Meteorologists Worry 5G Expansion Could Interfere With Weather Forecasts

Coverage Type: 

The Trump Administration’s swift-moving plan to promote 5G networks is running into resistance from the weather-forecasting community. The dispute centers around ultrahigh radio frequencies that the Federal Communications Commission recently auctioned off for use in the country’s next-generation wireless networks. Officials at other agencies, including the Department of Commerce and National Aeronautics and Space Administration, warn that those airwaves—specifically those above 24 gigahertz—could scramble nearby readings from the federal weather satellites that meteorologists use to make storm predictions. The concerns, for now, are theoretical, as cellphone carriers’ early upgrades have focused on other frequencies. But weather researchers worry interference could endanger future forecasts. Scientists warn the FCC’s plan “would substantially impact the accuracy of weather forecasts” used to gauge the risks from hurricanes, tornadoes and other severe weather, according to a recent letter Sens. Ron Wyden (D-OR) and Maria Cantwell (D-WA) wrote to FCC Chairman Ajit Pai.
