AT&T and Verizon say they will delay new 5G wireless service for two weeks, putting off a planned start this Wednesday. The company says it’s delaying the launch after a request from Transportation Secretary Pete Buttigieg and concern about possible interference with systems on board planes. AT&T and Verizon had planned to launch the new 5G service on Wednesday in many U.S. cities. Last week, a trade group for the airline industry asked the Federal Communications Commission to delay the so-called C-Band 5G service around airports.
