Connect America Fund; Universal Service Reform-Mobility Fund

In this document, the Rural Broadband Auctions Task Force (Task Force), with the Wireline Competition Bureau and the Wireless Telecommunications Bureau (the Bureaus), propose and seek comment on specific parameters and procedures to implement the Mobility Fund Phase II (MF-II) challenge process. This document describes the steps the Federal Communications Commission (Commission) intends to use to establish a map of areas presumptively eligible for MF-II support from the newly collected, standardized 4G Long Term Evolution (LTE) coverage data and proposes specific parameters for the data that challengers and respondents will submit as part of the challenge process, as well as a process for validating challenges.
