Reviewing and Updating Regional And Local Broadband Mapping Act or the RURAL Broadband Mapping Act This bill requires the Federal Communications Commission (FCC) to temporarily accept broadband mapping data from a state to use in applications for funding with respect to the deployment of broadband internet access service in the state if the state data is superior to the data used by the FCC. This requirement applies until the FCC has completed certain broadband maps that are required under current law.
