One way the FCC may be able to do this is by allowing the use of data from consumer initiated speed tests, including commercial data sets that take advantage of such data, to help supplement Form 477 data. Further, the FCC could look to incorporate the data from states like many of ours who have begun to take mapping into their own hands using voluntary public speed tests, drive tests and GIS software to create their own maps on a more localized and granular level. While we are glad the FCC is trying to address some of the issues with their mapping though the ongoing Form 477 proceeding, this alone will not solve everything. As long as we continue to rely solely on carrier-reported Form 477 data, we will never have a complete picture that accurately depicts the real world experiences of Americans. That is the lesson we should learn from the Challenge Process. We are not suggesting that crowdsourced data is perfect and that it alone will be enough to fix the greater challenges with broadband mapping, but it is an important tool we should have in the toolbox. We believe the creation of a public feedback mechanism is feasible and would be a critical first step toward creating more reliable and accurate broadband maps. Therefore, we respectfully ask for a formal and prompt response to the following questions and would welcome the opportunity to meet with you or your staff to discuss them further: " Do you see validity in using a continuous public feedback mechanism to help improve broadband coverage maps and data? " Do you think it is feasible for the FCC to implement a public feedback mechanism to help validate Form 477 data? o If so, what would that process look like? o If not, what specifically can the FCC use to help supplement Form 477 data in detennining where there is broadband coverage in the United States? We look forward to your response and continuing our work together to close the digital divide.
