As cell carriers AT&T and Verizon planned to roll out nationwide 5G service this week, the FAA and U.S. DOT are asking the companies to pause their plans so more research can be done on the impact 5G has on aircraft technology. The companies are refusing, citing French regulations that limit wireless signals around airports while allowing research to continue. This week's launch wasn't the first time concerns have delayed 5G — last year, Airbus and Boeing express concerns, pushing the deadline into November, December, and then into this year. So what happens now — and what happens next? Will 5G roll out this year as expected? Jon Swartz, Senior Reporter at MarketWatch, joins Cheddar News' Closing Bell to discuss the state of the planned 5G rollout, why the FAA and U.S. Department of Transportation are asking carriers to stall the launch, and more.
