WASHINGTON (Reuters) - The Federal Aviation Administration (FAA) has raised significant concerns about a plan to use spectrum for 5G wireless networks on aviation safety and is planning to issue a formal warning about the issue, according to sources and a letter seen by Reuters.

The aviation industry has voiced alarm about the plan to use C-Band spectrum for more than a year. Network carriers are expected to begin using the spectrum starting Dec. 5 starting in 46 markets.
