It is reported that the 5G auction in Brazil was originally scheduled to be held in March 2020 , but then the auction time was postponed due to some other tests. At this time, Ericsson took the initiative to reach out the olive branch. It is very likely that it wanted to participate in 5G construction in Brazil and win the country's 5G contract. However, some analysts pointed out that Ericsson's move is obviously "grabbing business", because Huawei has already occupied a certain advantage in the Brazilian 5G market.
