A study by Rutgers University researchers found upcoming 5G wireless networks that expedite cellphone service may lead to inaccurate weather forecasts.

Signals from 5G frequency bands could leak into the band used by weather sensors on satellites that quantify atmospheric water vapor.

The Rutgers team used computer modeling to examine the impact of unintended 5G leakage into an adjacent frequency band in predicting the 2008 Super Tuesday Tornado Outbreak in the South and Midwestern regions of the U.S.

The modeling found 5G leakage of -15 to -20 decibel Watts impacted the accuracy of rainfall forecasting by up to 0.9 millimeters during the tornado outbreak, and also affected forecasting of temperatures near ground level by up to 2.34 degrees Fahrenheit.

Rutgers' Narayan B. Mandayam said, "If we want leakage to be at levels preferred by the 5G community, we need to work on more detailed models as well as antenna technology, dynamic reallocation of spectrum resources, and improved weather forecasting algorithms that can take into account 5G leakage."
