4K resolution is the high-definition goal that everyone is looking forward to. However, at this stage, 4K development is under heavy technical pressure, and one of them is the transmission method. Recently, Germany's wireless transmission technology has once again broken through its limits, and it can transmit data from one Blu-ray disc or five DVD discs in two seconds at an amazing speed.
100Gbps wireless transmission technology
The technology was jointly developed by the Fraunhofer Institute for Applied Solid Physics (IAF) and Karlsruhe Institute of Technology (KIT). This group of genius researchers broke a world record for wireless network transmission speed, and increased the wireless data transmission rate to an astonishing 100Gbps. The previous world record wireless transmission rate was 40Gbps, which was also created by the team.
However, this wireless transmission technology also has many shortcomings. First, the frequency it uses is as high as 237.5GHz, resulting in a short transmission distance, only 20 meters in the laboratory, and secondly, this technology has very poor penetration and cannot pass through the wall.
This experiment is of great significance. It can be said that the promotion of 4K will be seen in the cloud, and it is also expected to improve the wireless network coverage in the suburbs. But for most netizens, the most incredible thing is that the budget of this magical team to complete the entire project is only 2 million euros, which really makes many domestic experts feel uncomfortable.
