The experiment was conducted by 25 institutes of the Second Academy of Aerospace Science and Technology of China (CASC). The team used a high-precision spiral phase plate antenna to achieve four different beam modes in the 110GHz frequency band. Through the synthesis of four modes, they completed 100Gbps wireless real-time transmission on the transmission bandwidth of 10GHz, which maximized the bandwidth utilization rate.
Terahertz communication is a new spectrum technology that can provide greater transmission bandwidth to meet the transmission needs of higher rates. It has gradually become one of the key technologies of 6G communication.
With the continuous improvement of communication rate requirements, the mobile communication frequency band has been expanded to millimeter waves and higher terahertz frequency bands. This is also the main research direction of the global 6G network.
In the classification of electromagnetic waves, terahertz waves are located between “electric waves” such as microwaves and millimeter waves and “light” such as visible light. Usually, its frequency range is 100GHz-10THz (terahertz) and the wavelength range is about 3mm-30μm, which refers to the area where radio waves and light overlap.
The successful completion of this experiment is a major breakthrough in China’s 6G communication technology research and development. It provides important guarantee and support for the technical development of China’s 6G communication technology.
In the future, terahertz communication technology has the potential to be applied in a wide range of fields, such as high-speed broadband transmission, high-definition video transmission, and virtual reality. It is also expected to play an important role in China’s deep space exploration and the development of new spacecraft.
Terahertz Communication Technology
Terahertz communication is a new spectrum technology that operates in the terahertz frequency band (THz band). The THz band is located between microwaves and infrared radiation. It has a wide bandwidth and can be used for high-speed data transmission.
Terahertz communication has several advantages over traditional communication technologies. It has a high transmission bandwidth, which can support high-speed data transmission. It is also a short-range communication technology, which makes it ideal for applications such as indoor communication and vehicular communication.
The Future of 6G Communication Technology
6G communication is the next generation of mobile communication technology. It is expected to offer peak data rates of up to 1Tbps. Terahertz communication is one of the key technologies that will enable 6G communication.
The CASC team’s experiment is a major step forward in the development of 6G communication technology in China. It demonstrates the feasibility of terahertz communication technology and paves the way for the commercialization of 6G communication in China.

Benefits of 6G Communication Technology
6G communication is expected to offer a number of benefits over 5G communication. These benefits include:
- Higher data rates: 6G communication is expected to offer peak data rates of up to 1Tbps. This is significantly higher than the peak data rate of 5G communication, which is 10Gbps.
- Lower latency: 6G communication is expected to have lower latency than 5G communication. Latency is the time it takes for data to be transmitted from one point to another. Lower latency is important for applications such as real-time video streaming and virtual reality.
- Greater capacity: 6G communication is expected to have greater capacity than 5G communication. Capacity is the number of devices that can be connected to a network at the same time. Greater capacity is important for applications such as smart cities and the Internet of Things.
