Some scientists are trying to stop the expansion of 5G cellular networks.
Boulder, Colorado – Some meteorologists are concerned that the expansion of the 5G cellular network could interfere with satellite observations and reduce the effectiveness of weather forecasts.
The Earth’s atmosphere naturally emits radio waves. Satellite sensors pick up these radio waves and convert them into meteorological data such as temperature and water vapor.
These radio waves are very weak and travel at very specific frequencies.
âAnd these frequencies, which are about half a dozen of them, are a gift of nature, and they’re the only ones that work that way,â meteorologist Bill Mahony said. National Center for Atmospheric Research (NCAR).
According to Mahony, 90% of the data entered into the computer prediction model comes from information about these radio waves.
The problem for meteorologists is that mobile operators want to buy these frequencies from the government.
According to Mahony, only certain frequencies are suitable for communication, and these frequencies are highly sought after because they can transmit data through the metal of a car or the walls of a house.
And they can support more users.
He said the government had already avoided certain frequencies that could affect the weather forecast, and they quickly expressed their willingness to sell more.
The only way for cellular carriers to expand their 5th generation cellular networks, known as 5G, is to add a wider frequency range.
The frequencies sold are in the 24GHz range.
This is very close to the 23.8 GHz signal emitted by water vapor. Mahony is concerned that 5G cell activity could bleed and disrupt weather satellites.
He said weather satellites could interpret cell activity as water vapor, rendering one of the most important elements of weather forecasting unusable.
âIf we lose or interfere with the data from these passive channels, we can take our weather forecasting skills back 30 years,â says Mahoney.
Mahony and other scientists testified in House committee meeting On July 20, we’ll try to stop the expansion, or at least delay it.
“I am optimistic that we will be able to protect these channels one day, and maybe we can implement a solution,” he said.
Mahony says he wants to successfully expand the 5G cellular network and wants more time to study the impact so the atmospheric science community can find alternative solutions.
“And we think the federal government should probably use some of the funding from these spectrum auctions to fund additional research,” he said. .. “To give you a better understanding of what the problem space really is.”
