AT&T and Verizon are set to turn on their newest 5G technology Wednesday. Both companies purchased rights to more of the spectrum last year and have been ready to deploy it for months. But those plans have been on hold over concerns the expansion into that bandwidth could interfere with the tech on planes, specifically an aircraft’s altimeter, one of the tools that help planes land safely. To mitigate those concerns, the Federal Aviation Administration released a list of 50 airports that will have 5G buffer zones. Marketplace’s Kimberly Adams speaks with Joe Kane, director of broadband and spectrum policy at the Information Technology & Innovation Foundation.
