A new wireless LAN technology has been developed by scientists at the karsruer Institute of Technology in Germany, breaking the WiFi network data transmission speed record, allowing users 1 km away to download data at a speed of 40 Gb per second, this is equivalent to 10 HD movies with a length of 2 hours.

The rapid advances in the transmission speed of wifi not only benefit from cutting-edge hardware devices developed by scientists at the karsruer Polytechnic Institute, but also because they use a much higher frequency than normal WiFi-240 GHz. The hardware they developed is a set of chips that can process signals at a higher frequency.

The higher the frequency, the smaller the size, because smaller antennas can receive shorter signals. Because of this, FM and am broadcasts require relatively larger antennas, while WIFI networks can use smaller antennas. Therefore, the chip diameter developed by scientists at the calsruer Institute of Technology is only a few millimeters.

High frequency is essential for the transmission of large amounts of data-the amount of data transmitted by radio waves, which is inversely proportional to the wavelength. The shorter the wavelength, the more data is transmitted within a specific period of time. The frequency of a common Wi-Fi network is generally 2-4 GHz or 5 GHz. The transmission speed of dozens of megabytes per second is also very common.
