As a result of the shutdown, a majority of the agency's employees will be furloughed, with fewer than 20 percent who will continue working. FCC Chairman Ajit Pai and the three commissioners -- Michael O'Rielly, Brendan Carr and the lone Democrat on the commission, Jessica Rosenworcel -- will continue to work.

One thing not affected by the shutdown will be the agency's first 5G wireless spectrum auction, which is auctioning off licenses in the 28 gigahertz and 24 GHz spectrum bands, according to the FCC. The auction will resume as scheduled on Thursday. The auction, which began in November, was paused during the holiday break and is expected to continue for the foreseeable future, but will likely wrap up soon.
