Earlier this week there was a brief kerfuffle over whether the American government should pay to build the next generation of wireless, known as 5G, so that China doesn’t beat us to the punch.

And is public worry about cell towers holding up the deployment? Marketplace Tech host Molly Wood talks with Sundeep Rangan, director of the research center NYU Wireless and a professor of electrical engineering.
