Broadband Internet Access Basics - Data Validation

By CSC Staff

Contributor: Daryl Coffey

I spend countless hours determining how accurately each platform is represented on South Carolina’s state maps.  In South Carolina, I verify each of these platforms by going out into the field with tools, test equipment and data.  We refer to this process as “provider validation.”

Provider validation involves driving hundreds of miles following telephone and cable lines, or testing wireless signals in neighborhoods as well as in remote areas.  Naturally, when people see me holding up an antenna while typing on a computer in the back of an SUV, they’re curious about my intent.  When I inform them of what I am testing, folks are pleased that we are helping with broadband accessibility throughout the state. 

South Carolinians can always come away from our conversations with a better understanding of the broadband platforms and provider validation process.  Everyone I've talked to has been appreciative of the purpose of our work, and occasionally someone will say "well, thank you. We really need better Internet out here."
