FCC bans U.S. sales of Huawei and ZTE equipment over national security concernsThe Federal Communications Commission on Friday announced it adopted new rules banning U.S. sales and imports of new Huawei and ZTE telecommunications devices out of national security concerns.Driving the news: "Today, the FCC takes an unprecedented step to safeguard our networks and strengthen America’s national security," Brendan Carr, the FCC's commissioner, tweeted on Friday.- Countries including Canada, Britain and Australia have ramped up restrictions against the use of 5G technologies from Huawei and ZTE in recent years.Flashback: The FCC was required to vote on the order within a year of the passage of the Secure Equipment Act, which President Biden signed into law on Nov. 11, 2021.- That law required the FCC to ban equipment sales by companies that pose an "unacceptable risk to the national security" of the U.S.- Carr in March 2021 called on the agency to close the so-called "Huawei loophole" which allowed companies to use private sector money to buy equipment from the firm because the FCC still authorized sales of its devices."
