Researchers, including one of Indian origin, now say that upcoming 5G wireless networks that will provide faster cell phone service could result in inaccurate weather forecasts.

“Our study – the first of its kind to quantify the effect of 5G on weather forecast error – suggests that there is an impact on the accuracy of weather forecasts,” said lead author of the study. Narayan B Mandayam from Rutgers University in the United States.

According to the study, presented at the 2020 IEEE 5G World Forum, fifth generation (5G) cellular wireless technology stems from new, smarter ways to use higher frequencies (mmWave) for mobile communications.

This technology will revolutionize Internet communication and telecommunications. It offers faster connection times, increases the number of devices that can connect to a network and will be more widely available over the next two to three years, according to the researchers.

The Rutgers study used computer modeling to examine the impact of 5G “leaks” – the unintentional radiation from a transmitter in an adjacent frequency band or channel – on the prediction of the deadly Super Tuesday tornado outbreak of 2008 in the South and Midwest.

Signals from 5G frequency bands could potentially infiltrate the band used by satellite weather sensors that measure the amount of water vapor in the atmosphere and affect weather forecasts and forecasts.

Meteorologists rely on satellites to obtain the data necessary for weather forecasting.

Based on modeling, the 5G leakage power of -15 to -20 decibel watts (a decibel watt is a unit of power that describes the strength of radio waves) affected the accuracy of the precipitation forecast (up to 0.9 millimeters) during the tornado outbreak and near ground level temperatures (up to 2.34 degrees Fahrenheit).

“It can be argued that the magnitude of the error found in our study is insignificant or significant, depending on whether you represent the 5G community or the meteorological community, respectively,” Mandayam said.

“One of our takeaways is that if we want leakage to be at the levels preferred by the 5G community, we need to work on more detailed models as well as on antenna technology, dynamic reallocation of spectral resources and Improved weather forecasting algorithms that can take into account 5G leak, “he added.
