Scientists were able to communicate with hypersonic missiles via Wi-Fi: how did it work?

Researchers used 5G networks and were able to communicate with the rocket at frequencies of 5.2 – 5.8 GHz.

The South China Morning Post writes that researchers from Shanghai University (China) decided to use Wi-Fi bandwidth to communicate with hypersonic missiles.

A scientist named Jiao Tong has found a way to use 5G networks to communicate with hypersonic weapons. He and his assistants created an ultrathin antenna that they then placed at the back of the rocket body—where the body didn’t heat up. During ground testing, it turned out that the researchers found the antenna worked well in the 5.2 to 5.8 GHz range. These are low frequencies commonly used for 5G smartphones, high-speed Wi-Fi routers, and other wireless Internet-connected devices. The media emphasizes that the rocket referred to in the material flies at Mach 5, that is, 5 times faster than the speed of sound (6125 km / h). Metin emphasizes that “Hypersonic weapons developed by China can evade air defense systems by shooting down an aircraft carrier in motion from a distance of 1,500 km”.

However, establishing a connection was not easy, as lower frequencies created more noise on the missile surface, resulting in reduced signal strength and quality.

The team used a metamaterial added to the antenna as a membrane to capture electromagnetic waves. This helped lower the noise level, which was confirmed during testing.

The scientists want the antenna to “collect” low-frequency signals and create a single beam from them, so it can be oriented to cover the “blind area” in front of the rocket.

The results of the study were published in the January issue of the Journal of Microwaves, a peer-reviewed publication of the China Electronics Institute. However, the publication did not provide wind tunnel data or test flights, according to interestingengineering.com.

Earlier, we reported that an American engineer built a quadrocopter that could reach 400 km/h. The device was included in the Guinness Book of Records.
