Three national groups combine their resources to create a new app to measure broadband speeds around the country. All they need now is you and your smart phone.The National Broadband Map has been decommissioned. The latest report from the Federal Communication Commission (FCC) has serious flaws, researchers say. And private efforts to measure access speeds tend to underrepresent rural areas and cause confusion about what speed is available and what consumers actually pay for. A collaboration of three national rural nonprofits hopes to create a more accurate picture for researchers and advocates to use to see how their communities measure up. The TestIT smartphone app invites rural residents to participate in the effort, identifying current broadband speed and service gaps in underserved communities.
