China has built giant radio antennas on land nearly five times New York, causing concern about military security and affecting people’s health.
The wireless electromagnetic method project (WEM) took 13 years to build. However, the researchers say that the system is ready to transmit extremely low-frequency radio waves or ELF waves. However, the World Health Organization warns that these waves can cause cancer with people living near the area.
Although the project has civilian applications such as those used to detect earthquakes and minerals, it may also play an essential role in military communications. Scientists say the transmission of the antenna can transmit signals to submarines operating hundreds of meters above the water surface without having to float to avoid the risk of being detected.
The project was built from China’s first military-grade super-low frequency superstation in 2009. A year later, China’s nuclear submarine successfully contacted the center from the waters. Deep. it is the third country in the world to establish such a submarine communication system, after the US and Russia. However, the Chinese navy still wants to expand its capacity and has poured resources into more advanced ELF radio technology, allowing submarines to communicate with the command center from a greater depth and difficulty in breaking down. Than.
The researchers said the antenna would emit an ELF signal with frequencies between 0.1 and 300 hertz.
The exact location of the facility has not been disclosed, but information from Chinese research journals indicates that it is located in the Huazhong area, an area in central China that includes Hubei and Henan provinces. And Hunan and are home to more than 230 million people.
