After publicly saying that technology 5G DSS it cannot be considered as a fifth generation, the Minister of Communications, Fábio Faria, sent a letter to mobile operators requesting the removal of the 5G indicator icon when a smartphone is connected to a spectrum sharing network. The standard is defended by the GSMA, an association representing telecommunications providers.
O Teletime got the full letter from the minister sent to a mobile phone operator. In the document, Faria says that DSS technology is included in release 15 of 3GPP (entity responsible for creating standards for mobile networks based on GSM) and that it does not have the main benefits of 5G, especially in the Standalone format, which does not depend on an infrastructure Existing 4G.
The minister recognizes that the 5G DSS “represents an evolution to the fourth generation technology”, but that the fifth generation in Brazil must be based on 3GPP release 16 or higher, in order to guarantee the necessary requirements to enable reliable and low-cost applications. latency, massive Internet of Things and advanced mobile broadband.
In the letter, Faria argues that pure 5G will allow a “substantial improvement in the quality of mobile services” by allowing faster connections, with less latency and greater density of connected devices.
Minister asks for removal of the 5G icon on smartphones
The minister says that the current cell phone user “does not have access to this quality provided by the 5G technology provided for in the announcement, but has been surprised, on the screen of his phone or cell phone or tablet, with the indication that he is connected to a network type 5G ”.
In the letter, Faria asked operators to consider “reserving the expression 5G to refer exclusively to services that fall under 3GPP standard No. 16”. He says that the population is induced to conclude that 5G has already been implemented in Brazil, which has not brought a significant improvement in the quality of mobile services and makes the government’s effort to bid for frequencies “unjustified”.
The minister did not consider that the display of the 5G icon on smartphones is not an exclusive competence of cell phone operators: the icon is also implemented by the manufacturers of mobile devices, which use the nomenclature as a differential in the sale of products.
O Tecnoblog contacted Conexis to find out the position of the entity that represents the main operators, but did not receive a response until the publication of the article.
GSMA defends 5G DSS and claims that standard is also 5G
While the minister says that 5G DSS is not 5G, there are those who argue the opposite: the GSMA, a global association that brings together several operators and infrastructure providers for telecommunications, says that spectrum sharing technology is part of the fifth generation.
The entity also says that the DSS standard was defined in versions 15 and 16 of the 3GPP, and can be considered as the first step towards the deployment of 5G with dedicated frequencies.
In other countries, the 5G icon is displayed even when the smartphone is connected to a DSS network. Some devices show a different indicator when the device is in a coverage area with millimeter frequencies (mmWave).
Claro, TIM and Vivo use 5G DSS in Brazil
The 5G DSS is already a reality in Brazil, but only for those who have a compatible smartphone and are in the coverage area of the operators.
Despite having been sold, Oi Móvel also invests in 5G, but without spectrum sharing. The operator activated a network in Brasilia with a dedicated frequency of 2.1 GHz, and coverage reaches 80% of the federal capital.
