the user who is going to use the device and also to protect the spectrum. It is necessary to ensure that the telecommunications product under analysis is operating in the correct frequency range and that the device does not cause or suffer interference in the environment that is used ”, explains Fabio Jacon, vice president of Telecommunications at the Brazilian Conformity Assessment Association ( Abrac), an entity that brings together certification and inspection companies in Brazil.
Jacon also points out that the certification and testing process for each product that enters the market “takes from one to two months between the tests, the analysis of the organism and the final evaluation by Anatel”.
To assess 5G technology in Brazil, criteria were defined based on international references from the 3GPP (3rd Generation Partnership Project), which standardizes, with the support of the international industry, new technologies, and thus the service is the same in all countries, only with the difference in the frequencies available in each territory.
The evaluation tests of the fifth generation mobile network include technology analysis, Electromagnetic Compatibility Tests (EMC), electrical device safety and SAR (Specific Absorption Rate) evaluation.
Is 5G already in Brazil?
In June 2020, Anatel established the testing requirements applicable to both base stations, which will provide 5G technology in the networks of telecommunications operators, and to mobile terminals, which will allow users access to the technology. Initially, the mobile operators present in Brazil will share the frequencies that are already allocated for the operation of the current cellular technology, through a technique called DSS (Dynamic Spectrum Sharing).
Following the rules determined by Anatel, when launching a new product in Brazil, the local manufacturer selects a Designated Certification Body (OCD) and provides the technical information about the product, which is analyzed in order to determine the applicable standards and tests.
Then, the laboratory that will perform the tests is chosen, which performs the tests and issues its report. This is analyzed by the Certifier, which, in case of positive results, registers the product with Anatel, which analyzes the documentation and issues the homologation certificate for the product or service to be marketed.
