5G Does it affect weather information when it becomes practical?

On April 16, Apple and Qualcomm filed a lawsuit in connection with the intellectual property issue of the telecommunication semiconductor company and announced that they would withdraw all lawsuits. This may delay the procurement of 5G-related parts to be mounted on the iPhone, which could lead to the release of the 5G-capable iPhone,

On the other hand, to supply the 5G modem to the iPhone, Intel had to release a press release a few hours after the announcement of the agreement with Apple and Qualcomm to announce the withdrawal from the 5G modem market for smartphones. In any case, it is clear that the technology companies are moving in full swing over the next generation communication methods. If the 5G is put into practical use, it can affect weather information.

Every morning, as you can see through the TV, the Internet, and the smartphone app, you get all the weather information. Some of the weather data is obtained via meteorological satellites. Weather forecasts can be forecast tomorrow because meteorological satellites transmit terrestrial meteorological data from satellite orbits much higher than clouds to the ground.

The meteorological satellite observations data covers many aspects. For example, the surface temperature is measured by measuring the infrared rays emitted from the surface, and the movement of the clouds is observed with an optical sensor. Among the collected weather data, it is important to measure the distribution of water in the atmosphere by microwave. It is able to predict the cloud development by measuring the initial humidity by knowing the state of the water present in the atmosphere in water vapor state.

The highest frequency up to 4G communication was the 3.6GHz band. But in 5G, a new 24GHz or higher microwave is used. A high-performance micro-echo sounder equipped with AMSU (Advanced Microwave Sounding Unit Acquisition of Signal) for observation of water vapor in the meteorological satellite is the 23.6 ~ 24GHz microwave band which is most suitable for observing the water vapor.

Microwave using microwave oven of ultra-precise microwave radiometer of weather satellite is considerably close to microwave band to be used for 5G, so if 5G operation becomes full-scale, weather satellite sensor is likely to be affected.

Therefore, Commerce Commissioner Wilbur Ross and Director of the National Aeronautics and Space Administration, Jim Brideinstein, in the Federal Communications Commission (FCC), which oversees the frequency auction in the United States, However, the chairman of the FCC Aztite Pie rejected it and did an auction because it had no technical basis.

In fact, it is unclear whether 5G microwaves interfere with meteorological satellite observations. But there is an indication that no matter what happens, it can not be a plus in the weather. For more information, please click here .
