At the World Radiocommunications Conference in Egypt, meteorologists called for stricter restrictions on the frequency of radio frequencies used by 5G wireless carriers,media The Verge reported. Delegates voted On Friday to pass a new international standard that sets looser limits on interference in 5G’s operations in specific bands, which are essential for accurate weather forecasting. Meteorologists fear the decision could one day seriously affect its ability to forecast strong storms, leaving communities around the world vulnerable to extreme weather events.
Friday’s decision is the culmination of a month-long battle between scientists and 5G supporters over the precious 24GHz radio band. Telcos need to take up higher bands, including those, to achieve the faster speeds that 5G should provide. But by expanding the scope of influence, they conflict with the frequency bands that scientists use to study water vapor. Forecasters say that if 5G wireless carriers use the band, there’s nothing they can do because the water vapor molecules they track will naturally send a faint radio signal around 24GHz.
After Friday’s Decision in Egypt, Eric Allaix, chairman of the World Meteorological Organization’s Radio Frequency Coordination Steering Group, told The Verge that they would have “no solution.” Although 5G construction is still under way, Alex says that once it replaces the current band, “then we will not be able to distinguish between observations of radiation from the Earth and the atmosphere and interference from 5G.” “
The United Nations International Telecommunication Union convenes the World Radiocommunication Conference every three to four years to discuss new radio frequency regulations for controversial frequency bands such as 24GHz. Their work is particularly tricky because the radio frequency is cluttered and there are many different technologies and natural phenomena running in a very crowded space on the spectrum. To maintain order, the meeting attempts to create a buffer between groups that use similar bands to avoid conflicts. These buffers are called out-of-band radiation limits. They are measured in a dBW unit that tells people the strength of the signal that deviates from its boundary. Strict interference limits leave a larger gap between frequencies.
Friday’s meeting set a limit on 5G technology emitting noise up to -33 dBW outside the 24GHz band. This is not as strict as the WMO is trying to allow -42 dBW. The weather community did get a bit of a concession: eight years from now, the limit would be tightened to -39 dBW.
“These values are considered sufficient to protect the meteorological satellite system and are therefore considered sufficient,” David Bottas, a consultant to a research group at the International Telecommunication Union, said at a press conference today. Nevertheless, we note that there are concerns. He added that the impact of 5G will be monitored as the system is deployed.
The new restrictions remain stricter than the 20 dBW limit proposed by the Federal Communications Commission in March. The FCC auctioned its license for the 24GHz band in March as part of its mission to make the United States a global leader in 5G technology.
“The Trump administration has called for us to stand on the same page as China and our competitors,” Brad Gillen, executive vice president of CTIA, a wireless trade group, said in a statement. We can and will have 5G and weather forecasts. “
But the study by NASA and the National Oceanic and Atmospheric Administration found that the limit should actually be kept as close as possible to -52.4 DBW as possible to prevent 5G interference from satellites used to collect meteorological data. “This part of the electromagnetic spectrum is necessary to predict where the hurricane will land,” NASA Administrator Jim Bridenstein told Congress in April. If you can’t make that prediction accurately, you’ll eventually be unable to evacuate the right people or those who don’t need to be evacuated, which is a problem. “
