A study warns of 5G network interference with weather satellites


Researchers from the United States warned that signals from weather satellites could encounter interference, which leads to prediction errors, due to the use of 5G mobile phone networks of similar frequencies, as they modeled the effect of so-called “5G interference” on prediction of past weather events. .

According to the British newspaper “Daily Mail”, they found that interference from high-speed mobile phone networks could change the forecasts of precipitation by up to 0.9 mm and temperature by 2.34 degrees Fahrenheit.

“Our study is the first of its kind to determine the effect of the fifth generation on weather prediction error, and indicates that there is an effect on the accuracy of weather forecasts,” said the author of the paper, Narayan Mandayam from Rutgers University.

Professor Mandayam and colleagues modeled the network effect, a phenomenon in which emissions from a transmitter mistakenly encroach on adjacent frequency bands used for other purposes.

They simulated the effects of this leak on weather forecasting, and the researchers found that signals from the 5G frequency band have the ability to reach the adjacent bands that sensors on weather satellites use to measure the amount of water vapor in the atmosphere.

Meteorologists use this data to make weather forecasts, so the leak has the potential to upset their forecasts.

The team found that 15-20 decibel Watts leakage from 5G networks, a measure of the strength of radio waves, can change precipitation forecasts as well as temperatures.

“We need to work on more detailed models, in addition to antenna technology, dynamic reallocation of spectrum resources, and improved weather prediction algorithms,” the research team emphasized.
