The FCC has now granted Verizon, US Cellular, and T-Mobile permission to expand their 4G network capacity by temporarily using radio frequencies that are licensed to other companies, but had been sitting unused prior to the current pandemic. The unusual move by the FCC will help support the unprecedented number of people suddenly using wireless broadband to operate from home during the COVID-19 pandemic. T-Mobile was first to receive this special permission, and today announced that it has completed implementation, doubling the capacity of its 4G LTE network in band 71 (600 MHz). Yesterday, the FCC granted Verizon temporary use of idle spectrum in band 66 (also known as AWS-3). On Tuesday, the FCC granted similar permission to US Cellular.
