AT&T (NYSE:T) and Verizon (NYSE:VZ) stocks slipped on Thursday after The Wall Street Journal reported that the cellphone carriers agreed to delay their planned rollout of a new 5G frequency band.Their planned 5G deployments will be delayed until 5 January to address concerns about potential interference with key cockpit safety systems.Verizon traded 2.1% lower, and AT&T fell 1.5 %, while broader U.S. stock indexes were mixed.The FAA, a unit of the U.S. Transportation Department had been planning to issue official mandates that would limit pilots’ use of certain automated cockpit systems to avoid potential interference from wireless towers on the ground transmitting new 5G signals.Interference between spectrum bands used by different end-users for their services has been a long-standing issue, especially between telecom service providers and airlines.These limits could disrupt passenger and cargo flights in 46 of the country’s largest metropolitan areas where towers are situated.Telecom industry officials disputed claims that the proposed cellular signals would represent any dangers, saying that available evidence doesn’t support the conclusion that the proposed 5G signals will interfere with flight equipment.
